Beating device for loom

Abstract

A beating device for a loom includes a plurality of rocking shafts disposed distant from each other in a width direction of cloth to be woven by the loom; a balance shaft disposed farther away from a reed than the rocking shafts and extending in said width direction, the balance shaft being disposed between the neighboring rocking shafts; and a pair of connection units for respectively connecting two opposite ends of the balance shaft with ends of the neighboring rocking shafts. The balance shaft is non-circular in cross-section such that a rocking-direction flexural-rigidity of the balance shaft is greater than a flexural-rigidity of the balance shaft in a direction perpendicular to the rocking direction.

Description

Technical field [0001] The invention relates to a beating-up device of a loom. Background technique [0002] The beating-up device of the loom has: a swing shaft that rotates in conjunction with the rotation of the main shaft of the loom, a plurality of sley feet mounted on the swing shaft, a sley clamp supported by the plurality of sley feet, and a fixed The reed on the reed clip. In this way, the reed, the reed clamp, and the sley foot become a connection with the swing shaft, swing around the swing shaft, and perform beating motion in conjunction with the rotation of the main shaft of the loom. However, the center of gravity of the pendulum shaft and its connected object is closer to the reed side position than the center of swing, and the center of gravity is greatly different from the swing center, that is, the pendulum shaft and its connected object are in an unbalanced state. Therefore, vibrations are generated along with the beating-up motion, and parts wear and noise are...
