69727-17 A feed system for running threads, in particular for delivering them to thread-processing machines, for example for inserting the weft thread into a loom, feeds the thread tangentially to a drum that is connected to a rotary drive. The thread drawn off the drum by a draw-off force that acts on the other, far side of the drum, the thread only looping around part of the periphery, the drum rotating at a peripheral speed that is greater than the thread draw-off speed. The thread is movable by a draw-off force tangential to the drum by slippage pull. Two adjacent and parallel drums have parallel axes and are divided by fixed intermediate walls so that each drum forms a plurality of areas (that lie one behind the other in the axial direction) for the thread to loop around such that the thread moves from an area of one drum to an area of the other drum. In order to optimize the operation of a feed system of this kind, the present invention proposes that the outer surface of each drum incorporates annular collars oriented radially outwards and aligned with the planes of the intermediate walls.
