Abstract
In one embodiment, a take up reel comprises a core having a generally open interior and an outer surface that is adapted to hold a sheet-like material that is wound around the core. Also, the core defines at least one slot. A slider member is slidable within the slot between a home position and an extended position away from the outer surface. In this way, when the sheet-like material is wound around the outer surface of the core when the slider member is in the extended position, the sheet-like material is spaced apart from the core in the region of the slot. Further, when the slider member is moved to the home position, the tension in the wound sheet-like material is reduced to facilitate removal of the core.
