Definitions

  • the invention relates to a method for producing core yarn according to the preamble of claim 1, and a device therefor.
  • core yarn When core yarn is formed when forming the yarn, in particular in its stretching to a desired fineness and its solidification, inserted by turning a core thread in a fiber structure and wound by the fibers. This happens so far that the core thread disappears in the fiber structure.
  • the core yarn essentially determines the strength and elongation of the yarn produced, while the fiber structure determines the feel and appearance of the yarn.
  • a core thread can serve, for example, an endless, synthetic thread, while staple fibers made of cotton or wool are usually used as a fiber dressing.
  • a core thread is introduced directly into the pair of output rollers of a drafting system.
  • This thread together with the fiber structure, passes through the fiber-bundling zone between the pair of delivery rollers and a pair of delivery rollers in which the fibers are already applied to the continuous filament by the combination and then twisted together to form a core yarn upon leaving the delivery roller pair.
  • This means that the core thread and the fiber structure are already brought together before the compression device, so that the compression of the fiber structure is disturbed by the core thread.
  • a traversing of the fiber structure to equalize the wear of the rollers is not possible.
  • the DE 103 44 163 describes the production of Corescheinzwirn, wherein the respective fiber structure is supplied rectilinearly supplied to the compacting device.
  • the fiber structure is guided over a compression device that is clearly oriented in the transport direction so that there is no lateral displacement during compaction.
  • the core thread is guided in the same plane in which the fiber strand runs.
  • the fiber structure is supplied separately from the core thread of the compression device with a traversing movement and is preferably combined with the core thread only at the end of the compacting process or thereafter.
  • the fiber structure should be changed before compacting. On the one hand this improves the compaction of the fiber structure, on the other hand it ensures that the fiber structure does not run into the surface of guide rollers, which otherwise can lead to unacceptable wear of the guide rollers. As a result, the life of the guide rollers is significantly increased.
  • the core thread is guided stationary, although the invention should also encompass a traversing of the core thread.
  • the fiber structure is guided approximately parallel next to the core thread in the compacting device and in particular in the compacting zone formed before the compacting device. If the compression zone in a preferred embodiment has a suction slot, the fiber structure is essentially guided over this intake slot and alternated over the width of the intake slot. Preferably, only at the end of the intake slot or after the fiber strand and the core thread are combined with each other.
  • An apparatus for carrying out the method has a compression device with a suction slot.
  • This suction slot has edges or a Raffkante, which extends inclined to the direction of the core thread.
  • the intake slot is curved wedge-shaped and tapered in the direction of the core thread.
  • the inventive method and the corresponding device can be provided not only in a re-creation of spinning machines, but also existing spinning machines can be equipped with the inventive device and operated with the inventive method.
  • a core yarn 1 is used according to Figures 1 and 2 made of a core thread 2 and a fiber strand 3.
  • the core thread 2 is fed via an insertion roller 4 of a compression device which follows in the present embodiment, a drafting or is part of this drafting system. It consists essentially of a roller 5 with an evacuatable interior 6, wherein on a jacket 7 a Kompaktierzone 8 is formed.
  • This Kompaktierzone 8 shows a suction slot 9, which is curved wedge-shaped. That is, it has a decreasing width in the direction x of the core thread 2, wherein a shirring edge 10 is also curved to the core thread 2 out.
  • the compacting zone 8 is delimited by a nip line 11 of an outlet top roller 12 and a nip line 13 of a clamping top roller 14.
  • the outlet top roller 12 which is otherwise partially wrapped by the core thread 2, a pair of rollers 15 and 16, each with a Riemchen Adjust 17 and 18 assigned. Between the corresponding straps 19 and 20, the fiber structure 3 of the compacting zone 8 is supplied.
  • the core thread 2 is drawn as shown by dashed lines via a guide 21 to the fiber structure 2, or directly via a clamping top roller 14th
  • the perforated roller 5 and the inner space 6 are referred to as compression means 24.
  • the core thread 2 is supplied to the compacting zone 8 via the introduction roller 4 and a stationary filament introduction 21, for example, by passing through the gap between the outlet top roller 12 and the roller 5.
  • a stationary filament introduction 21 for example, by passing through the gap between the outlet top roller 12 and the roller 5.
  • Kompaktierzone 8 it runs at the edge of the intake slot 9, where it can reach near the end of the intake slot 9 near its intake.
  • the fiber structure 3 is fed parallel to the core thread 2 of the compacting zone 8, wherein it also passes through the gap between the outlet top roller 12 and roller 5.
  • the corresponding nip line 11 of the fiber structure 3 is located over the wider, incipient region of the intake slot 9 and then passes as a result of the suction and Kompaktier Quant along the gathering edge 10 toward the core thread 2, wherein it towards the end of the intake slot 9 or later with the Core thread 2 united by rotation.
  • the combination is preferably done immediately before the nip line 13. After the nip line 13, the core thread / fiber bandage can still be given a turn, so that the fiber structure wraps around the core thread.
  • the fiber structure 3 is oscillated prior to joining with the core thread 2, which is indicated by the double arrow 22. This ensures that the surface of the rollers 5, 12 and the straps 19 and 20 wear not concentrated, but are worn in a wider range, which increases their life. Furthermore, the separation of the core thread from the fiber strand in the compacting zone 8 does not disturb the compaction of the fiber material.
  • the apparatus for producing coregarn 1 from a core thread 2 and a fiber structure 3, which are connectable to each other by turning the fiber structure 3 around the core thread 2, wherein a compression device with a suction slot 9 an insertion roller 4 for the core thread 2 and a pair of rollers 15, 16th upstream and preferably a further pair of rollers 5, 12 is downstream, is thus characterized in that the suction slot 9 is inclined to the running direction x of the core thread 2, and that a traversing device for the fiber structure 3 is provided.
  • the fiber structure 3 is brought to the core thread 2 during compaction and combines with it only after compaction.
  • the intake slot 9 is inclined to the running direction x of the core thread 2, and a traversing device 22 for the fiber structure 3 is provided.
