Aparato y procedimiento para fabricar paneles realizados en material plástico expandido

MATERIAL QUE COMPRENDE POR LO MENOS UN MARCO DE CONFINAMIENTO PERIMETRICO QUE DESTINADO A SER SUJETADO ENTRE UN PAR DE SUPERFICIES DE PRENSADO DE UNA PRENSA PARA DELIMITAR LATERALMENTE POR LO MENOS UNA CAVIDAD DE EXPANSION PARA UNA MEZCLA DE EXPANSION, POR LO MENOS UNA PARTE DEL MARCO PERIMETRICO DEFINE INTERIORMENTE A LO LARGO DE SU EXTENSION POR LO MENOS UN CANAL DE PASO DE AIRE QUE ESTA CONECTADO CON POR LO MENOS UN ORIFICIO DE ADMISION DE AIRE QUE ESTA DEFINIDO EN LA SUPERFICIE DEL MARCO PERIMETRICO QUE ESTA DIRIGIDA HACIA EL INTERIOR DE LA CAVIDAD DE EXPANSION Y CON POR LO MENOS UN ORIFICIO DE CONEXION. An apparatus for manufacturing panels made of expanded plastic material comprising at least one perimetric confinement frame clamped between a pair of pressing surfaces of a press in order to delimit laterally at least one expansion cavity for an expanding mixture. At least one portion of the perimetric frame defines internally, along its extension, at least one air passage channel that is connected to at least one air intake port, which is defined in the surface of the perimetric frame that is directed toward the inside of the expansion cavity, and to at least one connection port, which is defined in the surface of the perimetric frame that is directed toward the outside of the expansion cavity and adapted to be connected to at least one air suction device.
