Rope Stretch Technology

RST stands for Rope Stretch Technology, an innovation that opens up a whole new world of possibilities when it comes to manufacturing biaxially stretched plastic film.

Unlike previous conventional chain track systems, the film is clamped by two ropes in the corresponding machine area and stretched. This new system significantly accelerates production, considerably improves energy efficiency, reduces maintenance and servicing costs and increases the service life of the machines.

Rope Stretch Technology was invented and developed by Wolfgang Pineggerin close cooperation with the K industries Group, Pinegger’s GloBra GmbHholds the applicable patents, and K industriesowns the exclusive global manufacturing licence as project partner. The Vienna University of Technology also made a major contribution to the development of RST.

After its launch at ArabPlast in January 2019 in Dubai generated great interest among the specialists in attendance, there were further opportunities to discover RST in New Delhi in March 2019, at CHINAPLAS in Guangzhou in May 2019 and at K 2019 in Düsseldorf in October.

Detailed discussions are currently ongoing with potential customers.


Using evaporation to create a natural fertiliser

Stringent new environmental regulations relating to handling the large quantities of fermentation residues produced during biogas generation are forcing biogas plant operators to act.

The K industries Group has teamed up with project partners to offer a smart solution called “KRETO”, a plant that can be docked directly onto an existing biogas plant. The mechanically pre-drained fermentation residue is transported via a reception hopper and using a bottom discharger and chain conveyor to a DFT© vapour/fluid dehumidifier, where it is heated to 120 °C to remove any remaining liquids. This process is followed by purification with a Teflon filter, condensation and compaction in a press. The heat necessary for dehumidifying comes from the waste heat produced by the CHP unit.

A reference plant is already operating trouble-free in the Verfahrenszentrum (Process Centre) in Reichstädt, near Dresden.
