Description

A twisting device with automatic roll changing mechanism

technical field

The invention relates to the technical field of textile equipment, in particular to a twisting device with an automatic roll changing mechanism.

Background technique

If one end of the spinning yarn is held and the other end is turned around, a yarn is formed, a process called twisting. Twisting is the process of twisting the drawn thin sliver like a towel when washing your face by using a rotary motion, so as to fix the longitudinal connection between the fibers. Twisting is a process of winding raw silk into a thread. For example, a thread consists of 24 threads. The 24 threads must be intertwined to make the thread stronger and more delicate.
