Weft yarn cutting device of warp knitting machine for warp knitted fabric production

Technical Field

The utility model relates to a warp knitting cloth production facility technical field specifically is a woof cutting device of tricot machine for warp knitting cloth production.

Background

Warp-knitted fabric is a warp knitting method, and refers to knitted fabric manufactured by the warp knitting method. Warp knitting this name comes from weaving. The knitted fabric knitted by the warp knitting method is called warp knitting knitted fabric. Warp knitting differs from weft knitting in that the loops formed are arranged in the vertical or warp direction and are formed by the overlapping of adjacent yarns. The machines used for warp knitting appear somewhat like looms, with all the yarns wound on a warp beam, behind and above the knitting zone, and all the yarns fed into the knitting zone simultaneously. During the sleeving process, each yarn is controlled by a separate needle. However, the guide bar controls the position of the yarn, and the needle used may vary each time a stitch is made. Needle control can be implemented using a jacquard mechanism to produce a warp knit fabric with a complex pattern. In view of the technology used in warp knitting, the position of the yarn feeding device and the mutual nesting between parallel yarns, it is sometimes called a warp knitting machine.

Warp knitting machines form knitted fabrics by simultaneously knitting one or more sets of parallel aligned yarns on all the working needles of a warp feed machine, a process known as warp knitting and a fabric known as warp knit. The machine that accomplishes this is called a warp knitting machine.
