Abstract
An apparatus suitable for the continuous preparation of a polymer-based cellular foam sheet of a predetermined thickness wherein the foam is produced from a reaction product capable of curing at ambient temperature formed by the reaction of a reactant composition including a prepolymer and water, the apparatus including: a means for reacting the reactant composition, a continuously moving substrate for receiving a quantity of the reaction product; a means for depositing the quantity of reaction product onto the substrate to form a rising foam sheet; a means for compressing the rising foam sheet to a predetermined degree, the compressing means being spaced from the depositing means; and a curing means spaced from the compressing means and providing for a rising of the foam sheet exiting from the compressing means to provide a porous foam sheet having the predetermined thickness.
