Summary:A roll supporting hub 10 is adapted for acceptance of a plurality of rolls 12 (one at a time), with each roll having a different predefined core width. The hub 10 includes a hub body 16 with a plurality of core support surfaces 28a, b, c, d, spaced circumferentially about a central rotation axis 15. One or more of those surfaces engage the core 14 of the roll to secure the roll and hub together for coupled rotation. A stop surface 44 on the hub body engages a first radial side of the core, while a radially retractable retainer surface 68 engages a second radial side of the core. The retainer surface is secured to the hub body in one of a plurality of possible predefined axially disposed positions to the stop surface, each of which corresponds to one of the predetermined core widths of the roll being supported by the hub. The retainer surface is supported by a spring which is retractable within a slot extending axially between opposed support surfaces on the hub body.
