Definitions

  • the invention relates to a method and an apparatus for producing single-variety Weft thread waste in the fabric production on weaving machines and optionally Reuse the warp material from one with a rotary edge driver produced catch strip, the rotating body of the rotary edge driver guiding the leno threads is preferably reversible in its direction of rotation.
  • EP 0 127 719 A1 is a device for pulling off the auxiliary edge separated from a fabric produced on weaving machines, which is sometimes referred to as a fabric strip or catch strip.
  • the device arranged near the goods take-off roller of a weaving machine has an auxiliary edge pull-off channel equipped with an injector nozzle.
  • the auxiliary edge consisting of warp and weft is pneumatically fed to a waste container by means of the device, without the warp threads and weft threads being sorted in any way from the weaving machine in order to obtain a sorted waste.
  • EP 0 681 044 A1 describes a method for removing waste edges and one Draw-off device for carrying out the method, after which the weaving is known a loom formed between two driven take-off rollers, the form a clamping point for the waste edge, is passed through into a waste container.
  • the waste edge consisting of warp and weft is here made with mechanical means fed to the waste without a separation process to obtain a single-variety Weft material waste and pure warp material waste are carried out from the weaving machine would.
  • a weaving machine is known from DE 297 08 758 U1, on which the edges of a fabric to be produced and the catch strips are realized by so-called rotary edge rotators.
  • the weft threads for forming the catch strip are tied here by means of only two leno threads by means of the rotary edge rotator, so as to form the catch strip or the waste edge.
  • This publication does not provide any information about the further treatment or use of the catch strip separated from the fabric edge.
  • a sort of weft thread waste cannot always be achieved with this rotary edge turner, because especially with low tensile strength yarns, such as cashmere yarns, no cashmere yarn can be used for the leno thread, because this yarn is too weak in its structure. This would result in leno thread breaks, which would then lead to machine downtimes.
  • a wool thread is used as the leno thread, which withstands the stresses in the rotary edging machine in its quality. Such a thread of wool may not contribute to the purity of the safety catch. Such waste is therefore less valuable and unsuitable for reuse in a spinning mill.
  • the invention is therefore based on the object of a method and an apparatus create, with which, firstly, an absolutely pure weft waste from catch strips in the Weaving process can be achieved that is 100% reusable and secondly the leno threads used to form the catch strips as such optionally again as Leno threads can be used.
  • the object is solved by the features of claims 1 and 8.
  • the safety catch is separated from the fabric, the latter is fed to a rotary body which, at least in terms of its control, is connected to the drive of the rotary edge rotator, thereby twisting or unscrewing the full-twist binding of the safety catch.
  • This pure weft thread waste can then be reused by further processing in the spinning mill. In the same way, this applies to the case that synthetic weft threads or synthetic leno threads are involved, which can then be melted down to produce a pure starting material.
  • the figure shows a schematic representation of the device for Generation of pure weft waste when using bobbins as Leno thread supplier.
  • the device on the left-hand side of a fabric 2 that has been produced for producing sorted weft thread waste from catch strips 1 is shown on a weaving machine.
  • the weaving machine itself is not shown here, only the fabric 2, which is produced on the weaving machine and consists of weft threads 3 and warp threads 10, can be seen.
  • rotary weaving machines for the manufacture of firm and visually appealing fabric edges and for the formation of so-called catch strips 1 rotary edge rotators 18 are used, as are known, inter alia, from the aforementioned DE 297 08 758 U1.
  • the solution according to the invention is now based on the fact that the leno threads 4 drawn from leno thread bobbins 12 and used to form a catch strip 1 having a full-turn binding are moved after the catch strip 1 has been separated from the fabric 2 by means of scissors 9 by means of a twisting device 5 such that they move dissolve the full twist bindings 1a and the ends 3a of the weft threads 3 that are released in the process are picked up by a discharge device 6 consisting of a suction pipe 6a and at least one collecting container 6b.
  • the discharge device 6 is equipped with, for example, a rotary table, which carries a plurality of collection containers 6b and which is operated by means of an electromotive drive 6c, according to the weft selection program, assigns the respective collecting container 6b to the arrangement 6a designed as a suction device.
  • a rotary table which carries a plurality of collection containers 6b and which is operated by means of an electromotive drive 6c, according to the weft selection program, assigns the respective collecting container 6b to the arrangement 6a designed as a suction device.
  • the drive 6c is connected via a control line 17 to the weaving machine control 8, in which the weft selection program is stored, in a signal-transmitting manner.
  • the method steps in particular Form a safety catch full-turn binding 1a, detach the safety catch 1 from the Fabric 2 using the scissors 9 and unscrewing the full twist binding 1a using the Unscrewing device 5 is electrically controlled by the sequence control 8.
  • the full-turn bindings 1a can be unscrewed synchronously or asynchronously to their production by the rotary edge-turning device 18. It is important that the number of forward and backward rotations of the rotating bodies 5a and 18a is the same in asynchronous mode of operation and in a mode of operation with reversal of the direction of rotation. This ensures that the full-twist bindings 1a are always released in the area of the suction of the discharge device 6.
  • the full-turn bindings 1a are formed by, for example, an alternating reversal of the direction of rotation of the rotating body 18a of the rotary edge rotator 18, the full-turn bindings 1a must also be unscrewed by controlled reversal of the direction of rotation of the rotating body 5a of the unscrewing device 5.
  • the corresponding control commands are issued by the sequence controller 8 via lines 15 and 16 in a signal-transmitting manner to the rotary edge rotator 18 or the unscrewing device 5.
  • the leno threads 4 used to form the full leno selvedge 1a are passed via a pulling device 7 to a collecting container 14 after the loosening of the full leno bindings 1a.
  • the pull-off device 7 and the collecting container 14 shown as a rotary drive roller 7a and as a pressure roller 7b the leno threads 4 can be wound onto a pair of rotationally driven bobbins arranged on a rotationally driven bobbin and optionally used again as leno threads.
  • the device according to the invention for carrying out the method consists of the previously mentioned sequence control 8, which controls a known rotary edge rotator 18 with a rotating body 18a via the control line 15 to form a catch strip 1 having a fully rotating edge 1a.
  • the rotating body 18a has eyelets 18b through which a leno thread 4 is guided to the catch strip 1 to be formed.
  • the rotational body 18a itself must be reversible in its direction of rotation because the leno threads 4 are withdrawn from the leno bobbins 12 arranged in a fixed manner.
  • the device consists of an existing in linear continuation of the catch bar 1 Device 5 for unscrewing the full-turn binding 1a, the drive 5b being the Device 5 is controlled by the controller 8 via a control line 16.
  • the unscrewing device 5 has a rotationally driven rotary body 5a, the eyelets for Passing the leno threads 4.
  • the rotating body 5a is operatively connected to the drive 5b via a flexible shaft 5c.
  • the removal device 6 for the weft thread ends 3a is arranged in such a way that a provision 6a in the form of a suction pipe follows the weft thread ends 3a the dissolving of the full-twist binding sucks off and conveys into at least one collecting container designed as means 6b.
  • the discharge device 6 can have a plurality of collecting containers 6b mounted on a rotary driven turntable, specifically when, as already explained in the process sequence, the sorted collection of the weft thread ends 3a is based on the control technology in dependence on a weaving machine control of the weaving process, which is not shown separately here Weft selection program is made.
  • a first collecting container will hold all weft ends of a first weft color
  • a second collecting container will hold all weft ends of a second weft color
  • a third collecting container will hold all weft ends of a third weft color.
  • the rotary drive 6c is controlled accordingly by the sequence control 8 via the line 17.
