Abstract

PURPOSE: To make a filler distribution uniform by supplying a foaming synthetic resin and a flame retarding filler between opposite positioned surfacial materials, forming protrusions on the internal surface of the surfacial material at a fixed pitch and feeding a filler from a specified spot at time of foaming.
CONSTITUTION: A surfacial material 1 of solid basic material such as gypsum board, etc. and a flexible surfacial material 2 laminated with a craft paper formed with protrusions provided at a fixed pitch on one side, are fed in such manner that the both surfacial material are opposed to each other, the protrusions on the surfacial material being positioned inwardly. Then a liquid synthetic resin of foaming type 3 such as urethane, etc. is sprayed onto the surfacial material 1 through the medium of a nozzle 4 and at the same time, a gap ΔG between the both surfacial material 1, 2 is controlled by means of a roll on an elongation device 7. At this spot where the both surfacial materials 1, 2 are opposed to each other, the flame retarding filler 5 such as rockwool, etc. is added by means of a feeder 6, so that it is caused to foam for molding between an upper and a lower molding material 10, 11 through a conveyer 8.
