Patent ID: 7523536

Claim:
A method of installing a core adapter in a roll core, the core adapter comprising: a hollow cylindrical sleeve; a plurality of longitudinal apertures formed through the sleeve, each longitudinal aperture extending substantially parallel to a longitudinal axis of the sleeve; a plurality of radial apertures formed in the sleeve; each radial aperture extending substantially perpendicular to the longitudinal axis of the sleeve; a sharp stud in each one of the radial apertures, each stud having a bottom extending into one of the longitudinal apertures; the method comprising: (a) inserting the adapter into the roll core to position an outward end of the adapter flush with an end of the roll core; (b) bracing the adapter to prevent further axial movement of the adapter into the roll core; and (c) driving the studs substantially perpendicularly away from the longitudinal axis of the sleeve and into the roll core.
