Manufacturing method and special tools for double-row down jacket decorative pleats

Abstract

The invention relates to down jacket manufacturing, in particular to a manufacturing method and special tool which are high in processing efficiency and quality and beneficial for producing double-row down jacket ornament folds in batches. The method includes the following steps of placing pleated fabric and down jacket surface fabric on an operation console of a double-needle machine in an overlapping mode, adjusting a bobbin case, a thread clamping device and the stitch length of the double-needle machine, rotating a screw shaft on a presser foot of the double-needle machine so that an included angle ranging from 20 degrees to 30 degrees can be formed between a bottom plate and the operation console, and finally conducting thread conveying. The presser foot used for achieving the method comprises the base and an installation part, wherein two grooves for needles to penetrate through are formed in the bottom plate, an adjustment part is arranged between the bottom plate and the installation part, and the adjustment part comprises the screw shaft, a spring and a pressing ord. Operation is easy, the garment quality is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the manufacture of down jackets, in particular to a method for making decorative pleats of double-row down jackets with high processing efficiency, good processing quality and convenient mass production and a special tool. Background technique [0002] In the process of manufacturing down jackets, it is often necessary to embellish some decorative materials or sew some decorative pleats on the clothes, so as to achieve the effect of beautifying the clothing. For the production process of double-row down jacket decorative pleats, the current method used is to use flat seams The machine first makes a row of creases, and then returns to make the next row of creases after the line is transported. [0003] This method of making double-row decorative pleats has the following disadvantages: (1) Due to the instability of manual operation, the double-row pleat lines cannot be completely parallel, and the distance between the pleat lines...

AI Technical Summary

Problems solved by technology

[0003] This method of making double-row decorative pleats has the following disadvantages: (1) Due to the instability of manual operation, the double-row pleat lines cannot be completely parallel, and the distance between the pleat lines made by different operators is different, and even the same operator The distance between the pleats produced will also vary. Due to the different timing, the formed pleats are dense and difficult to unify, which seriously affects the quality of the garment; (2) Repeated operations consume a lot of man-hours and work efficiency is low
