Abstract
PURPOSE: To enhance antiwear property and make fabrication and assemblage easy by a method wherein feeding teeth of a sewing machine are integrally casted along with a feeding rack by a die cast method and, thereafter, surface hardening treatment is carried out.
CONSTITUTION: Feeding teeth 12 are integrally formed on a feeding rack 11 from light alloy by a die cast method and antiwear property of the surface is increased by applying to a molded external surface hard chromium plating, an electrolysis method of a special metal such as chromium or the like or, when feeding teeth are aluminium alloy, hard alumite. Thereby, the said feeding teeth rack is easily fabricated in a low cost.
