Achenbach OPTIFOIL® doublers consist mainly of two coil deposits for material access, a cart, two unwinding stands, a roller bridge with a material feed device, a spray unit with suction for separating oil application, a shear or razor trimming device, a winder and a reel cart for transporting the empty reel from the unwinding stations to the winder. Each doubler features very short material transport paths.

A variety of useful automation and process engineering options allows the system to be easily adapted to individual customer requirements. Examples of this include the simultaneous transport of two coils for unwinding or different coil and reel handling systems; these options can be added anytime.
