ABSTRACT:
The gripper projectile has a yarn clamp with clamping jaws which, when opened to receive a weft yarn, bound a flow duct. The duct is disposed in communication with air exit orifices in the casing of the projectile so that air which is injected by a yarn supplying device and entraining the weft yarn end flows through the duct without turbulance. The clamping jaws may be provided with recesses for ducts to further center the delivered weft yarn. In other embodiments, inserts may be provided within the projectile casing to form nozzles for the flow of air to the exit orifices.
