Template for crocheting lower hem facing

Abstract

Disclosed is a template for crocheting a lower hem facing. The template is composed of a bottom plate, a pad plate and a cover plate; the cover plate and the bottom plate are coaxially hinged to one side of the pad plate, and the pad plate, the bottom plate and the cover plate are respectively provided with a pad plate sewing through groove, a bottom plate sewing through groove and a cover plate sewing through groove which all can be coincident with one another; the outer periphery of the cover plate is uniformly provided with a plurality of suction devices, the suction devices are communicated with one another through air pipes, the outer periphery of the bottom plate is uniformly provided with a plurality of suction grooves, and the suction grooves are communicated with one another through air pipe accommodating grooves. The template solves the technical problems that in the process of crocheting lower hem facings, the processing mode is complicated, positioning is inconvenient, theprocessing redundancy is not uniform, and the requirement for the operation level of workers is high; through the hinged cooperation of the pad plate, the bottom plate and the cover plate, the workerscan complete all operation simply by placing the template in an automatic template sewing machine, and the technical problems that when the lower hem facings are crocheted, the processing mode is complicated, and the requirement for the operation level of the workers is high are fundamentally solved.

Description

technical field [0001] The invention belongs to the fields of material processing and textiles, and relates to a processing template specially used for an automatic template sewing machine, in particular to a hook hem welt template. Background technique [0002] In the production process of the existing hook hem welt, usually the fabric to be processed is first marked, folded and ironed according to the marked mark, and then directly sewed. However, although this sewing method can meet the basic processing needs, it cannot guarantee the regular appearance of the finished hook and hem welt, the processing allowance is not uniform, and the processing efficiency is low. The processing specifications of the hook hem welt are also not guaranteed. [0003] Traditional garment enterprises mostly use automatic template sewing machines for continuous sewing stitches of medium and large quantities of garment pieces. When using an automatic template sewing machine, the fabric to be p...

AI Technical Summary

Problems solved by technology

[0004] However, there is no mold dedicated to hook hem welt in the existing formwork, and in the use of the mold, there are often improper fixation and inaccurate positioning, which lead to an increase in the defective rate. Therefore, in view of the deficiencies of the prior art, the It is very meaningful to transform the template specially used in the automatic template sewing machine
