Abstract
EL INVENTO SE REFIERE A UN PROCEDIMIENTO DE TRATAMIENTO ANTIADHERENTE EN CONTINUO DE UN CORDON DE MATERIAL ADHESIVO PERMANENTE, MAS PARTICULARMENTE DE UN ADHESIVO TERMOFUNDIBLE QUE SALE DE UN MEZCLADOR EXTRUSOR O DE UNA TERRAJA A UNA TEMPERATURA SUPERIOR A SU TEMPERATURA DE ABLANDAMIENTO. PROCEDIMIENTO CARACTERIZADO PORQUE SE APLICA ALMENOS UNA PARTE DE LA SUPERFICIE DEL CORDON CON UN REVESTIMIETO DE UN AGENTE ANTI-ADHERENTE COMPATIBLE CON EL MATERIAL CONSTITUTIVO DE ESTE Y QUE NO ARRASTRA MODIFICACION FISICO-QUIMICA ALGUNA DE DICHO MATERIAL, SE ENFRIA EL CORDON ASI REVESTIDO, DESPUES SE CORTE EN LA LONGITUD DESEADA Y SE ACONDICIONAN DIRECTAMENTE LOS FRAGMENTOS ASI OBTENIDOS SIN PRECAUCION SUPLEMENTARIA. EL INVENTO SE REFIERE IGUALMENTE A UNA INSTALACION PARA LA APLICACION DEL PROCEDIMIENTO.
