Abstract (en)
[origin: EP1731271A1] The tapper has an impact piston (9) forming a pressure chamber with a compressed air-supply between an impact plate (6) and the piston and another pressure chamber with a compressed air-supply between a cover (15) and the piston. The cover is provided with an opening (19), whose surface is smaller than the cross sectional area of the piston such that the piston seals the opening in an end position that moves away from the plate. An independent claim is also included for a method for operating a pneumatically-operating tapper.
