Division profile
Systems to manufacture blown film have formed part of ALPINE's product range since 1955.
The reliability of these film blowing lines is well known, just as are the long years of experience we have had in the design and manufacture of such complex production equipment.
Our three testing centres - in Augsburg, USA and Japan - are equipped with state-of-the-art machines and components, and are used for both customer and development trials. Test series using the laboratory equipment can be carried out under as-real conditions so that the results fully reflect Alpine's capabilities.

Globally, blown film lines have become a mass product, for which there is high demand in diverse areas of application. The increased variety of products, as well as the growing production quantities go hand in hand with increasing quality requirements. The Reifenhäuser product program for blown film extrusion lines meets all these demands, thanks to the innovative components and overall concept.
Areas of application
The range of applications of blown films produced on Reifenhäuser lines
is huge. Antistatic films, stretch films and protective films are used in the automotive and electronics industries, for example. In the field of industrial packaging, shrink hood films, stretch hood films and heavy duty sack film are manufactured on Reifenhäuser lines. A remarkably wide product range include films for the consumer goods industry, fine shrink films, pallet wrap films, furthermore it includes laminating and adhesive films, as well as barrier films. Lines for agricultural products, such as crop forcing, cover and silage films, as well as building protection films, have been a Reifenhäuser speciality for many years.

Calenders for rubber
RODOLFO COMERIO desings and manufactures calendering lines for rubber, where the calender is the main machine in the line and the rolls, 4, "S" configuration represent the heart of the machine.
RODOLFO COMERIO calenders, furthermore, can be enriched by the most advanced automatic control and adjustment systems for thickness and profile of the film, by means of rolls shifting, roll-bending, cross-axis and preloading. These mechanisms, furthermore, can be integrated with electronics, in order to offer calendering process control by gathering and automatically adjusting all production parameters. For the production of tires, in the end, the differnet types of plant or configurations is determined by the differnet rubberizing technologies :
- Textile cord rubberizing lines
- Steel cord rubberizing lines
- Combined textile and steel cord rubberizing lines
- Rubber sheets production lines

Twin Screw Extruder
Machine Characteristics
* The longer screw with the newest double conical structure and variable pitch improve the output by over 30%.
* The compact distribution gearbox with the thrust bearings of the famous brand makes the convenient assembly and/or disassembly.
* The hardened gear surface of the gearbox guarantees the high loading capacity and long service life.
* The extruder and feeder are driven by the DC motor. The using of British EUROTHERM DC speed controller achieves the synchronization of the extruder, feeder and haul-off machine, which makes the operation more convenient.
* The Japanese PKG meter ensures precise temperature controlling.
* The main electric components are from the overseas suppliers or domestic joint ventures.
* The melt pressure and temperature transducers allow the obvious inspection of the melt and easy operation.
* The Twin Screw Extruder are mainly used for the processing of the soft/hard PVC pipes, PVC profiles, PVC cables, PVC transparent bottles as well as the other polyolefin products, especially the direct processing of the plastic/powder materials.

By constantly developing new, more modern and powerful extruders throughout the many decades of the Reifenhäuser success story, Reifenhäuser has built the foundation that ensured that the wide scope of plastics products could be established on the market. Regardless of which raw material is subjected to the thermal shaping process, regardless of which product exits the end of the production line after the process is complete: Without the appropriate extruder at the heart of the extrusion line, nothing is possible.

The corotating technology can also be applied for pipes production when one or more pipe layers are made of filled/reinforced materials, just like for the following reference applications:
> Extrusion of pipes for heating systems where the core layer is made of PP reinforced with glass fibres
> Extrusion of soil stacks/pipes where the core layer has a high percentages of mineral fillers for deadening purposes.
> Extrusion of generic purposes pipes using low cost materials filled with mineral fillers
