ABSTRACT:
A folding apparatus for rotary roller printing presses, having at least one collecting or crosswise folder, positioned behind which there is at least one sword folder composed of a folding sword interacting with a pair of folding cylinders, the folded material being conveyed to the sword folder via a belt guide having upper and lower belts and, in the region of the folding sword, passing positioned limit stops for the folded material. The belt guide has at least two strands positioned one behind the other and being driven at opposingly stepped speeds, with the faster-running strand on the collecting or crosswise folder side, having a run-out groove opening wedge-shapedly, beyond which least one locating stop moving at the speed of the slower-running strand, on the sword folder side, is positioned, its path at least partly overlapping with the feeding-in region of the equally fast belt guide strand.
