This invention relates to an insulation product having two major surfaces and a thickness between these two surfaces and including a layer of insulating material and at least one elongated fixing means for fixing the product, these locking means are stretched in the first direction, essentially parallel to at least one of the main surfaces, and allow you to secure the product on the isolated structure and/or on adjacent walls.

It is well known that for energy-saving buildings, pipelines and other structures provided with insulating coatings. Over time, have created a very effective isolation device in the form of a partition of the fibers or foam derived from inorganic or polymeric organic materials. Increased attention to energy saving and the widespread use of such materials has also led to effective methods of production of such insulating materials, with benefits for consumers and the environment have reduced their rates.

However, a significant proportion of the cost of isolating the various structures necessary for the period of installation of the insulation material. Many designs that can benefit from isolation, are not readily available or have other properties that make the procedure of isolating unreliable, and is therefore expensive. In fact, it does not cover the isolation of many designs, which leads to undesirable energy loss.

In particular, insulation of pipes, vents and other structures of the closed section is unreliable, because the insulating material cannot normally be directly attached to such structures using screws, nails and the like. Alternative methods, such as gluing, also often impossible because of the high temperatures of the surfaces of the structures, the flammable range and/or medical reasons.

One of the most common ways to isolate the structures of the closed section with the use of insulation products is the use of more or less prepared in advance of the pipe sections. However, for large or custom designs, or designs with a non-circular cross-section cannot obtain reliable pre-prepared pipe sections, it is also known the use of mats, for example, partitions of an insulating material, and the wrapping of one or more of these partitions, with a total length corresponding to the circumference of the structure, around the structure so that both end walls in contact or overlap, and then using tie-wire manual strapping around the walls for at least vremennogo the fixing partitions in the design. In particular, for this purpose, use a sheet of mineral fibers, and often they are supplied with the cell grid with one hand to hold the sheets and to facilitate its capture and fixation. This product is cell grid described in the patent WO 95/27095.

In this way, the design along the entire length can be covered with successive overlapping of sheets, where the total length of the sheets corresponds to the length of the structure. For structures of a large circle in the technique is also known connection of multiple sheets by stapling, gluing and the like for receiving the sheet of sufficient length to cover the whole structure.

When the design is covered with insulating material, generally accepted giving the material a more permanent fixing. This can be achieved by various means, such as additional wire, stapling or compacting the joined ends of the walls, covered wrap design with a layer of polymer or metal and/or coating or application of the outer side of the binding agent or the like.

In the EPO application EP-B1-0 004086 described a sheet of mineral fiber pipe insulation. A sheet of mineral fibers consists of several plates connected to each other by means of a connecting means attached to the guide slot plates. The fit is accordance with EP-B1-0 004086 connecting means can be strings, stretched along the length of the sheet, which may have the excess part, outside of the sheet to ensure fixation of the plate with wrap the strings around the sheet and/or binding or tension using free of excess parts of strings.

Because some sheets for the insulation of this type are relatively heavy, typically used thin strings, unfortunately, not able to withstand the weight insulation without wrap around cover design several times and/or without tie-in insulation material, even if they stick to the sheet, as described. In addition, often working, making insulation works, it is necessary to isolate structures that are not readily available, and it would not be appropriate if the worker had wrapped the excess part of the string one or more times around the structure, at the same time holding the insulating material. In particular, it is not reliable when the isolation of large structures.

Further, to ensure sufficient surplus strings for fixing in a variety of situations to include in the partition very long strings. These long dangling strings of a good during transportation and fixing of the sheet. It is also impractical to have such a long, loose strings during production or upconcentration products. However, if there is only a limited surplus length of the string, then the length of the sheet and/or strings, respectively, defines some of the maximum circle that can be effectively covered in the sense of how far the string can get. Naturally, this is not the ideal solution.

When the insulated structures are located in fire-prone environment, it is also often desirable to apply an insulating device that includes significant quantities of flammable components, such as glue and/or strings of cotton or the like, which, however, was proposed in the EPO EP-B1-0004086.

However, one of the main problems known from the prior art occurs when the isolate various designs of non-standard or unusual size. In such cases, you almost always need to manually cut the insulation product to fit to the insulated surface. Such cutting of the sheet leads to the cutting of the free parts of the connecting means, which then requires other means of fixation. Obviously, it is impractical and leads to time and cost increase.

Accordingly, an object of this invention is to overcome the limitations of the prior art and provide insulation products of this type, which mo is et to be easily adjusted in size and/or shape and can be installed and connect with yourself, adjacent sheets, insulated design or the like.

This is achieved through insulation products in accordance with the invention, characterized in that the elongation of the locking means in a first specified direction can effectively be modified by drawing one end of the locking means and that the specified tool is mainly extended in the direction of thickness of the product.

Extension locking means by extrusion, preferably by hand, you can get the insulation product without hanging strings or wires which may interfere during the manufacturing, packaging, transportation or installation of the sheet.

The excess part of the fixing means, freely released from the product after extrusion devices can be used in almost any method for securing the connection means on another part, for example, by pulling or binding, wrapping or twisting. In accordance with the invention the locking means is practically inside the product until then, until you need it. Naturally, it is preferable that the end of the locking means substantially performed abroad products to allow the worker to grab it and pull.

Another great advantage in accordance with the invention it is, that the insulation product can be cut to any size or shape without worrying about whether the locking means after cutting to have the specified length to ensure fixation. Unused additional length locking means makes it possible to extend the tool even after cutting the sheet to a desired length.

The extra length in terms of possible or length stock length locking means may be placed within the retainer, means and/or on the sheet in different ways. One of the preferred methods is the use of fixing means in the form of a spiral, which at pulling straightened, at least partially. Other preferred starting form the locking means include a more or less regular shape or formation, such as sawtooth, sine, square and/or other types of cycles, ripple, fold convolutions, for example, in the form of springs. The locking means may be attached to more than one of these forms, not necessarily overlapping.

Preferably, the amplitude of such periodic forms in General was of the order in the 2-300 times more thickness and/or diameter of the locking means, preferably 3-150 and more preferably about 4-50.

If the locking means is made, in particular, in the form of springs or other considerations which has the ability to shrink, at least partially after stretching in the given drawing, it is advantageous to provide such a tool fixing device, for example, hooks, claws and the like, to give the ability to gain a foothold on other objects, such as a corresponding part of another fixing means or on the other end of the same device, thereby further facilitating the process of consolidation. In that case, if the product is equipped with a mesh or grid cell, the fixing means, obviously, can be easily attached to it.

In some cases, it is preferable that the fixing means at some points, at least not directly recorded on the insulation product in such a way that pulling on one end of the fixing means is not meant that the other end of the fixing funds became unavailable, and therefore unusable.

On the other hand, preferably only commit funds to the insulation product to the extent that the product can be cut to almost any shape and/or size without losing the ability to provide a significant lengthening of the locking means. In accordance with this locking means can be attached directly or not directly on the product in the points on a certain item is edocfile - equidistant intervals, for example, interspersed with stitches used in the existing prior art for fastening the cell of the mesh to the walls of mineral fibers, which are disclosed in patent WO 95/27095, and/or the connection can be done in such a way that it could be, if necessary, easily and how disconnected the consumer. The locking means may be directly or not directly attached to the insulating material by gluing or soldering, welding and/or stitches/stitching or the like.

However, attaching the locking means for the insulation product successfully and preferably can be provided essentially by friction or the like inherent in the mind, shape and/or location means with respect to the partition that will be discussed below.

The current level of technology it is known that to obtain insulation composite articles comprising several identical or different layers of insulation and other materials, these products and insulating sheet provided with a layer of foil, for example, aluminum or polymer and/or mesh, for example, in the form of a grid cell that is described in the patent WO 95/27095. In accordance with the invention, the locking means preferably may be located between layers within such composite isol the traditional products. However, it is also preferable to include locking means in one of the layers. The latter is particularly preferred in the case, if there is only one layer, i.e. the layer of insulating material. The locking means may be located anywhere within such layer. As already mentioned, the locking means can take various forms and be located in a variety of ways within the product. However, in the General case, it is preferable that the placement of the locking means has not been performed so that the specified extrusion resulted in compression of the insulation material, in particular, in the thickness direction, as this can lead to the worst insulating properties. This can for example happen if the locking means along the length covers a part of insulating material, for example, the penetration of the layer in the thickness direction in a number of stitches or the like. Therefore, it is preferable that the fixing means is not passed through all the product in the direction of thickness, and, in particular, do not pass through the entire thickness of the insulating layer and, in General, do not form loops around the insulating material. In most cases, it is preferable that means for the most part lengthened in the direction of thickness of the product at 90%, more preferably about or less than 50% and the site is preferably only slightly.

If the insulating material includes a layer of foil or mesh, in particular, it is preferable to arrange the locking means directly under the foil and/or grid, that is, between the touching surfaces of this layer and insulating material.

Positioning the locking means as described, you can restrict and even eliminate the use of funds for the direct connection of the locking means for the insulation product. Normal friction force between the locking means and the surrounding(s) material(s) in most cases, it helps to ensure a strong enough hold the locking means, in particular, when the locking means preferably is extended to its full length and/or width of the product.

Of course, it is also preferred that the magnitude of a possible extension, as well as the ease with which the tool is extended by pulling, was comparable with the strength and/or rigidity of the tool. Given elongation is preferably achieved by manual extrusion without the use of special tools. Preferably, the desired force deformation was 0.5-100 N, more preferably about 5-50 N and most preferably about 7-15 N. A typical value when applying the present invention is about 10 N.

Commonly used fixing sredstvo accordance with the invention has a strength of about 70-700 N/mm 2, preferably about 100-400 and has a hardness of about 70-220·103N/mm2, preferably about 100-150·103N/mm2.

Especially preferred locking means suitable for use in accordance with this invention, provides an elongation of about 20-120% of the tensile strength of around 5-25 H, more preferably 25-75% of the tensile strength of around 7-15 N.

The locking means in accordance with this invention, in principle, may be of any shape, allowing for a secure fit, insulation products. Originally one of the preferred types of fixing means has the basic form of a flat ribbon or strip. When using this tape excessive length exists in the form of folds of the ribbon.

However, it was found that the securing means having the basic shape of the wire, has advantages. This wire may extend along the entire length and/or width and/or thickness of the sheet, or it can be attached directly or not directly in a worksheet from one end, the second end is at least one of the edges/surfaces of the sheet, forming the locking means, which, when stretching can significantly lengthen the edge of the sheet to ensure the fixing of the sheet binding or the like.

When using wires is preferable that the diameter of the wire was set depending on the properties of the sheet so that if wire is not essentially crashed into a wall. Alternatively and/or in addition, between the wire and the insulation material can fit a protective layer. This protective layer should preferably be, for example, polymeric and/or metal foil and/or the grid.

However, when using a grid, such as grid cell, it is preferable to have the retainer(s) wire(s)placed under the net, preferably directly under the specified grid. Alternatively the addition of the locking means in mesh with the binding target funds to specific places can give advantages. Obviously, the latter principle can be used, if using foil with holes.

Problem connecting wire, which cut into the insulating material occurs mainly when the insulating layer consists of fibers, in particular of mineral fibers and/or when connecting the wires are thin.

In accordance with a preferred variant of the invention applied wire from essentially non-combustible material.

In accordance with another preferred variant of the invention, the locking means used of a metal wire or similar material. Most of the metal wires can be easily twisted together, forming so on the second connection. This provides the advantage, so as to ensure the fixing should not tie any complex assemblies. This advantage is achieved even with the use of one hand, which is a big improvement compared with both hands, known from the prior art. When using only one hand to curl, for example, compounds of the ends of the wire, the second hand remains free to maintain the sheet holding the sheet in place, or for other purposes.

An additional advantage of using metal wires as the fixing means is that in some purposes they can at least partially replace the necessary otherwise the cell grid. Unexpectedly, it was found that it is possible to completely replace the cell grid standard reinforced wire products, for example, described in patent WO 95/2795, installing a number of fixing means in accordance with the invention along the length and/or width of the product. In this case, the locking means is preferably located at a distance of 5-50 cm between them, preferably about 10-25 cm and most preferably about 10 see, Then, that preferably when replacing cell mesh, wire placed in both directions, as the length and width of the product, then eats is preferably in two, more or less perpendicular directions, in particular, it is preferable to twist the wire, or freely tie them together using a thin threads or the like so that in combination they were essentially a self-sustaining network. In this case, the benefits of the education network are provided even when the individual fixing means is not limited to welding or other method rigid attachment to other devices, as it happens, for example, in the case of wires, forming on the choice of the applicable grid cell.

In particular, when isolated horizontally positioned pipe or the like, the prior art well-known problem that when the insulation materials of the existing state of the art have a tendency to slip, that is, the insulating material does not provide a good wrapping. Therefore, the advantage of this invention compared with previous products is that it provides a good solid mounting even on horizontal structures.

Then suddenly there was the possibility, in particular, when the locking means is a metal wire, the application of some well-known tools in a new way, providing, in particular, suitable mounting method insulation products in accordance with the invention Such instruments include “American screwdriver and packing needles.

Also you can use special tools and/or adapters for existing tools, working as tweezers or the like and adapted to capture a video, first one end of the fixing means, and then one end of the second fixing means, or capture both at the same time, and then allows you to easily twist the ends to get a solid connection. Obviously, both ends of the fixing means can be any end of one and the same device, as well as two or more ends can be connected to the specified method.

Such tools are preferably provided with a motor or similar to perform a rotational movement, that is, as do electric drill or screwdriver, and tools preferably are cordless/rechargeable. Alternatively such tools are adapted to provide twisting motion of mechanical devices that have built-in screw with a big step.

Another advantage of using metal wires is that the excess length should not be great, because you don't have to tie knots or wrap. Moreover, thanks to the properties of most metals, it is guaranteed that the protruding excess of the locking means remains in place, even if the insulation product is s is subjected to rough handling. Further, in particular, it is possible to easily adjust the force required to extrude the desired amount of clamping means, by adjusting the composition of the applied metal, the size of the metal used and/or choose a way to store the excess part of the locking means.

The metals used for the fixing means include aluminum, iron, various iron alloys such as steel and/or copper. In particular, it is preferable to use a steel or iron wire because of their strength and price. Further, in the General case, it is preferable to use a metal having good durability as well as corrosion resistance. Corrosion resistance can be achieved by plating, for example, zinc.

The preferred alternative metals for use as the fixing means include polymeric and/or glass wire. In particular, the preferred deformable polymers and/or elastomers, i.e. materials that in themselves are capable of elongation, in particular, without stratification.

Metal wire or other wire can be coated or wrapped with other materials, such as polymers and/or paper. This can increase the diameter of the wire and to prevent the cutting wire in the insulation layer. It is also possible the use of such coatings or wrappers in ka is este sleeve to achieve a telescopic effect, so that the inner core could go outside cover or wrapper.

In accordance with another variant of the invention the locking means disclosed visible color for ease of identification on site. The preferred color is easily distinguished from an insulating material and/or other components of the insulation product. Since the isolation often occurs in places with poor lighting, in particular, it is preferable to use bright or fluorescent colors.

In a particularly preferred embodiment of the present invention uses a metal wire, equipped with a visible colored coating. This way can be saved expensive metal, at the same time provide sufficient flexibility and strength, much greater diameter, and easy visual identification of the locking means.

In accordance with the invention, obviously, you can use different locking means having different properties and marked each corresponding individual color code.

The invention also relates to the use of insulation products in accordance with the invention in order to isolate, in particular the isolation structures of the closed section.

Further, the invention concerns a method of obtaining insulation products having at least one there is actually a flat surface, including a layer of insulating material and an elongated retainer means having a specific length and transmitted at a first distance in a direction essentially parallel to the surface, and this method includes a step of at least partially secure the locking means, at least, not directly to the insulating material, characterized in that the securing means is minimized in such a form that the real length of the tool, at least 5% greater than the first distance, and in this way the locking means through the extrusion may be at least partially stretched to a size greater than the first distance.

Excessive length are usually obtained by the method in accordance with the invention and to the chemical products used in accordance with the invention, 10-50%, preferably 15 to 49%, and more preferably 20-30%. However, if the product must be fixed manually, i.e. by linking, tying a knot or manual twisting, preferably, to simplify the process with each end was available, at least 5-15 cm, preferably about 10 cm, the locking means.

It is also possible to provide products of the locking means with a very large excess in length, for example, 50-200%, preferably about 60%, but more preferably 70-90%for partial or complete replacement of the locking means connecting wire, usually used for fastening or stitching together of insulation products from the current level of technology after pre-Assembly of each of them.

When used as a fixing means of metal wires and/or products with similar properties in the manufacture of insulation products in accordance with the invention is preferably formed such wire so as to cause a small voltage potential within the material of the wire. It is preferably made by molding in the form of smooth curves, and not steep curls. Although the sawtooth and/or square waveforms are effective and can be successfully applied in accordance with the invention, particularly preferably using rounded cycles or wavy forms, for example, is close to sinusoidal wavy form.

In accordance with a preferred variant of the method in accordance with the invention, the extendable means can be formed by passing through a number of more or less siteplease gears. Although such treatment is expected sawtooth shape, unexpectedly it was found that the securing funds become relatively rounded wavy shape, almost close to sinusoidal wavy form.

Such advantageous form of locking means may be p is obtained using conventional gears, known from the prior art; good results are easily obtained by selecting the size and number of gears, height, and shape of the tooth, as well as the degree of engagement of the opposing gears depending on the size of the locking means.

For wires, for example, include a metal, in particular, are usually preferred steel wires having a diameter of from about 0.3 to about 1.5 mm, preferably 0.5-1.0 mm, and more preferably about 0.7 mm, with surprisingly good results can be obtained using two gears, geared to such a depth that could be obtained from the above-mentioned excessive length. The preferred gears for use in accordance with the invention are all known gear suitable for the specified bending the locking means. Preferred gear for use with wire sizes indicated above include, in particular, the gear having a diameter of 75-200 mm, preferably about 120 mm, with about 15-30 teeth, preferably about 22 having a height of 5-15 mm, preferably about 10 mm, these gears engage on 3-12 mm, preferably about 5-10 mm

As an alternative and/or in combination with the above method of fixing means can be folded into the set (s) form (s) using, for example, the same Prince who PA, known for sewing machines, linking and/or connecting means to the product. Such a machine can be eccentric mounted device, or even gear with feeding, locking pin means with the grid, even before Assembly of the cell grid and the insulating layer.

In accordance with a preferred variant of the method according to the invention, it is preferable to use the insulating materials based on mineral fibers and to provide any predetermined fixing means at one stage almost continuous production method. This almost continuous method for the production of mainly begins with the formation of a sheet of mineral fibers, known from the prior art, for example, that described in EPO patent EP 0551334, after which the sheet of mineral fibers provided with locking means according to the invention.

For example, this can be done by feeding a continuous sheet from the place of receipt on the conveyor belt through a zone in which the locking means is inserted in the worksheet. The locking means is usually pre-manufactured wire or the like which before use are located on one or more supply reels, however, the locking means can also be made in advance and/or place. This method certainly is about, applicable to virtually any types of insulating materials.

Further, by pre-fixing means may be attached to one or more of the specified forms and/or adequate ability to achieve a specified elongation at pulling. However, it was found that due to the storage of the locking means, preferably in the coils or the like, giving the fixture tool set(Oh) form(s) after it leaves the feed spool just before the introduction of the insulation product is best. In this case, can be achieved more efficient storage of raw materials for the fixing means, for example, a straight steel wire.

Then you can use the same raw material for the locking means having different properties, i.e. giving different forms depending on the particular application and/or, in General, the excessive length of (potential extension) retainer means required for each individual application.

The locking means can be attached to the insulating material in several ways, i.e. by gluing, including, in particular, the use of soldering, the stitching, fastening or the like. The locking means may also not be directly connected with the insulating material, if the calculations product includes other components, allows mounting of the locking means to them.

If the insulation product includes metal and/or welded material, for example, a thermoplastic material, it can be welded to the specified material or attached by soldering.

If the locking means is attached to the insulation product, it is preferable that this be done so that work in the workplace could easily pull the locking means fully or partially, if required. For this purpose, has been found particularly advantageous to attach the locking means to the product by soldering at several points along the locking means or similarly using thin or free threads.

Accordingly, a preferred variant of the method in accordance with the invention is provided by the boundary surface between the retainer means and the insulation product with a quantity cured or fused solder continuously for the specified interface and/or at specific points. Preferably it is carried out in the production area, in which the locking means is inserted into the insulation product.

For the fixing means is not fully passing from one end products on the other, it is preferable that the locking means has been C is krepline hard at the end it does not pull. For a relatively small products is advantageous to provide the rigid grip fastening means relative to the rest of the product, for example, in the middle.

A particularly preferred method of fastening the locking means for the insulation product in accordance with the invention and including any type of coating, attached to the insulating layer, is the placement of the locking means between the facing to each other surfaces of the insulating material and coating. In this case, of course, possible to apply the above mentioned techniques for attaching the securing means to the coating and/or an insulating layer. However, more preferably, the locking means held in place by the friction between the materials.

For insulation products commonly used for insulation from high temperatures common to the sheet of mineral fibers were provided with a coating of cell mesh, attached to the sheet, for example, by fastening. In such cases, preferably in accordance with the invention to use the locking means, for example, one or more steel wire, moulded in the form of any one of the specified forms described herein, and placed under the grid cell, as described above. Unexpectedly it was found that, in the first of ered, provides sufficient retention of the locking means, which ensures that it will remain in place during transport, and, secondly, ensures that when pulling from one end of the locking means will lengthen due to the straightening in the direction of stretching before it is stretched from the product. Hold the locking means can be easily modified for each case by the selection of suitable size and shape of the locking means.

The obvious advantage is almost not directly fixed locking means for the insulation product is that the product can be cut almost any way that does not affect the binding.

Another preferred method of forming the insulation product with a fixing agent, is the inclusion of a locking means in the layer of insulating material. This can be done by entering the locking means in the insulating material in a suitable place, where he, through bending of the insulating material and/or a suitable separation of newly received insulating material is integrated into the insulating material.

Additional variants of the present invention include the possibility of modifying itself, at the option of used cell of the grid or its elements in the same way, topradius above with respect wires. Due to this, the resulting excess length of wire or these elements may be removed by the use, as described, and used for fixing the product on adjacent parts, products or designs. One of the parts, especially suitable for such actions, is edging wire grid cell.

Typical insulation product in accordance with the invention is a Mat having a more or less rectangular in shape, having two main surfaces and 4 lateral surface, that is, two edges and two along its sides. However, the product may have other shapes known in the art insulation products, such as triangular. The plane of the major surfaces are more or less parallel.

The invention further relates to a method of installation of the insulation product by its fixation on the details, the specified product has two main surface and multiple side surfaces, and includes an insulating layer and one or more extendable elements extends in a direction almost parallel to at least one of main surfaces and almost parallel, at least one of the side surfaces, the process involves the following stages:

a) gripping part of the named element on the side,

b) drawing parts for the extension element is thus to extend it beyond the side surface

(C) fixing the product by fixing pull-out parts for details.

In accordance with the invention, the item is prepared for engagement with the element. Such preparation includes having eyelets, holes, wires, edges, clamps or any other means, is able to place the element, i.e. the locking means.

In accordance with a preferred variant of the method according to the invention stage (C) is performed by tying or binding of the pull-out part with a suitable part of the part to which the product must be attached, and/or by wrapping or twisting an extendable part around it. Mostly this detail may be the product itself, adjacent to a similar or identical product, isolated design, or any other suitable connecting part.

In that case, if the product is mounted on the structure of closed cross-section, it is preferable that the method further include the stage of cutting the product to fit around the circumference before installing the product on the specified design.

To facilitate the tying or binding, twisting or wrapping preferably, the element is lengthened to pull at least 5-10 cm abroad insulating layer.

In accordance with the method of installation of insulation the frame of the product according to the present invention, undoubtedly, it is preferable that the product was the same as described above.

The invention also concerns a device for implementing a method of obtaining insulation products in accordance with the invention.

A preferred variant of the device in accordance with the invention includes a means for transporting insulating material comprising a layer 1 of insulating material, means 6 for distribution at least partially elongated fixing means 5, at least one pair of at least partially siteplease gears 8' and 8", the selection guides for passing the locking means between the said gears 8' and 8" and on the choice of the guides 9 to bring the locking means into contact with the insulation product, means for, at least, not directly mounting the locking means to the product.

Particularly preferred variant of the device includes a separate set of gears 8 for each fixing means 5. In this embodiment, particularly preferably using guides for passing the locking means between the gears.

In another preferred embodiment, the gear attach a standardized value of the excess length of the retaining means, which are then partially pulled out before attaching the securing means to the product put the m speed regulation of the transportation of the products in relation to the transportation of the locking means or Vice versa. In this case, the desired excess length of the retaining means can precisely and continuously controlled without changing the sizes of the gears. This method offers a very simple way of obtaining various products in accordance with the invention, in which the excess length of the retaining means is adjustable for specific purposes.

Means for transporting insulating design may be appropriate vehicle for transportation of any kind, for example, conveyor belt and/or wire.

Guides can be any means capable of controlling the position of the fixing means, for example, rollers, bobbins, sliding bearings, lugs and the like.

Means for attaching the securing means to the design may be a nozzle for spraying glue or solder to the surface between the retainer means and design, “sewing machine” for fastening the locking means to the design or the like. If the design and/or locking means are welded materials, the means for fastening may be made in the form of the device, spot welding, or soldering device, or similar.

In case of using a sewing machine for attaching the locking means, the latter may primarily be located along the line of sewing thus, the button sewing thread did zigzags back and forth over fixing agent.

Another preferred method of attaching the securing means to the product is the availability of devices with one or more teeth, which engage with the product and keep them quite attached to it. In this case, does not require any fastening means. This variant of the invention, particularly suitable in the case when the locking means must be mounted directly on an insulating layer of mineral fibers. Most of the products of the mineral fibers are soft enough for some penetration of the surface layer of such teeth and tough enough to hold the fixed locking means.

Undoubtedly, the teeth can be fixed the same way, which is known in the art gear wires. One particularly preferred method of creating the locking means with the teeth, however, is bending the locking means so that the self locking means forms a row of teeth. This is especially useful when the locking means is made in the form of a metal wire. Does not require particularly stringent binding wire to provide sufficient retention when such locking means are directly attached to the insulating walls of mineral fibers. The teeth are oriented preference is sustained fashion in different directions, what is needed to hold the tool in place, as well as to provide sufficient resistance to elongation when pulling. Naturally, the teeth to some extent can preserve the excess length of the tool.

Another particularly preferred method of receiving fixing means for use in accordance with this invention is giving properties elongation at the expense of loops around seams or stitches and loops are preferably 10-70 mm, and more preferably about 30-50 mm in diameter. Loop laid out before sewing needle, then the needle will automatically be placed inside the loop, preferably near the center. Through this preferred variant of the loop will be ravnovesie from each other at 200-700 mm, preferably 300-400 mm and will always be able to provide a more or less fixed elongation (excess length) by pulling regardless of how cut product, that is, if rectified, only the first loop with the pulling end.
