Abstract

A knife shaft assembly (13) is disclosed for use in a rotary die cutter (10). The knife shaft assembly includes a rotatable die shaft (14) having an outer circumference (16) and having a defined width (W). At least two die cutting inserts (18) are mounted on the outer circumference (16) of the die shaft (14). Each of the inserts has a first surface (40) and a knife (44) formed about the periphery of the first surface (40). The knife shaft assembly also includes a compressible material (62) positioned between the die cutting inserts (18) which prevent the buildup of material waste there between.
