Abstract
A stack of folded and glued corrugated paperboard boxes is slit in unison with a thin cutting blade having a linear cutting edge disposed parallel to the plane of the boxes and moved through the stack in an angular direction to slit essentially one box at a time. The stack is squared before slitting to align the box edges, however, the force of the blade on the stack as it moves therethrough holds the receding stack together such that the cut halves of each box may part laterally as the blade passes therethrough to avoid any crushing of the corrugated paperboard media.
