Intelligent stepped adjusting device for multi-group yarn output tension

Technical Field

The invention relates to the technical field of intelligent textile, in particular to an intelligent stepped adjusting device for multi-group yarn output tension.

Background

Warping is a process in which a certain number of warp yarns are wound in parallel on a beam or a beam according to a predetermined length and width. The most important thing in the warping process is to control the consistency of the tension of tens of warp yarns and even hundreds of warp yarns wound on the warp beam at the same time.
