A core slabber for removing paper from the cores of fiberboard rolls where the cores are to be reused comprising a horizontal core support, a clamp plate on the core support, a camshaft internally of the core support to move a pin outwardly radially from said core support to move said clamp outwardly to engage the interior of the core. Tracks parallel to the axis of said core support carry a cutting blade on a blade carrier. A mechanism for moving said cutting blade accurately into engagement with selected depths of outer layers of paper on the core in order to cut the paper several layers at each pass in order to remove the paper and prepare the core for reuse. A sensor is also provided to limit the movement of the blade toward the core and also to limit and reverse the traverse of the blade parallel to the axis of the core.
