Yarm feeder of weft knitting machine and method of feeding yarn for weft knitting machine

Abstract

A switching mechanism is provided for switching the position of a yarn feeding mouth to another and swinging a yarn feeder . The switching mechanism includes a push operating portion for changing a swing direction of the yarn feeding mouth and a height position thereof in cooperation with a leading means until a yarn feeder selected by the leading means feeds a yarn and is led from a stopped state. The push operating portion forms a lowering surface in a surface of the push operating portion. The lowering surface is used to further lower the yarn feeding mouth from a yarn feeding position so as to allow the yarn to pass under a backface side of the needle.

Description

technical field [0001] The invention mainly relates to a yarn feeding device for knitting intarsia patterns and a yarn feeding method for the part where the knitting yarn is switched. Background technique [0002] In the knitting of a row, several yarn feeders are switched and different knitting yarns are used to weave knitted fabrics without separation and form intarsia knitted fabrics. [0003] When weaving such intarsia knitted fabrics, such as Figure 12 As shown, a plurality of yarn feeders 12a, 12b that can be slidably arranged on the yarn guide rail are arranged, in order to use the yarn feeder 12a to knit the first knitting area A and the yarn feeder 12b to knit the second knitting area B, Yarns are to be fed separately, and alternately from the yarn feeder 12a to the yarn feeder 12b at the switching point of each yarn. , the yarn feeder 12a has passed the knitting boundary position P1 and is located at the left position (the state of the two-dot chain line in the f...

AI Technical Summary

Problems solved by technology

[0020] When the knitting needles 5c performing the tuck connection in this way are located away from the boundary portion of the knitted fabric, the swing of the yarn feeder must be increased, and the problem of increasing the size of the yarn feeder arises.

[0021] In addition, although image 3 The case of pulling-needle knitting was explained, but even if empty needles are not placed between knitting needles for stitch formation and knitting is done with full needles for knitting, for example, the fabric width of knitting area B is increased by one stitch to the right, and When the knitting needle 5a is used as the knitting area B, since the tuck connection is performed by the knitting needle located outside the knitting needle 5c, the same problem as that in the above-mentioned pull-needle knitting occurs.

[0022] In addition, because the distance between the knitting needles is enlarged by the flat knitting machine with a large travel distance, the above-mentioned problems may also occur when performing pull-needle knitting or increasing knitting.
