Als junges Unternehmen, das in Norddeutschland zu Hause ist, haben wir uns auf innovative und hochwertige Industrieprodukte der Steuerungs- und Antriebstechnik sowie des Maschinen- und Anlagenbaus spezialisiert.
Unser Wissen und unsere Erfahrung sind mit unseren Anlagen bereits rund um den Globus in verschiedenen Erdteilen im Einsatz.
Neben den Kernbereichen unseres Unternehmens entwickeln wir auch stetig eigene Produkte und Verfahren, welche noch nicht am Markt erhältlich sind. Hiermit können wir immer wieder als „Ideenschmiede“ überzeugen und damit unsere Marktposition festigen und neue Absatzmöglichkeiten schaffen.
Aroma protection-/pressure-relief valves for maximum freshness protection for outgassing foods.
Aroma protection valves are designed for outgassing foods such as:
Roasted coffee beans and ground coffee, fresh yeast dough or sauerkraut (pickled cabbage) and other raw fruit and vegetable products.
Coffee packaging with pressure-relief aroma protection valves ensures freshness of beans and aroma for months. Accumulating gases can escape without the package inflating or even bursting. This way the quality and full aroma is kept even when stored for a longer period.
Freshly roasted coffee can be packaged directly, although it may still produce up to 6 liters of CO2 for one kilogram of beans. The valve opens as soon as the filling creates excessive pressure.
Aroma protection-/pressure-relief valves are manufactured and tested at our own production facility. They can be ultrasonically welded and heat-sealed to the packaging. The ultrasonic technology allows frequencies of >100 1/min. The valve, located inside, is visible from the outside by three small holes only and a circular welding seam which does not affect the packaging design.

Our inline padding systems are designed to be integrated in thermoforming machines. Directly after the tray production process, the pads are inserted automatically into the trays and fixed by ultransonic welding or hot melt on the bottom of the trays.
Through this the production process will be increased, several manufacturing processes are inapplicable and production area is saved. The handling is operated by scara robots or linear handling systems. The scara robot is an internal development is used in thermoforming machines, if the space is limited.
Generally the pad material is prepared on rolls and positioned in a unwinding station with a splicing unit. If the end of the roll is arrived, the ends of the active and reserve rolls will be welded and changed automatically without a stop of the machine.
A motor driven loop accumulator conveys the pads to the cutter without a tensile load. The pads will be cutted on the defined length and transferred to the vacuum belt. There the pads will be taken by the handling system, inserted into the trays and fixed by ultrasonic or hot melt.
Valve applicators respectively valves are always needed for applications with outgassing products: coffee, yeast dough and others.
Valve applicators are developed for welding valves into a film web by ultrasonic and can be integrated in existing or new packaging lines.
Our valve applicators are designed as a "stand alone" machine as a simple method to integrate in the packaging line. For optimising the packaging process on a high level, the valve applicators can be designed on customers demand directly into the packaging machine.
Valve applicators are mainly used in bag forming, filling and sealing machines, thermoforming machines and traysealer.
After more than 20 years experience, our new generationof non woven vacuum cleaner bag machines is able to produce the complete range of vacuum cleaner bags. Starting with basic standard vacuum cleaner bags up to complicated industrial vacuum cleaner bags up to 1400mm length and a cycle speed up to 800ms per bag, we achieve a perfect and constant product quality
For the first time it is possible to produce in several cycles an asymmetric bag with a fully automatic process.
From the automatic roll change up to the automatic banding and packaging a wide range of modules are available which can be chosen by demand and which can be completed to a fully automatic production line step by step.
