A cross-fold module for a folding machine, comprising: a bearing installation on which a preferably pre-folded sheet being infed in a feeding direction at least partially comes to bear; a stop member against which a leading edge of the infed sheet comes to abut; a cross-fold knife, which is arranged above the bearing installation, extends in the feeding direction and is movable in a reciprocating manner in a folding-knife movement direction perpendicular to the feeding direction; a pair of folding rollers, which are arranged below the bearing installation and opposite the cross-fold knife, and which form a folding roller gap in which a sheet is creased by the cross-fold knife for folding, thus forming a folded product; and a delivery transport device for the folded product, which is configured to receive the folded product in a receiving portion close to an outlet of the folding roller gap and to transport the folded product to a delivery portion in a direction transverse to the feeding direction and transverse to the folding-knife movement direction; wherein the cross-fold knife and the pair of folding rollers are adjustable in a direction transverse to the feeding direction and transverse to the folding-knife movement direction; characterized in that the delivery transport device is formed by at least one pair of continuous, driven belts which are directly mutually opposite at least in a transport portion extending from the receiving portion to the delivery portion, and which receive a portion of the folded product in the transport portion between them, and the length of the transport portion is variable when the cross-fold knife and the pair of folding rollers are adjusted. a bearing installation on which a preferably pre-folded sheet being infed in a feeding direction at least partially comes to bear; a stop member against which a leading edge of the infed sheet comes to abut; a cross-fold knife, which is arranged above the bearing installation, extends in the feeding direction and is movable in a reciprocating manner in a folding-knife movement direction perpendicular to the feeding direction; a pair of folding rollers, which are arranged below the bearing installation and opposite the cross-fold knife, and which form a folding roller gap in which a sheet is creased by the cross-fold knife for folding, thus forming a folded product; and a delivery transport device for the folded product, which is configured to receive the folded product in a receiving portion close to an outlet of the folding roller gap and to transport the folded product to a delivery portion in a direction transverse to the feeding direction and transverse to the folding-knife movement direction; wherein the cross-fold knife and the pair of folding rollers are adjustable in a direction transverse to the feeding direction and transverse to the folding-knife movement direction; characterized in that the delivery transport device is formed by at least one pair of continuous, driven belts which are directly mutually opposite at least in a transport portion extending from the receiving portion to the delivery portion, and which receive a portion of the folded product in the transport portion between them, and the length of the transport portion is variable when the cross-fold knife and the pair of folding rollers are adjusted.
