Patent ID: 8196501

Claim:
An apparatus for slabbing a roll having a generally cylindrical shape, an axis, an axial dimension, a radius, a core having a core diameter an outer circumference and a wall thickness, and a material having an outer circumference wound around the core, the apparatus comprising: a) a transport element capable of engaging the roll and of conveying the roll to a slabbing position, said transport element further comprising a pair of roll engaging elements capable of penetrating engagement of the core, b) a cutter capable of separating the material of the roll, c) an axial-traversing element capable of transporting the cutter at least along the entire axial dimension of the material of the roll as, or after, the roll is transported to the slabbing position, d) a radial-traversing element capable of transporting the cutter at least from the outer circumference of the roll to the outer circumference of the core as, or after, the roll is transported to the slabbing position, and e) an interface for inputting a core wall thickness, f) a controller capable of determining a maximum depth of cut according to a known position of the roll engaging elements in the slabbing position and the inputted wall thickness of the core, wherein the motion of the radial-traversing element is limited according to the determined maximum depth of cut.
