Problems solved by technology

In order to prevent soiling of the processing cloth, although it is effective to use a lower plate made of a synthetic resin material, it is more difficult to ensure the strength against contact resistance when moving left and right and back and forth

Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings showing the best embodiments.

[0031] Such as figure 1 , figure 2 As shown, the pattern seam sewing machine M includes a sewing machine body 1 and a workbench 2 . On the table 2, there are a lower platen 3 and an upper platen 4 that hold the processed cloth from top to bottom and can move in the front-rear direction (the direction parallel to the main shaft of the sewing machine) and the left-right direction (the direction perpendicular to the main shaft of the sewing machine). . The lower platen 3 and the upper platen 4 are moved by the operation of the feeder F based on the sewing data. The pattern sewing machine M sews patterns, designs, figures, etc. on the processed cloth by operating the sewing machine body 1 relative to the processed cloth that moves together with the lower platen 3 and the upper platen 4 .

[0032] The sewing machine body 1 includes a column 5 ver...

Abstract

The invention can hold upper platen and lower platen of the processing cloth which are supported by left and right movable plates contacting with upper surface of the work table. The left and right movable plates are connected to left and right feeding tables which move the upper platen and lower platen left and right, so that they can only move together with the upper platen and lower platen along left-right direction. Using this structure, the contact resistance on upper surface of the work table in weaving is just applied on the left and right movable plates thereby eliminating feeding error in left-right direction caused by elastic deformation on support portions of the upper platen and lower platen. Further, the invention can prevent the powder generated by wearing on contact portion of the work table adhering to the processing cloth thereby providing a feeding device of pattern sewing machine capable of improving sewing product quality.

Description

technical field [0001] The invention relates to a feeding device for a pattern sewing machine, in particular to a left and right moving plate arranged between the upper platen and the lower platen for moving and feeding the processed cloth and the worktable, which can reduce the contact resistance between the lower platen and the workbench the feeding device. Background technique [0002] A pattern sewing machine is a sewing machine that sews patterns, patterns, graphics, etc. on the processed cloth that moves in the front, rear, left and right directions on the workbench. The feeding device of the pattern seam sewing machine includes: a frame-shaped upper pressing plate and a lower pressing plate that maintain the processed cloth; a pressing arm that supports the upper pressing plate and the lower pressing plate and moves it; and independently makes the pressing arm parallel to the main axis of the sewing machine. Or a front and rear feeding mechanism and a left and right ...
