Definitions

  • the invention relates to a single or double-sided circular knitting machine with a cylinder equipped with cylinder needles and / or one with
  • Thread selection devices can be used for pattern production
  • Needed threads are fed to the needles of the knitting machine.
  • knitted fabrics with striped patterns or mattress coverings can be produced with three-dimensional structural patterns and / or with patterns produced by colored threads or effect yarns.
  • mattresses only needed selectively in a few places in the knitted fabric. This applies even more if only individual logos or picture motifs are to be knitted in (intarsia pattern). The needed
  • Visible side of the knitted fabric should not be visible on the back of the knitted fabric and selectively knitted, which, for example is described in EP 1 975 294 AI. This on the back
  • mottled threads represent an unnecessary consumption of material.
  • threads can only turn around and only on
  • the present invention is therefore based on the object, a
  • Pattern production can be further minimized.
  • the task is solved by a one or two-sided
  • Circular knitting machine with a cylinder equipped with cylinder needles and / or with Rippnadeln fitted dial for producing single or double-surface knitted webs, the at least one
  • Has thread selection device and which is characterized in that with the thread selector of any cylinder and / or ripping needle threads are fed.
  • the intarsia threads required for the production of intarsia or other patterns only to those points on the circumference of the knitted tube in which the intarsia patterns are to be formed, the intarsia patterns on any Circumferential location can be arranged. Between the intarsia sections of a row of knits, the intarsia threads do not have to be kept afloat on the back. You can rather end up of an intarsia section and re-fed to the next intarsia section. Depending on the pattern, this can sometimes achieve considerable savings in thread material. In addition, the transverse elasticity of the knitted fabric is not affected by afloat threads on the fabric back. Another advantage is that the entire knit hose can be used and not the yarn change points must be removed from the knitted tube as fabric rolls on known machines. If for the

  • the yarn transport units and the suction funnel can be arranged to each other such that the yarn supplied from a yarn transport unit, the free end of the suction funnel
  • Knit area is drawable. Then with a Ripplotnnadel a stitch or a tuck loin can be formed.
  • the transport units and the suction funnel can also be arranged so that with a cylinder needle a loop or a tuck loop can be formed.
  • the thread clamping and feed device has a drivable transport roller pair whose roles are moved apart.
  • the transport roller pair can be a
  • the thread feeding can be done alone with the transport roller pair.
  • the thread selection device has, for each feedable thread, a pair of transport rollers with the aid of which, with the assistance of the thread transport unit, a thread beginning can be fed to the suction funnel and / or the knitting needles.
  • the thread selector is needed only for inserting a thread beginning and for removing a thread from the knitting process.
  • the thread clamping and feed device can be deactivated during the knitting process.

  • the invention also relates to a method for producing a double-fabric knitted tube with intarsia patterns on one
  • 2-sided circular knitting machine which is characterized in that an intarsia thread required for the production of an intarsia pattern field is fed to the thread selection device of a needle of that fontur cylinder or dial plate on which the back side of the knit tube is made, and for integration of the beginning of the intarsia thread at least with this needle on the font a stitch is formed, before on the other fontur, on which the visible side of the knitted tube is made, stitches for the
  • Knit intarsia field and then knit at least one stitch with the intarsia thread on the first font before cutting off the intarsia thread.
  • intarsia patterns are formed with a plurality of short threads, wherein the thread beginning and the thread end of the intarsia threads are fixed in each case on the back by knitting in the fabric. There are thus no subsequent sewing to

  • the transport roller pair 15 and the thread transport nozzle 16 move the beginning of a thread 17 to a suction funnel 18.
  • the thread 17 can be moved from a dial needle 19 from a thread insertion area 20 into a knitting area 21, as illustrated in FIG. With the Rippidennadeln 19 and the thread 17 some stitches are formed on the back of the knitted fabric to incorporate the thread beginning in the fabric.
  • Fig. 3 shows the state of the thread clamping and feed device 14 after the thread insert into the Rippludennadeln 19.
  • This one can be on the Be floated back when knitting on the visible side with the thread 17 an intarsia field.
  • the basic thread can be fed to the needles 19, 22 in the same way as the intarsia thread 17 of thread selection devices 13 and during intarsia fields during knitting the
  • Knitting process can be taken.
  • the formation of the thread clamping and feed device 14 with a yarn transport nozzle 16 and a pair of transport rollers 15 is only one possible embodiment, which, however, is characterized in that only a few mechanical parts must be moved, whereby very high knitting speeds can be achieved.
  • the air flow of the nozzle 16 also ensures that can be dispensed with on Einreifer the thread insert.
