Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel needle selection device formed integrally with a hand knitting machine.

When knitting relatively complex patterns efficiently using a hand knitting machine, it is common to use a needle selection device that selects needles using pattern paper. However, a normal needle selection device is separate from the hand knitting machine, has a length that is only a fraction of the knitting width, and uses the same needle selection pattern to sequentially knit all needles from the end of the needle bed. This method requires repeated manual operations over a long period of time, is time-consuming, has a relatively low knitting efficiency, and has drawbacks such as the inability to knit large-sized patterns that cover the entire knitting width.

In order to solve the above-mentioned problems, this invention attaches a needle selection device corresponding to the entire length of the needle bed to the main body of the hand knitting machine, and allows automatic and highly efficient needle selection operation by operating a lever. To provide a needle selection device for a hand knitting machine that enables knitting of a large pattern that spans the entire knitting width.
