Abstract

The invention discloses a method for making a let-off tension adjusting deformation cam roller. The method includes the steps of parameter design of a cam base circle profile curve, design of a cam spire profile curve and design of a transition profile curve from the base circle profile curve to the cam spire profile curve; the diameter of a cam base circle appropriately ranges from 20 mm to 40 mm; the diameter of the cam spire profile is 2-4 times that of the cam base circle; the design of the transition profile curve from the base circle profile curve to the cam spire profile curve mainly is related to let-off variable scale speed change. According to the method, the let-off tension adjusting deformation cam roller is made so that the weft density can be changed, the traditional effect that weft yarns are transversely arranged on fabric is changed, and the curve appearance of the weft yarns is generated. The weft density can be changed; besides, colored threads can be used for generating attractive double-curve patterns, and the variety grade of woven fabric is promoted.

Description

Warp let-off tension adjustment distortion cam rollers making method
Technical field
The present invention relates to a kind of warp let-off tension adjustment distortion cam rollers making method.
Background technique
Usual woven is mainly interwoven through latitude in length and breadth with two groups of yarns, is longitudinally called warp thread, is laterally called weft yarn, be widely used on garment material, decorative fabric and industry articles for use.Its weave course follows the technological requirement through (longitudinal direction), the square crossing of latitude (longitudinal direction) yarn, by the warp let-off, opening, the wefting insertion of loom, beats up, batches five large motion coordinated and knit and make grey cloth.This smooth vertical and horizontal weaving mode routinely, makes the variety design of woven more single.For a change this traditional method for weaving with, we are mainly through designing the how many device of extraordinary control section warp yarn supplying amount, and change this situation, straight weft yarn of making over becomes bending change, to enrich the variety design of woven.The emphasis designing the how many device of extraordinary control section warp yarn supplying amount is warp let-off tension adjustment distortion cam rollers.
Summary of the invention
