Patent ID: 8104174

Claim:
A method for producing a piston for a shock absorber piston-cylinder, comprising the steps of: a) providing a sealing blank and a piston body, the piston body having a circumferential surface; b) pushing the sealing blank over the piston body; c) pressing the sealing blank onto the piston body; d) cutting off the sealing blank on a first end; e) forming a first sealing lip with a first desired profile on the first end; and f) widening the sealing blank on the first end, such that the first end does not bear against the piston body, wherein the sealing blank forms a sealing collar for the piston body, the sealing collar having an outer circumferential surface, an inner circumferential surface, a first peripheral surface and the first sealing lip, the sealing collar extending around the circumferential surface of the piston body covering at least a part of the circumferential surface of the piston body in an axial direction, the first peripheral surface connecting the outer circumferential surface and the inner circumferential surface with each other on the first end, and the first sealing lip being delimited by the first peripheral surface and the outer circumferential surface and being configured evenly in the circumferential direction.
