Description

TECHNICAL FIELD

[0002] The cloth of cloth sofa is woven by warp yarn, and the warp yarn is a yarn package arranged in longitudinal order on a loom. During weaving, it is used to bear the tension of the loom and is the basic constituent yarn of the fabric. The warp yarn is usually composed of fibers by weaving or knitting, and has high strength and wear resistance. The warp yarn plays an important role in the weaving process, and its quality and performance directly affect the quality, performance and appearance of the fabric. When the warp knitting machine knits the sofa fabric, a winding device is needed to collect the knitted fabric.

[0003] According to the winding device for warp knitting machine of sofa fabric (publication number: CN117585495A) disclosed in the above-mentioned application, the tension of the cloth is gradually relaxed, which avoids the increase of friction during the winding process of the cloth, and prevents the generation of static electricity caused by the increase of friction and the influence on the winding quality of the cloth.

[0004] However, during actual use, the winding roller increases the uniform pressure on the tablecloth in the longitudinal direction by adjusting the pressure arm, which improves the tightness and uniformity of winding. As the winding roller winds more cloth, the pressure between the roller on the pressure arm and the cloth increases, resulting in greater friction, which is not conducive to the winding of the cloth. In view of this, we propose a winding device for warp knitting machine of sofa fabric. UTILITY MODEL CONTENTS
