Abstract

The invention provides a device for sewing creases of elastic trouser waists and an elastic trouser waist sewing method and aims at solving the problem that the cost for sewing the creases of the elastic trouser waists is high and the accuracy is low in the prior art. The device for sewing the creases of the elastic trouser waists comprises a sewing machine and a stretching device which are installed on a face plate, wherein the stretching device comprises a positioning mechanism fixed to the face plate and an adjusting mechanism for tensioning the elastic trouser waists. The positioning mechanism comprises a guide rail, the adjusting mechanism comprises a length adjusting member for adjusting the tension of each trouser waist and a position adjusting member for adjusting the positions of the trouser waists, and the length adjusting member and the position adjusting member are respectively and correspondingly installed at the two ends of the guide rail. The device has the advantages that the single-row guide rail is adopted, the problem that the positioning for installation is difficult due to a split guide rail in the prior art is avoided, the whole sewing device adapts to all sizes of trouser waists and is convenient to adjust, improvement can be performed on the basis of an existing lockstitch sewing machine, and the cost is greatly saved.

Description

technical field [0001] The invention relates to a sewing positioning device, in particular to a sewing device for elastic trouser waistlines and a sewing method for elastic trouser waist. Background technique [0002] The trouser waist is the place where the top of the trousers is tied with a belt. For people's wearing comfort, the trouser waist is mostly set as an elastic waistband.
