Polishing Stacks

Perfect Finish for extruded Flat Films and Sheets

The first-class quality of our polishing stacks allows a reliable production on the highest level and guarantees many years of service life.


esde Polishing Stacks are responsible for the perfect surface finish of flat films and sheets, optionally also for coating and laminating. We realize individual designs for the optimal adaptation of our polishing stacks to the desired surfaces and uniformity of the film thickness.


The technology of our Polishing Stacks

In the esde Polishing Stack the equal temperature distribution on the entire contact surface of the film guarantees high-quality film production.


In esde Polishing Stacks the amount of cooling water is stepless adjusted to the heat requirements in the manufacturing process. Aditionally the uniform heat flow in the roll water is supported by a progressively tapered conducting helix. This way we achieve an accuracy of +/- 1°C in temperature distribution on the contact surface of the film: Highly effective, with low energy and water consumption!


Depending on the necessary linear loads the polishing stack is build with pneumatic or hydraulic locking devices. Cooling rolls and haul-off unit are driven by servo-gear-motors, synchronized with one another and optimized in its mass inertia.


The rolls on our Polishing Stacks turn smoothly and evenly, thus ensuring a consistent quality of films and sheets. The principle of the polishing roll with compensation of the deflection (BLK) allows the manufacture of extremely uniform film thickness.

Due to its stabilized core the BLK-polishing roll adapts equidistantly to the curve of the standard cooling roll. This ensures that the tolerances of the film thickness can be kept to a minimum.


Features and Advantages of esde Polishing Stacks

  • Individual design tailored to diverse requirements
  • Constant high quality of film and sheets
  • Vertical or horizontal roll arrangement, also 45° arrangement is possible
  • Rolls driven by low backlash planetary gears
  • High accuracy of true running for optimal film finish
  • Pneumatical or hydraulical roll locking force
  • The base frame is electrically motivated (optional also with two axles) to ease maintenance and cleaning procedures.
  • roller surfaces in chromium plated, matted or embossed
  • rolls with very equal temperature distribution on the entire contact surface
  • uniform heat flow in the roll water supported by progressively tapered conducting helix
  • stepless adjustment to the target value of the cooling water temperature

Laminating and Coating

In front of the Polishing stack an unwinding unit can be integrated into the extrusion line. Whether the film web should be laminated or coated or material should be applied, we always keep an easy and secure handling in view.


Operating Concept

The operating surface of our Polishing Stacks has a user-friendly and clear structure. We use a comfortable Touch-Screen Technology with logical user guidance. The training effort for the operators is minimal as no programming knowledge is required.


The operating elements are positioned on the extruder and if needed on further line components, positioning as desired by the customer.


All the relevant processing data can easily be read and adjusted. The control is upgradable with production data acquisition, an intersection to the Desktop PC and the possibility of remote control by our electrical engineers.
