Abstract
Abstract In the changing of the dimensions of sheets of paper to be stacked by a paper stacking apparatus including a conveying station, adjustable upper tapes moving about reflection rollers, separating shoes, ejector rolls, separating plates and stopper boards, the improvement which comprises displacing the upper tapes along with their deflection rollers, the separating shoes, the ejector rolls, and the separating plates all together transversely to the paper path. This is effected by providing a rod which connects the upper-tape deflection rollers, a separating shoe, ejector rolls, and a separating plate whereby they will all be transversely displaced together.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
254 words
A device for stacking sheets of paper for transporting to a stacking station in at least two rows, comprising lower and upper means of conveyance including belts wrapped around deflection rollers and which extend over the stacking station, said station composed of several elements including a separating shoe, a separating plate for each row of paper, said separating plate positioned between each path that the sheets are transported along and acting on the longitudinal edges of the sheets, and stops positioned at the end of the transport path, wherein the upper means of conveyance and the separating shoe and the separating plate that act on the sheets and the stops are adjustable to a particular sheet format, characterized in that the means of conveyance, the separating shoe and the separating plate that act on the longitudinal edges of the sheets, and the stops assigned to each row of sheets are all mounted on first guide rails that extend across the direction in which the sheets are transported in such a way that the sheet size can be adjusted across said direction of transport and in that, the separating shoe, the separating plate, and stops are positioned one after another in a row along the direction of transport and, the means of conveyance are coupled to a common drag shaft that extends along the direction of transport in such way that it entrains the separating shoe and the separating plate, and the stops when the means of conveyance are adjusted across the direction of transport.
Claim 2
Independent Claim

A device for stacking sheets of paper for transporting to a stacking station in at least two rows, comprising lower and upper means of conveyance including belts wrapped around deflection rollers and which extend over the stacking station, said station composed of several elements including a separating shoe, a separating plate for each row of paper, said separating plate positioned between each path that the sheets are transported along and acting on the longitudinal edges of the sheets, and stops positioned at the end of the transport path, wherein the upper means of conveyance and the separating shoe and the separating plate that act on the sheets and the stops are adjustable to a particular sheet format, characterized in that the means of conveyance, the separating shoe and the separating plate that act on the longitudinal edges of the sheets, and the stops assigned to each row of sheets are all mounted on first guide rails that extend across the direction in which the sheets are transported in such a way that the sheet size can be adjusted across said direction of transport and in that, the separating shoe, the separating plate, and stops are positioned one after another in a row along the direction of transport and, the means of conveyance are coupled to a common drag shaft that extends along the direction of transport in such way that it entrains the separating shoe and the separating plate, and the stops when the means of conveyance are adjusted across the direction of transport.
Claim 3
Dependent Claim
33 words
A device according to claim 1, wherein the upper means of conveyance are belts stretched around deflection rollers and the drag shaft acts as a spacer for pillow blocks of the deflection rollers.
Claim 4
Dependent Claim
30 words
A device according to claim 1 wherein the drag shaft is mounted in such a way that it is rotatable and is coupled to at least one transverse-adjustment drive mechanism.
Claim 5
Dependent Claim
26 words
A device according to claim 1 wherein the stops and/or the separating plate are adjustable along the direction of transport in relation to the drag shaft.
Claim 6
Dependent Claim
39 words
A device according to claim 1 wherein the first guide rails that extend across the direction of transport are laterally mounted on second guide rails that extend along the direction of transport at the side of the transport path.
Claim 7
Dependent Claim
32 words
A device according to claim 5 wherein the means of conveyance have a drive mechanism that operates in conjunction with only the second guide rails for adjustments in the direction of transport.
