Abstract
A method and apparatus for feeding a thread to a textile machine in a twist-free manner, which thread has a band-like character. The thread is taken twist-free from a stock and is stored on a stationary storage drum in a thread feeding apparatus. The thread feeding apparatus has a rotatable central shaft and a winding element which protrudes therefrom. During operation of the thread feeding apparatus, functional twists are produced in the thread only during the transition from the central shaft into the winding element. The twists are inhibited from being transported oppositely to the thread path direction and are regularly conveyed to the storage drum in almost perfect match with the rotations of the central shaft. At least one guide gap that is stationary in relation to the central shaft is provided along the thread path in the area of transition of the central shaft into the winding element.
