Thread supplying device for intermittent thread consumption

摘要

A thread supplying device with intermittent thread consumption has at least one thread supplying unit including a rotatable thread supplying drum and a thread supplying device. The thread supplying drum has a first and a second peripheral portion forming corresponding friction surfaces for a thread to be supplied. The thread supplying device has an inlet element associated with the first peripheral portion and an outlet element associated with the second peripheral portion, and also has two movable guiding elements for the thread and associated with the peripheral portions. The thread is guided by the guiding elements between the inlet and the outlet element and cooperates successively with the first and the second peripheral portion and placed on an associated one of the peripheral portions in a supplying position of the guiding elements along a greater peripheral angle than in a non supplying position of the guiding elements.
