Abstract
A high velocity air and stationary disturber cleaner for cleaning surfaces by drawing air under flexible film seals. A vacuum enclosed in a housing provides the suction force to draw the air under the seal, tangent to the surface to be cleaned, thus removing adhered particles. Disturbers are placed on the surface of the seals in contact with the surface to be cleaned to loosen particles to be removed. The brush density, the fiber length and a plastic film incorporated into the brush design are all ways to limit the amount of air flow through the bulk of the brushes for better cleaning efficiency.
Claims5
An apparatus, for cleaning particles from an imaging or a transfer surface, comprising:
- a housing;
- a flexible sheet, having one end attached to said housing and resiliently urging the other free end toward the surface;
- and
- vacuum means, connected to said housing, for generating air flow between the free end of said sheet and the surface in a direction substantially tangential to the surface, said sheet being adapted to control the air flow so the air flows at a velocity sufficient to disturb a layer of particles and remove particles from the surface at a boundary located between the particles and the surface.
An apparatus for cleaning particles from an imaging or transfer surface, comprising:
- a housing;
- a flexible sheet, having one end attached to said housing and the other free end of said sheet contacts the surface in a substantially tangential direction in the absence of air flow between the surface and said member;
- and
- vacuum means, connected to said housing, for generating air flow between the free end of said sheet and the surface in a direction substantially tangential to the surface, said sheet being adapted to control the air flow so the air flows at a velocity sufficient to disturb a layer of particles and remove particles from the surface at a boundary located between the particles and the surface.
