Problems solved by technology

For example, the traditional process is to first complete the shrinkage operation on the single needle machine, and then complete the operation of sewing the rubber elastic band and the shrinkage fabric together on the herringbone sewing machine. In this way, a lot of man-hours are wasted by dividing the operation into two processes.
Due to the continuous increase of manufacturers, the competition is becoming more and more fierce, causing major factories to lower product prices to obtain more orders, which causes direct economic losses and becomes a vicious competition

Embodiment 1

[0024] figure 1 The basic structure of the improved presser foot according to the present invention is shown. The presser foot 1 is composed of two parts: an "L-shaped" presser foot plate 11 and a positioning seat 12. The lower part of the positioning seat 12 is provided with an elastic band for The first through hole 4 penetrated is also provided with a second through hole 3 for the lower needle position of the sewing needle, and the positioning seat 12 is equipped with an elastic steel sheet 5 for shrinking the cloth;

[0025] figure 2 It shows that the improved needle die according to the present invention is improved on the traditional basis: the bottom of the traditional needle die is ground into a bevel, and it can be seen that the bottom is a bevel from the trapezoidal side in the figure. The die 21 of the rear part of the needle die 2 has been blunted and is obviously lower than the tooth height of the front part.

Embodiment 2

[0032] Embodiment two: refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , provide a kind of needle car method that adopts the structural improvement of the herringbone sewing machine's presser foot and needle die to fold the small towel shrinkage of the herringbone sewing machine, comprising the following steps:

[0033] A. Improve the structure of the presser foot and needle die of the traditional herringbone sewing machine. The improved presser foot 1 is made of an "L-shaped" presser foot plate 11, which is positioned on the "L-shaped" presser foot plate 11. The front end of the positioning seat 12 is equipped with an elastic steel sheet 5, the lower part of the positioning seat 12 is provided with a first through hole 4 for the elastic band 8 to penetrate, and the "L-shaped" presser foot plate 1 is also provided There is a second through hole 3 for the lower needle position of the sewing needle 10; the bottom of the improved needle die 2 is ground into a...

Abstract

The invention discloses a structural improvement of a presser foot and a needle plate feed dog of a zigzag sewing machine and a stitching method of a zigzag reduced elastic crinkle. The presser foot is composed of an L-type presser foot plate and a positioning base installed on the L-type presser foot plate. A first through hole used for allowing an elastic rubber band to penetrate is formed in the lower portion of the positioning base, and a second through hole used as a stitch knitting position of a sewing needle is formed in the L-type presser foot plate. The needle plate feed dog is provided with multiple plate feed dogs. The elastic rubber band penetrates into the first through hole in the positioning base and penetrates out of the bottom of the presser foot plate, and meanwhile the elastic rubber band is bent to be overlapped with cloth installed at the bottom of the presser foot plate and penetrating between an elastic steel sheet and the needle plate feed dog. The bottom end of the L-type presser foot plate is higher than that of the elastic steel sheet, in this way, it is guaranteed that pressure exerted on the front end of the cloth is larger than that at the rear end, a crinkling effect is achieved, then operation of combining two procedures in a traditional process into one procedure is completed, machining time is greatly shortened, and working efficiency is improved.

Description

technical field [0001] The present invention relates to a herringbone sewing machine, more specifically, relates to the structure improvement of the presser foot and the needle die of the herringbone sewing machine, and also relates to a method of using a herringbone sewing machine to attach elastic bands on fabrics and fabrics in underwear production. The stitching method that shrinks the elastic band without shrinking, so that the elastic band and the shrunk fabric are stitched together smoothly. Background technique [0002] With the rapid development of the economy, people's living standards continue to improve, labor laws continue to improve, labor wages, factory rents and other expenses in various places generally rise, and overtime hours are also strictly controlled. As a result, the garment industry and production costs have also increased relatively, and due to the control of overtime hours, the output has also relatively decreased. Now each production factory gene...
