Dynamic change of gang run

Abstract

A method operates a facility, which serves for the continuous production of multiple gang runs for forming individual signatures or signature packs from which type-specific print products are made in a downstream print further processing machine. An endless web is the basis for the formation of these multiple gang runs. The endless web, in the non-folded state, is imparted complementary handling by facility-internal means according to the following criteria: i) in a 2-gang run, the individual signatures or the folded signature packs are only deflected in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station; and ii) in a 3 or 4-gang run, the individual signatures or the folded signature packs are additionally folded in a second longitudinal air folding station disposed downstream of the first longitudinal air folding station.
