A punch member is resiliently mounted in one of two opposed rollers and is captured by structure that permits some radial movement of the punch relative to the roller. One or more dies are secured on the surface of the other of the two cooperating rollers and co-act with the punch to provide a shear cutting operation on a web that is moving between the two rollers. Both the punch and the die are readily removable from their respective roller. Means are also provided for adjusting the magnitude of the resilient force that acts radially on the punch.
