The technical field

This invention relates to a method of textile tape on the right weft thread (SFR) and the left-hand weft thread (SFL) and shuttleless ribbon-weaving machine.

The level of technology

From patent document DE 2719382 C3 (Berger) there is a method of weaving a single-layer belt tape with a hollow hem on shuttleless ribbon-weaving machine with a single needle for feeding the weft yarn. One of the two single-layer woven edge portions by the tension of the weft yarn is pulled to the border of the middle part for forming a hollow rim.

From the patent document CH 648069 A5 (Berger) is known belt-driven tape, in particular for automotive seat belts, manufactured on shuttleless ribbon-weaving machine. Belt-driven tape has a relatively rigid middle portion and soft edges that are rolled into a hollow hem. To increase the speed of production include two needles for feeding weft threads running simultaneously in parallel to each other, and one needle for feeding the weft yarn Prodavat soft weft thread in a middle portion and two edge portions, and the other needle Prodavat more rigid weft thread only in the middle part and two marginal parts covers only the two outer main thread. Two needles for feeding the weft yarn threaded through two different types of weft yarn in a partially p is lichnye open throat. With one weft yarn, threading through only the middle part, two flat edge portion rolled into a hollow hem. The middle part is hardened to improve performance. The aim was that through the use of two needles for supplying weft yarn to achieve twice the performance compared with single-needle systems. However, increasing the mass and the need for more rapid movements of the auxiliary netupdates with greater amplitude due to the presence of two needles for feeding weft threads allowed to achieve performance significantly smaller than a double.

From patent document DE 3345508 C2 (Ieperband) known belt-driven tape, woven in a single layer. Similarly, also pass through two different threads of weft yarn using two needles for feeding weft threads.

The filling thread from monofilament serves only to strengthen the middle part and cannot be used for convolution flat edge parts.

Such well-known belt-driven tape and methods of their production by today's standards too costly and no longer able to meet for the last time requirements of the automotive industry. In particular, increased the need for belt tapes with comfortable soft boundary parts, while the inner part should be as much the Popper is strong rigidity. In addition, the known device for manufacturing a belt belts too complex and difficult operation.

Disclosure of inventions

Thus, the present invention is to provide a belt tape method and shuttleless ribbon-weaving machine of the type specified above, which avoids the disadvantages of the prior art or at least to minimize them.

This problem is solved by the method according to the invention, namely by way of the textile tape on the right weft thread and a left-hand weft thread, characterized in that the two weft threads simultaneously pass through both sides of the tape in the same shed, lead round round holders duck with the formation of reverse loops of the weft yarn, hold the holders duck essentially to surf bird to the edge of the tape, and up to this point, change the throat does not occur.

As a result of application of the method according to the invention turns out that the two weft threads simultaneously input from the right and left hand threading the weft yarn, almost symmetrical loop straps across the tape, where each of them is held on the opposite side of the individual placed there by the holder of the duck, after which the needle feed the weft yarn disposed on its side, along with filling thread and hold it in tension up until the bar h will beat again laid weft thread to the already woven tape material, moreover, the weft yarn, which up to this point held by the holders duck, nailed and fixed previous change of the pharynx.

In this embodiment, the tape preferably is made without any need to use a clamp or chain U. needles, tongue and grooved needle. It also does not require a clutch or weave weft threads. The need for such weaving devices, standard for the more sophisticated tools in the prior art, is eliminated when applying the method according to the invention. Required only for holders of a duck, which, for example, associated with the normal control mechanisms of the needle holder.

Another preferred variant of the method according to the invention for textile belt tape with the inner part, preferably soft right edge part and preferably soft left edge part, is characterized by the following continuously repeating the first sequence of steps:

AG) pass right weft thread from the right side of the ribbon on the right edge part and the inner part by means of the right needle for feeding the weft yarn,

al) threaded through the left weft thread on the left side of the ribbon in the left outer part and the inner part through the left needle to feed the weft yarn simultaneously with step ar),

br) keep right weft thread in the field per the stroke from the inner part to the left of the edge part of the through the left holder duck,

bl) hold the left weft thread in the transition region from the inner part to the right of the edge part of the through the left holder duck simultaneously with step br),

SG) capture the right weft thread left holder duck and return back left holder duck to the edge of the tape,

CL) grasp the left weft thread right holder duck and return back right holder duck to the edge of the tape simultaneously with the step SG),

dr) return back the right needle for supplying weft yarn to the right side of the ribbon,

dl) to draw back the left needle to feed the weft yarn to the left side of the tape simultaneously with step dr),

e) remove loop weft yarn formed in the previous step, with both holders duck bird towards the edge of the tape and send both holders duck in the direction from the edge of the tape,

f) carry out the surf bird both weft threads.

The method has the advantage that the two guides the weft yarn needle for feeding filling threads, input from the right and left hand threading, respectively, simultaneously and almost symmetrically pass across the tape weft threads, each of which is on the opposite side of the transition between the inner part and the edge part is kept placed there by the holder of the duck, then the needle for feeding weft thread return to its sides is, capturing the weft yarn and bringing them in tension, and the weft yarn are held in tension, while the reeds will not beat again laid weft thread to the already woven tape material, while the weft yarn, which up to this point are held by holders duck, nailed and fixed subsequent replacement of the pharynx.

As a result of application of a variant of the method according to the invention both the weft yarn located in the inner part, and only one weft thread in each case present in the outer part, the corresponding side of the threading of this weft yarn. This makes the advantage that each regional area is occupied by only one weft thread and is therefore softer, while in the inner part of both the weft yarn tell her greater transverse rigidity due to the double amount of material in comparison with boundary parts.

The following preferred improvement of the method of the textile belt belt, right and left weft threads which are hybrid yarns, characterized in that after the weaving process implemented such a step as thermal fixing belt tape. Here as weft threads used hybrid thread that occurring after textile thermal fixation is converted into monopolarity structure is attached to the belt-driven tape in accordance with the invention, an increased transverse rigidity, attainable due to the properties of the monofilament, without using real monofilaments.

Hybrid threads are threads which consist of materials with different melting points. They are known from the prior art. The advantage of this is that after using hybrid yarns such as weft threads in the weaving process, as proposed here, it is possible curing of hybrid fibers with the transition in monopolarity condition, if they are subjected to the process of thermal fixation after textile. The components of the hybrid fibers having a low melting point, melt, closing up the components with a higher melting point in the structure, such monopolarity structures, achieving greater flexibility, shear strength and, as they say in relation to the belt strips, the transverse elasticity of the tape.

Another preferred variant of the method according to the invention is that in addition to left needle to feed the weft yarn used incremental left needle to feed the weft yarn, which serves for holding the weft yarn of the monofilament, which is served in the transition region between the left edge part and the inner part, whereby the weft thread from monofilament, in addition to the weft threads, derived the holders duck with two sides, so as a result of additional weft thread from monofilament woven only in the inner part. The method is characterized by the following additional steps:

az) threading the weft thread from monofilament, preferably submitted in the transition region from the inner part to the left of the edge part, left to right up to the transition region from the inner part to the right of the edge part by the extension of the left needle to feed the weft yarn simultaneously with step ar),

bz) hold the weft thread of the monofilament in the transition region from the inner part to the right of the edge part by the right holder duck simultaneously with step br),

cz) capture the weft thread from monofilament right holder duck and return back right holder duck to the edge of the tape simultaneously with the step SG),

dz) return back extension left needle to feed the weft yarn simultaneously with step dr).

Capture, release, and surf the weft threads of monofilament happen the same way in relation already described weft threads. For this purpose, as will be explained in the description below, incremental needle for feeding weft threads.

According to the invention additionally introduced into the inner part of the extension weft thread from monofilament provides the advantage that the belt strip in the inner part of realitaet increased transverse rigidity, at the same time, the regional part, as it should remain soft.

Further preferred improvement of the method of the textile tape in accordance with the invention is characterized by the following second sequence of steps, optionally interleaved with the first sequence of steps for forming, if desired, loops Picot on the outer edges of the tape:

arg) pass right weft thread from the right side of the tape over the whole width of the ribbon over the left side of the tape through the right needle for feeding the weft yarn,

l) threaded through the left weft thread from the left side of the tape over the whole width of the tape for the right side of the ribbon through the left needle to feed the weft yarn simultaneously with step arg),

bpr) keep right weft thread outside of the tape near the left edge portion through the second left holder duck and form a loop weft yarn,

bpl) hold the left weft thread outside of the tape around the right edge portion through the second right holder duck and form a loop weft yarn, simultaneously with step bpr),

dr) return back the right needle for supplying weft yarn to the right side of the ribbon,

dl) to draw back the left needle to feed the weft yarn to the left side of the tape simultaneously with step dr),

EP) is removed educated on the steps bpr) and bpl) loops of the weft yarn, sobeih second holders duck,

f) carry out the surf bird both weft threads.

Thus, it becomes possible to produce tapes with protruding beyond the edge placed in any order weft loops or the so-called loops Pico. This is especially interesting in the production of ribbons and braid, especially for the garment industry. The same applies to the next preferred option improving method according to the invention, characterized in that the applied elastic core thread.

For the preferred alternative refinements of the method according to the invention as weft threads use multifilament yarn, which provide a soft border. Generally, as the main thread in belt belts seat belts are also used multifilament yarn. Thanks in marginal areas preferably obtained the desired soft border.

In another preferred embodiment, the improved method according to the invention uses an elastic warp threads. Because of this, using the new method can also produce elastic tape for garment production.

Along with this problem is solved also shuttleless ribbon-weaving machine, which is equipped with the right needle for feeding weft threads and the left needle to feed the weft yarn, made possible with the TEW simultaneous management the right and left holders duck, serving to hold and release the left and right weft threads, respectively, and also performed in the possibility of functioning, coordinated among themselves, in particular, with the ability to operate simultaneously with each other, also specified the machine is equipped with a bird.

In the following a preferred embodiment of the invention shuttleless ribbon-weaving machine, characterized in that the holders duck fixed on the machine and that Berd elastic image attached and removing the retaining wire, preferably oriented toward the edge of the tape, which are designed to ensure that before changing the throat and before you surf to remove the loop weft yarn loosening the hooks holders duck due to the arcuate movement of the needle to feed the weft yarn, with restraints and hold them by pressing to the edge of the Lena to the moment when the bird will beat these loops.

In this embodiment shuttleless ribbon-weaving machine according to the invention can additionally differ in that the holders duck is flexible in the vertical direction, thereby providing easy lifting strained weft threads and facilitating slippage weft threads.

Shuttleless ribbon-weaving machine according to the invention, the call is authorized to implement a method of making a belt in accordance with the invention is much simpler and with less wear and breakages, what is known from the prior art. For soft edges no longer required edging and edging thread. Also, there is no need for them in the desired equipment, known in the field. This greatly simplifies the manufacture of the belt tape in comparison with the known from the prior art methods and devices. When used as a weft yarn, the hybrid yarn after the weaving process to produce process heat fixation. It does not entail additional costs compared to known prior art methods because all belt tapes, even if they are not made from hybrid weft yarns are subjected to a process of thermal fixation to inform the belt the correct tape shrinkage, the correct degree of drawing and the necessary reserve stretching.

Other advantages and characteristics follow from the dependent claims.

The implementation of the invention

Figure 1 shows a belt-driven tape 2, and the right and left sides of the belt drive belts are in the right and left side of the drawing, in accordance with the capital letters R and L, which are enclosed in the circles in figure 1 below. Such a reading is valid for all the discussed desertia.

Belt-driven tape 2 is divided into three parts, the left edge part of the RL, the inner part M and the right edge portion RR. In each of the areas of transition from the left edge to the inner part outer part and the inner part to the right of the edge are part of the so-called holders SRHR (right) and SRHL (left) duck, which in figure 2 and 3 shows the point of attachment indicated by bold black dot. These attachment points are auxiliary points deduction, the functionality which provides the inflection point duck, opposite side of the weft threading, located within the belt material belt according to the invention, and therefore "lost". Outside each of these points deduction is only a soft fringe, which shows only one weft thread.

Shown in figure 1 to the position shown extended into the mouth about a third needle SNL and SNR for feeding the weft yarn, while figure 2 shows already the end position of the needle for feeding filling threads in position complete. In turn, figure 3 shows the opposite situation where the needle SNL and SNR for feeding filling threads to the maximum laid back, and the inflection point duck at the edge of the inner part formed due to the operation of the holder duck. Figure 3 also shows already advanced closer to the area of threading the reed WB, which is but the next step is moving to a newly laid weft threads, as indicated by the arrow, to be nailed to the already woven material, depicted below the hatch. The owners duck for a short time, cease to perform its function, while with them, so to speak, removed designated break the duck. In the drawings, particularly figure 1, the right side shows as an example the holder SRHR duck, which has the shape of a tooth of the saw. In figure 1 both the weft thread SFR and SFL shown in cross section in the form of points, shortly before they result in movement of the needle to feed the weft yarn will be shifted to the holder SRHR duck came into the position shown in figure 2 (right side). Figure 3 (right side) shows the state of the holder SRHR weft when the weft yarn taken from and through the action Byrd nailed to the material.

In accordance with the invention, a method of manufacturing a belt tape with the interior of M, soft right edge part RR soft left edge part of the RL, with right-hand weft thread SFR and the left-hand weft thread SFL is performed in accordance with the following continuously repeated sequence of steps:

AG) pass right weft thread SFR on the right side of the ribbon in the right edge portion RR and in the inner part by means of the right needle SNR for feeding the weft yarn,

al) threaded through the left weft thread SFL on the left side of the ribbon in the left-hand edge portion and into the inner h is here M through the left needle SNL for feeding the weft yarn simultaneously with step AG),

br) keep right weft thread SFR in the transition region from the inner part of M to the left of the edge part of the LR through the left holder SRHL duck,

bl) hold the left weft thread SFL in the transition region from the inner part of m to the right of the edge portion RR by the right holder SRHR duck simultaneously with step br),

SG) capture the right weft thread SFR left holder SRHL duck and return back the left carrier SRHL duck in the region of the edge VA tapes

CL) grasp the left weft thread SFL right holder SRHR duck and return back the left carrier SRHR duck in the region of the edge WA of the tape simultaneously with the step SG),

dr) return back the right needle SNR for supplying weft yarn to the right side of the ribbon,

dl) to draw back the left needle SNL for supplying weft yarn to the left side of the tape simultaneously with step dr),

e) remove loop weft yarn formed in the previous step, with both holders SRHL, SRHR duck bird WB in the direction of the edge of the VA tape and send both holders SRHL, SRHR duck in the direction from the edge of the VA tapes

f) carry out the surf bird WB both weft thread SFR, SFL.

On the steps of the SG)to (e) holders SRHL, SRHR move forward and backward through a small arc. When moving forward from the edge of the tape - filling thread, promoted needles for feeding filling threads, slide over the beveled face upwards spikes hooks the gaps hooks holders duck. When moving in the opposite direction of the holders SRHL, SRHR move back. Needle SNL, SNR for feeding weft threads go back. Loop SFS weft threads still hanging on hooks. After closing of the throat reed WB goes forward, removing the loops of weft threads and feeding them to the edge of the tape (see also Fig.1-6).

If the interior of M is strongly reduced in width so that it represents only a narrow strip, and at the same time greatly increase the marginal region RR, RL, in comparison with the described prior to this tape makes it a completely different looking tape, the inner part which looks like a thick jumper. To align a possible emerging tension, these parts can weave various ways, for example with a plain weave 1/1 on the edges and weave type "Panama" 2/2 in the inner part. Such tape can advantageously very economical to produce, even with a large width.

As the person skilled in the art know, how does shuttleless ribbon-weaving machine, the following description is omitted details. The main components of a belt-driven tape 2 according to the invention, the threads KF fundamentals and weft thread SFR and SFL, it is easy to recognize.

Figs.4-6 presents the sequence of steps, shown in figure 1-3, with the additional circumstance that shown here, the method and equipment the study additionally shows incremental needle SNZ for feeding weft threads of monofilament, shown to distinguish the hatch.

Figure 6, in particular, specifies both points of inflection duck, SUL on the left side and SUR on the right side, which appear as a result of holders of SRHR and SRHL duck. Figure 5 in the transition region from the inner part to the left of the edge part on the border ready woven material shows a point ZZ serving as sample feed added thread SFZ through galeva healds or similar device. If you follow the steps of the second variant of the method of the textile according to the invention with the use of incremental needle for supplying additional weft threads figs.4-6, figure 4 shows the position of the needle to feed the weft yarn, approximately one-third nominated for Zev. Figure 5 shows the position of the needle to feed the weft yarn after complete passage through the mouth in the position of maximum extension/end position. Figure 6, in turn, shows the opposite position of maximum excretion back of the throat needles for feeding the weft yarn, and the reed WB is already in motion in the direction of the depicted arrow next to the finished fabric, or in front of her weft threads, which are nailed to the already prepared material. On the next step bar again moves away from the edge of the tape, and threading the weft threads again starts from the beginning, so that Polo is giving again becomes, as shown in figure 4, etc. In a preferred embodiment, the boundary part of the RL and RR have a width of only 4 to 8 of the main thread, so the extra thread from the outside, i.e. from the edges of the belt tape is not visible.

In a preferred variant of the method according to the invention it contains the following additional steps:

az) threading the weft thread SFZ from monofilament, preferably submitted in the transition region from the inner part of M to the left of the edge part of the RL, left to right up to the transition region from the inner part of m to the right of the edge portion RR by extension the left needle SNZ for feeding the weft yarn simultaneously with step AG),

bz) hold the weft thread SFZ of the monofilament in the transition region from the inner part of m to the right of the edge portion RR by the right holder SRHR duck simultaneously with step br),

cz) capture the weft thread SFZ from monofilament right holder SRHR duck and return back right holder SRHR duck almost to the edge of the VA tape simultaneously with the step SG),

dz) return back extension left needle SNZ for feeding the weft yarn simultaneously with step dr).

Of course, instead of the variant described here, the device and method according to the invention with the left extension needle SNZ for feeding weft threads or parallel to it is possible a similar option with the right extension needle for feeding the weft yarn or although the authorized use. Then get a mirror, or symmetric situation.

In the preferred case, if the shed is large enough space, you can apply a variant with two additional needles for feeding weft threads left and right.

In the described ways holders SRHL SRHR duck move forward and backward through a small arc. As they move forward from the edge of the tape is held by the needle weft yarn slides over the beveled face upwards spikes hooks down into the gaps hooks (see drawings).

7 very schematically, as an example, shows how the belt tape 2 opens at the edge of the VA tapes formed in the main thread KF Zev I-n-permanently attached to the machine curved in the shape of a hook needle, holder here SRH duck, is located next to the edge of the BA ribbon. Reed WB only starts to move in the direction of arrow ZBA to using removing and retaining wires FSDr to cause the weft yarn in SF specified on Fig position immediately before the edge of the VA Byrd, and removing and retaining wire FSDr shown in Fig position Byrd WB relate to the weft threads of SF. On the further way Byrd, moving in the direction of arrow ZBA on Fig, they elastically thibaudia, turning into shown by the dotted line position FSDr', and thus remove the weft yarn SF with hook N SRH duck, when the bird reaches the weft thread to the edge of the VA tape (i.e. simultaneously).

Figure 9 describes here the position shown in greatly enlarged form, and shows only the border belt belt according to the invention with an improved design of the present invention. Already woven belt tape 2 can be seen in the lower part of figure 9. Border is presented in the form of a right edge portion RR. Clear the reed WB, support, and removing the retaining wire FSDr, pictured here partly in section, refer draped over the hook H of the holder SRH weft loops SFS weft yarn formed by the weft thread SF, to the edge of the BA ribbon. When this arrow ZBA shows just completed the movement Byrd.

Reed WB shows schematically, in a front view, figure 10, the corresponding mean from left to right 7. You can clearly see the location of the photographer and the retaining wires FSDr. You should pay attention to the fact that figures 9 and 10 show only fragments of the right edge part of the belt tape, and the scale of figure 9 and figure 10 are not comparable with each other.

Figure 11 is very schematically shows a top view of the tape 4, with both sides provided on the edges of Pico or loops 6 Pico. Figure 11 observed passing in the direction of the main thread, as indicated by the arrow K, the region R, which in the detailed view Fig helps detail the write holding the weft yarn with the right needle feed the weft yarn in this area. Holders duck, whose function and location have been previously described in detail, are described in figure 11 and 12 example transversely relative to the belt width of the tape. Holder duck in position And also functions as a holder for a duck in the previously described examples, namely in the framework of both edges of the ribbon, and used for holding held-to-left using the right needle (not shown) weft thread SFR, which result in position And forms a loop weft yarns located within the ribbon. Compared with the previously described variants run the tape under 11 and 12 there is a second holder SRHL2 thread in position C. It holds (right) weft thread SFR conducted not shown here (right) needle for feeding weft thread until the needle to feed the weft yarn will not go away from the throat right back in the original position and while not shown here, the reed WB prior to closing of the throat will not move to the edge of the tape and thereby lock loop PS weft yarn for Pico in position, i.e. speaking for the left edge of the tape 4.

The loop 6 Pico on the right hem tape is described above for the left edges of the tape.

It should be emphasized that Fig to simplify the consideration is not shown at the same time threading the left the left weft thread SFL. In the depicted qualitatively configuration weft thread SFR in what is accepted as compressed in the direction of the base, so she schematically includes only the region R along the length of the warp, which is shown figure 11. Then the result of accumulation of numerous superimposed on each other or parallel to each other loops of the weft threads form loops 6 Pico or toothed rim 8, respectively.

On Fig schematically shown both holders duck used in different versions according to 11 and Fig, namely in the position - holder SRHL duck in position In the holder SRHL2 duck, outside woven tape 4. Holders duck moved in accordance with the arrows VZ from the edge of the BA ribbon. In addition, the holder SRHL2 duck operated in two positions Y (raised, if Pico is not made) and Z (omitted if made Pico).

If in a preferred embodiment of the invention simultaneously pass through more than one double weft yarn on each side, preferably partially in different mouths, the advantage is the ability to accurately control the movement of the holders of the duck up and down (similar Fig, position: position Y, and Z). It is easier to capture loops of the weft yarn, repeatedly superimposed on each other, the holders of a duck.

On Fig shows a device according to the invention for implementing one embodiment of the method according of the bretania, in which both the weft yarn SFL and SFR are only one needle 28 for feeding the weft yarn (see details on Fig). In the field tip 34 of the needle 28 for feeding the weft yarn has a lug 36, which is served into the mouth of the first weft thread SFL. The second (right-hand) weft thread SFR captured during the removal of pharynx and reverse motion of the needle 28 for feeding the weft yarn by means located at the tip 34 of the needle gripping device 42 with a hook 40 which can be rotated in various fixed positions.

On Fig shown (here with a disproportionate increase in order to simplify the image), the position of the needle 28 for feeding the weft yarn, in which she spent left weft thread SFL into the mouth. When the hook 40 has already passed the right-hand weft thread SFR. On Fig shows the clamp 30, which serves to make now press the weft thread SFR to the trajectory on which the hook 40 passes on the way back needle 28 for feeding the weft yarn in accordance with the arrow RW (figa and 16b). The right hand weft thread SFR is caught by the hook 40 (figa) and shall be sent by the needle 28 for feeding the weft yarn at the left carrier SRHL duck up until the hook 40 at the touch of a stationary stop 32 (Fig, 16b and 16C) and passing over it will not turn, overcoming the resistance of a commercially available needle 28 for feeding the weft yarn of the spring-latch 38, as shown in the example, when asked to Fig, and as a result will not "lose" right-hand weft thread SFR (fig.16b). This is the end of the threading cycle. The next cycle threading begins forward movement of the needle 28 for feeding the weft yarn in the direction of arrow VW according pigs, and at the intersection of the fixed stop 32 (Fig, 16b and 16C) is now in the opposite direction, the hook 40 is returned to its position capture.

Carried out using the device according Fig-16C method according to the invention according to paragraph 23 of the formulas used for textile tape, in particular a belt tape with the inner part (M), soft right edge part (RR) and mild left edge part (RL), differs in that it contains the following continuously repeating sequence of steps:

sal) threaded through the left weft thread SFL on the left side of the ribbon in the left outer part of the RL and the inner portion M by means of a needle 28 for feeding the weft yarn,

sbl) hold the left weft thread SFL in the transition region from the inner part of m to the right of the edge portion RR by the right holder SRHR duck,

sr) capture the right weft thread SFR spectacular device 42,

sar pass right weft thread SFR on the right side of the ribbon in the right edge portion RR and the inner portion M by means of a needle 28 for feeding the weft yarn,

sbr) keep right weft thread SFR in the area of transition from inwardly the portion M to the left of the edge part of RL through the left holder SRHL duck,

scr) capture the right weft thread SFR left holder SRHL duck and return back the left carrier SRHL duck to the edge of the VA tapes

scl) grasp the left weft thread SFL right holder SRHR duck and return back right holder SRHR duck to the edge of the VA tapes, in particular simultaneously with step scr)

se) remove loop weft yarn formed in the previous step, with both holders of SRHR, SRHL duck bird WB towards the edge of the VA tape and send both holders SRHR, SRHL duck in the direction from the edge of the VA tapes

f) carry out the surf bird WB both weft thread SFR, SFL.

It must be emphasized that the method according to the invention as just described can be performed with only one needle for feeding the weft yarn. Along with this there are alternatives, for example, with two double needles for feeding the weft yarn, the same or different length, as well as the introduction of other holders duck and all sorts of combinations. The specialist should be clear that by means of the method according to the invention can be produced, all known from the prior art types of edges.

Summing up, it is necessary to emphasize once again that thanks to the invention previously excluded constantly required edging and edging threads, as well as the necessary equipment. Thanks to the invention is obtained tape, thinner compared urovnem equipment, what, in particular, with the soft border, is of significant progress in the area of comfort in the vehicle. In addition, the manufacture of the tape according to the invention due to the elimination of some of the production stages and details of appropriate equipment becomes cheaper, than is possible in the prior art.

In addition, an advantage of the present invention is that significantly decreases the tension of the weft threads, and thus, significantly reduced wear, the frequency of breaks and the number of inflection points of the weft threads. Unreliable hook needles required based on the level of technology, and related gaps yarn now advantageously eliminated with this invention.
