ABSTRACT:
A punching device includes a fixed frame adapted to support punch means in alignment with a ram. An assembly of the punch, a guide and stripping sleeve and a stripping spring is removable as a unit and such assembly includes means by which such assembly is retained together, especially during handling away from the frame of the punching device. To this end, the punch has a radial opening, such as a circumferential groove, in which there is disposed a friction member, such as of plastic, which has an interference fit with the interior of the stripping sleeve.
