摘要

Process for the manufacture of reinforced plastic material in the form of post-moldless endless sheet and installation for its implementation, characterized in that, on a sheet of cellophane paper from a coil, deposited and dragged by a circulating support as a non-end band, a uniform layer of ready-made plastic material consisting of a mixture of polyester resin with its filler, catalyst, accelerators, colorants, etc. Is poured on which layer another layer of reinforcing material is applied, also coming from of another coil, whose circulating assembly is subjected to the action of a pair of grooved rollers that, by means of pressure on alternating zones that cover the entire width of the product in manufacture, achieve the extraction of the air destroying the bubbles that could produce defects by occlusion in the finished sheets.
