ABSTRACT:
The chiplessly formed open end spinning rotor (1) has, in the region of its collecting groove (11), a surface which has not been contacted by shaping tools. To produce it, a pot (3) is first made by stretching and stamping of flat material. This is then secured in its radial position independently of shaping tools. The peripheral wall of the pot (3), in the region between the later collecting groove (11) and the open edge of the pot (3), is upset inward by any optional kind of plastic deformation and the region later to be the collecting groove (11) by unsupported plastic deformation ["against air"].
