  • the avoidance of tooth flank changes is a measure to increase the print quality.
  • the plate or form cylinder is equipped with a Druckbeistellvorraum.
  • Schmitz rings are arranged on both sides of the plate and blanket cylinders. These bearer rings are hardened steel rings which roll against each other under mutual pressure of the cylinders (pressure pressure) and with usually the same outside diameters as friction wheel gears.
  • protective measures In order to ensure safe operation of a printing or varnishing machine, protective measures must be implemented on the control side for all hazards caused by drives of the processing machine. This applies both to the main drive with gear train as well as each independently driven by the main drive drive a self-powered device, especially in driven by single drive plate or forme cylinders.
  • basic protective measures or safety requirements in particular measures for a safe shutdown of the drive, measures against an unexpected start of the drive, measures to maintain maximum speeds of the drive, measures to comply with maximum distances of the drive and measures to maintain a correct direction of rotation of the same. If one of the safety measures fails, in particular the failure of a single drive or an angle encoder, the processing machine must be shut down.
  • the object of the invention is to provide a method of the type mentioned above, according to which in such a processing machine with at least one individually driven, a printing plate-bearing cylinder in the presence of a fault, a production of the printing or Lackier joses is still guaranteed.
  • a first advantage of the invention is based on the fact that directly in the presence of a fault, in particular in case of failure of a single drive or an angle encoder, a synchronous operation between the driven by a main drive and a gear train cylinders or rollers of a printing unit or coating unit and the respective own motor means Single-drive driven plate / forme cylinder is specified in the printing / painting operation.
  • the main drive can be formed by several in the gear train feeding drives.
  • a solution is shown, after the plate cylinder of a Printing unit or the forme cylinder of a coating unit in case of failure of a single drive or an angle encoder again Passer can be positioned just for the production pressure.
  • a third advantage is that at least parts for the preparation of the print run in emergency mode can be automated.
  • single drive of the forme cylinder in the coating unit also includes an own motor driven (single drive) drive of a forme cylinder in a flexographic printing unit.
  • printing form includes a paint form or a flexographic printing form.
  • the sheet-fed rotary printing machine is shown for example with a feeder 4, five offset printing units 1, a coating unit 2 and a boom 5.
  • Each offset printing unit 1 has in a known manner an inking unit 12 with inking rollers, a cylinder 10 carrying a printing plate, here as a plate cylinder 10, and a blanket cylinder 8. If necessary, each plate cylinder 10 is associated with a dampening unit.
  • the coating unit 2 has in a known manner a metering device 11 for the medium to be processed (paint, ink), preferably a chambered doctor blade with assigned, screened applicator roll, as well as a printing plate (paint form, flexographic printing) carrying cylinder 9, here as a forme cylinder 9, on.
  • Plate cylinder 10 and forme cylinder 9 each carry at least one printing plate and are in contact with the inking rollers of the inking unit 12 or the applicator roller of the metering device 11.
  • each offset printing or coating unit 1, 2 is designed as a printing cylinder sheet guiding cylinder 6 with the respective blanket cylinder 8 and form cylinder 9 in functional connection, wherein in the first offset printing unit 1 formed as a printing cylinder sheet guiding cylinder 6 a collision drum is arranged as a sheet guiding cylinder 6.
