A machine with wide appeal - KARL MAYER Textilmaschinenfabrik GmbH

KARL MAYER Malimo’s development work is continuing to focus on weft-insertion warp knitting machines. Following the improvements made to the HKS MSU S high-speed tricot machines with parallel weft insertion at the end of last year, a completely revamped machine platform was unveiled to coincide with the ITMA exhibition. This totally new basic concept bears the tradename, Weftronic*, and is being implemented systematically on every weft-insertion warp knitting machine. An RS MSU S warp knitting machine with parallel weft insertion set things in motion, and was being shown at KARL MAYER (China) Ltd. in Wujin to coincide with the ITMA ASIA+CITME exhibition. This high-tech production machine was demonstrating its capabilities to an audience of mainly Chinese visitors during the machine presentation in Wujin, and impressed them with a level of efficiency that is unparalleled anywhere in the world. The working width of the new Weftronic* is 600 mm larger than its predecessor, although the speed is the same. Increasing the width to 268" means that fabrics having widths of up to 6,800 mm can now be produced but, above all, the square metre production rate is considerably higher. The technical principles behind this considerable increase in performance are a number of innovations that are all harmonised with each other, one of which is the all-important weft insertion system, which has been fundamentally re-engineered. A much-improved weft chain has been fitted on both sides of the unit that forms the heart of the machine, which comprises the transfer station, the yarn-laying carriage and the yarn take-off device from the creel, and its mode of operation has also been improved using sophisticated technology. In addition to improving the machine’s efficiency, the user friendliness was also at the centre of the further development work. The design of the new Weftronic* allows easy access to all the main components, and assembly is simplified by dividing up the entire machine into component groups that are all harmonised with each other. Rapid integration into the manufacturing process saves assembly costs and reduces the amortisation period. The Weftronic*, with all its new technical features, will be available as of the ITMA ASIA+CITME 2010 fair. Another model with a working width of 138" will be available by the end of this year on the same machine platform. This new machine, with even more improved features, will be available to view for the first time at the ITMA 2011 fair in Barcelona.
