ABSTRACT:
The invention relates to a method for the production of a flange sleeve (10) especially for a sliding bearing. A strip of material is cut into lengths corresponding to the later periphery of the flange sleeve. The strip section (14) thus arising is rolled to form a hollow cylindrical sleeve with an open butt joint (12) and a collar (20) is placed around one or two sides. The open butt joint is expanded in the region of the collar to form a V-shaped slit. One or several recesses (18a,18b) are made in the region of the later open butt joint (12) on one or two of the longitudinal edges (16) of the strip section.
