Abstract

LA INVENCION SE REFIERE A UN METODO Y A UN APARATO PARA PRODUCIR UNA HOJA DE PLASTICO EN FORMA DE BANDA CONTINUA (19). POR MEDIO DEL APARATO DE ACUERDO CON LA INVENCION, SE ENTREMEZCLAN UN POLIMERO EN FORMA DE GRANULADO O DE POLVO Y UN RELLENO DE PARTICULAS, DESPUES DE LO CUAL LA MEZCLA ES EXTRUIDA A TRAVES DE LA ABERTURA DE UN TROQUEL (18) PARA FORMAR LA HOJA DE PLASTICO FINALIZADA. PARA FACILITAR EL ENTREMEZCLADO DE LOS MATERIALES INICIADORES ANTES PRESENTADOS, EL POLIMERO EN FORMA DE GRANULOS O DE POLVO SE PLASTIFICA Y SE DESAIREA ANTES DE SU MEZCLA CON EL RELLENO EN PARTICULAS.
