Abstract (en)
[origin: WO2013113411A1] The invention relates to a device for a web-fed rotary printing press for processing one or more printed webs, comprising a former, a strand leaving said former, a cross-cutter device arranged downstream of the former in the strand course, as well as a strand path formed between the former and the cross-cutter device via at least one guiding element. On at least one longitudinal former section which extends in the transport direction, and in the region of both its right-hand and its left-hand former flanks, said former comprises blast-air openings which are fluidically-connected to a fluid line that conducts a fluid which is at a higher pressure than the ambient pressure. At least one suction opening, facing the web strand to be folded, is arranged on said former between a left-hand and a right-hand flank-side section which comprises blast-air openings, and/or upstream of blast-air openings that are provided in a projection region, and/or a suction opening of a nozzle engaging in the folded strand is provided in the strand path downstream of said former. The suction opening in question is fluidically-connected to a fluid line that conducts a fluid which is at a lower pressure than the ambient pressure.
