Abstract
A core end plug for mounting a roll of sheet material on a shaft. The plug comprises a cylindrical band of stiffly flexible plastic material having ends defining a longitudinal gap therein. A plurality of radial webs extend inwardly from the band. A pair of the webs are opposite each other and are provided with first and second elongated apertures which define identical acute angles to the diameter of the band. A third web defines third and fourth elongated apertures along a common major axis perpendicular to the diameter. A band is fitted into each end of a roll core and a mounting plate is inserted into each core end plug. A mounting shaft extends through central apertures in the mounting plates and through the fourth aperture in the third web. Pins in the mounting plate are received in the first and second elongated apertures.
