ABSTRACT:
Improved slotter wheel apparatus (20) for use in the formation of box blanks is provided which includes a rotatable wheel (22) supporting a shiftable blade holder (24) and a slotting blade (26), with cooperating cam track (174) and follower (86) structure for selective shifting of blade (26) between an extended slotting position and a retracted blank-clearing position. An activation/deactivation assembly (30) allows the operator to separate cam track (174) from follower (88), thereby permitting use of apparatus (20) as a conventional, high speed, fixed blade slotter. A shock absorbing assembly (27) including a bridge piece (138) operably coupled with blade holder (24) and resilient pads (152, 154) serve to absorb potentially destructive mechanical loads experienced during outward shifting of the blade holder (24) and blade (26).
