Abstract
A bulk roll cutting apparatus with a safety linkage is used to prevent inadvertent gravitational falls of a blade. The apparatus has a frame holding the blade, the blade is movable between a cutting position and a retracted position. In the cutting position, the blade is positioned proximate to an arbor. At least one link arm is movably connected to the frame. An actuator connects between the at least one link arm and the blade. An adjustment device connects between the at least one link arm and the frame. The adjustment device controls a cutting depth of the blade relative to the arbor. A safety linkage connects between the at least one link arm and the frame, and the safety linkage prevents an inadvertent gravitational fall of the blade.
