ABSTRACT:
A punch stripper is formed with an axially aligned aperture extending therethrough so that the punch stripper can be installed on the shaft of a punch. The punch stripper includes a cylindrical housing with a plunger telescoped within an axially aligned bore. An array of spring elements are axially aligned within the cylindrical housing such that a biasing force is exerted on one end of the plunger. A cap is held in position by a snap ring at the end of the housing most remote from the plunger. The array of spring elements exert a biasing force on the cap. An elastomeric O-ring is positioned within the cap so that a frictional force can be developed between the punch stripper and a punch that passes therethrough.
