Abstract of the Invention A knife cylinder having a quick release mounting for a cross-cutting ox perforating knife blade is disclosed. The knife blade is mounted in a longitudinal groove in the periphery of the knife cylinder. It is held in place against a side wall of the groove by means of a retaining bar which is disposed within the groove. The retaining bar is normally urged against the blade by compression springs. In order to change blades, the retaining bar is pivoted away from the blade by means of an operating lever having pins insertable in openings in the outer wall of the retaining bar. This frees the blade for removal and enables insertion of a new blade. Endwise clamps are provided with resilient pads interposed between the clamps and the retaining bar to support the retaining bar against dislodge- ment while permitting pivotal movement thereof.
