Achenbach OPTIFOIL® Rewinder

Achenbach rewinder service for optimum and effective rewinding and trimming aluminum coils onto other spools. The aim is to either produce the material ready for sale or to prepare the coils for the downstream rolling process and thus to optimize it. Depending on the strip thickness and the production target, two design types are differentiated: the foil rewinder and the strip rewinder. Designed for rewinding diameters up to 2,100 mm at slitting speeds up to 600 m/min (foil rewinder) and 400 m/min (strip rewinder) as well as for coil weights up to 30,000 kg they are always tailored to the specific operation purpose. For each separator a holistic approach to perfectly synchronize mechanics, hydraulics, automation and drive technology in their complex interaction is applied.

The cloud-based platform Achenbach OPTILINK® opens the way to the overall system networking of the various value creation stages and therefore to the optimization of the entire production process.

Typical performances

  • Speed:
    Foil Rewinder: max. 600 m/min
    Strip Rewinder: max. 400 m/min
  • Rewinding diameter: up to 2,100 mm
  • Coil weight: max. 30,000 kg


When the coil has been fed to the rewinder via the automatic feeding device, the strip is guided over various rollers up to the recoiler, where the material is wound with the help of a belt wrapper thus ensuring the required strip run stabilisation. Depending on the respective design, an automatic threading device or feeding tables in combination with transfer tables are used to guarantee fast threading of the coils. An automatic cross cutting unit serves for cutting and disposing the inadequate strip nose to perfectly prepare the rewinding process. An ironing roller on the recoiler guarantees a high winding quality. The rewound strip is now ideally prepared for the subsequent rolling and further processing.
