Abstract
The gripper projectile has a spring-biased clamping member which is biased against a guide nozzle into which a weft yarn is blown in by a weft yarn supplying nozzle. The clamping member is provided with an aperture which enables a projectile opener to be introduced to retract the clamping member from the nozzle to permit the nozzle to directly communicate with discharge orifices in the side walls of the projectile. With the clamping member in the retracted position, a weft yarn end can be delivered while the yarn entraining air is immediately discharged along with any fluff that may be carried by the air stream.
