  • the pressure elements used in each case can be cyclically switched off the film drive roller 70 or reduced in their Anstell
  • the very fast clock circuits for the clock drive 71 are derived from an angle signal of the sheet-fed press, wherein the sequences of the control are repeated over each revolution of a counter-pressure cylinder 4 and a press roller 3 respectively.
  • the relevant machine angles for a passage of a cylinder channel 22, 80 for each known printing unit of the sheet-fed printing machine 1, 2, 50 are automatically output from the machine control. For this reason, the relevant machine angles for the timing of the film transport of the transfer film 5 are present in the used as a coating unit 2 printing unit.
  • the channel timing can be performed with fixed predetermined angle values for braking and acceleration of the transfer film web 5, since the passage angles of the channel edges 81.1, 81.2 are predetermined by the machine construction.
  • the safety switching distances E1, E2 depending on the area coverage of the Drucken 83 can optionally be switched on, if, for example, to be coated with metal foil Drucksujet more or less close to the sheet edge.
  • the braking ramp B and the acceleration ramp C can be influenced via control parameters.
  • the mechanical properties of the transfer film 5 play a role, since the thin film is always kept smooth and on the other hand, neither the film itself nor the transfer coating must tear. Usually, standardized values for different types of film are used here, which can be present as a characteristic table in the device.
