Kiefel: Emphasis on customer benefits at K 2004

Sophisticated process technology combined with automation dedicated to application requirements. The new generation of blown film extrusion lines under the KIRION® brand name which were first presented to the industry at the previous “K” in Düsseldorf in 2001 prove these very characteristics. Three years later, this system supplier from Worms has demonstrated that it has consistently followed the same path that it chose then. The company’s management team, Edgar Gandelheidt (Managing Director), Kurt Freye (Director of Sales Worldwide) and Dr Jochen Hennes (Technical Director) will present innovations at this year’s K’ Show, the international fair for plastics and rubber from 20th to 27th October, at stand C 42 in hall 17, that are characterized by enhanced user friendliness and by further rationalization of working procedures in the production of blown film.

Trade visitors in Düsseldorf will be able to observe a 3-layer line, showing the function of improved management of residual resins at the vacuum conveyor, as well as the most modern gravimetric metering units using variable range motors. Both of these elements of the modular extrusion line may be easily adjusted and controlled via the KIRION® C automation software. The new ultrasonic bubble control system is a new enhanced function integrated in the KIRION® C control system which allows width control to be significantly improved through an integration of the IBC control system and a servomotor-driven high speed fine adjustment unit in combination with the width measurement system.

But above all, it is in three additional modules that Kiefel Extrusion has achieved decisive progress that will be presented in October. First, industry experts will be impressed by improvements in cooling that contribute to increased output, better film clarity, and greater bubble stability. Second, AC vector direct drives for the extruders that finally make drive belts redundant, saves valuable installation space, and ensures easier maintenance, and finally its’ 9-layer die.

Kiefels’ engineers in Worms have succeeded with further developments that ensure the best possible film quality, such as a new haul-off in an extremely robust design, conceived in particular for large lay-flat widths up to 3.6 meters, and a new “cascade” width control system. A lay-flat package to produce film without bagging or necking is also now a part of the new KIRION® generation. This way Kiefel Extrusion can offer, for the first time, a solution for a significant increase in film flatness quality. And there are also new novelties to be expected in film collapsing. In detail, it means NC adjustment, use of brush rollers, and flattening in width while collapsing the bubble.

Regarding winders, the second largest business area for KIEFEL, the company confirms its technological leadership with a number of developments, such as a new refined winding shaft handling system that enables uncomplicated handling of rolls shafts as well as rolls, whether manual, semi-automatic, or fully automatic. Especially exciting after having invested many hours of development work is a new patented splicing device with which the direction of rotation can be reversed and winding made without the need for re-webbing.

For those visitors who are interested in learning more about further technical details of the KIRION® systems, KIEFEL is offering a shuttle between the fair and its factory in Worms every day during the K’ show. There, in the laboratory, a 7-layer line will be producing barrier film for one of their existing customers running EVOH and PA films, 24 hours around the clock. A radiometric thickness measurement system that is completely integrated in the KIRION® C will also be shown on this line.
