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.
Claims13
A cross-fold module for a folding machine, having:
- a bearing installation on which a 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;
- wherein the delivery transport device is formed by at least one pair of continuous, driven belts, which belts are directly mutually opposite at least in a transport portion extending from the receiving portion to the delivery portion, and between which belts a portion of the folded product is sandwiched in the transport portion, and
- wherein a length of the transport portion is variable during the adjustment of the cross-fold knife and the pair of folding rollers.
