Claims
- 1. A system for decurling a sheet having a length and a width which is being advanced in a predetermined orientation with one of said length or said width oriented parallel to a direction of movement along a predetermined path within a printing machine, comprising:
- means for generating a flow of room ambient air;
- means for directing the flow of room ambient air onto the sheet;
- a decurler adapted to apply mechanical force to the sheet after the flow of room ambient air has been directed onto the sheet by said directing means;
- means for rotating the sheet to advance the sheet to the decurler in an orientation with the other of said length or said width oriented parallel to the direction of movement along the predetermined path.
- 2. The decurling system of claim 1 wherein said rotating means is disposed at a position along the predetermined path before said directing means.
- 3. The decurling system of claim 2 further comprising means for advancing the sheet from the decurler to the sheet rotator.
- 4. The decurling system of claim 3 further comprising a gate for selectively advancing the sheet to an output location or the advancing means.
- 5. The decurling system of claim 1 wherein said rotating means comprises a baffle disposed at a position forty-five degrees from the direction of the predetermined path.
- 6. The decurling system of claim 1, wherein said generating means comprises a fan having an intake port positioned to receive ambient air directly from a location outside of the printing machine.
- 7. The decurling system of claim 1, wherein said directing means comprises a duct positioned to receive the flow of room ambient air from said generating means.
- 8. The decurling system of claim 7, wherein said duct comprises a plate having an aperture defined therein.
- 9. The decurling system of claim 8, wherein said plate is positioned substantially adjacent the sheet path.
- 10. The decurling system of claim 9, wherein said directing means directs the flow of room ambient air onto the sheet through the aperture defined in said plate.
- 11. A system for decurling a sheet having a length and a width which is being advanced in a predetermined orientation with one of said length or said width oriented parallel to a direction of movement along a predetermined path within a printing machine, comprising:
- means for generating and directing a flow of room ambient air onto the sheet; and
- a decurler adapted to apply mechanical force to the sheet after the flow of room ambient air has been directed onto the sheet by said generating and directing means;
- means for rotating the sheet to advance the sheet to the decurler in an orientation with the other of said length or said width oriented parallel to the direction of movement along the predetermined path.
- 12. The decurling system of claim 11 wherein said rotating means is disposed at a position along the predetermined path before said generating and directing means.
- 13. The decurling system of claim 12 further comprising means for advancing the sheet from the decurler to the sheet rotator.
- 14. The decurling system of claim 13 further comprising a gate for selectively advancing the sheet to an output location or the generating and advancing means.
- 15. The decurling system of claim 11 wherein said rotating means comprises a baffle disposed at a position forty-five degrees from the direction of the predetermined path.
- 16. The decurling system of claim 11, wherein said generating and directing means comprises a fan having an intake port positioned to receive ambient air directly from a location outside of the printing machine.
- 17. The decurling system of claim 11, wherein said generating and directing means comprises a duct positioned to receive the flow of room ambient air.
- 18. The decurling system of claim 17, wherein said duct comprises a plate having an aperture therein.
- 19. The decurling system of claim 18, wherein said plate is positioned substantially adjacent to the sheet path.
- 20. The decurling system of claim 19, wherein said plate is positioned such that the flow of room ambient air flows through the aperture therein onto the sheet.
