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

technical field [0001] The invention relates to a manufacturing method of a deformed cam roller for adjusting warp let-off tension. Background technique [0002] Generally, woven fabrics are mainly made of two groups of yarns interwoven vertically and horizontally. The longitudinal direction is called warp yarn, and the horizontal direction is called weft yarn. It is widely used in clothing fabrics, decorative fabrics and industrial supplies. The weaving process follows the technical requirements of the vertical crossing of warp (longitudinal) and weft (longitudinal) yarns, and weaves gray fabrics through the coordination of five major movements of the loom, warp let-off, opening, weft insertion, weft beating, and winding. Conventionally, this horizontal and vertical weaving method makes the varieties and colors of woven fabrics relatively single. In order to change this traditional weaving method, we mainly designed a special device to control the amount of warp feed of so...
