Multi-purpose edge folding device

Abstract

The invention relates to a multi-purpose edge folding device, which belongs to the field of sewing of braided fabric and is mainly used for solving the problem that the edge folding process step is time-consuming and labor-consuming when processing braided bags and large cloth products. The multi-purpose edge folding device comprises an edge folding device main body and a pinching frame, wherein the edge folding device main body comprises a baseplate, an upper plate, a front body and a rear body; the baseplate and the upper plate are fixedly mounted on the pinching frame, the front body and the rear body are movably connected with the pinching frame, and a fixed fork plate is arranged on the outer side of the pinching frame; the rear body is sequentially provided with a crimping guide section and a shaping section from front to back; and the crimping guide section is sheathed on the front body. The multi-purpose edge folding device has simple structure and low processing cost, and can control the width of folded edges according to different required preset sizes of the folded edges; furthermore, the multi-purpose edge folding device can not only fold single edges, but also fold double edges, is applicable to sewing bottom mouths of the braided bags or edge folding for sewing the edges of bed sheets, window curtains and other large cloth products, and can further improve the production efficiency.

Description

technical field [0001] The invention relates to the field of knitted fabric sewing, in particular to a multi-purpose hemming device. Background technique [0002] Woven bags are widely used as a kind of packaging. The main production process is to use plastic raw materials to extrude film, cut, and single-way stretch into flat wires, weave them into cylindrical shapes through warp and weft, and finally fold the seamed edges of the bottom mouth. edge, forming the finished woven bag. Before using the sewing machine to sew the seam edge of the bottom opening of the woven bag, it is necessary to fold a section of the seam edge of the bottom mouth of the woven bag by hand before sewing this section, and then sew the next section after the machine stops . This manual operation mode not only has a large amount of labor and low work efficiency, but also is difficult to guarantee the quality of the finished woven bag. In addition, for large cloth products such as bed sheets and cu...

Problems solved by technology

This manual operation method not only has a large amount of labor and low work efficiency, but also is difficult to guarantee the quality of the finished woven bags.

In addition, for large fabric products such as bed sheets and curtains, in order to prevent the edges from being off-line, they also need to be hemmed and then stitched. Manual hemming also has the above-mentioned disadvantages.
