Description

Technical Field

[0002] Spinning is a very ancient activity. Since prehistoric times, humans have known how to spin shorter fibers into long yarns and then weave them into cloth. Spinning refers to the act of taking animal or plant fibers and twisting them to form a continuous and infinitely extended yarn for weaving. The twist of the yarn itself will make the fibers naturally and tightly hold together, which is very beneficial for weaving or knitting. Spinning machine is the full name of a tool that processes raw materials such as thread, silk, and linen into silk threads and then weaves them into cloth. The yarn clamping device is an important component on the spinning machine to ensure uniform yarn tension and maintain normal yarn transportation.
