All components under control ▲ ▲ New cable coating system from Extrudex s

The trial run of the new cable coating line ran just like clockwork. It was quite an achievement to jacket a variety of cables in a variety of polymers (PVC, PUR, TPE and HFFR) during the entire acceptance phase. The more than pin-point accurate laser measurement system integrated into the line – to an accuracy of 10,000 th of a millimetre – monitors even higher accuracy than the permitted tolerance for the cable. This is entirely due to highly precise Lenze servo control. The system is extremely accurate with regard to wall thickness control, performance enhancing and economic when it comes to materials as well as energy. The system is easily and quickly changed over, for example

from a yellow-coated single-core 7mm earth cable with two green stripes to multi-core and thicker or thinner cables. Extrudex can manufacture power lines with a maximum thickness of 55mm. Those, however, will be run straight, ie without dancer or cable accumulator and without diverters. Cables up to 30mm diameter are run with dancer and cable accumulator control. The entire line has a length of 43 metres, with a process length more than three times that. As a space-saving measure, storage lines are placed above the cooling line, running in the opposite direction. They are indispensable in allowing the change of the cable drum without stoppage.

High-end technology guarantees speed, accuracy and sustainability. This could be the headline for the order to develop and produce a new cable coating system. The line was ordered by the cable manufacturer Lapp GmbH, at the end of 2011, designed and built by Extrudex Kunststoff in Mühlacker, Germany, and accepted by the customer at the end of June 2012. The line went into production at Lapp GMBH Kabelwerke in Stuttgart, Germany, during the summer of 2012. Lapp designs and produces cables and conductors for different industries and markets, such as mechanical and systems engineering, the automotive industry, MSR technology, electrical and installations engineering, and EDC, among many others.
