Description

so far not succeeded in this way a multicolored vividness and geometric shape on conventional, To weave ribbon, which allows with regard to the regular multi-protection jacquard ribbon looms, speed and exactness of his figure; ', with a more- whereby at the same time due to the bobbin change is comparable to woven tape. Downtime reduced to a minimum and in itself

It is known (Swiss patent 5 tightly woven, a regular pattern image on-238 672) that when weaving an unpatterned edge tapes pointing should be achieved.
the basic weft to be completely drawn in by drawing in a draw-in thread carried along with the circular chain, starting from a method of the generic type, this object is stabilized according to the invention. In this case, however, it can easily lead to an imprecise solution that, in addition to the formation of the threads forming the figure, the thread forming the base of the thread opposite the thread also grains into the thread as weft thread, as is the case an unpatterned band basic chain is entered that can be very noticeable in the basic chain. To remedy this working thread, which is known according to the defect (British patent specification of the width of the color figures are distributed and on which 729 779), the basic weft is only tied over a section 15 of the different colored threads and to form the tape by means of draw-in binding and steered on that in addition to the weft used for the remaining bandwidth the weft in the usual basic formation is to be entered by a shooter depending on the abbin-way. In this case, however, the working case that determines the draw-in length, in turn, at short time intervals, has a separate shooter thread for the draw-in bobbin change and thus downtimes. When ao is used, which is created exclusively in the warp direction of this known method on which and is wound around the working thread running from the transition point from the pick-up weft and shooter-tied.

On the one hand, this results in an error from in the area of this intermediate edge as possible, on conventional Schützen-J aquard tape ends Irregularities in the weave are used by looms with ribbons of eight to ten, for example target. Colors and on the other hand still becomes the

Furthermore, it is known (French patent 30 special advantage achieved that the entire text in chain letters 366 760), brought the basic weft of a tape towards the direction, used for the weft multi-colored completely by means of a draw-in binding - thread material is removed from large supply bobbins by using several different colored feeder hoppers, while by means of the shooter only one which is carried next to the basic chain and unified into the fabric by one or more »capture threads« Rifle thread will alternately be carried by the one or 35 who have the task in Kettdere Feed thread is pulled in. In this way the colored threads brought in the direction of the ribbon however, no arbitrary geometrical figures can be drawn in, and those in the finished band are essentially but only ran with different colored horizontal stripes only extending in the direction of the warp thread provided tapes are made, gen

There conventional weaving with direct weft thread but with two shooter threads, and one carried each by "Jen Schützen saved on which one for the basic shot and for the edge shot, some of which are frequent, usually already worked after a few hours. which is why, because of the necessary coil changes, shooters have to change the bobbin Significant downtimes are incurred again. borrowed operator work and a frequent There, too, no way is shown how to condition when the loom is at a standstill.

Once they essentially take that through Finally, a device for producing the draw-in binding introduced into the band of cross-patterned band fabric is known, in which, after tension, so that a hole and distortion type Figure threads supplied by warp threads are achieved with the aid of free tape. They continue to contribute to by a special control device transversely 60 serving savings in the formation of the figures the chain adjustable needles to a reference thread - tuned in the following briefly "figure threads" Brought in place and here by the reason - by making it possible to shoot the figure be tied.

As a result, the take-up of the shooter thread is laid laterally to one of the longitudinal ends of the work threads across the width of the basic chain of the shooter spool. Relatively minor additional devices are simplified by these or their subsequent rearrangement. In addition, these dimensions bring conventional jacquard looms to the advantage that the working threads are always used on any multicolored ribbons and the same place in the jacquard card can be struck, so that the construction or acquisition can be done, whereby the drawing work unnecessary for the special looms for this purpose. individual band patterns can be considerably simplified.
