Abstract

A sheet member is transported over a knife anvil by a feed conveyor movable from a first position adjacent the knife anvil to a second position overlapping the knife anvil. The feed conveyor has a moving belt which is driven in a forward direction for transporting the sheet member over the anvil and to a takeaway conveyor. The belt is driven in an opposite direction to pull the cut leading edge of the sheet material away from the end of the feed conveyor after cutting of the sheet material and during movement of the feed conveyor to the overlapping position over the anvil. A rotary knife is moved along the knife anvil and is mounted for rocking of the knife in a direction opposite to the direction of travel of the knife to provide a positive shear point.
