  • Yarn feeding device
    Patent number: 7261251
    Abstract: A yarn lifting element (28), which is provided on a positive thread regulating wheel, comprises straight yarn-bearing surfaces (34,35) whose position cannot be displaced by the yarn (2), enabling the yarn to slip in relation to the thread feeding wheel (17) when required. Said additional measure enables the positive thread regulating wheel to be used in areas which were previously excluded on account of the required synchronicity between the feeding of the thread and the consumption of the thread.
