The present invention generally encompasses a device for removing waste material from a blank. The invention includes a rotatable stripping pin housing and a stationary cam. The stripping pin housing includes a number of radially extending grooves in its axial surface. Each groove terminates at an aperture located in the stripping pin housing's circumferential surface. A stripping pin apparatus having an radially outwardly extending stripping pin capable of penetrating waste material and an axially extending cam follower is position within each groove. Each cam follower is engaged within a cam track in the stationary cam. The stripping pin housing is placed so that the stripping pins will engage waste material (and not the blank) as the material passes the device. Thereafter, the stripping pin housing is rotated causing the cam followers to travel along the cam track so that the radial location of the cam track determining the radial position of the stripping pins.
