Abstract

Device for continuous production of molded, thin-walled pieces of thermoplastic material, containing: at least one extruder capable of receiving a granulated, compressed thermoplastic material and continuously reheating it until it passes to the fluid state; a row of extrusion press that follows the extruder or the extruders, arranged in a flat row and equipped with temperature regulation devices; a thermoforming device for forming in the material belt shaped parts by embossing or stamping, and apparatus for cutting the molded parts in the belt, the said device being characterized by: a) a stabilization and cooling apparatus, which directly receives the belt of material from the flat row, and provided with cooling elements, which attack the two surfaces of the strip of material in heat conducting contact, the said apparatus being attached to organs for regulating the temperature of the cooling elements in a determined value ; b) an apparatus that guides vertically, in the direction of its length, the strip of material that must be deformed through the thermoforming device; c) a system of forming tools, with their auxiliary organs, which is installed in the thermoforming device, and in which the part of the forming tool that the material tape must receive is located horizontally opposite the tape; d) an apparatus installed on the thermoforming device, to separate the molded parts from the material strip, a part of the separation apparatus being associated to the forming tool, but separated from it, at least thermally, while the second complementary part of the separation apparatus, is disposed horizontally in front of the rear face of the tape guide.
