3.4.1 Adjustment of foil unwind / rewind tension
Insert the print foil according the instruction in the Operation chapter.
The torque of foil unwind-and rewind mandrels are adjustable by means of the red hexagon pin.
The foil should run free of wrinkles respectively should not be stretched (especially at drum
section) over the whole run from roll to roll.
Increase of torque at unwind/rewind mandrel
Foil must not be stretched
Decrease of torque at unwind/rewind mandrel Foil must not have wrinkle
The factory adjustment covers a wide range of foil width which is the main factor for
the torque. Use of very narrow and very wide foil however may need a readjustment.
