Problems solved by technology

[0005] The minimum needle pitch of this kind of stitch can reach 0.7mm, and the narrowest hemming width is 3mm, and a knot will be formed on the edge (as shown in the P position in Figure 2), which will affect the aesthetics, especially for some extremely thin materials that cannot meet its requirements. Closer and narrower hemming requirements

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0015] It can be seen from Figures 1 and 4 that the present invention includes: a needle A-1, a lower looper A-3 mounted on the lower looper rocker A-2, an upper looper guide rod A-4, and a needle plate A -6; It also includes a fork needle D-1 that only plays the role of pulling the thread and no longer uses suture; the fork needle D-1 is installed on the upper looper guide rod A-4;

[0016] The shape of the fork needle D-1 is: a cylindrical mounting handle 11 (approximately 7mm long), a cylindrical connecting body 12 (approximately 10mm long), 95-100° between the two Included angle, there is also a fork 13 at the front end of the working part.

[0017] It can be seen from Fig. 3 that the loop of needle thread C-1 is used to penetrate into the loop of the lower looper thread C-3 of the overlock material and into the sewing material C-2, which is expos...

Abstract

The present invention relates to a tipping structure of a high-density edge processing machine of an overedger. The tipping structure comprises a needle (A-1), a lower bending needle (A-3) arranged on a lower bending needle rocker (A-2), an upper bending needle guide rod (A-4), a needle plate (A-6), and a forked needle (D-1) for thread poking without using stitching; the forked needle (D-1) is arranged on the upper bending needle guide rod (A-4). The beneficial effects of the present invention are that: denser, narrower and more pleasant stitching is realized based on the changes of a few spare parts, and the thread consumption is reduced.

Description

Technical field [0001] The invention relates to a high-density edge testing machine in an overlock sewing machine, in particular to the edge covering structure in the edge testing machine. Background technique [0002] High-density edge testing machine is a kind of overlock sewing machine used for hemming and decoration of handkerchiefs and socks splicing. [0003] It can be seen from Figure 1: This machine consists of a needle A-1 installed on the needle bar connector, a lower looper A-3 installed on the lower looper rocker A-2, and a lower looper needle installed on the upper looper. The three parts of the upper looper A-5 on the guide rod A-4 cooperate with the needle plate A-6 to realize the stitches shown in Figure 2. This stitch pattern is formed by the needle thread and the two hook threads of the upper and lower loopers. [0004] It can be seen from Figure 2: The loop of needle thread B-1 penetrates the sewing material from the upper loop of upper looper thread B-4 on the...
