Abstract

There is described a method of manufacturing a flat friction ring which consists of a supporting ring (1) and a friction lining (2) provided on at least one side of the supporting ring and at least approximately forming radial oil grooves (3), which friction lining is first cut out of a friction lining web including slits (5) extending from at least one circumferential side for forming the future oil grooves (3), and is then glued onto the supporting ring (1). This method is characterized in that the friction lining (2) is cut out of the friction lining web in the form of a strip (7) and in the area of the connecting webs (6) between the friction lining sectors (4) separated from each other by the slits (5) is bent in a polygon-like manner to form a ring and is glued onto the supporting ring (1).
