Abstract
The invention relates to a sheet stacking device on paper cross-cutting machines, consisting of a sheet supply and stacker device. A stacking device of this type comprises elements which retard the paper sheets supplied from a supply speed to zero and thus guide the sheets so that after being laid down they form a stack having a straight edge. The auxiliary elements required for the direct formation of the stack form the sheet stop board (8) and lateral guide plates (12, 13). In the case of a change of format, which generally necessitates a displacement of the sheet stop board (8) in the direction in which the sheets are supplied and of the lateral guide plates (12, 13) at right angles to the direction in which the sheets are supplied, in the case of an automatic format adjustment for the sheet stacking device, an exchange of the format-dependent lateral guide plates (12, 13) is no longer required. Therefore it was necessary to construct the lateral guide plates so that they are no longer exchanged when the format is changed, but that their effective length can be adapted to the respective longitudinal format of the sheets. This takes place due to the fact that each lateral guide plate (12, 13) is divided into at least two parts, so that with a large format, both parts form a long lateral guide plate (12, 13) and with a short format, a part (13) is raised by a drive (19), so that the sheet stop board (8) may pass under the raised lateral guide plate (13) close up to the lateral guide plate (12) which has remained in the working position.
