With the carcass layer associated annular structure comprising inextensible circumferentially annular insert that is located axially on the outer side relative to the anchor element. Design in the form of a tape, the tape of the tread and side walls United with formed so design framework for education bus, which is then subjected to vulcanization. This increases the durability of the tire. 3 S. and 29 C.p. f-crystals, 19 ill.

The present invention relates to a tyre for a vehicle, comprising: a framework having at least one layer of osenia, each of them is mainly in the U-shaped profile in transverse section of the tire, and a pair of inextensible around the circumference of the ring-shaped structures, each of which is attached close to respective inner circumferential edge of the layers of the frame; the design of the ribbon attached to the framework in its outer circumferential position; braid protector applied to the design of the tape in its outer circumferential position; at least one pair of side walls attached to the framework at opposite side positions.

The manufacture of tyres for the wheels of the vehicle includes the implementation of a design framework, mainly consisting of one or more layers of the framework, mainly having a toroidal shape, and axially spaced opposite side edges which are fastened relevant district inextensible annular reinforcing elements, called "side mandrels".

The circumference of the outer side of the frame is tape construction comprising one or more strips of tape in the form of a closed ring, mainly consisting of textile or metal cords oriented appropriately relative to each other and otnositelnoy elastomeric material of appropriate thickness, attached to the belt construction on its circumference from the outer side. It should be noted that in accordance with the purposes of the present invention, the term "elastomeric material" means the rubber mixture as a whole, i.e. the node is made of a base polymer, accordingly amalgamating mineral fillers and/or additives of any other type.

Finally, on the opposite side of the manufactured tire is a pair of side walls, each of which closes the side area of the bus, connected between the so-called shoulder region located close to the corresponding lateral edge of the ribbon protector, and the so-called protector, located on the corresponding side Dorn.

In accordance with traditional manufacturing methods of the above components tyres are first manufactured separately from each other for subsequent Assembly during manufacture of the tire.

For example, for the manufacture of a layer or layers of the frame, which should be associated with airborne mandrels to form a design of a frame, first and foremost requires the production of rubberized fabric comprising longitudinally spaced continuous textile or metal cords, through the I to obtain the lengths of predetermined size, which, basically, are connected together, constituting the basis of a continuous band-shaped semi-finished product having transversely spaced parallel cords.

Then it made the product must be chopped to pieces, the length of which is correlated with the circumferential length of the frame that you want to perform.

Recently methods have been proposed in which, instead of resorting to the production of semi-finished products, the design of the frame perform directly during manufacture of the tire.

For example, in patent US 5453148, shown herein as an example of the closest solutions from the prior art, presents the method and device according to which the design of the frame is performed by placing a single continuous filament in accordance with an alternative trajectories placement sequentially side by side in the circumferential direction on the toroidal support having a shape corresponding to the shape of the inner surface of the tire, you want to make.

In more detail, the toroidal support is first covered with a layer of raw rubber that performs a dual function, namely, quality of the adhesion of the coated thread to keep it separate marked cell bus.

A separate thread is drawn directly from the coil, is captured by a sliding elements, leading her to a roaming guide, working on the toroidal support. Roaming the guide element moves along the path of the slide, has a section of the translational movement and the partition of the return movement, which are connected to each other for the formation of the infinite line lying in a plane radial with respect to the toroidal support. Each of the sections of the forward and return movement extends mainly in the form of an element of the C-shape around the cross-sectional profile of the toroidal support.

Thus, each time the guide element closes one of the partitions onward or return travel path of the slide, it causes the application thread on the toroidal support, thus creating a put section, which is U-shaped around the profile in transverse section of the toroidal support. When the instantaneous interference between the formation of one of the applied sections and the subsequent formation damage section of the toroidal support is rotated by a predefined angle, preparing devices is p> Exciting fixtures using fork elements carry out the seizure of the threads in the outer region of the newly formed applied section to prevent broaching along the latter at the expense of the guiding element during the initial formation and subsequent damage to the partition. Holding device with the use of push elements have a positive effect in the area of transfer between two successively applied sections, making them marginal rim tape to stick to the side surface of the toroidal support.

Tyres are generated in such a production method, have the design of the frame, in which the cords forming the layer or layers of the framework consist of a single threadlike element, forming a set of consecutive sections, transverse with respect to the bus, arranged in parallel side by side in the circumferential direction and applied in respectively opposite directions to get the rotation.

Within the scope of the manufacture of the framing, as you can see on the basis of patents EP 0684231 and EP 0884232 by the partition formed by the individual threadlike elements must also be placed in izabranih anchor elements, the components of the above side mandrels.

With reference to the reviewed drawings and specifically to Fig.1 and 17 tire for a wheel of a vehicle in accordance with the present invention, generally designated by the number 1.

Bus 1, mainly includes the construction of 2 frame having at least one layer 3 of the frame, mainly toroidal shape and is bonded with the opposite circumferential edges, with a pair of inextensible annular structures 4, which, when the tire is fully assembled, are in the field, usually referred to as "the Board".

To the design of the frame 2 on the outer circumferential surface of the attached design 5 in the form of a tape, comprising one or more strips 6, 7 in the form of a tape. Braid 8 tread superimposed on a circle on the structure 5 in the form of a tape, and longitudinal and transverse sections 8A made in the above braid protector 8 after the forming operation carried out consistent with the vulcanization of the tire, and are thus to determine the appropriate "tread pattern".

The bus also includes a pair so nazivaemie 2 of the frame can be covered on its inside wall of the airtight layer 10 of elastomeric material, that is, the so-called "lining", mainly consisting of a layer of elastomeric material impervious to air, adapted to ensure the tightness of the inflated tire.

The Assembly of the components listed above, as well as the making of one or more of the above components was performed using the toroidal support 11, schematically shown in Fig.2 and 3 having the same configuration as the inner wall of the tire, you want to make.

When the preferred solution of the toroidal support 11 has a reduced size relative to the size of the finished tire in accordance with the linear size, preferably comprising from 2 to 5%, when measured, exactly as shown, along the circumferential ledge of the support in its Equatorial plane x-X, which coincides with the Equatorial plane of the tire.

The toroidal support 11, which is not described nor illustrated in detail, since it has no special meaning for the purposes of the present invention, may, for example, consist of a split drum, or pumped from the camera, or of the elastic cylinder, reinforced so that she could take and hold the required toroidal shape in terms of Nakajima is of the structure 2 of the frame, since the possible formation of the airtight layer or sheath 10.

It is advisable that the plate 10 was performed using a circular winding around the toroidal support 11, at least one braid 12 of airtight elastomeric material from the extruder and/or from the calender, located close to the toroidal support. As can be seen from Fig.1, the winding of the webbing 12 is usually in the form of circular coils arranged in series side by side to match the cross-sectional profile of the outer surface of the toroidal support 11.

For expository purposes, the term "cross-sectional profile" in this document means the configuration, which is a half-section of the toroidal support 11 formed in the sectional plane that is radial with respect to the geometric axis of rotation, not shown in the drawing, which coincides with the geometric axis of rotation of manufactured tires.

Coordinated with the winding of the ribbon 12 may be mounting a pair of additional annular elements 12A close to inner circumferential edges of the frames during a stage of its manufacture. Each of these additional annular is OK by side with the corresponding coil, located on the inner edge around the perimeter of the plates 10, which are formed or to be formed on the toroidal support 11. In contrast, the additional annular elements 12A may be made of at least one braid obtained from the corresponding extruder located on the toroidal support 11.

In accordance with the present invention the layer 3 frame is made directly on the toroidal support 11 by applying it on alternate paths, at least one element 13 in the form of a strip, preferably having a width of from 3 to 15 mm, which is better explained as follows.

As shown in Fig.4, the preparation of the element 13 in the form of a strip, basically, means that two or more threadlike element 13A, and preferably from three to ten threadlike elements 13A, supplied with the respective coils 14, should be directed through the first extruder 15 associated with the first extrusion device 16 engaged in the supply of raw elastomer material through the extruder.

It is noted that in the present description, the term "extruder" is meant that part of the extrusion device, also referred to in this concretecost, processed on the output hole that has a shape and size in accordance with geometric and spatial characteristics of the product itself. Elastomeric material and elements 13A connected to the inside of the extruder 15, thus forming a continuous element 13 in the form of stripes on his way, and the element is made of at least one layer of elastomeric material 13b, the thickness of which is included themselves threadlike elements.

Depending on your requirements, you can send threadlike elements 13A in the extruder 15 in such a way that they are not entirely included in the layer of elastomeric material 13b, a appear on one or both of its surfaces.

Threadlike elements 13A may each be, for example, of textile fabric, preferably having a diameter of from 0.6 to 1.2 mm, or metal cords, preferably having a diameter from 0.3 to 2.1 mm

Preferably, if necessary, threadlike elements 13A could be placed in the element 13 in the form of stripes so that they provide a layer 3 frame, thus obtained, unexpected qualities of compactness and homogeneity. For this purpose, threadlike elements 13A can be, for example, placed as desired is close to the Equatorial plane x-X of the tire 1. In any case, it is preferable that the threadlike elements 13A were placed in the element 13 in the form of a strip when the distance between their centers is at least 1.5 diameters themselves threadlike elements to ensure proper operation prorezhivanija between adjacent threads.

Solid element 13 in the form of a strip emerging from the extruder 15, mainly, can be optionally directed through the first heat-sink-compensating device 17 on the device 18 for drawing, which schematically represented in Fig.2 and 3.

The device 18 for applying mainly includes guiding elements 19, consisting, for example, of a pair of rollers mounted on a stationary axis of rotation and designed to capture solid element 13 in the form of a strip produced by the extruder 15. Moving from the first guide elements 19, the element 13 in the form of a strip comes into contact with the second guide elements 20, comprising, for example, from other rollers mounted on the carriage 21, reciprocating movement in a direction oriented transversely to the Equatorial plane x-X of the toroidal support 11. For example, at least one distribution element 22, including the other valiyapally move the carriage.

Components that are designed to connect to each other and moving the distributing element 22 and a movable carriage 21, not shown in the attached drawings, as they may be made in any manner convenient to the specialist, and in any case they are irrelevant for the purposes of the present invention.

Due to the combination between the transverse movement of the carriage 21 and the radial displacement distribution element 22 of the distribution element can be moved back and forth along the trajectory "t", corresponding mainly U-shaped cross-sectional profile of the toroidal support 11.

The toroidal support 11 can be brought into an angular rotation in a phased move synchronously with the movement of the distributing element 22 so that the element 13 in the form of a strip is applied to a toroidal support in a consistently applied sections 23, 24 bus, arranged in parallel side by side in the circumferential direction and aligned with respectively opposite directions to provide the rotation.

Specifically, each of the plotted sections 23, 24 is located in accordance with a U-shaped cross-section profile of the toroidal support 11, forming two sides of Rodley support at a distance from each other in the axial direction, the vertex section 23b, 24b is located radially on the outer side with respect to the side portions 23a, 23C, 24A, 24C.

For convenience of description by the partition obtained by moving from right to left of the applied element 22, as shown in Fig.2 and 3, will hereinafter be called the first done by sections 23. The partition obtained by moving the divider element in the opposite direction, will instead defined as the second applied section 24.

In more detail, the sequence of application item 13 in the form of stripes on the toroidal support 11 is as follows. The beginning of the operation, as expected, takes place in the initial situation, when, as shown in Fig.2, the distributor element 22 is in its left position at the end of the path of travel "t". Starting from this position, the distributor element 22, in the main, is moved radially from the geometric axis of rotation of the toroidal support 11 for the formation of the first side section 23a of the first applied section 23.

Thanks to the stickiness of raw elastomeric material forming the layer 13b covering the threadlike elements 13A, the stable adhesion by Elna support. In the case when, as schematically shown in Fig.2 and 3, the toroidal support 11 has a side sections 11a concave profile, which are located in areas corresponding to the side walls of the manufactured tire, the above-described adhesion takes place, as soon as element 13 in the form of a strip comes into contact with the toroidal support in a radially outer region of the cross-section profile.

In addition to or instead of the above-described use of the natural stickiness of elastomeric material holding element 13 in the form of stripes on the toroidal support 11 can be achieved by suction through one or more apertures 28 located on the toroidal support.

At the initial stage of the turn of the distribution element 22 from the geometric axis of rotation of the toroidal support 11 element 13 in the form of a strip is bent relative to itself, forming a region 25 of the curve representing the transition between the first side section 23a of the applied section 23, which is to be formed, and the second side section 24b owned previously formed by the partitions 24. During the formation of the first side section 23a element 13 in the form of a strip is conveniently held in the above region 25 projectors is it.

Consistent with the formation of the first side section 23a of the toroidal support 11 is rotated around its geometric axis of rotation relative to the distribution element 22 in accordance with the tilt angle, which corresponds to half the step angle distribution around the circumference of the applied sections 23, 24. Accordingly, the first formed by the side plot will take a correspondingly inclined position relative to the direction of movement, which is carried out using a distribution element 22 from the geometrical axis of rotation of the support.

In the embodiment of the present invention, which is schematically shown in Fig.2, where the angle distribution around the circumference of the individual damage of sections 23, 24 corresponds to the width of element 13 in the form of strips, step-by-step rotation of the toroidal support 11 will correspond to half the width of the element in the form of a strip.

In any case, it may be provided with angle distribution around the circumference of the applied sections 23, 24, a multiple of the width of the element 13 in the form of a strip. In this case, the step angle of rotation of the toroidal support 11 is in any case to correspond to half of the angle distribution around the circumference. You noted who belongs to the circle, lying in the Equatorial plane x-X and close to the outer surface of the toroidal support 11.

When the reference element 22 is approaching the top of its stroke from the geometric axis of rotation of the toroidal support 11, moving the carriage 21 moves in the direction from left to right in accordance with Fig.2. Under these circumstances, the distributor element 22 is moved in a direction mainly parallel to the geometric axis of rotation of the toroidal support 11 in such a way that in a position radially external to the latter, the formation of the apical section 23b made by the section 23.

When the carriage 21, in the main, completed the move status, distribution element 22 is moved in a generally radially close to the geometric axis of rotation of the toroidal support 11. Thus is formed the second side section 23C of the first applied section 23.

Consistent with the formation of this second side section 23C of the toroidal support 11 is rotated relative distribution element 22 when the value of the step-by-step rotation angle identical carried out previously.

When the distributor element 22 completes its move move near geometries the th element 28 holding and placed the mirror relative to the first, located along the second side section 23b, which has just formed in the same manner as shown in phantom line in Fig.3 in connection with the element holding 26 located on the opposite side.

Preferably, the element 28 retention then moved in the lateral direction close to the toroidal support 11, ensuring the passage of the distributing element 22 as it moves upward, resulting in consistent with the formation of the first side section 24A of the new second applied section 24, the element 13 in the form of a strip is rotated backward relative to the element holding, thus forming a new region 25 of the bend.

Simultaneously with the formation of the first side section 24A of the second applied section 24 of the toroidal support 11 carries out the following step-by-step rotation, which, when added to a step-by-step, carried out during the deposition of the second side section 23b of the first applied section 23, prepares a distribution element 22 to the formation of the apical section 24b of the second applied section 24 in position at a distance from the previously formed by the section 23 in accordance with the desired step angle.

The element 26 to hold the ski at this stage there is a warranty, what element 13 in the form of a strip comes into contact with the surface of the toroidal support 11 at a point down towards education just formed the first side section 24A, and that it has no tendency to undesirable shifts, which could distort the geometry of the application element in the form of a strip.

As soon as the element 26 holding stretches from the area 25 of the bend, the side sections 23C, 24C of the applied sections 23, 24 can be provided for stage clamp relative to the side walls of the toroidal support 11. For this purpose may be provided with a pair of pinch rollers 27 or equivalent devices, and they work on opposite sides of the toroidal support 11, and each of them is a repeat operation on the first and second side sections belonging to two adjacent dealt sections.

In Fig. 3 is a schematic representation of only one of these pinch rollers 27.

The above described operating sequence of the device 18 for applying allows you to apply the apical sections 23b, 24b of each of the applied sections 23, 24 in the output layer 3 frame sequentially side by side along the circumferential ledge of the toroidal support 11, while the side sections 23a, 23C, 24A, 24C each applied behold the SIMA section.

More specifically, the first side section 23a, 24A of each of the applied sections 23, 24 are partially superimposed on a second side section 23C, 24C previously formed by the partitions 23, 24.

As clearly shown in Fig.6, the side sections 23a, 24C in the mutual overlap are moved relative to each other in the direction of the geometric axis of rotation of the toroidal support 11 in accordance with the anglewhose value is correlated with the width "L" of the element 13 in the form of a strip and, in any case, with the angle distribution around the circumference of the applied sections 23, 24, and with the difference between the maximum radius R' and the minimum radius R, which is the maximum and minimum distances, respectively, from the geometric axis of rotation of the toroidal support 11.

Due to the mutual convergence between the first and second adjacent side sections 23a, 24C and 24A, 23C their mutual overlap is reduced, since the maximum value of the radial inner edges of the side portions where the above sections there are in the area 25 of the bend, until the zero values in the transition region between the side sections and terminal sections 23b, 24b.

It should be noted that due to the difference between the minimum and maximalistic in the district section of given length will tend to increase when moving to the geometric axis of rotation of the toroidal support 11.

This increase in density is proportional to the ratio between the maximum radius R' and the minimum radius R.

However, in the tire made in accordance with the present invention, the mutual overlapping of the side portions 23a, 24C and 24A, 23C allows to halve the average density, measured along the inner circumferential edges of the received layer 3 frame, i.e. in the areas 25 of the bend.

In this circumstance the field 25 of the bend will be connected to each other in the circumferential direction, allowing a homogeneous distribution of threadlike elements 13A along the inner circumferential edges of the layer 3 frame, only if the ratio between the maximum diameter R' and a minimum diameter of R is 2.

When in contrast, as it usually is, the ratio between the maximum radius R' and the minimum radius R is less than 2, sections 25 of the bend will have a tendency to be in accordance with the step-by-step angle at the circumference is greater than the width of the element 13 in the form of a strip, forming an empty space between one region 25 of the bend and the other obliku structural homogeneity of the layer 3 frame near the inner circumferential edges of the layer 3 frame, provided the stage clamp for consistent implementation on the element 13 in the form of stripes in the areas of its longitudinal extent in accordance with the side sections 23a, 23C, 24A, 24C to form a region of increased width L', longest element in the form of a strip, and these areas are located on the inner peripheral edges of the formed layer 3 frame.

The aforementioned clamping action can be performed, for example, with the pinch roller 29 mounted movably on the carriage 21, and adapted for selective installation in motion by the actuator 30 for compression element 13 in the form of a strip on one of the rollers, which is part of the second transport unit 20.

The actuator 30 is sequentially activated during application of the element 13 in the form of a strip, to cause compression in the above sections of the longitudinal protrusion intended for education side portions 23a, 23C, 24A, 24C. The impetus carried out by the actuator 30 may be carried out to obtain ever-increasing pressure steps, for example, after you move close to the areas 25 of the curve and constantly decreasing steps when moving from them. The action of compression used will cause movement of threadlike elements 13A in different directions.

By enabling measurement of action in the form of impetus carried out using the actuator, the width of the element 13 can be increased to a value of L', which creates the corresponding each area 25 of the bend with the neighboring regions of the bend.

With the help of the tilt orientation of the geometric axis of rotation of the toroidal support 11 relative to the direction of movement of the moving carriage 21 apical sections 23b, 24b of the applied sections 23, 24 can receive the necessary slope, preferably comprising from 0 to 15oand more preferably, 3orelative to a radial plane passing through the geometric axis. It should also be noted that due to the rotation stages, carried out by the toroidal support 11 consistent with the formation of each of the applied sections 23, 24, the side sections 23a, 23C, 24A, 24C applied sections will be inclined at an angle/2 relative to a radial plane intersecting themselves side sections, with the first side sections 23a, 24A have the opposite direction of inclination with respect to the second side portions 23C, 24C.

Perform design 2 frame typically includes the step of attaching the above inextensible annular con is pour the creation of areas of the frame, known as "the Board" which are specifically designed to attach the tire to a corresponding mounting rim; in accordance with the preferred implementation of the bus layer frame is received as described above.

Each of these inextensible annular structures 4 (Fig.7) includes a corner anchor element 31 of the type called "onboard the mandrel, which may be performed, for example, from one or more metal wires, bent together or wound side by side in turns to create a profile, mostly round or square cross-section.

In accordance with a preferred embodiment of the present invention inextensible circumferentially annular insert 32 is combined with the onboard mandrel 31 and is located approximately in a plane parallel to the adjacent surfaces of the layer 3 frame along the radial protrusion defined by the difference between the minimum internal radius and the maximum external radius of the annular insert, preferably equal to or, at least twice the radial length of the side of the mandrel 31, or, in any case, more of the latter.

In the first embodiment, constraints on the outer side relative to the side of the mandrel 31. In other words, the annular insert 32 is located with respect to the aircraft, the mandrel 31 is opposite relative to the Equatorial plane X-X.

In a possible opposite solution shown in Fig.18, inextensible annular insert 32, on the contrary, is located axially inside relative to the side of the mandrel 31, i.e. on the side facing towards the Equatorial plane X-X. In this case, the annular insert 32 is preferably mainly in contact with the adjacent layer 3 frame.

The annular insert 32 is made of at least one metal wire is wound for the formation of multiple concentric coils 32A. The coils 32A can be formed by a continuous spiral or concentric rings formed of respective metal wires.

Preferably, during use of the tire inextensible annular insert 32 is adapted to effectively counteract the tendency of the Board to rotate relative to the cross-sectional profile of the onboard mandrel 31 under the influence of moving shocks, directed parallel to the axis of rotation of the tire 1. This tendency to rotate is particularly evident when the tire is used under conditions of partial or panagariya annular insert 32 is formed within the cavity 34 of the mold by applying, at least one thread-like element in the form of concentric coils 32A, located side by side in accordance with circles of increasing diameter relative to the geometrical axis of the winding in accordance with the rotation axis of the tire.

This work should be carried out by winding thread-like element in a spiral slot, located on the first cheek 34a molds 34a, 34b, which for this purpose can be brought into rotation about its geometric axis.

It is advisable that the application stage threadlike element is preceded by a stage of prorezhivanija, in which the threadlike element, preferably of a metallic material covered with at least one layer of raw elastomer material, which in addition to providing excellent ligament rubber-metal at the threadlike element provides its adhesion to sustainable accommodation in the above-mentioned spiral slot.

The first cheek 34a may also be made of magnetic material or to be magnetized to attract and retain the threadlike element, providing, thus, a stable positioning of the coils 32A, formed by them.

Then Board the mandrel 31 forms is carried out by moving the first cheek 34a close second corresponding cheek 34b. The cavity 34 vulcanizing form then filled up raw material, adapted for the formation of the filler 33, internally connected to the onboard mandrel 31 and inextensible circumferentially annular insert 32.

Preferably, the filling of the cavity 34 of the mold was carried out by injection of raw elastomeric material through at least one annular injector comprising an inlet hole or hollow space 35, generally extending over the entire circumferential ledge cavity of the mold. Thus, there is a rapid and uniform filling of the cavity 34 of the mold without the risk stratification phenomena that can occur in elastomeric material, if the latter will pass through the inlet channels of reduced cross-section. It should be noted that the inlet hollow space 35 may consist of multiple cracks, uniformly distributed along the entire circumferential ledge cavity 34 of the mold, in order to ensure the possibility of rapid and uniform filling of the cavity of the mold.

The execution of the inextensible annular structures 4 may predominantly take place close to the toroidal support 11, so that the x mechanical handling devices, which are not described herein so as not important for the purposes of the present invention.

When attaching the inextensible annular structures 4 is completed, either the layer or layers of the frame, or as specified within the scope of the present invention, the side sections 23a, 23C, 24A, 24C applied sections 23, 24 are provided with respective edge flaps, radial in the direction of the geometric axis of rotation of the toroidal support 11 relative to the inextensible annular structures. These regional flaps, mainly close to the above areas 25 of the bend, turn backward relative to the respective inextensible annular structures 4, as shown in Fig.8.

This phase reversal can, for example, be carried out with the help of inflatable chambers or equivalent devices associated with the toroidal support 11. The amount by which protrude above the regional flaps, and, consequently, the width of the turned back flaps, formed above, can be easily installed in advance by appropriate adjustment of the stroke of the distribution element 22 and the radial positioning of the holding cell battery (included) the functions 2 frame may include education, at least one additional layer frame, not shown in the attached drawings. This additional layer of the frame can be made directly superimposed on the layer 3 frame and inextensible annular structures 4, as well as the primary carcass layer, optionally with applied sections, spaced cross in relation to the applied sections 23, 24, forming a first layer 3 of the frame.

In the tires of the radial type structure 5 in the form of a tape currently attached to the structure 2 of the frame.

Mainly if there are signs of novelty and inventive step attachment structure 5 in the form of a tape is directly on the structure 2 of the frame, which in the preferred embodiment of the present invention may be performed as described above.

For this purpose, as schematically shown in Fig.9 and 10, is provided by the formation of at least one continuous braid 36 in the form of a tape, which includes a plurality of longitudinal parallel cords 36A, for example, from a metal material, at least partially included in one or more layers of raw elastomeric material 38b.

The formation of a continuous tape 36 to 37 through the second extruder 38, which receives the elastomeric material from the second extrusion device 39. Continuous tape 36 in the form of a tape extending from the second extruder 38, after the eventual passing through the first pressure rollers 40 calender is conducted through a sawing machine 41, cutting her in line with the given slopewith respect to its longitudinal length to form the segments 42 of the tape width when measured perpendicular to the cutting direction corresponds to the width of the at least one first strip 6 in the form of a tape, which must be obtained on the structure 2 of the frame.

The segments 42 are individually and sequentially stacked on the structure 2 of the frame and, therefore, fit the circumference of the side by side along the respective connection edges 42A parallel Kardam 36A and in accordance with the longitudinal edges of the tape 36 in the form of a tape.

Therefore, the node of the segments 42 forms a first strip 6 in the form of a continuous tape of the district stretch, as schematically shown in Fig.11, and the first strip 6 in the form of a tape cords 36A will be located transversely to the slope corresponding to the slope of the cutting segments 42.

This inclination preferably has a value, sootvetstvuyuschengo, additionally, with the opposite orientation relative to the underlying layer 3 frame.

To the first strip 6 in the form of a tape consisting of segments 42 of the same layer may have a uniform and continuous direction, solid braid 36 in the form of a tape extending from the second extruder 38 may have a transverse dimension, measured parallel to the direction of cutting equal circumferential size of the first strip in the form of a tape. In the opposite variant, the transverse size may be somewhat lower than the value of the above amount, being then suitably increased by using a calendering operation carried out by the rollers 40.

As a conclusion, through the impact on the rollers 40 calender width of clear tape 36 in the form of a tape can be adjusted so that the resulting segments 42 will be of a size corresponding to the size of the share in the circumferential direction for the band 8 in the form of a tape, without having to replace the extruder 38.

It should be noted that using the calendering operation is achieved by increasing the distance between the individual cord 36A consistently with increasing width of the continuous band 38 in the form of a tape, and the above-mentioned cords 38A stability operations may be repeated in the same way, if you want the formation of one or more additional strips in the form of a tape, not shown in the attached drawings, cords which are inclined in accordance with the cross-orientation towards Kardam 38A of the first strip 6 in the form of a tape and/or adjacent bands.

In the method, which is known in itself, the formation of the first strip or strips 6 in the form of a tape may be preceded by attaching two inserts 43 in the form of a strip adapted to maintain the side edges of the first bands in the form of a tape, so that the latter can basically save a flat profile in cross section.

Therefore, at least one second band 7 in the form of a tape made preferably by winding at least one continuous elongated element 44 in the form of coils arranged axially side by side and protruding circumferentially relative to the first strip 6 in the form of a tape.

If you wound coils formed long element 44 may be located side by side in alternating axial course of the distribution, which, for example, closer to the median Equatorial plane x-X of the tire than to the opposite side edges of the structure 5 in the form of a tape.

As schematics is applied from the respective coils 45, connected in parallel with each other and rubber protected by passing through the third extruder 46 is provided with an elastomeric material with a third extrusion device 47.

Long element 44, thus obtained, consists of one or more source cord 44a, covered with the elastomeric material of the proper thickness, and is ready to be wound around the first strip 6 in the form of a tape after the eventual passing through the device 48 for storage.

In a convenient embodiment of the present invention the above cords are well known metal cords type NO (high ultimate elongation), the use and characteristics of which have already been described in detail, for example, in European patent 0461484 the same applicant.

In more detail, these cords are composed of a given number of strands, and each strand is made of a given number of individual wires with a diameter of not less than 0.10 and not more than 0.40 mm, preferably in the range from 0.12 to 0.35 mm Wire in the strands and the strands in a rope wound together in a spiral in the same direction, and the steps for winding wires and strands may be the same or different.

Preferably these cords are made of vicariance implementation of the present invention, particularly favorable in the case of tyres for road transport, the above winding spiral layer is preferably from a single cord, known as HH,20 NT cord wound in a spiral from one tape edge to the other: the above indication determines metallic cord made of three strands, each of which consists of four elementary wires with a diameter of 0.20 mm is wound in the same direction as the strand; then, as is well known, the reduction does NOT mean "a high degree of elongation, and reduction of NT means "high tension".

These cords have a minimum elongation of 4 to 8% and is well known for the typical behavior under tension, the so-called "behavior of a spring.

In an alternative embodiment, the present invention specifically adopted for hire, the above winding is made with textile cord, preferably of a material which is compressible when heated, such as NYLON 6 or NYLON 66.

Then braid the protector 8 is attached to the structure 5 in the form of a tape obtained by the method described above.

In more detail, in accordance with the following characteristic of the present ODI, at least one continuous sheet 49 of raw elastomeric material around the structure in the form of a tape in the form of a set of radially superimposed coils, as schematically shown in Fig.15.

A continuous sheet of elastomeric material appropriate to comply with the fourth extruder 50 when filing with the fourth extrusion device 51. Sheet 49 extending from the fourth extruder 50, can be captured in the following block 52 calender, immediately after which can be located toroidal support 11, the carrier made the bus in order to provide immediate winding sheet of elastomer around the structure 5 in the form of a tape.

With appropriate slicing devices associated with the block 52 calender and/or overlapping devices operating on the output of the fourth extruder 50 (both devices are not shown, as they may be made of any design, convenient specialist), the width of the sheet 49 of elastomeric material, it is advisable to gradually reduce consistently with the formation of each wound coil "S" around the structure 5 in the form of a tape, so that the elastomer sheet has a width gradually decreasing from the axis of rotation of the tire 1. Estestvennaya remote coils, to make the braid 8 tread the transverse profile.

After making the ribbon 8 tread or additionally, prior to this work step is attaching the side walls 9, performed schematically, as shown in Fig.16 and 17. In the shown embodiment, each side wall 9 is made by injection of elastomeric material into another mold 53, from which the above-mentioned side wall is removed and then attached to the side of the structure 2 of the frame by means of mechanical manipulation devices or other similar devices.

In the shown embodiment, each side wall 9 has a radial outer section 9a and a radial inner section 9b made of various types of elastomeric material and internally connected to each other by means of the process perforovane. With this purpose, the mold 53 is an external cheek 53A and a pair of inner cheeks 53b, which are interchangeable, and in the drawings only show one of them.

External cheek 53A first connected with the first inner cheek (not shown) for formation of the first cavity inside the mold, and in this cavity through the injection pass-shape 53 is then replaced with the second inner cheek 53b, having such a form that the mold forms a second cavity partially bounded previously formed radially outer section 9a. This is the second socket is designed to receive the radial inner section 9b, which is made by injection of the second elastomeric material.

Each of the side walls 9, formed in the above manner, allows for lateral attachment to the structure 2 of the frame, as described above.

Bus 1, made so, now ready for removal from the toroidal support 1 and to the stage of vulcanization, which may be carried out by any known and convenient manner.

In accordance with a possible alternative implementation of the air tube in the form of a closed tubular section may preferably be connected to the bus 1 in addition to the plate 10 before or after the step of vulcanization, and the air tube is inserted in the frame 2 after removing the tire from the toroidal support 11. This air tube, not shown in the attached drawings, will be inflated after the introduction of the tire vulcanizing the form for filing an internal pressure, adapted to ensure the quality of adhesion of the tyre against the walls of the mold and, specifically, regarding the accordance with another preferred feature of the present invention during a stage of vulcanization layers 3 of the frame and the strip 6, 7 in the form of a tape passing through the stage of stretching to achieve the pre-tension, providing extension bus in a linear direction, as measured by the district projection in the Equatorial plane x-X of the tire, of the order of 2-5%. This stage stretching may be carried out using the inflation pressure of the above pneumotropica or other inflatable chamber or aperture in a vulcanizing device.

The present invention provides important advantages.

Actually, this tire can be obtained by the manufacture of the various components directly on a toroidal support, which gradually formed a tire or, in any case, very close to it. Thus, all the problems associated with the manufacture, storage and manipulation of semi-finished products, so common in the manufacturing processes of the traditional type, are eliminated.

It is important to note that the formation of the layer or layers of the framework by applying element in the form of a strip, made of several cords included in one elastomeric layer, achieves important advantages. First of all, in comparison with the methods described in the above patent US 5453140, vremove number of threadlike elements, which is contained in the element 13 in the form of a strip. The use of element 13 in the form of a strip is also carried out in accordance with the provisional application of the lining 10 on the toroidal support. Really layer 13b of the elastomer used in the formation of the element 13 in the form of a strip, by itself, can provide effective adhesion element 13 relative to the toroidal support 11, providing, thus, a stable positioning of the individual damage of sections 23, 24.

Positioning accuracy is related to the applied sections and threadlike elements entered into them, further enhanced by the fact that the element in the form of a strip has such a structure that makes it insensitive to vibrations or other similar vibrations that can be transmitted through the device 28 for applying. In this regard, it should be noted that the application of individual threadlike element, as described in patent US 5453140 makes it difficult to achieve precision application of each threadlike section due to vibrations and/or oscillations, which is subjected to the above thread during the application stage.

Moreover, the simultaneous application of many threadlike elements in accordance with the present invention I am applying a separate thread, that is another advantage associated with the accuracy of work without reduction, on the other hand, performance.

In addition, the printing element in the form of a strip directly on top of the toroidal support profile respectively identical with the ready bus allows to achieve density, which is impossible when using methods known from the prior art, providing application layer frame in the form of a cylindrical sleeve and the subsequent giving of the aforementioned toroidal form, which will consequently lead to thinning of the cord layers of the frame, located on top of the finished tyre.

In addition to the above, the element in the form of a strip can be stably attached to the toroidal support using the vacuum effect that is obtained through the possible suction passage 28, and a stable mount this item cannot be achieved by the application of known processes of applying for a separate thread.

The inclined arrangement of the side portions 23a, 23C, 24A, 24C provides the extension, which is exposed to the tire during the stretch, which is necessary for the effective implementation of vulcanization. Actually, during this ATAPI sections 23b, 24b extending between the side sections. The overlap side portions near to the axis of rotation of the tire substantially strengthens the design of the tyres close to the protectors, where usually require high structural strength.

Attention is also drawn to the original character designs inextensible annular structures 4, located on the protectors. Specifically, due to the presence of inextensible circumferentially annular inserts 32 in combination with the usual side mandrels 31, the tendency of the Board to rotate under the influence of moving shocks effectively prevented. In the prior art, this phenomenon has led to slippage of appropriate protective bus jumper, located in the rim, especially when the tire is subjected to rolling tremors in partial pumping air. By installing a ring-shaped inserts 32 this disadvantage is eliminated, and the bus can be used even in conditions of almost complete pumping air without undesirable movement of the Board from its slot.

The behavior of the tire bead in accordance with the present invention during movement when the slide is schematically represented in Fig.19, gdeda from the sides of the tires has a socket a Board, axially limited by a flange 58 forming an outer lateral edge of the rim and protective jumper 57. For clarity in Fig.19, which shows the tire 1, the shading section is not specifically applied. As can be clearly seen in the above figure, the presence of the inextensible annular insert 32 prevents rotation of the tire bead under the influence of the sliding push N directed parallel to the axis of the tire rotating on its reliance on the defence jumpers 57 installed in the rim 54. In this situation, the sliding push N acting along the layer 3 frame, until convergence with the rim 31 of the side, causing the rise of the radial component N1, which tends to move the Board out of the slot 55 of the Board and be counteracted by the district derestimate annular structure 4, and the axial component N2, which tends to push the Board regarding the district flange 56, providing support to the sustainable positioning of the above.

Thus, the tire having a bead made in accordance with the present invention, can withstand the so-called "test curve J" without removing the Board from its slot until the inflation pressure of 0.5 bar, while in the prior art is itausa acceptable.

It should also be noted that the annular insert 32 provide additional protection to the tyre construction on the sides.
