Abstract
An apparatus for cleaning a rotatable cylindrical member such as a pressure roll of a fuser assembly includes an absorbent sheet having longitudinal sides joined at a seam and having a generally folded edge along a central longitudinal axis of the absorbent sheet. Rods disposed within the absorbent sheet support the absorbent sheet against the rotatable cylindrical member to clean the circumferential surface of the member as it rotates.
Claims21
Apparatus for cleaning a cylindrical member rotatable about a longitudinal axis, the apparatus comprising:
- an absorbent sheet having longitudinal sides joined together at a seam, a generally folded edge along a central longitudinal axis of the absorbent sheet, and inner and outer surfaces;
- a nonabsorbent barrier layer attached to the inner surface of the absorbent sheet;
- and
- means for supporting the outer surface of the absorbent sheet against the rotatable cylindrical member.
Apparatus for cleaning a cylindrical member rotatable about a longitudinal axis, the apparatus comprising:
- a seamless tube of absorbent felt having an inner surface and an outer surface;
- a non-absorbent barrier layer attached to the inner surface of the seamless tube;
- and
- means for supporting the outer surface of the tube against the rotatable cylindrical member.
A fuser apparatus, comprising:
- a fuser roll;
- a pressure roll having a peripheral surface which contacts the fuser roll;
- and
- means for cleaning the peripheral surface of the pressure roll, including an absorbent sheet having longitudinal sides joined together at a seam, a generally folded edge along a central longitudinal axis of the absorbent sheet, and inner and outer surfaces, a nonabsorbent barrier layer attached to the inner surface of the absorbent sheet, and means for supporting the outer surface of the absorbent sheet against the peripheral surface of the pressure roll.
A fuser apparatus, comprising:
- a fuser roll;
- a pressure roll having a peripheral surface which contacts the fuser roll;
- and
- means for cleaning the peripheral surface of the pressure roll, including a seamless tube of absorbent felt having an inner surface and an outer surface, a non-absorbent barrier layer attached to the inner surface of the seamless tube, and means for supporting the outer surface of the tube against the pressure roll.
