ABSTRACT:
A pair of cylinder arbors have a plurality of arcuate cylinder segments extending circumferentially around a portion of the arbor. The segments are adjustable relative to the arbors in a circumferential direction. Each of the segments has a respective cutting and/or scoring die plate secured thereto. The die plates are relatively thin plates having lands formed thereon which cooperate with lands formed on the die plates on the other arbor to cut material moving through a nip defined by the segments. The material is cut by the lands into carton blanks for example, and broke. The broke is suitably separated from the carton blanks. The segments on one of the cylinder arbors carries a movable broke removing mechanism which includes pins which engage the broke. The pins extend through openings in the segments and die plates thereon and are actuated by an axially movable cam bar which is situated from a suitable cam. Further, a mechanism adjusts the cylinder arbors toward and away from each other for various carton blank print lengths. The segments which are positioned on the arbors are changed also for different print lengths. Specifically, different radial thickness segments are mounted on the arbors. Further, the apparatus is provided with an on-the-run adjustment mechanism for adjusting the radial dimension between the dies at the cutting nip.
