Abstract
An improved device and method for providing increased latitude of paper handling tires includes at least three elastomeric materials mounted on a shaft and divided into three or more torus-shaped sections of varied width. Combinations of EPDM, Silicone and Isoprene are examples of materials that can be used to make the paper handling tires.
Claims18
A reprographic device, comprising:
- a scanning member for scanning a document;
- an image processor for receives image data from said scanning member and processing it;
- a sheet feeder, said sheet feeder including a separation roll that feeds copy sheets to receive images thereon from said image processor, said separation roll including a composite of at least three elastomer materials with each of said at least three elastomer materials being positioned to contact the copy sheets during feeding;
- and
- at least one output tray for receiving the imaged copy sheets.

A sheet feeder system, comprising:
- a sheet support member for supporting a stack of sheets for feeding in a predetermined direction;
- and
- a shaft mounted separation roll that feeds sheets from the stack to receive images thereon from an image processor, and wherein said separation roll comprises a composite of at least three elastomer materials with each of said at least three elastomer materials being positioned to contact the sheets during feeding.
A method for improving the life and reliability of a paper handling tire, comprising:
- providing a shaft;
- providing at least three bands of elastomeric material;
- and
- mounting said at least three bands of elastomeric material on said shaft and adjacent to each other such that each of said three bands of elastomeric materials has a non-covered outer surface lengthwise of said shaft to form said paper handling tire.
