Endless-chain systems for feeding weft threads to weft inserters

For use in a travelling-wave loom, a system for individually feeding a plurality of weft threads from a plurality of bobbins to weft inserters disposed in spaced relation along a first endless chain, the system comprising, in combination, a plurality of winding units individually associated with the bobbins and adapted to present the weft threads to the respective weft inserters, a second endless chain guided along an oval track, means for associating the winding units with spaced portions of the second chain, common drive means, and means associated with the first and second chains and adapted to cooperate with the common drive means for ideally effecting synchronous movement of the first and second chains, the improvement wherein the second chain comprises a plurality of rigid carrier members disposed in spaced relation, the movement effecting means comprises a contact surface disposed on each carrier member, and the associating means comprises means for individually and removably connecting the winding units to the respective carrier members.
