ABSTRACT:
The invention relates to a process for the production of a very thick, self-supporting, Z-shaped plastic laminate, starting from a plurality of Kraft papers imbued with phenolic resin, possibly with a superposed sheet of decorative paper imbued with melaminic resin, said papers being pressed in two successive processing phases; in the first phase the pressure is kept at a minimum level, while the temperature of the papers rises up to the temperature of polymerization of the resins, and in the second phase the temperature keeps at a substantially constant level while the pressure rapidly increases, at least initially.
