Abstract

In a device for stacking flat letters having a separating mechanism and a stacking mechanism between which the letters are stacked, the stacking mechanism capable of moving in the stacking direction along a stacking surface, and a transport path that is formed by endless vertical belts guided by way of rollers, between which belts the letters are conveyed from a loading station to the stacking mechanism, it is provided that the stacking surface has a horizontal concave curvature with respect to the side on which the transport path is located, and that the belts are deflected in the region of the transport path by a plurality of deflecting rollers that are disposed on a curve adapted to the curvature of the stacking surface in such a way that the transport path has a curvature adapted to that of the stacking surface, in the region of the transport path, the belts being disposed between the stacking surface and the deflecting rollers.
