Leather is automatically sewn by a machine, and the two parallel edges of the leather can be sewn each time, so that sewing of leather products is greatly speeded up, the production efficiency of the production line is improved, and manpower is saved.

This button sewing machine is equipped with a vertically moving mechanism which drives the sewing needle (11) in the vertical direction while performing a needle swinging, a button holding mechanism (13), a fabric holding member (15) which is extended to the rear side, and folds back and holds the article (C) to be sewn, and a fabric moving mechanism (34) which moves and positions the article to be sewn. The button sewing machine is also equipped with button moving mechanisms (31, 32) which move and position a button (B), a looper (41) which forms a loop by catching a sewing thread, and a thread gathering member (42) which makes the sewing thread between the article to be sewn and the looper avoid the sewing needle which is lowered. A needle swinging limiting means (81) which performs a control for moving the button in the opposite direction from the needle swinging by the button moving mechanism so that the needle swinging may not be performed exceeding a limit amount for the needle swinging. The button sewing machine suppress a thread gathering defect.

The invention discloses a waterproof, anti-explosion and cutting-resistant high-strength double-layer toothed zipper and a method for manufacturing the same. The waterproof, anti-explosion and cutting-resistant high-strength double-layer toothed zipper comprises a left double-layer toothed chain belt, a right double-layer toothed chain belt and a zipper puller, the left double-layer toothed chain belt and the right double-layer toothed chain belt are meshed with each other in the left-right direction, an upper zipper chain, a lower zipper chain and a woven belt are sewn to form each double-layer toothed chain belt, and the zipper puller is used for opening and closing the left double-layer toothed chain belt and the right double-layer toothed chain belt. The waterproof, anti-explosion and cutting-resistant high-strength double-layer toothed zipper is characterized in that each woven belt is folded by one step, the zipper chains are respectively sewn at edges of outer surfaces of the upper and lower folded woven belts, and the two folded woven belts are sewn and connected with each other by harnesses. The waterproof, anti-explosion and cutting-resistant high-strength double-layer toothed zipper and the method have the advantages that the zipper is high in zipper chain and woven belt sewing speed, zipper chain and cloth belt connection strength, waterproof, anti-explosion and cutting-resistant performance and transverse strength, and the zipper can be opened and closed easily by the aid of the puller; each single-layer zipper chain is sewn with the corresponding woven belt when the zipper chains are required to be sewn with the woven belts, so that the sewing speed is greatly increased, and needles cannot be broken; and each single-layer zipper chain is sewn with the corresponding single-layer woven belt, and each double-layer zipper chain is sewn with the corresponding woven belt by the corresponding double-fold harness, so that the connection strength is doubled as compared with the traditional zipper.

The invention discloses a mold for sewing a back waist band, and relates to the technical field of sewing machines. The mold comprises a first guiding piece and a second guiding piece, the first guiding piece comprises a base plate, a semi-U-type hook with a rightward opening is arranged on the left side of the base plate, the second guiding piece comprises a support, the upper face of the support is provided with an upper U-type hook with a leftward opening, the lower face of the support is provided with a lower U-type hook with a leftward opening, and a lower half U-type hook body of the lower U-type hook is fixed on the base plate.
