发明名称 PROCEDE ET APPAREIL POUR LE TRAITEMENT DE FEUILLES DE RESINES THERMOPLASTIQUES
摘要 Method for treatment of a solid material submerged in a body of liquid wherein the material is sticky and/or has relatively low tensile strength. The material being treated is supported, while so submerged, by a dynamic boundary layer of a liquid material between the treated material and a stationary porous restraining surface, the layer being created by the forced diffusion of said liquid through the pores of said stationary surface. The method is illustrated by heating and thereby foaming a strip of heat foamable thermoplastic resin while it is held submerged in a denser heat transfer liquid by a dynamic layer of said heat transfer liquid, said layer of heat transfer liquid being created by the forced diffusion thereof through a porous plate in operative communication with a pressurized chamber containing a supply of said liquid.
