Abstract
A method and apparatus is provided for compensating short duration thread tension fluctuations during feed of thread to a textile machine. The method includes blowing a jet of fluid medium along the thread in a direction opposite to the direction of travel of the thread from a delivery zone to a thread takeup zone. The blown jet of fluid medium produces a deflection of the thread from its straight path to form a storage or reserve of the thread from which thread may be taken during short-term fluctuations. The apparatus includes various forms of a blower mechanism and control means for providing the necessary storage or reserve of thread along its path of travel.
