Title:
HEALD ROD FOR TEXTILE MACHINE
Document Type and Number:
Japanese Patent JP2008133557
Kind Code:
A
Abstract:
To provide a heald rod for a textile machine having abrasion resistance and toughness and remarkably reduced processing cost.
The heald rod 1 for a textile machine is made of a steel material, and the area 2 repeatedly colliding with a heald is hardened by the surface-hardening with a semiconductor laser while leaving the area which does not repeatedly collide with the heald to secure the toughness by the non-hardened area 3. A remarkable cost reduction of the heald rod can be achieved by the omission of a tempering operation.
