    Abstract: BACKUP ROLL FOR HEATED FUSER SYSTEM An improved backup roll for use in the heated fuser system of electrostatic copy machines wherein the fuser system employs a fuser roll couple comprised of a heated fuser roll in pressure contact with the backup roll. In construction, the backup roll includes an aluminum core member with a coating of polyurethane reinforced fluroinated ethylene propylene on its surface. The coating has heat transfer characteristics similar to the copy sheets fed through the couple so as to withdraw heat from the heated fuser roll, along each zone where it may make direct contact with it, at substantially the same rate as the copy sheets withdraw heat. The coating also has a thickness whereby the heat transferred to each zone during contact with the fuser roll is quickly transferred to the aluminum core before that zone again contacts the fuser roll.

    Abstract: Thermoplastic powder images delivered in succession from the transfer station of a copy machine or the equivalent station of another electrostatic printer at a high rate of speed are fixed to a support sheet by heat and pressure in a substantially slower moving fusing roll couple. This differential speed enables the operation of the fusing roll couple at lower temperatures and pressures to make practical the use of an internally heated fusing roll having a deformable surface. The speed of the fusing roll couple is perferably selected to substantially eliminate the space between successively delivered copies such that the rolls of the roll couple need not be separated between successive copies. A conveyor that transports copies to the roll couple is preferably driven with a programmed speed to match the speed at which a copy is generated and to alternately match the slower speed of the fusing roll couple as the copy is introduced thereto.
