1. 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; anda 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 andwherein 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. 2. The system of claim 1, wherein the retractable piston assembly comprises: a bearing adapted to rotatably receive a shaft in a first direction, the bearing being movable in a second direction substantially perpendicular to the first direction;a fluid cylinder in operative association with a movable piston, said piston being interconnected with said bearing, said fluid cylinder including a fluid inlet for receiving a pressurized fluid, wherein, when a pressurized fluid is introduced into said cylinder, said piston applies a force to said bearing in said second direction; anda fluid regulator in communication with said fluid inlet for controlling and regulating the pressure of a fluid within said cylinder, said fluid regulator controlling the amount of fluid entering and exiting said fluid cylinder from a pressurized fluid source, wherein said fluid regulator is configured to adjust the fluid pressure within the cylinder to either retract or extend the piston. 3. The system of claim 2, wherein the fluid cylinder is a pneumatic cylinder. 4. The system of claim 1, wherein the retractable piston assembly comprises: a block having a bearing adapted to rotatably receive a shaft in a first direction, the bearing being movable in a second direction substantially perpendicular to the first direction;a motion transmission screw connected to the block at one end and extending therefrom through and in threaded engagement with a nut. 5. The system of claim 1, wherein the carrier sheet comprises at least one of fluorine resins, silicone resins, polyimides, polyphenylene sulfides, polysulfones, polyether sulfones, polyether imides, polyether ether ketones, para type aramid resins; thermoplastic polyester resins, or thermoplastic polyester type elastomer resins. 6. The system of claim 5, wherein the endless belt comprises at least one of polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkylvinyl ether copolymers, tetrafluoroethylene-hexafluoropropylene copolymers, tetrafluoroethylene-ethylene copolymers, dimethyl polysiloxanes, dimethylsiloxane-diphenyl siloxane copolymers, polyethylene terephthalates, polybutylene terephthalates, polyethylene naphthalates, polybutylene naphthalates, polycyclohexane terephthalates, polyether block copolymers, or polyester block copolymers. 7. The system of claim 1, wherein the belt is an endless belt. 8. The system of claim 7, wherein the endless belt comprises at least one of films, non-woven materials, or woven materials. 9. The system of claim 1, wherein the High Internal Phase Emulsion extruder is at least one of a die, sprayer, or caster. 10. A High Internal Phase Emulsion foam producing system comprising: an 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; anda rotatable shaft adapted to support and rotate with the carrier sheet, the rotatable shaft having a first end and a second end;a retractable piston assembly, mounted to the first end and second end of the rotatable shaft; 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 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. 11. The system of claim 10, wherein the retractable piston assembly comprises: a bearing adapted to rotatably receive the shaft in a first direction, the bearing being movable in a second direction substantially perpendicular to the first direction;a fluid cylinder in operative association with a movable piston, said piston being interconnected with said bearing, said fluid cylinder including a fluid inlet for receiving a pressurized fluid, wherein, when a pressurized fluid is introduced into said cylinder, said piston applies a force to said bearing in said second direction; anda fluid regulator in communication with said fluid inlet for controlling and regulating the pressure of a fluid within said cylinder, said fluid regulator controlling the amount of fluid entering and exiting said fluid cylinder from a pressurized fluid source, wherein said fluid regulator is configured to adjust the fluid pressure within the cylinder to either retract or extend the piston. 12. The system of claim 11, wherein the fluid cylinder is a pneumatic cylinder. 13. The system of claim 10, wherein the retractable piston assembly comprises: a block having a bearing adapted to rotatably receive the shaft in a first direction, the bearing being movable in a second direction substantially perpendicular to the first direction;a motion transmission screw connected to the block at one end and extending therefrom through and in threaded engagement with a nut. 14. The system of claim 10, wherein the carrier sheet comprises at least one of fluorine resins, silicone resins, polyimides, polyphenylene sulfides, polysulfones, polyether sulfones, polyether imides, polyether ether ketones, para type aramid resins; thermoplastic polyester resins, or thermoplastic polyester type elastomer resins. 15. The system of claim 14, wherein the endless belt comprises at least one of polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkylvinyl ether copolymers, tetrafluoroethylene-hexafluoropropylene copolymers, tetrafluoroethylene-ethylene copolymers, dimethyl polysiloxanes, dimethylsiloxane-diphenyl siloxane copolymers, polyethylene terephthalates, polybutylene terephthalates, polyethylene naphthalates, polybutylene naphthalates, polycyclohexane terephthalates, polyether block copolymers, or polyester block copolymers. 16.
