Definitions

  • the present invention relates to an apparatus for performing a printed web between the mutually parked cylinders of a shutdown Printing unit of a web-fed rotary printing press.
  • a first reason is e.g. B. that the blanket cylinder is inclined relative to the vertical are arranged such that one adjoins through the centers of the two Blanket cylinder extending axis through an inclination angle of z. B. 10 ° to 15 ° is inclined towards the vertical as the web moves horizontally.
  • the inclined position of the cylinder has the advantage that the web does not only apply the cylinder a narrow line, but to stabilize it by a certain amount Peripheral portion of each blanket cylinder is wound, so the better To obtain the clamping point.
  • the inclination of the cylinders creates a consistent one Peeling or peeling off the web from the blanket cylinders.
  • a second reason why the blanket cylinders are not easily separated from each other is that in most web-fed rotary presses in which the Web printed by two corresponding blanket cylinders on both sides one of the blanket cylinders is normally stored in the frame in the printing unit is to serve as a reference point and only the other of the cylinders is moved when it is desired to separate the cylinders from one another. It is also due to the Construction of the mechanical drive mechanism for stopping the Blanket cylinders from each other are generally not possible, the cylinders more than approx. 2 mm to 4 mm apart.
  • a third reason why the blanket cylinders are not easily separated from each other is that the running web is subject to strong vibrations and flutter is subject. Even if there is a gap of approx. 4 mm wide, contact-free passage theoretically allows the track through the inclined cylinders, which are set apart from each other, the freshly printed and still wet web would inevitably cover the surface of the Touch cylinder and the print quality would decrease dramatically and the Risk of web break increased.
  • the production of high quality printed products is usually the Ink flow from the ink fountain to the plate cylinders of each printing unit interrupted, the printing plates on the plate cylinders by unimaged plates replaced and the plate and blanket cylinders then at normal web speed driven, with the dampening system switched on and the web with the respective Blanket cylinder is in contact.
  • the web can be z.
  • B. air-blown blowpipes or turning bars around the shutdown (s) Printing unit (s) are redirected.
  • guiding or bypassing has printed web around the shutdown printing units the disadvantage that for each new Print job in which the shutdown printing units are switched on again , the endless web must be drawn into the respective printing unit.
  • Another technical way of guiding the web between each other parked cylinders of a shutdown printing unit consists of the web via fixed, upstream and downstream of a stopped To guide printing rollers or discs located (so-called “grater rollers").
  • grater rollers can cause unacceptable damage not only on the wet surface of a printed web, but also on the surface of a cause unprinted web in an offset printing press.
  • guide rollers significantly reduce the risk of a web break increase.
  • leadership roles are usually only found in newspaper printing presses Low quality printed products are used.
  • GB 1 461 572 describes an apparatus for assisting the leading end of a moving flexible web which comprises two arcuate arrays of air nozzles mounted above and below the web path which converge towards the inlet nip of cutting rollers of a subsequent cutting area.
  • the air streams coming out of the air nozzles are directed onto the web path and are preferably concentrated on the inlet gap mentioned.
  • This device is only for pulling a flexible web through the cylinder column of a printing press or an auxiliary device, for. B. a cutting device, a folder or a non-operated slitter.
  • DE-OS 28 22 137 discloses a device similar to the description of the UK patent, which serves as a pulling-in and guiding aid when pulling the front end of a running, flexible web into the inlet gap between two cutting cylinders of a subsequent cutting area.
  • This device comprises two air nozzles through which air is blown towards the inlet nip, centering the leading edge of the paper web and preventing the web from moving sideways.
  • FR-A-2 519 298 is a web-fed rotary printing press with one between two Printing units of the printing press arranged blowing device known that the top and the underside of the substrate web over perpendicular to the web or against the Blowing air is arranged on both sides of the web with blowing air, to eliminate vibrations of the web and thereby a doubling in the to avoid subsequent printing units.
  • the embodiments of the present invention enable a quick and easy change of print jobs, especially a change from multi-color printing on single-color printing, since it is not necessary to run the web over idle printing units to lead away.
  • a new print job the shutdown of a previously used printing unit in simple Caused in such a way that the blowing air supplied through air nozzles is switched on and the corresponding cylinders of the respective printing unit from each other.
  • the decrease in Transverse vibrations also stabilize the orbit over a longer section away, e.g. B. between three printing units or coating units, so that the Distance by which the blanket or coating cylinders for a non-contact Passing the printed web must be separated from each other is reduced.
  • Another advantage of the device according to the invention is given in that no incorrect register settings, such as those used for the Use of floating guide devices guiding the web without lubrication, e.g. B. blowpipes, in the deflection of the web around a decommissioned printing unit occur are avoided. It was also found that a new time adjustment the printing units to each other (retiming) is almost not necessary when a printing unit is taken out of the railway path, because it has surprisingly been shown that the path on which the web or substrate is using the device according to the invention moved through a stopped printing unit, approximately corresponds to the path that the web during normal printing or Coating process.
  • An additional advantage in using the present invention is that it because of a deflection of the web over a stopped printing unit none of the smear-proof devices that let the web float, such as air pipes incorrect register setting comes. In addition, there is almost no renewal Time setting required if a printing unit is excluded from the web path , since it has been found that the path on which the web or the substrate moved by a stopped printing unit, the path during normal printing or coating is very similar.
  • Fig. 1 are a first plate cylinder 2 and a corresponding first printing or Blanket cylinder 4 of a printing unit for printing a first side 6 through the printing unit web 8 shown.
  • a second plate cylinder 10 and a corresponding second printing or blanket cylinder 12 are on the second side 14 of the web 8 so that both sides of the web are printed simultaneously can.
  • the cylinders 2, 4, 10 and 12 are in the direction of Vertical inclined by about 10 ° to 15 °, so that the running web 8 with respect to the Cylinders 4 and 12 have a certain amount of wrap and one consistent peeling or peeling effect of the web from the blanket cylinders 4, 12 generates what stabilizes the web and a better nip point to control the Creates tension.
  • the mechanical shutdown mechanism for separating the Cylinders 4 and 12 from each other can be a known eccentric mechanism, for example the distance between the cylinders 4 and 12 is normally at most limited to approx. 2 mm to 4 mm.
  • one of the blanket cylinders is usually fixed in the frame in the side frame and serves as a reference point. So can the path is not straight through the gap between the two cylinders 4 and 12 move through without touching the surfaces of cylinders 4 and 12.

  • the blowing air 18 coming from the first and second blowing devices 16 and 26 and 28 forms an air flow between the web 8 and the surface of each first and second cylinders 4 and 12. This air flow prevents the current Track 8 touches the cylinders 4 and 12 and thus prevents lubrication of the printed or coated web 8.
