Description

Movable sinker in flat knitting machine

The present invention relates to a movable sinker of a flat knitting machine, and more specifically, a simple structure capable of guiding a knitting yarn reliably and accurately with knitting needles and pressing a loop to support a variety of beautiful patterns. It is for the movable sinker of the flat knitting machine.

Basically, in the knitting of the knitting structure by the flat knitting machine, the sinker provided at the tip of the needle and the knitting yarn supplied while supporting the loop by the knitting needle are guided to the hook portion of the knitting needle, and the supplied knitting yarn is held at the hook portion of the knitting needle. The knitting needle is retracted and the old loop is passed through the knitting yarn to become a new loop, and knocked over to form a knitting fabric. Knitted fabrics were so monotonous that they could not meet the needs of recent luxury and diversification.

Therefore, as knitted fabrics are made of expensive knitted products of various patterns according to the current demands of consumers, many application tissues or change tissues are applied in addition to the basic knitting tissues, and one or several loops are retained without escaping from knitting needles. In the next course, which is necessary, escape multiple loops at once, giving thickness, stiffness, and perforation effect to the fabric, and to the projection and color yarn. It is also possible to obtain a pattern effect by the tuck stitch (tuck stitch) to produce a unique aesthetic is applied a lot.

However, the currently used flat knitting machine often has a large number of loops that are separated from the latch portion of the knitting needles in order to knit such multiple jaw knitting tissues. Moreover, the thickness of the knitting yarn used is large or bulky property is large. In this case, it was well known that the jaw knitting using the jaw knitting was a high-grade consumer's response because it could not be knocked down accurately, but there were many problems in applying the jaw knitting tissue to the actual knitting product.

The inventors of the present invention have made diligent researches to produce flat knitting machines capable of organizing a variety of beautiful and expensive knitted products in view of the current situation in the world as a result of the present invention, and as a result, the new By providing a component sinker to work closely with the knitting needles, we have developed a movable sinker that can accurately guide and support multi-colored and multicolored knitting yarns.

That is, in the present invention, since the structure of the movable sinker is simple, the production is easy, and the operation is made accurately, even when the multi-jaw knitting tissue is formed by simultaneously supplying knitting yarns of different colors and thicknesses, the deviation from the knitting needles causes defects in the product Economical flat knitting machine with low failure rate of relatively inexpensive unit price, which can lead to accurate oversight by guiding precisely even if the knitting yarn with large bulky property is not caused or malfunctioned.
