A combination is provided on a feeder table of a sheet-processing machine, which includes a front lay member cyclically swivelable about an axis, in accordance with a sheet-conveying cycle, and a leading-edge stop for effecting an alignment of paper sheets, the leading-edge stop being disposed on and swivelable with the front lay member out of an alignment position, into a rest position and back into the alignment position, the leading-edge stop including an adjustment device for adjustably fastening the 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 the front lay member in the alignment position of the front lay member for engaging and disengaging the alignment of the paper sheets by the leading-edge stop.
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.
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.
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.
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.
