Problems solved by technology

[0004] It can be seen from this that at present, to make backpacks or handbags, it is necessary to first carry out the sewing operation of sewing the two sewn fabrics together, and after the sewing operation is completed, the hemming operation of sewing the hemming material to the edge of the suture can be carried out. Therefore , it takes a lot of production time to complete a backpack or handbag, which makes it difficult to improve production efficiency

Abstract

The invention relates to a double-needle hemming sewing machine. The double-needle hemming sewing machine has a needle bar mechanism, a crimping device and a feeding mechanism. The device can move the hemming material along a feeding path and a discharging path sequentially, wherein the feeding mechanism can simultaneously drive the hemming material and the sewing fabric to move along the discharging path and the sewing path respectively, so that The sewn fabric passes through two needles in sequence, and then the binding material passes through only one needle, so that one of the machines sews the sewn fabric to form a stitch, while the other needle secures the binding material to the The fabric is sewn to allow the hemming material to cover the stitches, whereby the present invention can complete the sewing operation and hemming operation in one operation process.

Description

technical field [0001] The invention relates to a sewing machine for sewing backpacks or handbags, in particular to a double-needle hemming sewing machine capable of simultaneously completing sewing and hemming operations to improve production efficiency. Background technique [0002] The sewing machine is mainly to combine several layers of sewing materials with each other through sewing, and, with the increasing demand for various applications, there are currently many types of sewing machines on the market, and different styles of sewing machines can be used It is suitable for the sewing operation of different sewing objects. [0003] At present, backpacks or handbags are mainly stitched by sewing machines. When you want to produce backpacks or handbags, you need to use a lockstitch sewing machine to sew two sewn fabrics to each other to form a suture. The object is moved to the hemming sewing machine, and the hemming sewing machine is allowed to sew the hemming material...
