  • Patent number: 11772927
    Abstract: The cross-fold module for a folding machine comprises a cross-fold knife which is movable in a reciprocating manner in a folding-knife movement direction, and a pair of folding rollers which form a folding roller gap in which a sheet that previously was fed in the feeding direction is creased for folding by the cross-fold knife. A delivery transport device for the folded product receives the folded product in a receiving portion close to an outlet of the folding roller gap and transports the folded product to a delivery portion. At least the cross-fold knife and the pair of folding rollers are adjustable horizontally, perpendicular to the folding-knife movement direction and perpendicular to the feeding direction.
