Patent ID: 7787814

Claim:
An edge wear reducing pressure roller, comprising: (a) a generally cylindrical elastomeric outer layer having a first end, a second end, a longitudinal axis, and a length for longitudinally supporting a copy sheet having a first edge and a second edge opposite to said first edge, said generally cylindrical elastomeric outer layer having a first position along said length for supporting said first edge of said copy sheet and a second position along said length for supporting said second edge of said copy sheet; and (b) a generally cylindrical core located within said generally cylindrical outer layer and having a first end, a second end, said longitudinal axis, and a length for supporting said generally cylindrical elastomeric outer layer, said generally cylindrical core including a first segment having a first diameter, and a second segment having a second diameter less than said first diameter for creating variation in thickness of said generally cylindrical elastomeric outer layer, said first segment supporting a first section of said generally cylindrical elastomeric outer layer having a generally uniform first thickness between said first position and said second position, said second segment being located at least directly below said first position for supporting said first edge of said copy sheet.
