Abstract
A folding device is provided which produces folded printed products from an incoming web of printed material. The folding device has a mechanism for automatically converting the folding device from a configuration that forms a single transverse fold to a configuration that forms a second transverse fold parallel to the first fold. The conversion mechanism has a set of movable belts wound partially around a first folding cylinder and partially around a second folding cylinder. It also has a device for moving the set of movable belts to a first position, where the set of movable belts is wound partially around the first folding cylinder downstream of a plane P passing through the axes of the first and second folding cylinders, for forming a single transverse fold and to a second position, where the set of movable belts is wound only partially around the second folding cylinder downstream of the plane P passing through the axes of the first and second folding cylinders, for forming a second transverse fold parallel to the first fold.
