Sewing machines for threading and string drawing on waist of garment

Abstract

The invention relates to a threading sewing machine on the upper and middle waste of clothing, which comprises a double needle flat bed sewing machine, a threading belt transmission rack linked with the nose of the double needle flat bed sewing machine and a threading hole used for the threading and arranged on the bottom of the threading belt transmission rack. The lower end of the threading belt transmission rack and a holding foot of the double needle flat bed sewing machine are correspondingly provided with a belt mouth. Both ends of the pressure foot are provided with a check block, and the space between two check blocks is equal to the width of the belt. With the adoption of the invention, the process of threading is much simpler and easier, in which the regular trails and the uniformity without wrinkles are achieved. Therefore, the technical standards are ensured, and the work efficiency is improved by more than 3 times.

Description

technical field [0001] The invention relates to a drawstring sewing machine for wearing waistbands on garments. Background technique [0002] On skirts, trousers, some women's tops and other clothing, as well as military and police forest camouflage tops, there are drawstring or strapping processing technologies. In the past, the processing of such garments relied heavily on the technical level of workers. The sewing process was carried out with a single-needle machine, and one side of the yarn tape was first joined to the garment. Then cover the drawstring or strap under the yarn tape, and then use the other side of the yarn tape to join the garment. Such an operation process is easy to cause the fabric between the two stitches to be twisted, and no matter what kind of finishing method is used, the fabric cannot be restored to level. In addition, since the sewing is performed by looking at the reverse side, the stretching strength of the fabric is different during the sew...

AI Technical Summary

Problems solved by technology

Such an operation process can easily cause the fabric between the two stitches to be twisted, and no matter what finishing method is used, the fabric cannot be restored to its smoothness.

In addition, since the sewing is performed by looking at the reverse side, the stretching strength of the fabric is different during the sewing process, which will cause the stitches of the fabric to be different, and the distance between the two lines of stitches will be different, making the appearance of the fabric stitches more difficult. Poor, it is difficult to guarantee the technical standard requirements, the quality of this process depends entirely on the level of workers' technical level

Furthermore, during the operation, the rope and the yarn tape covered on the rope and the exact position of the garment to be processed are adjusted while sewing, which virtually increases the labor intensity of the workers and also increases the processing time of this sequence. , resulting in low labor efficiency and high manufacturing costs
