Abstract
An expandable, self-adjusting core plug which will maintain a fit between core plug and an out-of-round web roll core. The present invention accomplishes this by providing a core plug with a number of individual, elongated beveled ribs and a corresponding beveled spindle, both of which cooperatively and axially adjust the thickness of the core plug to meet variations in the inner diameter of the core.
