Abstract
A multiple needle tufting machine having a multiplicity of yarns and a high tension detector for detecting when the tension of any yarn between the tufting machine and a yarn supply deviates from a predetermined normal and for identifying the particular yarn that so deviates. The detector includes a yarn contacting member for each yarn urged into engagement with the yarn for reacting to tension variation and to close a switch when the tension is excessive. Two electrical circuits for identifying the particular switch, and therefore yarn, are disclosed.
