Abstract
Der spanlos geformte Offenend-Spinnrotor (1) weist an seinem offenen Rand (12) eine Verstärkung (14) auf. Diese ist als eine am Außenumfang des offenen Randes (12) vorgese hene Bördelung (14) ausgebildet. Bei der plastischen Verfor mung des Ausgangsmaterials in die endgültige Form des Spinnrotors (1) wird dessen Gleitwand (10) auf eine übermä ßige Länge gebracht. Anschließend an diese plastische Verformung wird der offene Rand (12) des Spinnrotors (1) durch Umbördeln verstärkt. The non-cutting open-end spinning rotor (1) instructs a reinforcement (14) on its open edge (12). This is as one on the outer circumference of the open edge (12) hene flare (14) is formed. In the plastic deformation the starting material into the final form of the Spinning rotor (1) whose sliding wall (10) on an overm brought length. Subsequent to this plastic Deformation becomes the open edge (12) of the spinning rotor (1) reinforced by crimping.
