Abstract

PROCEDIMIENTO PARA LA APERTURA RETICULAR DE PELICULAS FIBRILADAS. LA PELICULA O CINTA COMPUESTA POR UNA PLURALIDAD DE PELICULAS POLIMERICAS SINTETICAS FIBRILADAS ES EMPUJADA A TRAVES DE RODILLOS ALIMENTADORES (2) HACIA UN HORNO DE PRECALENTAMIENTO (3) DE DONDE PASA A UN PAR DE ENGRANAJES QUE IMPRIMEN EN LA CINTA ONDULACIONES TRANSVERSALES. AQUI LOS BORDES DE LA CINTA SON ATRAPADOS POR ELEMENTOS DE TRACCION (6) DE QUE VAN PROVISTAS DOS CADENAS DIVERGENTES (5) QUE AL SEPARARSE HACE QUE SE ABRA EN ABANICO LA CINTA O PELICULA FORMANDO UNA RED QUE ES ESTABILIZADA EN UN HORNO (7). LA RED ES SEPARADA DE LOS RETENEDORES AL PASAR SOBRE UNA BARRA (8) Y ES ENROLLADA EN UN CARRETE (9).
