Abstract (en)

[origin: WO9727033A1] A die cutting insert (18) for a rotary die cutter is disclosed as well as the die itself. The insert includes a base (34) formed on a predetermined radius. The base has first and second spaced apart ends (36, 38) and first and second oppositely aligned surfaces (40, 42). A knife (44) is formed about the periphery of the first surface (40). The knife (44) has a cutting edge (46) and first and second side walls (48, 50). The cutting edge (46) has a width of less than about .005 inches. In addition, the first side wall (48) is aligned approximately perpendicular to the cutting edge (46) while the second side wall (50) is aligned at an angle of at least about 15 DEG relative to the cutting edge. The insert (18) also includes means for removably attaching it to a die shaft. The means includes at least one aperture (56) formed adjacent to each of the first and second ends (36, 38). The apertures (56) extend completely through the base (34) and each is sized to receive a threaded bolt (60). The threaded bolts (60) can be torqued to a predetermined value to secure the insert to the die shaft (14). The rotary die cutter includes a die shaft (14) having one or more replaceable and/or interchangeable die cutting inserts (18) mounted thereto and is aligned to cooperate with a rotatable anvil roll (12). The die shaft (14) and anvil roll (12) are arranged to form a nip (20) therebetween. Material (22) which is to be cut can pass through the nip (20) and will be cut into the desired shape (24) of the die cutting inserts (18).
