Apparatus for improving the alignment accuracy of eccentric workpieces, especially of piston rings

An apparatus for positioning eccentric piston rings which are provided with a marking is proposed. The individual piston rings are aligned in the stack according to their marking. To balance out differences in wall thickness or the like, the piston rings are raised from the drive device and pressed...

Zusammenfassung:	An apparatus for positioning eccentric piston rings which are provided with a marking is proposed. The individual piston rings are aligned in the stack according to their marking. To balance out differences in wall thickness or the like, the piston rings are raised from the drive device and pressed against stops, which are preferably coated with an elastic layer.
