Abstract

A folding apparatus for rotary printing presses uses at least a single stage speed reducing device between a collection cylinder and a folding blade cylinder to reduce the speed of travel of signatures before they are cross-folded. The reduction in the speed of travel of the signatures eliminates damage to the signatures during their cross folding while allowing the printing press to operate at a high rate of speed.
