Zusammenfassung:The invention provides an apparatus for compressively molding cushioning material using a quadrangular cylindrical molding box (12) having an end side closed by a receiver mold (13), whereas the other end of said molding box receives supply of dry raw material (M) consisting of fiberized paper or pulp by a volume corresponding to several times the actual volume of a molded body. A compressive mold (41) inserted from the other end of the molding box is shifted to one-end side of the molding box to compress supplied raw material (M) between a receiver mold. Simultaneously, a core member (14) is retreated to a predetermined position of said one-end side in association with the shifting movement of the compressive mold. As a result, the core portion having thin thickness and the interior of the core member can securely be compressed and molded with even density.
