The yarn clamp 13, 14 includes a carrier which can move to swing in time with the reed 2 and has two oscillating levers 7, 10 which carry at their ends the jaws 13, 14 which grip the weft yarn. The one oscillating lever 7 is connected rigidly to the carrier, while the other lever 10 is stressed elastically via a rubber sleeve 12 into the gripping position with the one oscillating lever 7. The jaw 14 is held back by cooperation with a stop 15, while the jaw 13 moves on. The yarn clamp 13, 14 hereby automatically gets spread for the release of the end of the weft yarn or respectively for accepting the next weft yarn end.
