  • Apparatus and process suitable for twisting a yarn
    Patent number: 4078371
    Abstract: A yarn is twisted by passing the yarn wound on a package to a tensioning zone and then passing the yarn to a 2-for-1 twist spindle and twisting the yarn. The tension applied to the yarn in the tensioning zone is the result of the sinusoidal path of the yarn through the tension zone and is a function of the amplitude of the yarn passing through the sinusoidal path.
