Abstract
Abstract n apparatus in which a cleaning material is transported into contact with particles adhering to a flexible member (10) in a cleaning zone. The flexible member (10) is maintained at a pre-selected tension by means (16). During cleaning, the flexible member (10) is deflected by means (58) fortransport- ing the cleaning material into contact with the particles adhering to the flexible member (10) to form an extended cleaning zone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
85 words
An apparatus (56) for removing particles from a flexible member (10), characterised by means (58), positioned closely adjacent to the flexible member (10) defining a cleaning zone therebetween, for transporting a cleaning material into contact with the particles adhering to the flexible member, and means (16) for maintaining the flexible member (10) at a pre-selected tension of sufficient magnitude so that the flexible member (10) deflects about said transporting means (5B) to form an extended cleaning zone between said transporting means and the flexible member.
Claim 2
Independent Claim
85 words
An apparatus (56) for removing particles from a flexible member (10), characterised by means (58), positioned closely adjacent to the flexible member (10) defining a cleaning zone therebetween, for transporting a cleaning material into contact with the particles adhering to the flexible member, and means (16) for maintaining the flexible member (10) at a pre-selected tension of sufficient magnitude so that the flexible member (10) deflects about said transporting means (5B) to form an extended cleaning zone between said transporting means and the flexible member.
Claim 3
Dependent Claim
13 words
Apparatus according to claim 1, wherein the flexible member (10) is a belt.
Claim 4
Dependent Claim
53 words
Apparatus according to claim 2, wherein said transporting means (58) includes a tubular member (76), means for attracting the cleaning material to said tubular member (76) and means (98) for rotating said tubular member to transport the cleaning material into contact with the particles adhering to said belt (10) in the cleaning zone.
Claim 5
Dependent Claim
25 words
Apparatus according to claim 3, wherein said belt (10) deflects about said tubular member (76) in an arc ranging from about 10° to about 40°.
Claim 6
Dependent Claim
26 words
Apparatus according to claim 3 or 4, wherein said maintaining means (16) tensions said belt (10) to a magnitude of about 0.1 kilograms per linear centimeter.
Claim 7
Dependent Claim
13 words
Apparatus according to any preceding claim, wherein the cleaning material includes magnetic particles.
Claim 8
Dependent Claim
25 words
Apparatus according to claim 6, wherein said attracting means (74) includes an elongated magnetic member disposed interiorally of and spaced from said tubular member (76).
Claim 9
Dependent Claim
34 words
Apparatus according to claim 7, further including means (84) for electrically biasing said tubular member (76) to a polarity and magnitude sufficient to attract the particles from said belt (10) to the cleaning material.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 8, further including means (88) for scavenging the particles from the cleaning material adhering to said tubular member (76).
Claim 11
Dependent Claim
30 words
An electrophotographic printing machine of the type having residual particles adhering to a flexible photoconductive member, including apparatus for removing particles from the photoconductive member according to any preceding claim.
