Hat-like inserts for use with supply rolls comprised of a hollow cylindrical core having an elongated web of indeterminate length wrapped about said core. The hat-like inserts have a slightly tapered, generally cylindrical shaped side wall terminating at the narrow diameter end in an integral closed end surface and being opened at the wider diameter end thereof and having an integral continuous flange encircling said open end and extending radially outward therefrom. The inserts are pressed into opposing ends of the hollow core with said flanges overlying at least the adjacent end of said core and preferably a portion of the end of the rolled up web. A curvature provided in the region where the open end of said cylindrical side wall joins said flange maintains the flange a spaced distance from at least the adjacent core to prevent surface contact therebetween and thereby reduce frictional drag. Outwardly projecting ribs are provided about said cylindrical side wall to minimize surface contact between the insert and the interior periphery of said core. Inwardly directed ribs are provided along the side wall of said insert which, together with the outwardly projecting ribs, facilitate gripping of the insert by the fingers of an operator.
Inserts And Cooperating Retaining Means For Use With Web Dispensing Means
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.
