Abstract

PURPOSE: To reduce an amount of urethane to be used and improve the stiffness of a product by a method wherein styrene balls, made by applying steam to styrene raw beads more than one time, are dropped and put on a surface member coated with urethane resin uniformly, thereafter, are foamed.
CONSTITUTION: Steam is applied to the styrene raw beads in a steam chamber 1 more than once to make the styrene balls, then, the styrene balls are received into a styrene ball hopper 2. On the other hand, urethane liquid resin in a urethane liquid resin tank 3 is coated uniformly to a formed steel sheet 5 obtained by extrusion molding or press molding with a spray nozzle 4 to form the urethane resin layer 6. Subsequently, the styrene balls 7 are dropped from the hopper 2 onto the urethane layer 6 uniformly, thereafter, they are foamed by heating them at a temperature of 40W50°C from above and below with hot press boards 8, 8 thereby obtaining the product 9 formed to one body by compression.
