Paper & plastic slitters

The keyslits line is designed to slit and rewind finished reels for various applications from consumer rolls to web fed printing presses.

The keyslits have the flexibility and versatility to adapt to a wide range of materials and formats, namely: papers, auto-adhesive papers and films, boards and films, tissue paper, plain, printed, coated or laminated.

These rewinders are able to add inline modules as printing or embossing units, giving an added value according the client´s business needs.

General features:

  • Accuracy: The Keyslit design and performance offers the ultimate in both finished roll quality and accuracy.
  • Roll density control: The wide variety of Keyslits´s winding modes and the operation efficiency ensure the highest roll density control.
  • Slit separation: Guaranteed slit separation is a key feature of all the Keyslit models.
  • Latest AC drive technology: Keyslit incorporates the latest in AC drive technology to ensure consistency and reliability of operation as well as low maintenance needs.
