ABSTRACT OF THE DISCLOSURE A method and apparatus particularly adapted for use in the continuous production of a foam material or the like. The apparatus essentially embodies a first material delivery and mixing means for delivering an atomized spray of a first material in one direction of flow, and for delivering a second generally annular stream of a second material about the first material such that both the first and second materials flow in substantially parallel directions wherein the first stream mixes in the core of the layer of second material, and for enabling the intimate and homogeneous mixing of the first and second materials; and a second material delivery and mixing means operatively connected downstream to said first material delivery and mixing means for forming the homogeneous admixture of the first and second materials into a generally annular stream which flows in substantially the same parallel direction as the first and second materials, and for introducing an atomized third material into approximately the center of the annular layered admixed stream such that the third material flows in substantially parallel directions to the annular stream of admixed first and second materials, and for enabling the homogeneous admixture of the first, second and third materials, such that the resultant admixture is discharged from said second material delivery and mixing means in a direction which is substantially parallel to the direction or flow of the first, second and third materials.
