A hardened wear spot on a textile element is formed by applying high energy heat to a selected small area of the element which has been previously hardened and tempered to provide the proper spring characteristics for an operating textile element. The intensity and time of application of the high energy heat and the cooling after heat cut-off are carefully controlled to provide a small area of full hardness which is completely separated from the remaining tempered portion by a buffer zone of less hardness than either the tempered portion or the full hardness area. The new textile element made by this new method is a textile element with the major portion having a predetermined spring characteristic for an operating textile element. A small area of full hardness is located at a predetermined location to provide wear resistance. A buffer zone having less hardness than either the full hardness area or the major tempered portion completely separates the full hardness area from the major portion.

Textile element

Method of making textile element

A laser beam is directed towards a workpiece immersed beneath the surface of a liquid coolant. An exothermically reactive gas is directed through the liquid coolant to the workpiece under sufficient pressure and velocity to sweep away a sufficient amount of the liquid coolant to expose part of the workpiece to the laser beam for cutting.

Apparatus and method for laser cutting

The body of the needle has at least one lateral opening to relieve stress, absorb shock, and dampen vibrations. The opening or openings are located so as not to extend to the top or bottom of the latch needle body.

Latch needle for knitting machines

This is a knitting machine element for use in the slots of machines for circular knitted fabrics. The element is twisted so as to press it against the slot walls to produce a uniform pressure and predictable positioning of the element thereby eliminating rocking, misalignment, and improving frictional characteristics.
