Abstract

PELICULA EMBUTIDA ORIENTADA O DE RESISTENCIA AUMENTADA QUE ES PRODUCIDA INTRODUCIENDO UNA PELICULA TERMOPLASTICA, CUYA SUPERFICIE ESTA CUBIERTA POR UN LUBRICANTE LIQUIDO INTERTE, DENTRO DEL PUNTO DE CONTACTO ENTRE AL MENOS UN PAR DE RODILLOS DE COMPRESION GIRATORIOS QUE ACTUAN A PRESION SUFICIENTE PARA REDUCIR EL ESPESOR DE LA PELICULA Y, SIMULTANEAMENTE, EMBUTIENDO AL MENOS UNA DE LAS SUPERFICIES DE LA PELICULA QUE SE HALLA DENTRO DEL PUNTO DE CONTACTO. AUNQUE SE PUEDEN UTILIZAR VARIOS LIQUIDOS INERTES COMO LUBRICANTE, PREFERENTEMENTE SE UTILIZARA PARA ESTE FIN. EL LUBRICANTE PROPORCIONA UNA CUÑA HIDRODINAMICA EN LAS SUPERFICIES DE CONTACTO DEL RODILLO QUE COMPRIMEN LA PELICULA, Y PARA OBTENER MEJORES RESULTADOS ES PREFERIBLE PULVERIZAR EL LUBRICANTE (MEJOR, AGUA) DENTRO DE AMBOS LADOS ENTRANTES DEL PUNTO DE CONTACTO DE LOS RODILLOS DE COMPRESION.
