![]() Whether it’s in the fruit, vegetables, frozen foods, animal feed or gardening sector, customer demands for high-quality, functional and environmentally friendly flexible packaging are rising constantly. The components then automatically recognized one another.” “We assembled the components of the new web guiding according to the plug & play principle. Schubert attests to “considerably increased user-friendliness” in the intuitive menu navigation of the controller. “This ensures that the webs are fed centrally through the extruder.” The intuitive color LC touch display of the ekr 500 digital Unit Touch, with the innovative ekr commander, shows the web position, the sensor covers and the position of the actuator with easily readable graphics and symbols. “When changing web widths, the sensor positioner automatically moves the sensors to the web edge and positions the webs according to the measurement results provided by the sensors,” says Schubert, commending how easy it is to set up the system. Both the FVG POS 100, developed specially for wide webs, and the ekr 500 digital Unit Touch functioned flawlessly from the very beginning. After all, the 24-hour operation of this extruder with a comparatively high ambient temperature was seen as the ultimate test for the new technology. BST eltromat installed a switch for us, so that we could activate the old web guiding system again at any time,” says Peter Schubert, technical director at Heukäufer Folien. “To be on the safe side, we initially left the old technology in the mono-extruder. At the turn of the year, the company began using the US 2010-type sensor positioner, equipped with two ultrasonic sensors, and the innovative controller. “The web guiding system on our mono-extruder had seen better days, so the inquiry came at just the right time,” says Managing Director of Heukäufer Folien, Kurt Barth. At that time, the company Heukäufer Folien was asked to conduct a beta test of the brand new technology. “Thanks to their high quality requirements, Heukäufer Folien, provider of flexible packaging solutions, was the ideal partner to test our FVG POS 100 sensor positioner and ekr 500 digital Unit Touch controller in practical use,” says Kai Prahl, Area Sales Manager at BST eltromat, looking back on autumn 2017. The web center-line guidings, with two ultrasonic sensors each, guide the webs accurately through the machines for the manufacturer of sophisticated foil bags and carrier bags. From extrusion and flexo printing, all the way through to assembly – at Heukäufer Folien GmbH, based in Herten, Germany, web guiding systems from BST eltromat International play a key role in quality assurance. ![]()
