Abstract
A convergent end-effector which combines a liquid and dry flow external to a spray nozzle eliminates clogging problems common in the prior art spray coating systems. The end-effector utilizes a nozzle with an orifice and at least one atomizing hole, a conduit for directing a liquid resin through the nozzle and an outer housing disposed around said conduit to form a cavity. Reinforcing material enters the cavity on an gas stream supplied and controlled by an eductor located prior to the outer housing, in the direction of the nozzle, and at an angle of less than about 90.degree. with respect to the conduit. The end of the conduit near the nozzle is preferably angled toward the nozzle to further direct the reinforcing material into the liquid resin.
