An apparatus for the selective feeding of one of a plurality of weft threads (1) to a gripper projectile, which moves along a projectile path (2), includes a plurality of displaceable feeders (3) each having a feeder clamp (7) for retaining a respective weft thread (1) in position for pick up, a knife (4) for cutting off the weft thread (1) after it has been drawn into the weaving shed by the gripper projectile, and a clamp for picking up the weft thread (1) from a feeder and drawing the weft thread (1) transversely across the projectile path (2) for engagement by the gripper projectile. The clamp is mounted on a rotatable ring (6) which is disposed perpendicular to the projectile path (2) which extends through the ring.
