  • Patent number: 7845274
    Abstract: A web-fed printing press, in particular a newspaper printing press having at least two printing press subsystems, is disclosed. Each printing press subsystem has a printing unit comprised of several printing mechanisms, a web guidance unit for conveying printed and unprinted substrate webs and a turning bar unit having several turning bars. The printing press subsystems guide the printed substrate webs over at least one shared folding unit. At least one printing press subsystem is designed differently in comparison with the other or each other printing press subsystem such that substrate webs are printable with a different number of print pages in the printing press subsystems.

  • Publication number: 20090064882
    Abstract: An apparatus and method for forming cross folds in a web-fed printing press is disclosed. A folding unit has a longitudinal folding device and a cross folding device, which is arranged downstream from the longitudinal folding device, as seen in the transport direction of the printing substrate. The longitudinal folding device has one single former, where printing substrate webs entering the former as a strand are cut by a longitudinal cutting device assigned to the former or by at least one longitudinal cutting device assigned respectively to at least one printing substrate web of the strand by longitudinal cutting into partial webs, which exit the former as a strand, wherein the strand exiting the former can be divided downstream from the former and upstream from the cross folding device into at least three partial strands, and where a stitcher is assigned to at least one of the partial strands.
