Definitions

  • the invention relates to methods for producing a fabric with fabric strips and at least one temporarily existing catch strip on weaving machines according to the preambles of claims 1 and 2. Such methods are known from GB-A-669 196.
  • a rotary edge cutter is provided for producing the fabric strips, which permanently remain on the fabric, and the catch strip, which is intended only to prevent the weft yarn from springing back into the shed and is separated after the weaving process has been completed .
  • the two rotary edge rotators have disc-shaped rotating bodies which are arranged coaxially next to each other at the edges of the resulting fabric web in the region of the shed. The axis of rotation of the rotating body is perpendicular to the direction of the warp threads.
  • the rotary bodies have in their peripheral area thread guide eyelets, through which the leno threads are passed to form the fabric strips or the Fangleisten threads to form the trap bar. It is expressly pointed out in GB-A-669 196 that the two rotary bodies can be operated either with controlled direction of rotation reversal or without reverse rotation. In the first case, the coils, from which the leno and Fangleisten threads are removed, may be arranged stationary; in the second case, it is necessary to store the coils on a rotary holder. In the preambles of claims 1 and 2 of the present application these two cases are taken into account.
  • GB-A-669 196 contains no information about how the drive of the two bodies of revolution should be realized constructively. After the age of this document, however, it can be assumed that the drive is derived mechanically from the main drive of the loom. This must necessarily mean that the two rotary edgebanders operate at a common speed, which is set once in the design of the loom, and that also the phases of the periodic change from forward to reverse rotation can be subsequently changed only with great effort. Furthermore, the possible speed of the conventionally driven rotary edger is not very high, so that they are limited in modern, high-speed running weaving machines.
  • rotary edge knives are already known, which are driven independently of the main drive of the loom by its own electric motor. Such a rotary edge cutter can be individually controlled and programmed. This applies, for example, to certain phases of forward and reverse rotation or to the selective setting of single bonds and bond misfires.
  • the rotary edge twisters according to DE-A-44 05 776 and DE-A-44 05 777 have been proposed for forming the fabric strips or fabric edges on high-speed modern weaving machines and have proven themselves.
  • a further disadvantage is that in the multi-filament crosswheels the Fangleisten threads are mechanically stressed very high, especially by deflections of the threads. It is therefore necessary to use safety catch threads of a tear-resistant material, for example of a synthetic material.
  • the Fangmann then consists of natural weft yarn, while the applied as Vollcarderitati Fangleisten threads made of a synthetic yarn.
  • a further disadvantage is that in the case of an automatic weft breakage repair, which requires reopening (reverse weaving) of the previously closed shed, the catch wedge compartment setting the defective weft thread is not always released. Then, the weft breakage repair can not be performed in the required short time.
  • the invention is therefore based on the object to improve the aforementioned method with and without reversing the rotational body so that the high weaving speeds of modern weaving machines are achieved, at the same time the material used for the catch strips is reduced, the weft threads on both sides of the fabric reliable be held and yet after the separation of the catch strips a high quality, durable fabric strip of beautiful visual effect comes about.
  • catch strips no longer have to be as wide as when using the conventional edge twister or in canvas binding catch strips, also required for the catch strips end portions of the weft threads are shorter and also achieved a material savings in the weft threads.
  • GNeillrvebmaschinen it was possible to save by the new construction about 25mm weft material per shot.
  • the lower mechanical stress of the Fangleisten threads by the present invention used according to the rotary edgers also leads to the fact that the Fangleisten threads in very many cases may consist of the same material as the weft threads, resulting in not only less, but also sorted waste.
  • wool tethers may also be used, while in the manufacture of synthetic fabric, synthetic tuck yarns are used. Since the waste is sorted, all separated catch strips can be fed virtually a workup and reuse, which means a cost savings for the weaving.
  • the base fabric and the fabric strip consist of the much finer warp threads and leno threads; Therefore, the shed and the fabric strip tray should be kept open as long as possible so that warp threads and leno threads are not disoriented or even damaged by the penetration of the weft thread, for example by touching the gripper.
  • the flow .DELTA..alpha Of the rotation body leading the catch strip threads to the rotation body guiding the leno threads allows to fulfill the two opposing requirements, the fabric strip visible after the separation of the catch strips is not only of high quality but also of good optical effect. At the same time prevents the flow ⁇ in the edge formation, the "preliminary work" of the trap bar against the binding point of the shed, as given by the former shorts a better leno thread training.
  • the invention also relates to the apparatus required for carrying out the method, which are specified in claims 3 and 4.
  • the relevant and taken into account in the preambles of claims 3 and 4 prior art is again the GB-A-669 196th
  • the device consists of a first rotary edge cutter 12 and of a second rotary edge cutter 13.
  • the construction, the arrangement and the mode of action of both edge twisters are comprehensively described in DE 44 05 777 C1, so that at this point repetitions are described is waived.
  • Each of the edge twisters 12, 13 has a leno threads 7 or a Fangleisten threads 9 leading rotary body 12a with not visible here Fadens Entrysösen 12b and a rotating body 13a with Fangleisten threads leading Fadenationsscher 13b.
  • Both edge twisters 12, 13 are rotatably drivable with one rotary drive 14 in each case.
  • the rotary actuators 14 are driven by a drive control 15.
  • the means for forming the shed 6 are not shown here, because generally known.
  • At least one weft thread 4 is entered from the entry side of the shed 6 to the arrival or withdrawal side by means of pneumatic or mechanical entry members.
  • the here in the subjects 6, 8, 10 registered weft thread 4 is to hit by the reed 27 to the stop edge 1a, 2a of the fabric 1 and the fabric strip 2 and by the Hilfswebblatt 28 to the stop edge 3a of the catch strip 3 and to Bonding by the shedding organs on the side of the shed 6 held by the weft insertion member 26.
  • the rotary bodies 12a, 13a are replaced by a multiplicity of successive half-turns, e.g. in which one direction of rotation, and preferably by the same multiplicity of successive half-turns in the other direction of rotation, form both the fabric strip 2 and the catch strips 3 as a fixed full-turn edge.
  • the device shown here is arranged on the right side in the loom rotary edge twister 12 and 13; another device of the same construction is arranged on the left side in the weaving machine, as shown for example in FIGS. 4 and 5.
  • At least one holding or stretching device 29, 30 is provided on both sides of the fabric 1.
  • a fabric or cutting lane 16 is formed between the fabric strip 2 and the catch strip 3, see also Figure 4, in which a separator 17 engages and the catch strip at the appropriate time of the fabric. 1 separates.
  • each rotary edge twister 12,13 of the device is equipped with its own rotary drive 14, it is possible, each rotary edge twister 12, 13 individually, especially with regard to the reversal of the direction of rotation and the time for setting the weft threads 4 to form the exhaust side fishing line 3, to control.
  • the catch strip threads 9 for the catch strip 3 are, like the leno threads 7 for the fabric strip 2, withdrawn from holders 19 and 18 arranged on coils 21 and 20, wherein the holders 18,19 are mounted stationary.
  • the coils 20, 21 are arranged on a, not shown, rotationally driven coil holder.
  • a rotary-driven bobbin holder is required, first, to prevent any mutual wraps of the leno threads 7 and, secondly, no mutual wraps of the suture strip threads 9 on the path between the rotary bodies 12a, 13a and the coils 20, 21.
  • the device consists of a first rotary edge cutter 12 and a second rotary edge cutter 13.
  • the construction, arrangement and mode of action of both edge twisters are disclosed in DE 44 05 776 C1. It is essential here that both rotational bodies 12a, 13a are the rotors of an electromotive actuator.
  • both edge twisters form a structural unit which is received by a carrying device 22.
  • each edge twister 12,13 is individually controlled and operated in accordance with the shedding.
  • the support device 22 as a whole can be connected via the elongated holes 22d by corresponding machine elements with the weaving machine and positioned in the direction of the double arrow 32.
  • At least a second and third component 22b, 22c is connected to the first component 22a.
  • the third component 22 c is arranged in a plane alone in the direction of the double arrow 33 about a vertical axis 23 pivotally.
  • the combined to a structural unit rotary edge twister 12, 13 are connected to the third component 22c such that the unit along the center axis 24 of the component 22c slidably and about this central axis 24 is pivotable.
  • FIG. 3 shows two rotational bodies 12a, 13a which can be rotated about the center axis 25 with thread guiding eyelets 12b, 13b.
  • the rotary bodies 12a, 13a are formed according to the device according to FIG. 1 or 2.
  • the catch strip pocket 10 sets the weft thread 4 by a few degrees of rotation ⁇ in front of the fabric strip pocket 8.
  • the rotation of the rotation body 13b leads the rotation of the rotation body 12b both in the flow according to arrow 34 and after reversal of direction in the return according to arrow 35 ahead.
  • the degree of anticipatory rotation i. the amount ⁇ , is freely programmable in the drive control 15.
  • Figure 4 shows an entry side of the shed 6 arranged device with different rotary actuators. While to form the fabric strip 2 a first rotary edge cutter 12 is provided with integral rotary drive, so the rotary body 12a is the rotor of an electric motor actuator, the catch strip 3 is formed by means of a foreign-driven rotary body 13a (rotary drive 14).
  • the drives of the two edge twisters 12, 13 are controlled by a drive control 15.
  • a drive control 15 On the entry side of the shed 6, analogously to the arrival or withdrawal side of the shed 6, the ends of the set weft threads 4 are preferably held pneumatically stretched by a holding or stretching device 30 to the inlet into a spreading device, not shown.
  • FIG. 5 shows a device as already shown in FIG.
  • the ratio of the number of reversals of rotation of the rotary bodies 12a, 13a per section of fabric 31 is different from one, that is. not after each weft insertion is a reversal of the direction of rotation of the rotary body 12a, 13a.
  • the ratio of the reversals of rotation of a device consisting of two rotary edge twisters 12, 13 for forming a fabric strip 2 and a catch strip 3 can be varied as desired for each fabric section 31, or that the variation can be freely programmed.
  • Figure 6 shows Fangleisten threads 9, which form the ends of the weft threads 4 by means of Vollwooderabitatien to a catch strip 3 by rotation of the rotating body 13a in one direction.
  • the catch strip 3 as well as in the fabric strip 2, the point of reversal of the direction of rotation is not visually recognizable. In the present example, therefore, it is not shown that a reversal of the rotational direction of the rotational body 13a has been carried out.
  • FIG. 7 shows the leno threads 7, which in one direction form the ends of the weft threads 4 by means of rotation of the rotation body 12a into a fabric strip 2 by means of full-turn ties. Due to the free programming of the rotary edge twister 12, 13, taping variants for the weft threads 4 are conceivable, such as e.g. so-called binding misfires that are equally feasible in the fabric strip 2 and 3 in the catch bar.
  • the technology known per se for producing a full-turn fabric strip 2 can be used without restrictions for producing a temporary catch strip 3. It can further be seen that by the combination of two rotary edge twisters 12, 13 into one structural unit and using the full-turn technology, in addition to material savings for forming the catch strips 3, material savings per weft thread 4 can be achieved.
  • the saving in weft material is made possible by the fact that, in particular on rapier weaving machines, the thread-indicating units and the weft scissors 17 can be positioned closer to the reed 27 by the reduced width of a conventionally produced catching strip 3. Further, it is thereby possible to set the start position of the weft insertion members (donor and taker grippers) closer to the reed 27.
