Abstract

Process for filling molds suitable for the manufacture of shaped pieces of foam material, with particles of thermoplastic foam material, previously expanded, with simultaneous achievement of a previously determinable compression, characterized by the fact that, the space of the mold provided for the definitive molding, is first increased in a desired volume and after a total or partial filling of this volume increased with filling mass, it is reduced by exerting pressure once or several times on one or more mold limiting surfaces and filling compression to the desired volume or final, without this material filling material coming to the exterior or between the parts of the mold.
