For six years, the KDF 6LEAD filter maker has stood for precision and maximum flexibility in the high-speed range of 600 m/min. “In combination with the FLEXPORT product range, customers can use it to produce filters with capsules, granules, threads, flavors and channel ventilation,” explains Enno Köster, Product Consultant. “The missing link, until now, was the ability to produce NWA filters using the flexible filter maker. These are increasingly in demand for cigarettes and THP. We have now solved that problem.”
Combination of proven solutions
To allow NWA filters to be manufactured on the KDF 6LEAD, Hauni began work on connecting its filter maker to the NWT module in early 2020. “The development work was completed very quickly. The two systems were ‘married’ in July and we immediately put the new version of the machine into operation,” reports Joannis Geroliolios, Project Manager. “As well as performing the mechanical and electrical integration of the NWT module, we created the necessary software interfaces and developed a new transport module for transferring the tow from the AF via the NWT module to the FLEXPORT.” Hauni has also integrated a camera-based ICPS sensor into the new machine design for enhanced quality assurance. This reliably checks each individual filter rod to ensure that the front surface meets the quality criteria.
