Photoconductive belt assembly

Claim 2

A belt assembly, including: a sub-belt; a photoconductive belt arranged to be secured releasably to one surface of said sub-belt; a strip having one surface thereof attached to said sub-belt with the other surface thereof having an adhesive so as to enable the leading and trailing edges of said photoconductive belt to be attached thereto; and means for supporting movably said sub-belt, said supporting means defining a path about which said sub-belt moves in unison with said photoconductive belt.

Claim 3

An assembly as recited in claim 1, wherein opposed side marginal regions of said sub-belt extend beyond opposed side marginal regions of said photoconductive belt.

Claim 4

An assembly as recited in claims 2 or 1, wherein the leading and trailing edges of said sub-belt are attached to one another defining a first closed path and the leading and trailing edges of said photoconductive belt are attached to one another defining a second closed path with the second path defined by said photoconductive belt being smaller than the first path defined by said sub-belt so as to stretch said photoconductive belt producing forces securing said photoconductive belt to said sub-belt.

Claim 5

An assembly as recited in claim 1, wherein said supporting means includes: a plurality of spaced posts having said sub-belt entrained about the outer peripheries thereof; and a pair of opposed, spaced edge guides secured to one of said posts and arranged to contact the side edge of said sub-belt when said sub-belt deviates laterally from the preferred path of movement thereof so as to restore said sub-belt to the preferred path.

Claim 6

An electrophotographic printing machine of the type having a photoconductive belt assembly moving about a preferred path through a plurality of processing stations, wherein the improvement includes: a sub-belt; a photoconductive belt arranged to be secured releasably to one surface of said sub-belt; a strip having one surface thereof attached to said sub-belt with the other surface thereof having an adhesive so as to enable the leading and trailing edges of said photoconductive belt to be attached thereto; and means for supporting movably said sub-belt, said supporting means defining a path about which said sub-belt moves in unison with said photoconductive belt.

Claim 7

An electrophotographic printing machine of the type having a photoconductive belt assembly moving about a preferred path through a plurality of processing stations, wherein the improvement includes: a sub-belt; a photoconductive belt arranged to be secured releasably to one surface of said sub-belt; a strip having one surface thereof attached to said sub-belt with the other surface thereof having an adhesive so as to enable the leading and trailing edges of said photoconductive belt to be attached thereto; and means for supporting movably said sub-belt, said supporting means defining a path about which said sub-belt moves in unison with said photoconductive belt.

Claim 8

A printing machine as recited in claim 5, wherein opposed side marginal regions of said sub-belt extend beyond the opposed side marginal regions of said photoconductive belt.

Claim 9

A printing machine as recited in claims 4 or 5, wherein the leading and trailing edges of said sub-belt are attached to one another defining a first closed path and the leading and trailing edges of said photoconductive belt are attached to one another defining a second closed path with the second closed path being smaller than the first closed path so as to stretch photoconductive belt producing forces securing said photoconductive belt to said sub-belt.

Claim 10

A printing machine as recited in claim 5, wherein said supporting means includes: a plurality of spaced posts having said sub-belt entrained about the outer peripheries thereof; and a pair of opposed, spaced edge guides secured to one of said posts and arranged to contact a side edge of said sub-belt when said sub-belt deviates laterally from the preferred path to restore said sub-belt to the preferred path.
