Abstract
An order transition in a corrugated is accomplished by creating an overlap of the slits made by the slitting tools associated with the expiring (running) and new orders. However, the slit tool associated with the innermost slit between the upper and lower level outs is maintained in slitting contact with the board to extend the slit line into further overlap with the slits made by the new order tools to create an order change region. A lateral cut is made to connect the innermost slit between the upper and lower level outs on the new order and the slit created by the tool delayed from withdrawal in the running order. Trim cut transitions are handled in the same manner.
