Abstract

The present invention relates to a method and apparatus for molding continuously a foamed plastic board (100). For molding continuously a foamed plastic board (100) using preliminary granular foam, the present invention provides an apparatus for molding continuously foamed plastic board (100) comprising: a filling and transferring means (10) for filling continuously preliminary granular foam in the form of sheet to mold a foamed plastic board (100) while the preliminary granular foam is foamed by dry vapor, and transferring the foamed plastic board (100); a maturing means (20) for maturing the foamed plastic board (100) molded by the filling and transferring means (10); and a cutting means (30), such as a cutter, for cutting the foamed plastic board (100) matured by the maturing means (20) by the fixed size.
