Abstract
A machine frame mounts a pair of upper and lower girder-like box beams (10,11) of heavy construction. A plurality of upstream upper scoring assemblies (28) and a plurality of downstream upper slitting assemblies (30) are mounted on the upper box beam. The lower box beam (11) also supports a plurality of upstream lower scoring assemblies (29) and a plurality of downstream lower slitting assemblies (31). The assemblies include rotatably driven slitting or scoring blades (32, 33). The box beams extend transversely of a traveling web (2). The assemblies include a motor (50) connected to be driven along its beam, and an encoder (52), with all of the motors and encoders being electrically connected to a programmable computer (54). The computer may be pre-programmed with the position and spacing of all of the assemblies, so that upon the provision of a single input signal all of the motors simultaneously drive all of the assemblies to their desired position. A bearing block (59) is engageable by an elongated cam rod (62, 63) extending along the beam. Rotation of the rod causes simultaneous locking of all assemblies in an array in position along the beam. Adjusting the caliper between oppo…
