ABSTRACT:
A folding assembly for book folding in web-fed rotary printing machines is disclosed. A take-over or transfer cylinder, which is capable of operating in either straight or collect run production, transfers signatures to an acceleration section which is run at a selected speed to deliver the signatures to a longitudinal folding device in a spaced array thereby allowing adequate time for the longitudinal folding device to perform a second longitudinal folding operation on the signatures. The speed of the acceleration section is varied by changing its gear drives.
