Abstract
This is a photoconductor and dispenser assembly and system. The photoconductor is in a tubular form so as to accept a tubular formed dispenser within its hollow portion. The dispenser will coat within this hollow portion a uniform coating of an acoustical dampening material. This material will dull any sound produced by the photoconductive marking system. The assembly is the tube having in its hollow portion this dispenser. The dispenser fits tightly but movably within the hollow portion.
Claims18
A photoconductor (PR) and dispenser assembly comprising:
- a PR having a tubular form with an outer photoconductor's surface and a hollow inner portion.
- said dispenser configured to tightly slide into said PR inner surface, said dispenser having a rear end portion being a material inlet and at a front end portion a material outlet,
- said material outlet configured to apply a substantially circumferentially uniform coating of a sound or acoustic dampening material to a PR inner surface,
- said dispenser configured to be totally removable from said hollow inner portion of said PR after said coating of a sound dampening material is completed.
A coating dispenser system useful in coating an interior of a xerographic drum or tube, said dispenser comprising:
- a tubular shaped housing having a central core in an interior portion and a material flow path extending around said core, said path extending through substantially an entire length of said housing,
- one end of said housing comprising a coating material inlet opening, and an opposite end of said housing comprising a coating material dispensing section with a material dispensing gap,
- said material inlet opening configured to receive an acoustic dampening coating material, said material dispensing section configured to apply a said acoustic dampening material as a uniform coating in an inside portion of said drum, and
- a source of said acoustic dampening material in flow connection with said coating material inlet opening.
