Patent ID: 7661344

Claim:
An apparatus for die cutting comprising: a rotary cutting roller having a first end surface and a second end surface, a circumferential surface, at least one indicia affixed to a predetermined location on the first end surface, and at least one cutting knife located on the circumferential surface, the cutting knife corresponding to a predetermined die cutting configuration, wherein the location of said at least one indicia on the first end surface corresponds to the number and circumferential placement of said at least one cutting knife; at least one end sensor for detecting the at least one indicia on the first end surface, wherein said at least one end sensor is operable from a fixed location; an anvil roller disposed in cooperating rotational movement with the rotary cutting roller to provide a nip, the nip being positioned for receiving a web material, whereby the web material is die cut in the predetermined die cutting configuration, the web material having pre-applied longitudinally spaced web indicia; at least one web sensor for detecting the pre-applied longitudinally spaced web indicia on the web material; an encoder for detecting rotational movement of the anvil roller; and a processor for receiving information from the end sensor, the web sensor, and the encoder, and translating this information for adjusting the rotational movement of the rotary cutting roller to thereby register said die cutting configuration on said web.
