A cutting apparatus for removing remnant paper from a paper butt roll. A beam-mounted saw rocks toward and away from the butt roll and cuts remnant paper from the roll's core. An arm-mounted wheel senses the thickness of remnant paper on the roll, and causes a block-and-tackle positioning mechanism to rock the beam and saw to a proper position for cutting the paper from the roll. A conveyor moves the butt rolls past the saw, and the height of the conveyor may be adjusted to accommodate various diameters of butt rolls.
