OPTIFOIL® doublers (AFD) feature ultramodern design. Their job is to double extremely thin aluminum foils just a few microns thick in preparation for the last rolling pass. Typical performances of an OPTIFOIL® Aluminium Foil Doubler:
• Foil width: ≤ 2,500 mm • Foil thickness: 2 x 10 – 2 x 100 (150) µm • Unwinding diameter: ≤ 2,300 mm • Winding diameter: ≤ 2,300 mm • Unwinding roll weight: ≤ 20,000 kg • Speed: ≤ 1,500 m/min
Ideally, an OPTIFOIL® separator is then used to separate the ultrathin foils after the final pass. For further processing some most modern types of OPTIFOIL® slitters present themselves.
