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.
Claims9
A roller for a roller assembly as used in transporting a sheet material, through a nip formed between the roller and an opposed surface the roller comprising:
- a) a shaft;
- b) a first tire mounted to the shaft, the first tire including
- i) a compliant core fixed to the shaft for rotation with the shaft, the compliant core composed of a compressible open cell foam and
- ii) a non compliant outer layer fixed to the core for rotation with the core,
- c) the circumference and diameter of the non compliant outer layer remaining substantially constant as the outer layer rotates against an opposed surface to create the nip;
- and
- d) the compliant core allowing radial displacement of the outer layer relative to the shaft as the outer layer rotates against an opposed surface.
