Definitions

  • the invention relates to a method according to the preamble of claim 1 and a knitting machine according to the preamble of claim 3.
  • the WO 2008/139713 A1 or the EP 2 161 359 A1 describes a circular knitting machine with a striping apparatus having thread changing devices that can alternatively provide two consecutive knitting systems with thread.
  • Circular knitting machines have also become known (EP 1 612 311 B1 ), the stripers with two or more in the knitting direction immediately successive thread changing devices have such that optionally threads can be processed on one and the same knitting system, which are supplied by one and / or other thread changing device.
  • An advantage of this arrangement is that a thread changing device with only a few thread fingers can be attached to each individual knitting system.
  • the width of a yarn changing device is greater than the system width, even if each yarn changing device can only supply three or four yarns.
  • the technical problem of the present invention is to remedy this situation and to provide a striping apparatus with a thread changing device, which can be used more flexibly than before and largely accommodates the needs existing in the manufacture of Ringelmustern needs.
  • the invention is based on the idea of assigning a single yarn changing device two or more knitting instead of reversing two or more yarn changing devices of a single knitting point as before. Accordingly, the threadable with a single yarn changing device threads are distributed to knitting tools that are placed at at least two adjacent knitting points in a thread receiving position. This is z. For example, it is possible to control a yarn changing device provided with six yarn fingers as needed so that three yarn fingers supply the knitting tools with a different yarn at a first knitting point and the remaining three yarn fingers at a second knitting point. Advantages of this measure are that on the one hand thread changing devices can be used, the z. B.
  • the width of a yarn changing device for z. B. six threads is smaller than the total width of two thread changing devices for three threads. This can reduce the system width and increase the number of systems.
