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.

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.

A resilient-scrap ejector is provided for a cutting die. The scrap ejector includes an elongated body made of a resilient material. The elongated body includes a longitudinally-extending web. A plurality of lugs extend from opposite sides of the web and are separated by notches. The notches provide void spaces which allow for deformation for the elongated body when the elongated body is subjected to compressive forces. The scrap ejector is located in a cavity or recess formed in the cutting die for ejecting and stripping scrap severed from the blank. By providing displacement zones or voids, the height of the scrap ejector can be increased without compressing the material beyond the limits of its resiliency.

An elongated rubber ejector is mounted to a die board that forms a part of a cutting die and the ejector functions to engage cut corrugated board and eject the same from the cutting die. The rubber ejector includes upper and lower faces or surfaces with each face including a series of spaced apart raised lugs with a series of spaced apart voids or relief areas disposed between the lugs. Lugs and relief areas formed on one face are staggered with respect to the lugs and relief areas formed on the other face. In practice, the lugs are compressed during a die cutting operation. Once the corrugated board has been cut and the die board and an opposed anvil have been moved apart, the lugs and the ejector expand and in the process the rubber ejector engages the cut corrugated board and ejects the same from the cutting die.

An adjustable-height scoring rule includes a base member and a plurality of interchangeable scoring inserts which are detachably secured to the base member to adjust the height of the scoring rule. The base member includes insert-receiver for receiving the scoring insert. In one embodiment, the insert-receiver comprises a longitudinally-extending channel formed in the top of the base member. The scoring insert includes an insert portion that fits within the channel of the base member. In a second embodiment, the insert receiving means comprises a longitudinally extending boss, and the scoring insert includes a channel member that engages the boss on the base member.

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.
