ABSTRACT:
Inserts for facilitating dispensing of wrapping material comprising an elongated web wrapped about a hollow cylindrical core. The inserts are telescopingly received within opposite ends of the hollow cylindrical core and are retained, in one preferred embodiment, by an elastic retaining member whose opposing ends are each releasably joined to the inserts. In another alternative embodiment, each insert is provided with a force-fit cylinder freely slidable relative to the insert and adapted to form a force-fit with the hollow cylindrical core, enabling the web supply to be rotated relative to the inserts, while an operator holds the inserts during a dispensing and wrapping operation.
