Abstract
A roller assembly for a sheet material transport assembly is disclosed, wherein skewing of the transported sheet material relative to the transport assembly is reduced. The roller assembly includes an elongate shaft having a compliant layer disposed about the shaft. A relatively non-compliant layer is disposed about the compliant layer to form a tire, wherein the non-compliant layer has a circumference, which is substantially unchanged upon operable loading of the roller assembly.
Claims25
A roller for a roller assembly, the roller comprising:
- (a) a shaft;
- (b) a first tire mounted relative to the shaft, the first tire including:
- (i) a compliant core affixed relative to the shaft for rotation with the shaft;
- and
- (ii) a non-compliant layer connected to the core for rotation with the core.
A tire for a roller for transporting a sheet material, the roller including a shaft, and having an unloaded state and a loaded state, the tire comprising:
- (a) a compliant core connected relative to the shaft for rotation with the shaft;
- (b) a non-compliant layer connected to and surrounding the compliant core and, the shaft, the compliant core and the non-complaint layer being concentric in the unloaded configuration, and the shaft being offset from the concentric state in the loaded state, the non-compliant layer selected to preclude a deformation of the non compliant layer in the loaded state sufficient to induce skewing or scuffing of the sheet material upon contact with the sheet material.
A roller having an unloaded concentric configuration and a loaded non-concentric configuration, the roller comprising:
- (a) a shaft;
- (b) a non-compliant layer;
- and
- (c) a compliant core intermediate the non-compliant layer and the shaft, the compliant core selected to produce a varying annular segment size of the compliant core and the non compliant layer selected to produce a constant annular segment size during rotation of the shaft in the loaded non-concentric configuration.
A tire for a roller, comprising:
- (a) a hub;
- (b) a first tire mounted on the hub for rotation with the hub, the first tire including:
- (i) a compliant core affixed to the hub for rotation with the hub;
- and
- (ii) a non compliant layer connected to the core for rotation with the core for rotation with the core.
