ABSTRACT:
A die cutting insert for a rotary die cutter is disclosed as well as the die itself. The insert includes a base formed on a predetermined radius. The base has first and second spaced apart ends and first and second oppositely aligned surfaces. A knife is formed about the periphery of the first surface. The knife has a cutting edge and first and second side walls. The cutting edge has a width of less than about 0.005 inches (0.127 mm). In addition, the first side wall is aligned approximately perpendicular to the cutting edge while the second side wall is aligned at an angle of at least about 15.degree. relative to the cutting edge. The insert also includes a mechanism for removably attaching it to a die shaft. The mechanism includes at least one aperture formed adjacent to each of the first and second ends. The apertures extend completely through the base and each is sized to receive a threaded bolt. The threaded bolts can be torqued to a predetermined value to secure the insert to the die shaft. The rotary die cutter includes a die shaft having one or more replaceable and/or interchangeable die cutting inserts mounted thereto and is aligned to cooperate with a rotatable anvil roll. The die shaft and anvil roll are arranged to form a nip therebetween. Material which is to be cut can pass through the nip and will be cut into the desired shape of the die cutting inserts.
