Claims
- 1. A device for aligning the edge of a single sheet document comprising:
- surface means defining a path along which said single sheet is to be conveyed, said path including a contoured portion which causes said sheet to assume a contoured configuration as it moves along said contoured portion of said path;
- reversible transport means for conveying a sheet along said path;
- resilient conical-shaped elements adjacent said contoured portion of said path, said conical-shaped elements positioned to engage said sheet as it moves along said contoured portion of said path; and
- control means for repeatedly reversing said transport means when said conical elements engage said sheet to cause said sheet to be urged by said conical elements to one side of said path.
- 2. A device as defined in claim 1 wherein said contoured portion of said path is defined by a semi cylindrical surface which is symmetrical about an axis.
- 3. A device as defined in claim 2 wherein said conical elements are symmetrical about an axis which is generally aligned with the axis of said semi cylindrical surface.
- 4. A device as defined in claim 3 wherein said semi cylindrical surface is concave and the outer peripheral edges of said conical elements are concentric with said surface.
- 5. A device as defined in claim 1 wherein said transport means is an endless belt having side-by-side linear belt runs connected by a round belt run.
- 6. A device as defined in claim 5 wherein said belt runs are parallel.
- 7. A device as defined in claim 1 further comprising sensing means for sensing when said sheet is aligned with said one side of said path.
- 8. A device for aligning an edge of a single sheet document comprising:
- a first planar surface;
- a second planar surface spaced from and opposing said first planar surface;
- a concave, arcuate surface at the ends of said first and second planar surfaces, said arcuate surface intersecting said first planar surface and said second planar surface to connect said first planar surface to said second planar surface, said first and second planar surfaces and said arcuate surface defining a sheet document transport path;
- a reversible conveyor belt having a first belt run disposed relative to said first planar surface so as to be able to convey at least one sheet document therealong, a second belt run disposed relative to said second planar surface so as to be able to convey a sheet document therealong and a round belt run disposed within said arcuate surface to drive a sheet document therealong; and
- at least one resilient conical element adjacent said arcuate surface, said conical element positioned to engage a sheet document moving along said arcuate surface.
- 9. A device as defined in claim 8 further comprising reversible drive means for driving said conveyor belt.
- 10. A device as defined in claim 9 further comprising control means for repeatedly reversing said conveyor belt to move a sheet document over said at least one conical element.
- 11. A device as defined in claim 10 further comprising sensing means for sensing when a sheet document has moved to one side of said path.
- 12. A device as defined in claim 11 wherein said first planar surface is parallel to said second planar surface.
- 13. A device as defined in claim 8 wherein said arcuate surface is cylindrical in shape and said conical element has a circular peripheral edge which is concentric to said arcuate surface.
- 14. A device for aligning the edge of a single sheet document comprising:
- a plurality of surfaces defining a path along which said single sheet is to be conveyed, said path including a contoured portion which causes said sheet to assume a contoured configuration as it moves along said contoured portion of said path;
- a reversible transport drive assembly for conveying a sheet along said path;
- resilient conical-shaped elements adjacent said contoured portion of said path, said conical-shaped elements positioned to engage said sheet as it moves along said contoured portion of said path; and
- a control unit for repeatedly reversing said transport when said conical elements engage said sheet to cause said sheet to be urged by said conical elements to one side of said path.
