摘要

Apparatus for fabricating a cellular laminated material from two plastic sheets includes a molding rotatable cylinder in contact with a pressure rotatable cylinder. Cooling water injection and air removal are accomplished within the interior of the molding cylinder. The contact portion of the two cylinders receives one of the plastic sheets. The other plastic sheet is cooled, heated and stretched prior to its being fed for embossing and laminating with the other plastic sheet on the molding cylinder. One embodiment has ends on the molding cylinder to provide an air-tight enclosure and the other embodiment is open at the ends thereof.
