Abstract
A system for continuous High Internal Phase Emulsion (HIPE) foam production. A (HIPE) is produced then extruded onto a carrier sheet positioned on a belt surface.
Claims20
A High Internal Phase Emulsion foam producing system comprising:
- a High Internal Phase Emulsion extruding device that extrudes a High Internal Phase Emulsion;
- a belt;
- a carrier sheet, wherein at least a portion of the carrier sheet is in contact with the belt and is configured to provide a releasable surface for the produced High Internal Phase Emulsion foam to be substantially free from surface irregularities and to reduce formation of defects in the produced High Internal Phase Emulsion foam;
- and
- a retractable piston assembly, wherein the retractable piston assembly is in operable association with the carrier sheet;
- wherein the retractable piston assembly is capable of positioning the carrier sheet directly under the extrusion device or away from and not under the extrusion device;
- wherein the extruding device is configured to extrude the High Internal Phase Emulsion onto the carrier sheet and
- wherein the carrier sheet is configured to rest upon the belt and to move in a horizontal direction along with the belt to transport the High Internal Phase Emulsion from the extruding device to a following stage of High Internal Phase Emulsion foam production.
