Claims
- 1. A sheet guide device for a sheet-processing machine in which sheets of printing material are transported along a sheet transport direction, the sheet guide device comprising:an adjustably mounted first guide element formed with a supporting face inclined transversely with respect to the sheet transport direction for supporting first side edges of the sheets; a second guide element with a supporting face inclined transversely with respect to the sheet transport direction for supporting second side edges of the sheets opposite the first side edges; a third guide element disposed between said first guide element and said second guide element; and an adjusting device operatively connected with said first guide element and including a motor for adjusting said first guide element.
- 2. The sheet guide device according to claim 1, which comprises a screw mechanism establishing a drive connection between said motor and said first guide element.
- 3. The sheet guide device according to claim 2, wherein said screw mechanism comprises a threaded spindle arranged axially parallel to a further threaded spindle.
- 4. The sheet guide device according to claim 1, which comprises a flexible drive mechanism forming a drive connection from said motor to said first guide element.
- 5. The sheet guide device according to claim 1, wherein said supporting face is curved transversely with respect to the sheet transport direction.
- 6. The sheet guide device according to claim 1, wherein said first guide element includes a plurality of mutually spaced-apart supports together covering said supporting face.
- 7. The sheet guide device according to claim 1, wherein said third guide element is formed with pressurized-air openings.
- 8. The sheet guide device according to claim 1, wherein said third guide element is adjustably mounted toward a sheet transport device transporting the sheets of printing material, and away from the transport device, and including a motorized adjusting device for adjusting said third guide element.
- 9. The sheet guide device according to claim 1, wherein said first guide element is adjustably mounted on a sheet transport device of the sheet-processing machine circulating about and transporting the sheets of printing material.
- 10. The sheet guide device according to claim 1, wherein said first guide element is adjustably mounted adjacent a sheet transport device on a frame of the sheet-processing machine circulating about and transporting the sheets.
- 11. The sheet guide device according to claim 1, wherein said second guide element is adjustably mounted for adjustment by said motor.
- 12. The sheet guide device according to claim 1, which comprises a further motor, and wherein said second guide element is adjustably mounted for adjustment by said further motor.
- 13. In combination with a machine processing sheets of printing material in which the sheets are transported along a sheet transport direction, a sheet guide device comprising:an adjustably mounted first guide element formed with a supporting face inclined transversely with respect to the sheet transport direction for supporting first side edges of the sheets; a second guide element with a supporting face inclined transversely with respect to the sheet transport direction for supporting second side edges of the sheets opposite the first side edges; a third guide element disposed between said first guide element and said second guide element; and an adjusting device operatively connected with said first guide element and including a motor for adjusting said first guide element.
- 14. In combination with a sheet-fed rotary printing machine in which sheets of printing material are transported along a sheet transport direction, a sheet guide device comprising:an adjustably mounted first guide element formed with a supporting face inclined transversely with respect to the sheet transport direction for supporting first side edges of the sheets; a second guide element with a supporting face inclined transversely with respect to the sheet transport direction for supporting second side edges of the sheets opposite the first side edges; a third guide element disposed between said first guide element and said second guide element; and an adjusting device operatively connected with said first guide element and including a motor for adjusting said first guide element.
