Embodiment Construction

[0018] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] see figure 1 and figure 2 , the present invention provides an elastic band seaming device, which includes an opening clip 10 for transporting an elastic band with side openings along the length direction, and the opening clip 10 has an upper clip part 11 and a lower clip part 12 extending along the length direction, so The upper clamping part 11 and the lower clamping part 12 are connected at one end and the other end is gradually opened to form an opening 13. The upper clamping part 11 has an upper fold bent towards the inside of the opening at the edge of the opened end. The bent portion 110 , the lower clamping portion 12 has a lower bent portion 120 bent toward the inner side of the opening at one edge of the opened end. The included angle of the opening 13 gradually decreases along the length direction of the opening clip 10 . ...

Abstract

The invention provides a flat seaming device for an elastic belt, which comprises an open clamp conveying an elastic belt in the length direction, wherein the elastic belt is provided with a side opening; the open clamp comprises an upper clamp part and a lower clamp part both extending in the length direction; one ends of the upper clamp part and the lower clamp part are connected, and the other ends of the upper clamp part and the lower clamp part gradually stretch to form an opening; the upper clamp part is provided with upper bending parts bending towards the inner side of the opening on an edge of the stretched end; and the lower clamp part is provided with lower bending parts respectively bending towards the inner side of the opening on the edge of the stretched end. Compared with the prior art, the flat seaming device for the elastic belt, provided by the invention and used for flat seaming the elastic belt provided with the side opening and interlayer cloth, is convenient and practical, simplifies the elastic belt flat seaming process, improves the production efficiency, reduces operating errors of manufacture with multiple processes, enables the distances from flat seaming stitches to edges to be more uniform, and increases the yield of products.

Description

technical field [0001] The invention relates to an elastic band hemming device used for seaming an elastic band hemming with one side opening to interlayer fabric. Background technique [0002] At present, the production process of stretch-sewing the elastic band with one side opening to the interlayer fabric usually includes three steps: (1) first fix the elastic band on the edge of the interlayer fabric with a single-needle machine; The elastic band and interlayer fabric are seamed by the machine; (3) After the finished product, the fixing thread used to fix the elastic band in step (1) is removed. In this way, not only the production steps are cumbersome, more time-consuming, and the production cost is higher, but also often cause the defect that the stitches of the cover seam are uneven from the edge, and the yield rate of the finished product is low. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of th...
