Abstract

A buckle folder machine includes two or three folder pockets and several folding rollers mounted in a folding block which can be detached from the machine frame. The sheets are fed to the folding block via transport devices along an input plane in the direction of travel of the paper and delivered along an output plane in the same direction. The input plane and output plane are situated on substantially the same plane. The folding rollers and machine pockets are arranged in the folding block in such a way that the sheet input and sheet output are also situated in the area of this common plane in line with the position in which the folding block is mounted inside the machine frame. All folding rollers are connected to each other in the folding block via coupling gear wheels positioned on either end of each folding roller. The drive mechanism is located in the machine frame and in the area of the folding block has a drive gear positioned in same machine frame which in a first mounting position of the folding block meshes with one of the coupling gear wheels. One of the folding rollers has a driven gear at its other end which meshes with the drive gear in a second mounting position of the folding block in which said block is inserted into the machine frame in such a way that it is turned 180.degree. in relation to its first mounting position around an imaginary axis extending parallel in the direction of travel of the paper.
