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 having to undergo 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 on leno bobbins, from which the leno threads are drawn according to the prior art be waived.
  • the objects are solved by the features of claims 1 and 8. Thereafter, after the catch strip has been separated from the fabric, the leno threads of the catch strip are fed to a rotary body which, at least with regard to its actuation, is synchronized with the drive of the rotary edge rotator, thereby twisting or unscrewing the full-turn binding of the catch strip.
  • the figure shows a schematic representation of the device for Generation of pure weft thread waste when using continuous leno threads.
  • 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 as such is not shown here, the fabric 2, which is produced on the weaving machine and consists of weft threads 3 and warp threads 12, can only be seen in part.
  • fast-running weaving machines are used for the production of firm fabric edges which are solid from the visual impression and for the production of so-called catch strips 1, a rotary edge wrench 5, as described, inter alia, in the aforementioned DE 297 08 758 U1.
  • the method steps in particular of forming a full-turn binding binding 1a, separating the catching strip 1 from the fabric 2 by means of scissors 14 and unscrewing the full-turn binding 1a using the unscrewing device 6 are carried out in an electrically controlled manner by a sequence control 9.
  • the full-turn bindings 1a can be unscrewed synchronously or asynchronously to their manufacture by the rotary edge driver 5. It is important that the number of forward and backward rotations of the rotating bodies 5a and 6a 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 8.
  • the full-turn binding 1a is formed, for example, by alternating reversal of the direction of rotation of the rotating body 5a of the rotary edge rotator 5, then the full-turning bindings 1a must also be unscrewed by controlled reversal of the direction of rotation of the rotating body 6a of the unscrewing device 6.
  • the corresponding control commands are issued by the sequence controller 9 via lines 15 and 16 in a signal-transmitting manner to the rotary edge turner 5 or the unscrewing device 6.
  • the unmixed Collecting the weft thread waste can be included in the sequence control 9, specifically in such a way that the sorting of the weft ends depends on the control technology one of the weaving process in the one not shown separately here Weave control underlying weft selection program made becomes.
  • the device for carrying out the method according to the invention consists of the previously mentioned sequence control 9, which controls a known rotary edge rotator 5 with a rotating body 5a via the control line 5 to form a catch strip 1 having a full-turn edge 1a.
  • the rotational body 5a is reversible in its direction of rotation.
  • the device consists of a device 6, in a linear continuation of the catch strip 1, for unscrewing the full-turn binding 1a, the drive 6b of the device 6 being controlled by the control 9 via a control line 16 in the sense of unscrewing the full-turn binding 1a.
  • the unscrewing device 6 has a rotationally driven rotating body 6a which has means in the form of eyelets for passing the leno threads 4 through.
  • the rotating body 6a is operatively connected to an electromotive drive 6b via a flexible shaft 6c.
  • the removal device 8 for the weft thread ends 3a is arranged in such a way that a provision 8a in the form of a suction pipe follows the weft thread ends 3a sucks the dissolving of the full-twist binding 1a and conveys it into a collecting container designed as a provision 8b.
  • the leno threads 4 pass from a thread guide 7 arranged downstream of the untwisting device 6 to a leno thread pulling device 10 which is formed from a rotationally driven roller 10a and a pressure roller 10b.
  • the leno threads 4 are then returned to the rotary edge turner 5 via suitable deflecting and guiding means 11 and subsequently as separate endless leno threads, optionally via a tensioning tree 17 and through a thread monitor device.
