Compound needle for flatbed knitting machine

Abstract

[Problem to be solved] The present invention provides a compound needle for a flatbed knitting machine in which sliding resistance can be made small and opening / closing accuracy to an aperture of a hook by a tongue can be enhanced with a simple structure. [Solution] Tongues 1a, 2a have no bent and have linear shaped portions 1b, 2b provided at the rear side of the tongues 1a, 2a, so that the blades 1, 2 have stable finishing shapes and manufacturing thereof can be easily performed. Since lower portions of the blades 1, 2 are not bent in the blade groove, sliding resistance can be made small. Shoulder portions 1c, 2c which come out of the blade groove from rear portions of the tongues 1a, 2a are bent inward between the shoulder portions 1c, 2c opposed to each other such that front ends of the shoulder portions 1c, 2c make closer to and contact with each other so as to form contacting portions 1f, 2f, therefore, a centering effect can be obtained. A space generated between the tongues 1a, 2a is kept so that resistance when the hook 3a opens between the tongues 1a, 2a can be made small and opening / closing accuracy of the hook 3a can be enhanced.

Description

Technical field [0001] The invention relates to a composite needle of a flat knitting machine, which is accommodated in a needle groove formed on the needle bed of the flat knitting machine, and a slider for opening and closing a hook is formed by two blades. Background technique [0002] At present, in flat knitting machines, the knitting needles housed in the needle grooves formed on the needle bed are driven to slide in the needle grooves, so that the front hooks advance and retreat in the tooth mouth, and the knitting is supplied from the tooth mouth to the hook The thread is woven into a fabric. As a knitting needle, a compound needle combining a needle body having a hook at the tip and a slider that is relatively movable with respect to the needle body and has a tongue that opens and closes the hook at the tip is sometimes used. In the compound needle, a slider formed of two blades is also used so that it can also be separated by sandwiching both sides of the hook, and go ...

AI Technical Summary

Problems solved by technology

However, when the slider moves relative to the needle body, the sliding resistance increases and the driving load increases.

In addition, since the blade is bent in the portion of the curved portion, there is a possibility that the portion away from the side wall surface in the blade pocket may not have sufficient rigidity.

Furthermore, there is a possibility that the bent shape of the tongue piece and the bent portion becomes complicated, and the finished shape becomes unstable.
