A core slabbing machine for the removal of paper wound on a mill roll core, to thereby permit reuse of the core. The machine includes a horizontal core-receiving mandrel and a carraige which moves horizontally back and forth above, and aligned with, the mandrel. The carriage carries a freely rotatable cutting wheel which is forced downwardly by a pneumatic cylinder onto the paper to be removed from a core. Each horizontal pass of the rotary cutting wheel cuts through a number of layers of paper determined by the force on the cutting wheel. This action is automatically controlled and continues until the cutting wheel reaches the core surface exterior after a number of cutting passes. The freely rotatable cutting wheel exerts a force on the core and paper substantially at right angles to the core and its supporting mandrel, thus obviating the need to anchor the core relative to the mandrel.
