Problems solved by technology

However, since there is no special tool, it can only be grasped by the operating skills of the operator; because it is difficult to control the middle size (difficult to ensure that the distance between the two sewing lines and the seam is equal), it is impossible to guarantee the sewing quality and efficiency, which directly affects the knitting. And the quality grade and delivery date of woven products

Abstract

The invention relates to a textile sewing machine component and aims to provide a middle dividing presser foot provided with an ultrashort seam allowance knife. The middle dividing presser foot can ensure that the quality of a sewed middle dividing pressing line meets the requirements. According to the technical scheme, the middle dividing presser foot provided with the ultrashort seam allowance knife comprises a connector, a pressing plate and a first elastic element, wherein the connector is fixedly connected with the bottom of a pressing rod, the pressing plate is hinged to the connector through two hinging lugs on the upper part of the pressing plate and provided with a pinhole, and the first elastic element applies force to the connector and the pressing plate separately. The middle dividing pressure foot is characterized in that the pressing plate is also provided with the seam allowance knife which is embedded into a seam during sewing; the seam allowance knife is positioned onthe front side of the pinhole of the pressing plate and protrudes forwards and downwards by a certain distance.

Description

technical field [0001] The invention relates to a component of a textile sewing machine, in particular to a centering (centering) presser foot of the sewing machine equipped with an ultra-short seaming knife. Background technique [0002] In clothing knitting and woven products, it is often necessary to carry out the middle parting line on the curved parts such as collars and clips (two pieces of fabric 40 connected by sewing, the left and right sides of the seam 20 at the connecting part A sewing thread 30 is sewed at about 1-2 mm respectively, and the distance between the two sewing threads and the seam is required to be equal or close; see Figure 14 , Figure 15 ) for reinforcement and decoration. However, since there is no special tool, it can only be grasped by the operating skills of the operator; because it is difficult to control the middle size (difficult to ensure that the distance between the two sewing lines and the seam is equal), it is impossible to guarantee...
