Abstract: A rotary cutting die assembly is provided that includes a die cylinder, an anvil, and a die board mounted to the die cylinder. The die board includes a series of trim cutting blades. Disposed on the outside of each trim cutting blade is a trim stripper. Secured to the die board adjacent the outside of the trim strippers is a series of retainers that generally retain the trim strippers between trip cutting blades and the retainers. This generally prevents cut pieces of trim from being packed and wedged into a gap between the trim cutting blades and the trim strippers.

Abstract: A rotary cutting die apparatus for cutting and perforating corrugated board comprises a die board having one or more perforating rules. The perforating rule includes a series of spaced apart perforating segments disposed along one edge of the rule. Each perforating segment includes opposed angled shoulders that reduce or minimize the tendency of the corrugated board from becoming hung-up or held on the perforating segments when the perforating segments penetrate the corrugated board to form perforations therein.

Abstract: A cutting die for cutting corrugated board that includes a quick attach and detach securing mechanism. The blade securing mechanism allows a blade to be quickly and easily removed from a die board that forms a part of the cutting die, and allows a replacement blade to be quickly and easily inserted into the die board. The die board includes a first slit for receiving a blade and a second slit adjacent the first slit. The blade securing mechanism is associated with the second slit for spreading the second slit and effectively closing the first slit against the blade so as to secure the blade within the first slit.
