The Karl Mayer Group, Obertshausen/Germany, will take over the complete range of YTC products (YTC-2000 AND YTC-2000 MAX) and the complete technology of yarn tensioners for weaving and warp knitting preparation from Appalachian Electronic Instruments Inc. (AEI), Lewisburg, VA/USA. The after sales service for the installed base machines will be taken over by Karl Mayer effective September 1,2022. AEI will continue to provide support to Karl Mayer and the customers during the transition. As market leader and full range supplier in indigo dyeing, Karl Mayer Group will complete their yarn tensioner product range with this integration of the YTC technology.
Since patenting the first electronic disk tensioner in 1979 AEI is one of the leading suppliers of yarn tensioners for denim and warp knitting applications. After 43 years, AEI has made the decision to exit the tension control market and focus on its patented broken and tight yarn monitoring technology.
