Abstract

PURPOSE:To improve quality and working efficiency by a method wherein the tips of surface and back shoulder yokes sewn on a rear body are folded back in a state to adhere a press plate to a base plate and a rotary support plate, and after the front body is inserted in the folded-back upper surface of the back shoulder yoke, the rotary support plate is turned over to join the folded part of the surface shoulder yoke. CONSTITUTION:Surface and back yokes 72a and 72b sewn on a rear body 70 are inserted on a base plate 30, and the surface shoulder yoke 72a is moved round onto the upper surface of a rotary support plate 56. The tip of the back shoulder yoke 72b is protruded from a flange 32 by a distance equivalent to a folding-back width, and a first press plate 46a is rotated to the upper surface to fold back the tip of the back shoulder yoke. Simultaneously, a second press plate 46b is rotated to the upper surface of the surface shoulder yoke 72a to fold back the tip thereof. The upper end of a front body 74 is inserted in the folded back tip of the back shoulder yoke 72b, and the rotary support plate 56 is rotated to the upper surface thereof with which the tip of the surface shoulder yoke 72a is brought into contact. The joint part is guided to a sewing part 14 to press-sew the tip of the front body 74.

Description

[Detailed Description of the Invention] ■ Purpose of the Invention (1) Industrial Application Field This invention is for sewing left and right front bodies to the front end of a shoulder yoke sewn to the back body when sewing clothing. , relates to a method and a feeding device for stacking a front body and two shoulder yokes on the front and back and feeding them into a sewing section.

(2) Conventional technology For example, when sewing a dress shirt, the lower end of the front shoulder yoke is sewn to the upper end of the back body in a sewn pattern, the lower end of the back shoulder yoke is sewn in a folded pattern, and then the front shoulder yoke is sewn to the upper end of the back body. The upper ends of the left and right front bodies are sewn to the left and right front ends of the back shoulder yoke and the back shoulder yoke.

When sewing the left and right front pieces to the front and back shoulder yokes, fold the front ends of the front and back shoulder yokes to the inside, insert the upper ends of the front pieces inside, and press-stitch from the front side, or , Turn the front shoulder yoke and back shoulder yoke inside out, align the front edges, insert the top edge of the front body into the combined inside and sew them together, then turn the front shoulder yoke and back shoulder yoke inside out again, and then flip them inside. The seams are sewn from the front surface at the positions of the seams.

(3) Problems to be Solved by the Invention However, during the sewing process, it takes time to fold the shoulder yoke to the inside and iron it, and even when the front and back shoulder yokes are turned inside out and sewn together. Since the back body is sewn, the workability is poor, and two work steps of joining and press-stitching are required, which is labor-intensive. In addition, the operator has to grasp the fabric with both hands in order to guide the fabric to the sewing section of the sewing machine, which has the disadvantage that the stitches are not straight and are easily distorted.

The present invention has been made in view of the above-mentioned problems, and its purpose is to fold the front ends of the front shoulder yoke and the back shoulder yoke into the inner surface using a presser plate and a laminated plate, and in that state, insert the front end into the inside. This system is designed to insert the front shoulder yoke and feed it into the sewing section of the sewing machine while being clamped at the folded part between the front shoulder yoke and the back shoulder yoke.The work efficiency of attaching the front body to the shoulder yoke is high and The present invention provides a front body attaching method and a front body attaching feeding device which are linear and produce high quality products.
