ABSTRACT:
A nozzle suitable for mixing atomized first and second components of a resin exterior to the nozzle and combining the atomized and combined resinous components with a base material such as a fibrous or granular insulation material. The nozzle comprises a front plate and a back plate, the back plate individually receiving under pressure the first component and second component of the resin, a base material and an air supply. The front and back plates are secured in registry to each other so that central passageways in the front and back plates communicate the base material through the nozzle to be exhausted onto a surface. The air supply is communicated through the back plate to a continuous channel on the surface of the back plate in registry with the front plate and the first and second components of the resin are transmitted through the back plate by means of single passageways on either side of the continuous air channel. A pair of continuous channels on the surface of the front plate individually communicate with the passageways for the first and second resinous components. A plurality of air holes on the surface of the front plate in registry with the back plate communicates with the continuous air channel on the back plate. Each of the continuous channels on the front plate contain a plurality of apertures, one plurality leading to a corresponding plurality of atomizer jets on the outside surface of the front plate and the other plurality leading to a second corresponding plurality of jets on the outside surface of the front plate. The air holes in the front plate are drilled at angles such that the air supply communicates with both pluralities of atomizer jets. The first and second components of the resin are therefore individually atomized and combined with a base material exterior to the nozzle.
