Abstract

A joint expansion device for a garment comprises: a pair of right and left fabric portion forced transfer devices that forcibly transfers fabric portions at two sides toward the joint length directionwhen the fabric portion in which a joint is to be formed is expanded toward two sides of the joint length direction; a joint moving guide which is disposed at the central or substantially central position of the pair of right and left fabric portion forced transfer devices to enable the joint of the garment that is forcibly transferred to move along the length direction; and a joint expansion mechanism that applies an extension force in a direction perpendicular to the joint length direction to enable the joint to be expanded in the length direction when the joint is forcibly moved and guidedalong the joint moving guide to forcibly transfer the left and right fabric portions. With this configuration, the joint can be reliably, quickly, and externally expanded over the entire length withminimal effort and time, and without requiring special labor, thereby improving the productivity of the garment with better completion.

Description

technical field [0001] The present invention relates to a seam expansion device for clothing, which is used to expand the seam in the contracted state, so that it will be overlapped when passing, for example, like sportswear, spats, stockings, tights, pajamas, etc. When the above-mentioned two pieces of fabric parts in the clothing with seams in a contracted state are sewn together to form a seam in a contracted state, when the above-mentioned two pieces of fabric parts are unfolded to both sides in the direction perpendicular to the longitudinal direction of the above-mentioned seams, the two pieces of fabrics that are unfolded The end edges of the parts will be butt seamed. Background technique [0002] As the object clothing, with Figure 13 The sportswear SW shown here is explained as an example. The sportswear SW is made by using an overlock sewing machine Figure 13 The parts shown by the arrows a, b, c, d, e, f, along the direction of fabric travel Y (refer to Figur...
