ABSTRACT:
The present invention is directed to an apparatus for the distribution of a foamble reaction mixture upon a moving base. The present invention is directed to the discovery that by injecting small amounts of air into both ends of a conventional pipe-type dispenser, the operation time without any plugging can be substantially increased. The air flow prevents build-up of reaction mixture around the dispensing holes.
