Abstract:
1. A device for folding a flexible material web comprising: at least one pair of counterrotating layering rollers, between which the material web may be fed to a folding location, said laying rollers being part of a laying carriage which is movable over the folding length of the material web with reversible orientation; said laying carriage including two transport bands which at least rotate around the laying rollers, the material web being transportable at least partially guided between the transport bands, and the speed of the material web having the same absolute value as the speed of the transport bands; said folding position having a height which is adjustable in the movement direction and the folding position exerting a pressure on a layer of the material web or on a material web stack formed by multiple folded layers of the material web; a counterpressure able to be implemented via the section of the transport band extending parallel to the folding location and/or to the uppermost folded layer of the material web, or a counterpressure able to be implemented via the lower section of a holding-down band extending parallel to the folding location and/or to the uppermost folded layer of the material web.
