Description

Overlock machine presser foot piece structure

Technical Field

The utility model relates to a sewing machine equipment technical field especially relates to a overlock machine presser foot spare structure.

Background

The overlock is also called as overlock, and is a term in the clothing industry, and English is "overlocking". In the process of producing clothes, because the materials used by terylene and the like are generally synthetic fibers, after the materials are cut to be relatively hard, the silk threads at the edge seams of cut clothes materials are scattered due to the relatively high hardness of the silk threads, so the silk threads need to be overlooked: and (4) stamping a circle of edge at the edge seam by using a special stamping machine so as to prevent the silk threads in the cloth from being scattered.

The presser foot refers to the thread used in the process of 'overlock' in the garment production process and the needle seam thereof. The main purpose of the overlock is to prevent the yarns of the cut pieces from being loosened, so the requirement on the strength of the overlock thread is not high. In order to save cost, the overlock thread is generally made of polyester interlaced yarn, is not twisted and has lower strength than sewing thread. The difference between the sewing thread and the ordinary sewing thread is that the overlock line is made of polyester filament yarn without twisting, while the sewing thread is made of polyester staple fiber with twisting, and the overlock machine is a sewing machine which can be used for overlock in the clothes production process. Currently (most overlock machines are three-needle five-thread machines and three-needle six-thread overlock machines, the latter sometimes being referred to as "universal sewing machines" because of the possibility of varying the number of needles and threads.

The presser foot of overlock machine mainly fastens the fixed to the part that is sewed, and traditional presser foot structure mostly adopts the monolithic iron plate, and installs most fixed mounting, unable angle regulation to monolithic iron plate structure, the area of pressing is difficult to be adjusted, above these problems just need to improve equipment, consequently, we propose an overlock machine presser foot spare structure.
