Abstract: A method of manufacturing a multi-hardness and multi-elasticity foam mattress in which a plurality of foam blocks are formed integrally with each other by use of a continuous foaming process the method comprising the steps of: arranging a plurality of nozzles above one end of a molding plate; installing a separation wall between two adjacent ones of the respective nozzles arranged at the molding plate; laminating a release paper on the top of the molding plate; spraying foaming solutions from the nozzles, respectively, wherein the release paper moves in a direction toward the other end of the molding plate corresponding to a moving speed of the foaming solution; and molding a foam body having a plurality of zones where a plurality of unit foam blocks have multi-hardnesses and multi-elasticities.

Abstract: The present invention relates to a double-conveyor type apparatus for manufacturing a floor mat adapted to be disposed on a floor surface in an operating room in an industrial site, in various buildings or vehicles, or in an office room or house so as to reduce the impact or load transmitted to a human body and to prevent the sliding thereon, wherein the double-conveyor type apparatus includes a double-conveyor system having upper and lower conveyors formed of a plurality of unit upper and lower molds standardized to a given size and in series connected to each other is operated to allow a material of the floor mat to be passed thereon, thereby manufacturing the floor mat, such that the mass production of the floor mat can be simply and rapidly achieved to enhance the productivity.
