APPALACHIAN ELECTRONIC INSTRUMENTS INC. (AEI) and KARL MAYER GROUP agreed on August 2nd, 2022 that AEI will transfer their YTC yarn tensioner technology to KARL MAYER.


Since patenting the first electronic disk tensioner in 1979 AEI has been a pioneer and leading supplier 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.
