ABSTRACT:
An apparatus and method for slitting a stack of folded corrugated paperboard boxes utilizes a thin slitting blade mounted for continuous movement through a slitting station and defining a vertical slitting plane. A stack supporting table straddles the slitting blade to support a stack of boxes in a stand-by position above the blade. Adjustable upstream and downstream squaring devices are operative to square and center the stack in the cutting plane and a vertically reciprocable ram operates to move the stack and the supporting table downwardly past the blade against a table biasing force to slit the stack into two half-size stacks. The squaring device is operable to re-square the slit half-size stacks prior to conveyance out of the slitting station. The slitting run of the continuous blade operates in a rigid blade holder which is adjustable to compensate for blade wear and to maintain the cutting edge of the blade in a fixed plane. The drum-like pulleys around which the slitting blade runs include a blade bias adjustment device which is used to maintain carefully monitored support of the blade in the blade holder to minimize wear and provide proper blade support along its full slitting run.
