ABSTRACT:
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.
