ABSTRACT:
A shaft assembly having desirably stable dimensions for forming a precise sheet drive nip in a sheet handling machine such as a reproduction machine. The shaft assembly includes a shaft member having an outer surface, and a sheet drive-effecting member formed on the outer surface of their shaft member. The sheet drive-effecting member consists essentially of a first dimensionally stable molded material and has desired external dimensions. Importantly, the drive-effecting member has a thermoplastic elastomeric (TPE) material layer formed over the desired external dimensions for forming the precise sheet drive nip. The TPE material consists essentially of a thermoplastic vulcanizate (TPV) including a vulcanized rubber phase and a plastic material phase.
