Abstract (en)
[origin: EP1197306A2] A rotary cutting die (10) includes a durable, flexible rotary die plate (14) having an inner surface and an outer surface. A cutting rule (12) that defines a cutting design is supported by the die plate. The cutting rule incluees a cutting edge (16) which extends above the outer surface of the die plate, and a support edge (20) disposed within the die plate. The support edge includes a plurality of keyhole shaped notches (22). Preferably, a plurality of S-shaped hooks (24) are connected to the key-hole notches, and serve to reinforce the rotary die plate and to support the cutting rule in the rotary die plate. The rotary die plate is preferably formed from a durable and flexible urethane-based material that exhibits a low shrink factor during curing or hardening. <IMAGE>
