Back buckle using elastic cloth reverse bag edge covering and production method of back buckle

Abstract

The invention relates to a back buckle using elastic cloth reverse bag edge covering and a production method of the back buckle. The back buckle and the production method are mainly used for solving the problems that the existing back buckle without a stitching seam can easily form an arch shape, and the whole of the back buckle does not fit enough. The back buckle comprises a back buckle body, elastic cloth and a rubber film, wherein the back buckle body comprises a basic cloth piece and a plurality of rows of annular buckles sewed on the front side of the basic cloth piece; the profile shapes of the elastic cloth and the rubber film are identical to that of the back buckle body; the elastic cloth shields and covers the front side of the back buckle body; the rubber film is pasted on the back side of the back buckle body; the edges of the left and right sides and the edge of the tail part of the elastic cloth, the back buckle body and the rubber film are pressed or are sewed through a stitching machine to form a pocket-shaped bag body structure; the bag bottom of the bag body structure is outwards turned out from the inside, so that the plurality of rows of annular buckles are outwards turned out from the inside of the bag body; the elastic cloth reversely shields and covers the rubber film; then, the elastic cloth and the rubber film are bonded on the back side of the back buckle body at the same time in a hot pressing bonding mode; the back buckle using the elastic cloth reverse bag edge covering is formed.
