| 1. 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.
