Abstract: A roll supporting hub is adapted for acceptance of a plurality of rolls (one at a time), with each roll having a different predefined core width. The hub includes a hub body with a plurality of core support surfaces spaced circumferentially about a central rotation axis. One or more of those surfaces engage the core of the roll to secure the roll and hub together for coupled rotation. A stop surface on the hub body engages a first radial side of the core, while a radially retractable retainer surface 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 relative 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.

Abstract: A device adapted for applying L-shaped lengths of pressure sensitive adhesive coated tape on the peripheries of boxes moved past the device and for cutting the applied lengths of tape from a supply length of tape on the device, in which the mechanism for cutting the tape moves a cutting edge by which the tape is cut at about the same speed that the tape is moving in the longitudinal direction of the tape during engagement of the cutting edge with the tape.

Abstract: A device and method for laminating a barrier film to a blister pack utilizing a two-cycle, reciprocatory carriage assembly. The carriage assembly includes a tray upon which the blister pack is placed and reciprocated in and out of the device housing. During one cycle, the barrier film is prevented from contacting the blister pack by means of a pair of rollers which back the film away from the blister pack a predetermined distance. During the other cycle, the rollers advance the barrier film toward and in contact with the blister pack to apply the film. In addition, the rollers apply pressure through the film and blister pack against preselected pressure or bonding areas associated with the tray sufficient to bond the film to the pack. Different types of blister packs may be laminated by the device by changing the tray to include the necessary pressure or bonding areas.
