Abstract: An adapter for a dispenser, the adapter including at least one carriage unit which is slidably mounted within a dispenser. In selected embodiments, the adapter of the present invention includes a frame which is mountable within a dispenser, the carriage unit slidably mounted within the frame. Each carriage unit includes a pair of spaced apart arms, each arm having an outboard surface and an inboard surface. An outboard pin is disposed on the outboard surface, the outboard pin configured to slidably engage a channel of a dispenser. An inboard pin may be rotatably attached to the inboard surface, the inboard pin configured to engage a coreless roll of material. In selected embodiments, the frame may include a base and a pair of spaced apart side rails, each side rail extending upwardly from the base. A rear support may also be provided, the rear support extending upwardly from the base.

Abstract: A hub assembly for use in a dispenser for a roll of sheet material having a core, which hub assembly includes a mounting plate having a first side and a second side, a hub attached to the first side of the mounting plate, and a bracket attached to the second side of the mounting plate for pivotally mounting the hub assembly on a support. If desired, the hub may be freely rotatable. Also provided is a hub support assembly for use in a dispenser for a roll of sheet material having a core. The hub support assembly includes a hub assembly and a support arm, in which the hub assembly may be the hub assembly just described. The support arm has a first end and a second end, in which the first end is adapted to be pivotally mounted on a support, and the first end has a tensioning device to apply a retaining force to the roll and to permit compensation for varying product widths.
