Problems solved by technology

This way of manual operation usually leads to poor control of the width of the webbing, distortion and deviation, and the need to stop from time to time for manual adjustments, resulting in slow sewing speed and low sewing quality. Finally, manual labor is required. The process of threading the rope into the webbing is largely dependent on the individual skills of the operator, and it is time-consuming and labor-intensive. It is particularly backward in today's industrialized operations.

Embodiment Construction

[0013] The present invention will be described in further detail below: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following examples.

[0014] Such as Figure 1-2 As shown, the double-needle presser foot in which the cord is integrated, two needle holes 2 are evenly arranged on the presser foot 1, and the front end of the presser foot 1 is inclined upward to set a limit stay bar 3, and the bottom surface of the presser foot 1 A through groove 4 is arranged at the center of the two pinholes 2 .

[0015] The end of the presser foot 1 symmetrical to the limit bar 3 is provided with a fixed frame 5, through which the double-needle presser foot is fixedly connected with the sewing machine.

[0016] The limiting brace 3 is a cylindrical U-shaped structure with the same width as the presser foot 1 capable of a...

Abstract

The invention relates to a rope and braid integrated penetration double-needle pressure pin. Two needle holes are uniformly formed in the pressure pin, wherein the front end of the pressure pin is upwards equipped with a limiting pulling strip in an inclined mode; and through slots are formed in centers of the two needle holes in the bottom surface of the pressure pin. The rope and braid integrated penetration double-needle pressure pin can ensure that sewn rope-braid is consistent in width, and is not twisted and deformed, solves manpower and material resources, and improves working efficiency. The rope and braid integrated penetration double-needle pressure pin is compact in structure, and is popularized and applied in practical production.

Description

technical field [0001] The invention relates to the field of sewing machine components, in particular to a double-needle presser foot through which a cord is integrally inserted. Background technique [0002] Traditional sewing machines often need to use manual operation when sewing fabrics and belts combined with ropes. First, one end of the belt is sewed on the fabric, and then the other end of the belt is sewed on the fabric. This way of manual operation usually leads to poor control of the width of the webbing, distortion and deviation, and the need to stop from time to time for manual adjustments, resulting in slow sewing speed and poor sewing quality. Finally, manual labor is required. The process of threading the rope into the webbing largely depends on the individual skills of the operator, and is time-consuming and laborious, which is particularly backward in today's industrialized operations. Contents of the invention [0003] The purpose of the present inventio...
