ABSTRACT:
A sheet delivery apparatus includes a cutter cylinder, a cutter reception cylinder, and a conveyor provided downstream of the cylinders. The cutter cylinder and the cutter reception cylinder cooperatively cut a paper web so as to yield sheets of predetermined size. The sheets are delivered by the conveyor. A dampening unit is provided upstream of a region where the cutter cylinder and the cutter reception cylinder closely face each other and in the vicinity of the paper web so as to dampen the paper web such that the surface of the paper web which will face the cutter cylinder is dampened to a greater extent than is the other surface.
