Unwinding system for protective foil

The new double unwinding station is a solution for the steady unwinding of protective foil for wrapped profiles. It makes sure that the thermoplastic foil will be unwound independently from its own adhesiveness and cover the entire area that it has to protect. 

Information

Its task is to protect the wrapping material optimally. However, the protective foil itself is also thermoplastic, thin, easy to deform and self-adhesive.The different qualities of the various adhesives are a common problem that lead to irregular unwinding. Often, this causes overstretching of the protective foil. Later, when the protective foil tightens, it does not completely cover the area that has to be protected - paving the way for unpleasant claims.
 
To prevent this problem and to increase quality as well as efficiency, Duespohl has developed a double unwinding station for protective foil. This new component makes sure that the force that is required to peel off the foil from the reel will be independent from the tape's own adhesiveness. This way, we guarantee a regular unwinding process and constantly low tension. So what's the result? The foil will neither be overstretched and nor will it re-tighten after few days.

Highlights

  • steady unwinding process, independent from diameter and adhesiveness of the protective foil
  • increased process safety: protective foil will always cover the entire wrapped area
  • quality assurance and prevention of claims
  • reel changing during on-going production
  • also available as retrofit to optimise existing lines
