ABSTRACT:
Apparatus for cutting rolls of sheet material is provided with a pair of longitudinally stationary parallel knife blades positioned on opposite sides of a band saw blade which moves longitudinally to remove swarf from between the knife blades. The knife blades are supported on a blade carried band which is held under tension between spaced apart points on a mounting frame. A longitudinal gap in the knife blade exposes a section of the band saw blade to cut the core of a roll of sheet material.
