  • Patent number: 5072760
    Abstract: In a device for drawing a weft yarn (2) into a weft accumulator of a loom, weft yarn is wound during weaving by a winding tube (41') on to a stationary accumulator drum (400) and drawn off the same. To draw in the web yarn (2) the tube (41') is so rotated as to register with the inlet of a slotted tube (51). The same extends externally around the drum (400) as far as an eye (60) disposed on the draw-off side of the drum (400). An injector nozzle (43) on the entry side of the accumulator draws the weft yarn automatically through the winding tube (41') and the slotted tube (51) as far as the yarn eye (60).
