  • three standing or lying printed pages are arranged, so by using the longitudinal cutting device, the printed substrate sheet in a 1/3 width partial web (1 pressure side across the width having) and a 2/3-wide Part track (2 printed pages across the width having) to be cut longitudinally.
  • the two partial webs can be turned and aligned so that the 2/3-width partial web runs centered on the hopper tip on the former and the 1/3 width partial web runs with a side edge matching the hopper tip on the former.
  • a 3-sided product can be produced, in which between two contiguous, longitudinally folded printed pages (the 2/3-wide sub-web) a single printed page (the 1/3 -wide sub-web) is arranged.
  • the undivided printing material web can then be turned and aligned by means of a turning bar (possibly an additional turning bar) so that the undivided printing material runs onto the formwork hopper in the middle of its hopper tip.
  • a 2-page product can be produced, in which two contiguous printed pages are longitudinally folded in the middle.
  • the longitudinal cutting device can be moved parallel to the second web running direction, so that it can be set to predetermined, predetermined cutting positions corresponding to different web widths of the printing material web.
  • the longitudinal cutting device is movable transversely to the first web running direction or in the width of the printing material web to predetermined (for example stored in a machine control of the web press) cutting positions, whereby for different web widths always the o.g. 1/3-to-2/3-division of the printing substrate according to the invention can be achieved.
  • predetermined for example stored in a machine control of the web press

  • the first and the second turning bar can be variably adjusted in their position in the first web running direction such that, for example, in the production of a two-sided product, one of the two turning bars for turning and aligning the Undivided substrate web can be used. That is, preferably, the second turning bar is formed so long that it covers the maximum web width.
  • the first and the second turning bar are respectively movable individually or jointly parallel to the second web running direction or transversely to the first web running direction.
  • both turning bars depending on the printed product to be produced, can be moved further into the printing material web transversely to the first web running direction or driven out of it.
  • the second turning bar with its full length is driven into the printing material web (the first turning bar, which preferably has a length which covers a 1/3 wide partial web of a printing material web of maximum web width, remains out of operation or out of operation .) is driven out of the printing substrate), so that the undivided printing material runs into the middle of the hopper tip on the former.
  • the web press further comprises: a second printing line with at least one printing unit for printing a printing substrate and a longitudinal cutting device, which is arranged in the web run after the printing unit of the second printing section and which is set up so that the printing material web of the second printing line can be divided longitudinally into a 1/3-width partial path and a 2/3-width partial path, wherein the turning unit is arranged between the respective pressure units of the first and the second pressure path and the 1/3 width partial path and the 2/3 width Partial orbit of the second pressure line in a third web running direction, which runs parallel and opposite to the first web running direction, in the Turning unit are to be introduced, and wherein the turning unit has a third turning bar for the 1/3 width of part of the second printing line and a fourth turning bar for the 2/3-wide part of the second printing line, the third and the fourth turning bar are arranged parallel to each other , so that over this the 1/3-wide and 2/3-wide sub-web of the second printing section can be rotated by 90 degrees concurrently in
  • This embodiment of the web printing press according to the invention is a particularly cost-effective and practical solution, since two working in opposite directions print sections share a common turning unit, in which they introduce their respective printing material laterally, the printing material then turned 90 degrees are guided to respective former.
  • it is of course also conceivable to guide the printing material webs of the two printing sections on a common former. It is also conceivable to guide the two partial webs of a respective printing section to different formers or, if several printing units of a particular printing section to print multiple substrates to lead their respective partial webs on a common former or on different former.
