Optima® SF80MF

“The savings of an Infigo combined with the compact size of the Micro”

VINFOIL OPTIMA® SF80 MF system for offset printing machines in the size 700-800 mm

Highlights Vinfoil Optima® SF80 MF

  • Optimal Foil Saving feature: MFU®
  • Perfect foil web tension and positioning at any speed achieved by Vinfoil’s DFD technique
  • Changeover time under 6 minutes with ALUS+ and FSC
  • Speed of up to 18.000 sheets/hour achievable (also with MFU®)
  • Very low building height and the access to the printing units is optimal
  • Changing the reels takes place at ground level, which ensures a very easy and safe operation
  • The sensitive metallic layer of the cold foil is never getting in contact with any part of the Vinfoil Optima® SF80 MF

The principle of the Vinfoil Optima® SF80 MF

  • Continuous foil drive while both cylinder gaps are facing each other by use of the special engineered Direct Foil Drive roller. This Vinfoil technology ensures a perfect synchronisation of circumference speed of the press with the cold foil web.
  • Web tension is regulated by software which is feeding data to the following Vinfoil’s technologies (patent applied):
    • Servo motion control systems with torque control
    • Magnetic powder clutches
    • DFD roller
    • FT locking shafts
  • MFU® is redirecting the cold foil web back into the printing nip after transferring parts of the metallic layer for the first time. With this technology a foil web can be used up to 3 times to generate optimal utilization of the cold foil reel.
  • It is not necessary to stop and to restart the foil web with every turn of the cylinder like in systems using indexing.
  • Multi reel without limitation in quantity of foil cores

Direct Foil Drive (DFD)

  • With the DFD (Direct Foil Drive)l, the foil web speed is controlled by a servo motor – This motor is controlled by an encoder integrated into the printing press to ensure a very precise synchronization of the foil web with the speed of the printing press
  • Electronically adjustable web tension

Dimensions:

The DFD is integrated in the MFU® frame. For the dimensions see MFU®

  • Automatic unloading and loading, to ensure fast change over times
  • Changing the reels takes place at ground level, which ensures a very easy and safe operation
  • Integrated safety with the foil module
  • Loading and unloading two rolls at the same time
  • Minimum building height
