ABSTRACT:
Foam forming liquid components and inert gas are directed by a gun in separate and discrete streams toward a common focal point just forward of the gun nozzle to effect mixing of the liquid components as the foaming plastic mass is directed into a container provided to receive and contain the foam product. Mixing of the liquid components within the gun which controls the flow is entirely avoided whereby the difficult problem of cleaning out reacted plastic material is entirely avoided even after long periods of non-use. In one technique, air is continuously mixed with each liquid component stream within the gun to provide frothy mixtures of liquid and air at the point of mixing of the reacting streams. A flexible extension of the nozzle may be used, if desired, to conduct the component liquids and air to a location some distance forwardly of the gun. Provision is made for air-purging the liquid component channels within the gun nozzle.
