high performance bubble coolingsmart lip maximizerThe increase of profitability of our high performance lines – that was the starting point for our R&D de-partment when they developed the MAXIMIZER, an optimally adjusted product range for outer bubble cooling. The development team consisting of R&D engineers, designers and sales people was able not only to increase the output capacity of the lines by up to 50% but also to positively influence the quality of the films.

Smart Lip Maximizer LN – Efficient cooling concept for “long neck” production for HDPE and LDPE films.

Smart Lip Maximizer – Infinitely variable height adjustable cooling ring for improvement of output and film quality.

Smart Lip DUAL – Variable dual cooling ring in stack design, infinitely variable height adjustment for impro-vement of the throughput capacity and film strength.

KEC Kuhne Extrusion Control – Operator friendly, clear and central automation controls the production and assures a continuous high film quality.

Kuhne Smart Change – Automatic format change at the push of a button.

Kuhne’s modular principle offers the following options:Extruders

With smooth or grooved feed sections in diameters from 25 to 150 mm

Die heads

- Mono die heads with diameters from 50 mm to 600 mm

- 3 layer die heads with diameters from 100 mm to 900 mm

- 5, 7,9 and 11 layer die heads with diameters from 150 mm to 750 mm

Quenching systems

High efficiency IBC and Cooling rings in different designs

Film take off units

- Reversing take off units with air supported turning bars from 1000 to 3600 mm

- Stationary take off units for a working width from 1000 to 3600 mm

Film winders

- Contact/centre/gap winder with one or two winding positions for a layflat width between 1000 mm and 3600 mm

- Contact winders with one or two winding positions for a layflat width between 1000 and 3600 mm

For the film winders we offer winding shafts and roll handling systems up to fully automatic solutions.
