ABSTRACT:
A device is provided for finely working exterior circumferential faces of self-tensioning piston rings which are combined into a packet. The device includes a cylindrical sleeve having an interior wall surface against which the circumferential faces of the rings lie under their own tension. Two discs are disposed between which the rings are arranged in the sleeve with a slight axial spacing. The packet of rings is rotatable relative to the sleeve and movable back and forth within the sleeve, with at least one of the discs being pivotal about the longitudinal axis of the sleeve. A mechanism is provided for pivoting the one disc about a pivot angle that is variable and arrestable for subjecting the rings to a tilting movement with the sleeve.
