Abstract

PURPOSE:To obtain efficiently the captioned form covered with another material integrally by a method wherein the other material is retained temporarily at the part of the necessary forming surface of split molds and an adjesive is applied, thereafter, thermoexpandable resin baeds are filled into the cavity of the molds to expand by heating. CONSTITUTION:In case the resin beads expanded form covered with the other material 3 integrally at the required part of the form is manufactured, the objective other material 3 is retained temporarily at the part of the requested forming surface of the split molds 4, 5 through temporary retaining material 7 and the adhesive 8 is applied to the surface connecting the material 3 to the resin beads expanded form. Subsequently, both of the molds 4, 5 are clamped and the thermoexpandable resin beads are poured and filled into the cavity 6 to be formed through a pipe 57 to fill up it, thereafter, steam or hot air is blown into the cavity through the injection ports 46, 56 to expand the filled beads thereby obtaining the captioned form.
