ABSTRACT:
A locking device to be used with a rotating mandrel to lock the core of a roll of material that is to be wound or unwound into engagement with the mandrel. The mandrel has a cylindrical exterior surface, a rotatable cantilever support at an inward end, and an outward unsupported end adapted to receive the core of the roll of material. The locking device comprises a locking hub for compressively engaging and locking the core. The locking hub includes at least one pin fixedly coupled to an interior cylindrical surface as well as an engaging surface directed toward the inward end of the mandrel to engage the end of the core. The locking device further includes a sleeve mounted on the mandrel and having structure defining a groove or grooves formed in a generally spiral shape for lockingly engaging the at least one pin. Alternatively, the grooves are formed in the cylindrical exterior surface of the mandrel proximate the unsupported end thereof, obviating the need for the sleeve.
