Abstract

Process for making thermoformed objects, starting from a thermoplastic laminate comprising at least one sheet of cellular structure and one sheet of non-cellular structure, characterized in that the reheating of the sheets that must be associated with their optimum temperature, the association of these sheets heated by pressing, and the subsequent thermoforming of the laminate thus formed, are carried out continuously in a closed and heated enclosure.
