Definitions
- the present invention relates to a method for producing a woven webbing, in particular an automobile safety belt.
- a stiff weft yarn in particular monofilament yarn, is used to produce cross-stiff tapes on needle-punch looms, in particular automobile seat belt tapes.
- This hard weft yarn has the disadvantage that it looks out of the tape at the edges where the weft reverses and thus produces a hard sawtooth selvedge.
- DE 33 45 508 C2 discloses a two-needle technique with a knitting course on the weft exit side, in which a 2: 2 edge is installed.
- PCT / ET / 48285 As shows a single-needle technique with two knitting needles, in which crochet edges are formed on the weft exit side and on the weft entry side.
- a tape should ideally have the following properties: Soft edges should be created when using hard weft material. Both band edges should be 100% eye-catching not only visually, but also in terms of weaving technology. Even at high weft densities, tight thread interlacing should not be created. The weaving process should be simple and therefore user-friendly.
- the object is achieved by a method according to claim 1.
- a ribbon loom with oppositely alternating weft needles is used, with the effect that a ribbon is produced with soft, exactly the same edges.
- Figure 1 shows, highly schematized, the essential components of a ribbon loom necessary for the representation of the invention seen from above.
- FIG. 2 shows, likewise in a highly schematic manner and without taking a scale into account, an example of a tape according to the invention and also highly schematically the integration of the weft reversal points using knitting needles.
- the method according to the invention proceeds, for example, as follows:
- a weft thread 9 is inserted with a weft needle 5 from left to right into a shed formed by warp threads 2 and (in the case described here) knitted on the right band edge by a right knitting needle 6 with a catch thread (not shown). After the weft needle has been returned to the left, the weft thread thus inserted is struck by a reed 3 on the finished fabric 1. The shed changes and the left weft needle with the right knitting needle now remain one machine turn in the rest position.
- the third shot is fired like the first shot.
- the fourth shot is performed like the second shot and so on.
- an additional bracket which is provided with a thread guide eye, is attached to the respective catch thread insert in such a way that a blocking thread drawn through the thread guide eye lies above the weft during the upward movement of the catch thread insert, the catch thread presented from below being first grasped by a knitting needle and crocheted the catch thread.
- the knitting needle which moves further forward, grips the catch thread coming from above when the catch thread insert is lowered, and loops around the catch thread, so that the catch thread is only entwined with the catch thread and is not drawn into the fabric edge, but prevents a possible pulling up of the catch thread.
- the procedure according to the invention is as follows.
- Figure 2 the first two warp threads 11, 15, 11 ', 15' can be seen, which remain binding on the respective weft insertion side 10 and 10 ', i.e. they are always over or always pierced with every shot.
- the weft reversal point moves further away from the band edge.
- the warp threads 11, 11 ', 13 and 13' which are not bound by the weft are bound at the respective weft exit side in such a way that the (soft) catch threads 14 and 14 'interlaced with the weft thread are drawn into the fabric to such an extent that the catch threads replace the missing shot.
- This mode of operation is achieved by increasing the positive catch thread transport and reducing the positive weft thread transport accordingly.
- This method of working means that the weft density in the edge area is only half as high as in the base fabric. This fact is compensated for as follows: A shorter weave is chosen for the edge area than the weave in the base fabric, for example base fabric K 2: 2, edge Ll: 1.
- a thicker thread can advantageously be used for the catch thread, for which half the theodore of the weft thread is usually used.
- a belt fabric in particular an automobile safety belt
- a belt fabric is to be produced on needle looms which, even when using hard weft material, has soft and, above all, 100% eye-like binding edges on the right and on the left edge of the belt.
- This leveling of edges is very advantageous for technical straps, especially for car seat belts, which are exposed to constant movement (friction) in the vehicle, because due to the absolute leveling of edges, no one-sided (saber-like) deformation of the strap can occur, and thus the automatic winding of the strap in the vehicle can take place without interference and there is no so-called strapless.
- seat belts are not referred to as the seat belt that does not fit snugly against the body of the passenger, which allows the passenger to be advanced too far in the event of a crash and thereby enormously increases the risk of injury to the passenger.
