Contact SupplierThe Achenbach OPTIFOIL® doubler are complete machines for doubling aluminium foil with a modern design. Doubling the foil is used for the preparation of rolling extremely thin foil up to 5 µm. To achieve this gauge, the two doubled foils are rolled together in the final pass.
Typical performance figures of the Achenbach OPTIFOIL® doubler (AFD):
> Max. foil widths 2150 mm
> Foil gauge range 2 x 10 µm to 2 x 90 µm
> Max. running speeds 1400 m/min
> Max. unwind and rewind diameters 2100 mm
Individual customer requirements are perfectly met by a number of design, automation and process modules.
State of the Art System
> Constant foil guiding conditions during the complete doubling process; to achieve this, the position of the rewinder is linearly adjusted with increasing diameter
> Reproducible winding tightness
> Material threading device from both unwinders to the contact roller
> Automated coil and empty spool handling
> AC drive technology
