ABSTRACT:
A friction thread feed device having at least two drums (5, 6) which are arranged spaced apart from each other and are partially wrapped by the thread (F), the drums being driven in the direction of travel of the thread (F) with a circumferential speed which is considerably greater than the thread removal speed. In order to avoid the layers of thread passing onto each other upon multiple wrappings on the drums and also in the case of threads of difficult shape, partitions (17, 18) which divide the drum outer surfaces into individual adjacent regions which are axially offset from each other are fastened in the region of the space between the drums (5, 6 ).
