Abstract
A loom guide bar blade for automatic weaving machinery such as an air or water jet loom wherein the surface of the blade which contacts yarn is nitrided to form a nitrided hardened layer. When this blade is used in automatic high-speed weaving machinery, wearing and the like at contacting points of the blade with the yarn are prevented. As a result yarn fluffing from its being abraded by a roughened blade surface is minimized.
