Definitions

  • the invention relates to a method for providing the warp thread ends a fabric tape, of which the weft threads in the area of the warp thread ends with the exception of one that runs at a distance from the remaining fabric edge
  • the weft bundle should be pulled off before the warp ends by changing a subject one with the help of the weft threads of the remaining Weft bundle formed auxiliary compartment one after the other according to the weaving order isolated and on the side of the fabric edge from the auxiliary compartment be pulled out.
  • the projecting ends of the fabric in the longitudinal direction of the fabric tape running warp threads as auxiliary weft threads of both sides woven into auxiliary warp threads, which in the direction of the weft threads of the Fabric tape between the two fabric edges to be joined are provided.
  • the auxiliary weft threads are woven in via a Specialist training facility for the auxiliary warp threads, according to the weaving regulations is controlled. So that the warp thread ends protruding over the fabric edge gripped by grippers and by the respective formed by the auxiliary warp threads Can be pulled through, the warp thread ends must be corresponding of the weaving order are separated one after the other.
  • the separator consists of a blow nozzle, whose blowing air flow detects the individual warp thread ends and one Takeover rapier feeds the isolated warp thread end pneumatically holds and from the formed by the weft threads of the magazine
  • Auxiliary compartment pulls out around the warp thread end provided in this way to a pull-through gripper for weaving into the auxiliary warp threads between the Hand over the seam to be formed.
  • the warp thread ends for the one to be formed between the fabric edges
  • the magazine band is made by hand must again to a strip of fabric in the amount of two to three repeats to be obtained, in one of the seam width between the to be connected Distance depending on fabric edges from the respective fabric edge.
  • the invention is therefore based on the object of a method of the beginning Describe the kind described so that the elaborate handicraft to manufacture of the magazine association can be omitted.
  • the invention solves this problem in that first of all Free weft threads, at least approximately parallel to each other End sections of the warp thread ends are connected to one another by an adhesive seam and that then the one after the other according to the weaving order Warp ends mechanically from those through the wefts of the weft bundle warp thread ends still kept in the weaving order and be kept at a distance before the individual warp ends of the adhesive seam is cut off and pulled out of the auxiliary compartment.
  • the warp thread ends cannot match a magazine band kept in the weaving order of the fabric tape, but at least as far aligned that a separation by a specialist training with few, only possible wefts necessary for adhering to the weaving order becomes.
  • the wefts provided to form an auxiliary compartment therefore have just the task, the warp thread end released when changing the subject mechanically separate from the warp thread end following in the weaving order, without taking the following warp end, which is particularly important in Area of that weft thread is easily possible that before the change of subject to Release of the warp thread end to be separated this warp thread end in the Weaving order holds because after the change of subject this weft thread is the following Warp thread end in the weaving order.
  • the weft threads in the area the warp thread ends therefore do not have the task of securing the weaving order but to keep the warp ends in a certain orientation so that with these weft threads do not have to be formed a fabric strip. It is sufficient rather, pull these few weft threads from the fabric edge and with lateral distance from each other and to the side of the fabric side by side, which does not involve any particular workload because there is no fabric must be formed.
  • the individual warp thread ends must be cut off from the glued seam and pulled out of the auxiliary subject. Because the isolated warp thread ends of the warp thread ends still in the weaving order after the mechanical Separation is kept at a distance, cutting off the offers no problems at individual ends of the warp thread.
  • a device which consists of a shed formation facility for a with a lateral distance from the fabric edge, the warp thread ends in weft bundle adhering to the weaving order, from a separating device to separate the one by one according to the weaving order Change of subject of warp thread end approved and from a takeover gripper for those separated by means of the separating device Warp ends.
  • the separating device can advantageously be between the thread drivers arranged, adjustable in the direction of the weft threads as well as separating wedges that, like the thread carriers, individually controllable and between those released by the specialist training facility and those still kept in the weaving order by the weft threads Warp thread ends are drivable, with the separating device on the side of each other connected end portions of the warp thread ends a cutter assigned to the individual warp thread ends.
  • each warp thread end released by the auxiliary compartment from those still in the Weaving warp ends are separated, taking it due the individual controllability of both the thread drivers and the separating wedges is possible, first the released warp thread end in the area of that Weft thread that is to be separated during the previous change of subject Has released the warp thread end and at the same time the subsequent warp thread end locks to subtract from the warp thread ends still remaining in the weaving order. At the same time, this will at least in sections from those in the web regulations remaining warp thread ends separate warp thread ends in this Spaced area by a separating wedge that separated between the Warp thread end and the other warp thread ends can be driven.
  • the through the gap caused by a separating wedge between the isolated end of the warp thread and the rest of the warp thread ends allows the neighboring ones to be driven in Separating wedges assigned to weft threads in this gap, which thus starts out of the weft thread that releases the respective warp thread end gradually towards the two sides of the auxiliary compartment through the one after the other Separating wedges expanded so that the isolated from the other warp ends by the separating wedges spaced warp ends on the Cut the side of the adhesive seam from this and on the other side of the Auxiliary compartment pulled out of the auxiliary compartment with the aid of a conventional gripper and turned on a weaving device can be passed on to produce a Connection seam between the fabric edges on both sides warp thread ends woven into an auxiliary chain and serving as auxiliary weft threads is provided.
  • the specialist training facility for manufacturing the for warp thread separation provided auxiliary compartment can weft threads in a conventional manner in eyelets take up.
  • there are particularly simple design relationships if the shed formation guide tubes parallel to each other for the weft threads, so that the isolated end of the warp thread unimpeded through the weft threads between the guide tubes from the remaining ones Warp thread ends can be pulled off, and with small travel for the guide tubes.
  • the thread drivers are different for the warp thread ends to be separated can be trained, there are particularly simple design relationships, when the thread drivers out against the warp thread ends protruding brush bristles consist of in the weft longitudinal direction adjustable straps are provided. About these brush bristles successively released warp thread ends from those in the weaving order held warp thread ends moved away, because of the possible use the brushes only in the area of the one following in the weaving order Warp end of the holding weft thread and the subsequent separation of the isolated warp thread through the one after the other in the widening Gap driven separating wedges an undesirable entrainment still in the Weaving end held warp end is simply excluded.
  • Warp ends to ensure the separator can still be in the warp ends held across the warp ends extending guide bracket can be provided, which are kept in the weaving order Guide the warp thread ends between them immediately in front of the cutting device.
  • the weft threads in the area of the end sections must first 4 of the warp thread ends 3 withdrawn and freed from the weft threads End sections 4 are joined together by an adhesive seam 5 before the weft threads remaining between the adhesive seam 5 and the fabric edge 1 are deducted with the exception of a weft bundle 6.
  • the warp thread ends 3 protruding from the fabric edge 1 can then be separated the warp thread ends 3 a connecting seam for making the Fabric tape 2 are made.
  • a Auxiliary chain 7 is provided, in which the warp thread ends projecting beyond the fabric edge 1 3 are woven in as auxiliary weft threads, in a conventional manner Way by shedding the auxiliary chain 7.
  • the end sections 4 of the warp thread ends 3 are sufficient before they are connected by the adhesive seam 5 must be precisely aligned using a brush or comb in order to To keep the warp thread ends 3 in a predetermined orientation is sufficient Binding is not sufficient, the individual warp thread ends 3 in succession to release the web regulations. For this reason, a weft bundle 6 prepare, the wefts 8 drawn off from the fabric edge 1 and in a lateral distance from each other and from the fabric edge 1 become.
  • the number of these weft threads 8 can be used to hold the weaving order required number can be limited. As can be seen from the scheme of Fig. 1 shows, there is a sieve shaft fabric in the embodiment, so that seven weft threads 8 are sufficient to secure the weaving order.
  • the weft threads 8 of the fabric tape 2 prepared in the manner described are drawn into a technical training facility 9, which corresponds to the technical training has up and down movable guide tubes 10. That through the sufach worn 9 conditional auxiliary 11 allows this according to the Weaving order successively releasing the warp thread ends 3.
  • the in the Fig. 2 shown auxiliary compartment 11 gives the foremost according to the weaving order Warp thread end 3a free, but not the warp thread end that follows in the weaving order 3b, so that the foremost warp end 3a of the through the weft threads 8 retained warp thread ends 3 can be separated.
  • This Separation takes place initially with the aid of a thread driver 12 in the area of that Weft 8a, the following warp end due to the weaving order 3b between the adjacent weft threads 8b and 8c against entrainment holds on.
  • the warp end 3a can therefore over the in the longitudinal direction Weft 8 adjustable, the guide tube 10 for the weft 8a associated thread driver 12 from the warp thread end 3b in the direction of the arrow 13 are subtracted to this separation process through a guide tube 10 continue for the weft 8a associated wedge 14, the is driven between the warp thread ends 3a and 3b.
  • the one by driving in The course of the warp thread end 3a of the separating wedge 14 is shown in FIG. 1 indicated by dash-dotted lines.
  • Thread driver 12 in the region of the weft thread 8d can - like the others Thread driver 12 also - advantageously consist of brush bristles 17 on a carrier 18 which is adjustable in the longitudinal direction of the weft threads 8 are.
  • Thread driver 12 also - advantageously consist of brush bristles 17 on a carrier 18 which is adjustable in the longitudinal direction of the weft threads 8 are.
  • the warp thread ends 3 extending guide bracket 20 are assigned to the warp thread ends 3 in the weaving order on the side of the fabric edge 1 between them.
