Abstract: An apparatus for slitting a running paperboard web includes a thin high speed rotary slitting blade that is plunged through the moving web and into a slot between a pair of anvil rollers supporting the web on the opposite side. Because the slitting blade and the anvil rollers are vertically separated and pre-positioned before order change, an adjustment apparatus is provided to spread the anvil rollers axially apart to provide an open gap with a large target for blade edge when it is plunged through the web and into the slot. The anvil rollers are then closed against the opposite faces of the blade for running operation. Preferably, the anvil rollers are mounted on brackets hinged together below the rollers to move the opposite upper edges of the rollers between the opened and closed position in the manner of a clam shell. The anvil roller assembly is also adjustable in the machine direction to compensate for reduction in rotary slitting blade diameter with blade wear.
