Abstract: A rotary plate is provided for fiber sliver depositing devices, in particular for draw frames and carding machines. The plate includes a spatially curved sliver channel made of a pipe element with two arcs of circles verging directly into each other. The sliver channel of the rotary plate is preferably made of special friction reducing steel. The plate may also include a cover attached to the bottom thereof also formed of the friction reducing material.

Abstract: The invention relates to an open-end rotor-spinning device with a rotor shaft which is mounted and driven in the wedge-shaped gap between supporting disks and to the free end of which is assigned an axial bearing. A simplified mounting, which also allows the supporting disks to be removed and exchanged while the machine is in operation, is provided because the rotor shaft (1) is mounted at two bearing points, of which one is formed by supporting disks (2, 3) arranged in the vicinity of the spinning rotor (10) and the second is a bearing (5) which absorbs axial and radial forces and which receives the free end (11) of the rotor shaft (1). An increase in the operating speed of the spinning rotor (10) without an increase in the running speed of the drive means (6) is achieved as a result of a reduction of the diameter of the rotor shaft (1) in the region of the drive means.
