Abstract
PURPOSE: To eliminate the relief pattern transferring work and the transfer device through transferring of the relief pattern on a panel surface material with the foaming by pressing the panel surface material in a relief shape with a foaming pressure while solftening by heat during the foaming of a foaming resin.
CONSTITUTION: An isocyanate and a polyether resin are mixed and stirred with an urethane foaming machine and a panel surface material 1 on a belt 6 is filled with a foaming resin 3 (urethane resin by a foaming resin injection machine 13). Then, the panel 1 is delivered between an upper mold conveyor 7 and a lower mold conveyor 5 to perform an urethane reaction. During the reaction, the reaction heat rises above the softening point of the material 1 while the foaming pressure goes up. Thus, the panel surface material 1 softened is pressed against the belt 6 so that a concave and convex pattern of the belt is transferred on the material 1. The panel discharged with a double conveyor 4 is cooled and hardened to finish.
