Abstract
A device for the distribution of weft yarns into weft ducts of a rotor of a series shed loom has a first part (7) rotating with the rotor (2) with transfer ducts (11) for the weft yarns and a second part (8) which is nonrotatable in relation to the rotor (2) and has connecting ducts (10) for the weft yarns. The parts (7, 8) are axially aligned and movable with respect to one another and energy storing devices (24) hold them in an operating position so that there is a gap between opposing faces of the first and second parts (7, 8). An adjustable support structure permits adjustment of the gap width and then keeps it constant. The second part is connected to an operating mechanism (3) which pulls the second part (8) into an open position to thereby provide access to the transfer and connecting ducts (10, 11) for the weft yarns.
