  • the guide system is configured with at least one deflecting element in such a way that the film is fed a second time from the guide system after a first pass through the at least one printing unit to this printing unit in the conveying direction of the film, so that coating of the film that passes through the first pass through the film Printing unit could not be removed from the film could with the film in conveying direction so passes to the printing unit, that the remaining on the first pass on the film coating on the second transfer to the medium is transferable for 100% utilization of the coating on the film, film cost savings without waste due Pressure gap and better and easier handling of the films.
  • the film transfer inline-foiler according to the invention can optionally be operated in the same way as the prior art film transfer in-line-foils for greater flexibility in production by not feeding the film to the printing unit a second time.
  • the guide system is provided with two deflecting elements, so that the film, which is narrower than the medium to which the coating is transferred from the film, optionally at the first passage z. B. runs on the right side of the medium and the second pass on the left side of the medium to transfer the coating of the film side by side on the medium or both passages made on the same side.
  • the deflection elements are formed as rods, wherein the Surfaces of the deflecting elements are profiled along its longitudinal axis in order to suppress displacements of the film when sliding the film over the deflecting elements in the axial direction of the deflecting elements.
  • the profiles of the surfaces may be concave shapes, flaky profiles on the surface, or combinations thereof.
  • the deflecting elements can also be designed as rollers.
  • the deflecting elements are preferably pivotally mounted centrally on at least one carrier to the conveying direction of the film, so that z. B. is preferably adjustable by parallel pivoting over the amount of pivoting, as far as the film is phase-shifted relative to the first conveyor run at the second conveyor run.
  • two deflecting elements spaced apart from one another are each set at 45 ° to the direction of conveyance of the film, so that the film is deflected by 90 ° at each deflecting element and is offset parallel to the conveying path before the two after passing through two deflecting elements deflecting elements.
  • the deflecting elements are profiled on its outer circumference along its longitudinal axis, z.
  • the film is half as wide as one in the at least one Maximum transmission of printing unit, so that the width of the printing unit is maximized.
  • the deflecting elements are displaceably mounted on the carrier for improved adjustment.
  • the phase shift is equal to the length of the transmission during the first passage through the at least one printing unit, so that the entry of the film in the printing unit at the second passage begins at the point at which the transfer of the coating from the Film would be terminated on the first pass, so that in parallel juxtaposed films, the coating in the first pass begins with the coating of the second passage.
  • the deflection bars on the carrier are also displaceable in the direction of the longitudinal axis of the carrier and preferably transversely displaceable to the longitudinal axis of the carrier for better adjustability of the phase shift and / or to different widths of the film.
  • an edge monitoring device is provided in the control system, which is mounted on the guide system and through which the film extends to control the parallel offset of the film by means of the motor-driven holder by rotating and / or moving the deflecting elements relative to each other and to the carrier, on which these are stored.
