ABSTRACT:
A cylinder folding apparatus for a rotary printing press uses a collection and cutting cylinder in cooperation with a solid folding blade cylinder. A paper web train is cut into sections and is folded by transverse folding rollers. The point spur sets on the folding blade cylinder release signatures prior to commencement of the folding procedure. A brush roller is used to maintain contact between the signatures and the folding blade cylinder after release of the point spur set.
