Foil waste exhausted to the foil waste removal system.

The principle of the Vinfoil Optima SF145MF

Continuous foil drive while both cylinder gaps are facing each other by use of the special engineered Direct Foil Drive rollers (before and after press nip). 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
DFD rollers
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.

Standard with:

MFU® (Multiple Foil Use), the best foil saving system in the world
DFD (Direct Foil Drive) to ensure precise synch between foil web and speed of press
ALUS++ (Automatic loading and unloading system) to optimize safety levels and ensure fast change over times
VIFOP (Vinfoil Intelligent Foil Optimizing Programme) online software to calculate optimal foil use
FU (Foil Unit) where foil is unwinded
FWRS (Foil Waste Removal System) for non-stop production and waste removal by air transport
FSC (Foil Shaft Changer) to prepare a job during production to save time

Description of individual Optima sections

• 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.
• The use of MFU® can reduce the cold-foil consumption up to 85 %
• 2 MFU® decks with horizontally movable guiding rods for lateral adjustment of the foil webs position • MFU® Decks can be moved in vertical direction for circumferential adjustment of the foil web position
• Motorized foil infeed system from Foil Unit to the MFU® section

• With the DFD (Direct Foil Drive) rolls, the foil web speed is controlled by a servo motor. The 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
• Two DFD rolls are installed. One before and one after the press nip

• 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
• Minimum construction height

With this on-line software, foil consumption is calculated by just uploading the pdf with the layer of the cold foil.
Very useful for management and prepress.
