Abstract
The present invention is directed to an improved method for preparing a product by introducing a rigid polyurethane foam formulation into a cavity defined by two spaced apart formed sheets and allowing the formulation to foam. In one embodiment, the improvement resides in providing at least one of the sheets with a portion having the shape of a gate of the type used in polyurethane reaction injection molding and introducing the formulation through that gate so that the formulation enters the cavity as a laminar stream.
