Polishing Stacks

Perfect Finish of Flat Films and Sheets

It makes a big difference if you produce a half finished film product or a sheet as finished product. We realize individual configurations for the optimal adaptation of our Polishing Stack to the desired surface quality and thickness tolerances of the film.

The first-class quality of our Polishing Stacks allows a reliable production at highest level, designed for many years of operation. The handling and operating of the esde Polishing Stack is our own design and is persuasive in its flexibility to most different tasks.


Depending upon the required loads the Polishing Stack is equipped with a pneumatic or hydraulic roll locking force. Cooling rolls and haul-off are driven by high-dynamic synchronous servo-drive motors. The drives are exactly inertia tuned and are synchronized with each other.


The rolls in our Polishing Stacks always run evenly and produce constant, excellent film and sheet quality. The principle of roll deflection compensation (BLK) facilitates the manufacture of an extremely constant film thickness. Because of its stabilized core the BLK roll equidistantly adapts to the deflection of the standard cooling roll and, the tolerance of the film thickness is therefore kept at a minimum.

The secret of our Polishing Stacks

For the production of high quality film the temperature distribution on the contact surface of the film has to be kept constant. Conventional technologies regulated the roll temperature by a punctual feed of cooling water - thus causing relatively high temperature deviations.


The amount of needed cooling water in our Polishing Stacks is infinitely adapted to the heat requirements during the manufacturing process. In addition the continuous thermal flow of the roller water is supported by a progressively tapered helix.


In this way we achieve, on the contact surfaces of the film, a temperature distribution accuracy of +/- 1°C: A highly effective system with low consumption of energy and water!

Here are the most important points for our esde Polishing Stacks

  • Vertical or horizontal Polishing Stacks for all sizes
  • Rolls with matt or high gloss surfaces
  • Highly true running accuracy for an optimal film finish
  • Individual configurations adapted to varied requirements
  • Cooling roll with deflection compensation (BLK) for low tolerances of the film thickness
