摘要:
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. The hub assembly is pivotally mounted to the second end of the support arm by the bracket attached to the second side of the hub assembly mounting plate, thereby assuring that the roll retaining force is applied axially through the center core of the roll without applying drag on the roll. Again, the hub may be freely rotatable. By way of example, the tensioning device may be a spring. Additional embodiments and variations also are described.
