Abstract
A blade clamping assembly for use with a rotary cylinder is designed to allow a quick change of a perforating blade, cutting blade or scoring blade. The assembly comprises an elongated retainer bar, an elongated backing plate and at least one compressive spacer. The inside faces of the retainer bar and the backing plate have a set of aligned cavities to hold the compressive spacers in place. The retainer bar preferably has a lower support ledge along an outside face to hold the blade and also has set screws with associated lock caps and resilient pegs to adjust the blade's height. Adjustment of the set screws allows a precise setting of the assembly and associated blade in a groove of the rotary cylinder. When the assembly is positioned in the cylinder's groove, the compressive spacers clamp the blade against a side wall of the groove. The blade is readily changed by forcing the retainer bar against the backing plate to compress the compressive spacers, thereby freeing the blade. The blade is quickly replaced with a new blade and the force removed to again clamp the associated blade against the groove's side wall.
