Leno heald capable of automatically resetting

Abstract

The invention provides a leno heald capable of automatically resetting, the leno heald comprises a base heald A, a base heald B and a riding heald, the riding heald comprises two supporting legs, the two supporting legs of the riding heald are inserted between the base heald A and the base heald B. The opposite surfaces of the base heald A and the base heald B are provided with a clamping plate A and a clamping plate B which are arranged in a staggered manner, flexible connecting pieces are connected between the tails of the two supporting legs of the riding heald, and the flexible connecting pieces cross between the clamping plate A and the clamping plate B. The leno heald is simple in structure and high in efficiency, and the riding heald can return along with the base heald without installing an external structure.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a leno heald capable of automatic reset. Background technique [0002] The leno heddle is a key component of weaving leno fabrics. The riding heddle of the existing leno heddle is usually controlled and reset by a spring, such as the patent application number CN201710101184.4, which also uses a magnet for reset, such as the application number 200680047043.9 patents, and the use of multi-link structure to control the movement of the riding heddle following the base heald, such as the Posileno device of Gross Company. However, with spring control, the riding heddle will receive additional tension from the spring when it follows the base heddle up and down, and the loom needs to reserve a place for the installation of the spring, and an additional mechanism needs to be installed to fix the spring, which is extremely inconvenient and affects the installation density of the leno heal...

Problems solved by technology

However, with spring control, the riding heddle will receive additional tension from the spring when it follows the base heddle up and down, and the loom needs to reserve a place for the installation of the spring, and an additional mechanism needs to be installed to fix the spring, which is extremely inconvenient and affects the installation density of the leno heald. Machine operating efficiency is also affected

Using a magnet for reset requires installing a magnet of a certain size on the base heddle, which increases the thickness of the leno heddle and affects the installation density of the leno heald. Moreover, the magnetic force generated by the magnet is insufficient and unstable, and often cannot reliably restore the riding heald. There is a certain risk of failure, but the use of multi-link structure greatly increases the installation space of the whole machine, which is extremely inconvenient to install, and it is impossible to provide a riding heddle reset function for each leno heddle, so the leno heddle cannot be used in jacquard fabrics superior
