ABSTRACT:
A method for producing the latch bearing in a latch needle for textile machines of the type in which a latch is pivotably mounted in a longitudinal slot between two cheeks of a needle shank by a hinge pin passing through mutually aligned transversely extending bores in at least one of the cheeks and a bearing portion of the latch between the cheeks. In accordance with the method a cylindrical wire is provided with transversely extending notches at intervals corresponding to the length of a hinge pin. The notched wire is converted by hot or cold treatment into a bittle, hard state. Individual hinge pins are broken off from the wire at the notches, and are subsequently inserted into the bores in the cheeks and the bearing portion of the latch to be securely fixed there.
