AI Technical Summary

Technical Problem

Knitted fabrics are prone to curling at the edges when sewing, which affects the sewing results.

Method used

The anti-rolling structure consists of a limiting component, a supporting bottom piece, and a supporting top piece. The limiting component is equipped with first and second limiting baffles, which are installed in a staggered manner to compress the fabric to make it flat. The supporting piece is an isosceles right triangle to increase friction.

Benefits of technology

This technology prevents knitted fabric from curling during sewing and keeps the fabric moving smoothly out of the sewing process, thus reducing production costs.

Abstract

本实用新型涉及针织面料加工领域，公开了一种防止针织面料卷边的结构，包括限位件，所述限位件的底端设置有支撑底片，所述限位件的顶端设置有支撑顶片，所述支撑顶片上设置有第一限位挡片，所述支撑底片上设置有第二限位挡片。该防止针织面料卷边的结构通过限位件对面料卷曲部分抚平，卷曲的衣片进入限位件，同时减小出口的空隙，让衣片离开出口时因为挤压，自然恢复平整状态，衣片面料从出口移出时，由于第一限位挡片和第二限位挡片为错位安装，衣片面料通过第一限位挡片和第二限位挡片之间的空隙时，衣片在出来时会自动受到向下的作用力，按照箭头的方向通过防卷边结构，解决了缝制时面料边缘卷曲问题。
