Problems solved by technology

[0018] Due to such a situation, in the past, the presser foot 1 was appropriately replaced according to the thickness of the material to be sewn, and it took a lot of time to replace the presser foot 1 at a sewing site where thin and thick materials are mixed. There is a problem of reduced work efficiency
[0019] In addition, in the case of dealing with fabrics whose thickness changes along the direction of sewing, it is impossible to cope by replacing the presser foot 1, making it difficult to obtain a good-quality sewn product.

Abstract

The present invention provides a presser foot of sewing machine, including an assistant guiding component locating on a pressing claw of one part of left-right pressing claws extending towards the front of a position for receiving needle between a needle plate, for clamping upper cloth and projecting into a guiding path between a pressing claw of the other part, to optimize the path between the pressing claw of the other part and the assistant guiding component, holding the upper cloth and the lower cloth with a benign standing gesture, feeding material to a position for setting fixed blade and movable blade to cutting the upper end edge uniformly, so as to prevent bad tailoring availably due to imperfectness of cutting.

Description

technical field [0001] The present invention relates to a presser foot of a sewing machine for performing stitching in which the end edges of two pieces of cloth are overlapped and sewn together. Background technique [0002] The stitching is a sewing form used for sewing the crotch portion of briefs and shorts, and is performed with a sewing machine having a cylindrical bed with a small diameter. This sewing machine has: a needle plate (Stitch plate) provided on the upper surface of the front end portion of the cylindrical base; and a presser foot (Presser Foot) located above the needle plate, which can be raised and lowered manually or automatically. The above seaming is carried out as follows: the two pieces of fabric are overlapped up and down by a predetermined width from their respective end edges, clamped between the lowered presser foot and the needle plate, fed to the needle drop position, and then lowered to the The needles at the needle drop position are sewn to ...
