Claims
- 1. On a feeder table of a sheet-processing machine, the combination comprising a front lay member cyclically swivelable about an axis, in accordance with a sheet-conveying cycle, and leading-edge stops for effecting an alignment of paper sheets, said leading-edge stops being disposed on and swivelable with said front lay member out of an alignment position, into a rest position and back into said alignment position, each of said leading-edge stops being adjustment means for adjustably fastening said respective leading-edge stop in a respective position thereof in a conveying and counter to a conveying direction, respectively, of the paper sheets with respect to said front lay member in said alignment position of said front lay member, said adjustment means including a sheet abutting surface formed on each of said leading-edge stops, each of said leading-edge stops having an axially symmetric construction and being mounted in said front lay member so as to be rotatable about the axis of symmetry thereof, and said leading-edge stops and said front lay member including corresponding deflecting elements for producing a translatory displacement of said respective leading-edge stop in direction of said axis due to rotation about said axis.
- 2. The combination according to claim 1, wherein said front lay member is formed with a stop for limiting an adjustment path of each of said leading-edge stops with respect to said front lay member in said direction counter to said conveying direction, said leading-edge stops, in said alignment position of said front lay member being in said engaged position for aligning the leading edge of the sheet, when said leading-edge stops are in engagement with said respective stop formed on said front lay member.
- 3. The combination according to claim 1, wherein said axially symmetrical leading-edge stops have a peripheral surface formed with regions for introducing force for effecting a rotational adjustment.
- 4. The combination according to claim 1, wherein said axially symmetrical leading-edge stops have a peripheral surface formed with static friction surface regions.
- 5. The combination according to claim 4, wherein said static friction surface regions are selected from the group consisting of knurled and rubber-covered surface regions.
- 6. The combination according to claim 1, wherein said adjustment means include screws formed with an external thread corresponding to an internal thread formed in said front lay member, and said leading-edge stops are respective heads of said screws.
- 7. The combination according to claim 1, wherein said adjustment means include a pin, one of said adjustment means and said front lay member being formed with an axial cam, and the other of said adjustment means and said front lay member having a cam-follower element corresponding to said axial cam.
- 8. The combination according to claim 1, wherein said adjustment means includes a nut formed with an internal thread, and including an external screw thread formed on said front lay member, said internal thread corresponding to said external screw thread.
- 9. The combination according to claim 1, wherein said leading-edge stop is formed with profiling for engagement by a tool.
- 10. The combination according to claim 1, wherein said leading-edge stops are formed with means for axial position determination.
- 11. On a feeder table of a sheet-processing machine, the combination comprising a front lay member cyclically swivelable about an axis, in accordance with a sheet-conveying cycle, and leading-edge stops for effecting an alignment of paper sheets, said leading-edge stops being disposed on and swivelable with said front lay member out of an alignment position, into a rest position and back into said alignment position, each of said leading-edge stops being adjustment means for adjustably fastening said respective leading-edge stop in a respective position thereof in a conveying and counter to a conveying direction, respectively, of the paper sheets with respect to said front lay member in said alignment position of said front lay member, said adjustment means including a sheet abutting surface formed on each of said leading-edge stops, and means for guiding over said leading-edge stops a respective paper sheet pulled from the feeder table, said guiding means including at least one sheet-guiding roller.
- 12. On a feeder table of a sheet-processing machine, the combination comprising a front lay member cyclically swivelable about an axis, in accordance with a sheet-conveying cycle, and leading-edge stops for effecting an alignment of paper sheets, said leading-edge stops being disposed on and swivelable with said front lay member out of an alignment position, into a rest position and back into said alignment position, each of said leading-edge stops being adjustment means for adjustably fastening said respective leading-edge stop in a respective position thereof in a conveying and counter to a conveying direction, respectively, of the paper sheets with respect to said front lay member in said alignment position of said front lay member, said adjustment means including a sheet abutting surface formed on each of said leading-edge stops, and a cover lay fastened on said front lay member in vicinity of said leading-edge stops, said cover lay being formed with a sheet-guiding surface for guiding over said leading-edge stops a respective paper sheet pulled from the feeder table, said cover lay being formed with a pass-through opening providing access for adjusting said leading-edge stops.
- 13. On a feeder table of a sheet-processing machine, the combination comprising a front lay member cyclically swivelable about an axis, in accordance with a sheet-conveying cycle, and leading-edge stops for effecting an alignment of paper sheets, said leading-edge stops being disposed on and swivelable with said front lay member out of an alignment position, into a rest position and back into said alignment position, each of said leading-edge stops being adjustment means for adjustable fastening said respective leading-edge stop in a respective position thereof in a conveying and counter to a conveying direction, respectively, of the paper sheets with respect to said front lay member in said alignment position of said front lay member, said adjustment means including a sheet abutting surface formed on each of said leading-edge stops, and each of said leading-edge stops is a sliding element, and including corresponding deflecting elements on said front lay member and on said leading-edge stop for producing a translatorial displacement component of said leading-edge stop in the sheet conveying direction when said leading edge stops are slid substantially transversely to the sheet conveying direction.
