Patent ID: 8257787

Claim:
A method for producing a High Internal Phase Emulsion foam comprising the steps of: forming a High Internal Phase Emulsion from an oil phase comprising monomer, cross-linking agent, emulsifier, and an aqueous phase; providing an extrusion device, providing a belt; providing a carrier sheet, wherein at least a portion of the carrier sheet is contact with the belt; providing a retractable piston assembly that is in operable association with the carrier sheet wherein the retractable piston assembly is capable of positioning the carrier sheet under the extrusion device or away from the extrusion device; extruding the High Internal Phase Emulsion on the carrier sheet; activating the retractable piston assembly in a manner that the carrier sheet is positioned under the extrusion device, such that the High Internal Phase Emulsion is extruded on the carrier sheet; polymerizing the monomer component in the oil phase of the High Internal Phase Emulsion.
