Abstract
A cutting device for a roll of material wherein a cutter bar with a cutting blade fixed thereto is arranged between two upright posts. To cut the material from the roll a length of material is withdrawn from beneath the cutter bar and lifted against the cutter bar. The cutter bar is allowed to pivot about a longitudinal axis until an upstanding rib and a notch in the cutter bar clamp the upright posts between them and lock the cutter bar against further pivoting motion. The material is then torn across the cutting blade since the cutter bar cannot be further pivoted.
