Definitions

  • the elastic properties of knitted fabrics can be determined by the insert of Weft threads are specifically influenced. While knits normally have a high transverse elasticity, can by the Weft insert Knitted fabric with at least lower areas Transverse strain are produced. This is used, for example, in medical Knitted like bandages, compression stockings and the like exploited.
  • weft insert special weft guide needed, which the weft leading to the center of the knitting on the Put on a course.
  • Standard thread guides put the knitting thread against it trailing the center of the knitting loop into the needle hooks. The Movement initiation thus takes place with one weft yarn guide on another Place as with a standard thread guide.
  • the weft insertion makes therefore, in the methods of the prior art, a special Equipment of the flat knitting machine with such special thread guides required.
  • the present invention has for its object to provide a method for To propose production of a knitted fabric with weft insertion, in which the weft insertion even with einflambaigen crocheted without large additional time can be spent.
  • the weft In contrast to the known method of weft insertion is method of the invention, the weft not on the course, but inserted into the hooks of individual, selected needles.
  • the fixation The weft thread is made with each needle, in the hook he is inserted, and with the adjacent mesh picture edges.
  • the number of fixations over the width of the knit can be according to the knitting technical Requirements of the fabric to be produced are selected.
  • the insert of the weft thread can both empty needles and in Mesh-bearing needles are made.
  • An empty needle, a weft In addition, a stitch from the opposite Pick up the needle bed.
  • the selection of the fixing positions of the weft This makes the knitting width very flexible. It can also be from Knitting row to knitting row again and again other needles for insertion of the Weft can be used.
  • the inventive method has the advantage that neither single-surface still with double-sided crocheting a transfer of stitches in front of the Weft insertion is required.
  • the weft insert is therefore a Process that takes little knitting time.
  • the weft should be pushed down so that the to the needles with inserted weft thread adjacent needles with their needle bottoms slide over the weft thread and thus can easily form stitches.
  • For pressing down the weft thread for example Hold-down boards are used. But also by the application appropriate knitting techniques for the production of the knitted fabric can Weft yarn pushed down so far that the movement of the too the needles with inserted weft thread adjacent needles through the Weft is not obstructed.
  • Another advantage of the method according to the invention is that the Weft insertion are performed by means of a standard thread guide can.
  • the insert of the weft thread takes place at the same point, that is trailing to the center of the knitting, as with the yarn guides with or the knitting threads.
  • the knitting cam illustration of Fig. 1 illustrates the weft insertion at the method of the prior art for the production of crocheted with Weft insert on a flat knitting machine.
  • the knitting lock 10 moves in the direction of arrow X.
  • the line S-M is the center of the knitting characterized. It is a weft yarn guide SFF and a standard yarn guide NFF provided.
  • the weft guide SFF places the weft in one Distance V leading to the center of the knitting cam SM on the not shown here Wale.
  • the emergence of needles 30 is just beginning at this position through the knitting cam 10.
  • the inserted in this position weft is from the underside of the knitting needles made in expulsion movement covered and therefore can not be detected by a needle hook.
  • Fig. 2 now illustrates the insertion of a weft thread 5 in the hook 31 a Needle 3.
  • the needle 3 is in the needle bed 1 in the direction of arrow Y outward and inwardly movable.
  • Fig. 2 shows the position of the needle 3 after the insertion of the Weft 5 and withdrawal of the needle 3, until the weft 5 at a Mesh image edge 21 of a mesh 3 adjacent to the mesh 3 is applied. In this position, the weft 5 is fixed exactly.
  • Fig. 2 shows a stitchless needle 3
  • Fig. 3 shows a stitchless needle 3
  • the needle 3 before the insertion of the weft thread 5 in their needle hook 31 also already can wear a stitch 6 of the knitted fabric.
  • the weft 5 is simply in addition to the mesh 6 inserted in the needle hook 31.
  • Fig. 4 shows in the same view as Figs. 2 and 3, a needle 3, which after the insert of the weft thread 5 still a stitch 6 'from the opposite Needle bed has taken over.
  • the weft 5 is here behind the Mesh 6 ', whereby the weft 5 on the outside of the knitted fabric is tied as soon as the stitch 6 'is knitted.
  • the weft thread is tied to the fabric inside, as soon as the stitch 6 is knitted, since here the weft 5 in front of the stitch 6 lies.
  • Fig. 5 illustrates in the view of FIG. 2 that a needle 3 ', the adjacent to the needle 3 with the in its needle hook 31 inserted Weft 5 is arranged, from the needle base 11 of the needle bed 1 lifts, to be able to slide with her needle bottom 32 on the weft thread 5.
  • This lifting of the needle 3 ' for example, by the knitting lock 10th or via switchable cams or casseroles on needle base 11.
  • the Lifting movement of the needle can also without a targeted control
  • the needle take place in that her rounded needle hook 31 'fixed on Weft 5 runs.
  • the needle 3 'to slide over the weft thread 5 to allow is the weft 5 side of the needle 3 down to press.
  • hold-down boards can be used become.
