Abstract

SE DESCRIBE UN METODO PARA AISLAR UN TUBO ESPIRALMENTE BOBINADO DE UN PERFIL HUECO TERMOPLASTICO. LA INVENCION SE CARACTERIZA PORQUE A TRAVES DE CADA UNA DE LAS PAREDES LATERALES RADIALMENTE DIRIGIDAS (2) DE UN PERFIL AGUJERO (1) EN EL TUBO, SE REALIZA AL MENOS UN AGUJERO AXIALMENTE DIRIGIDO (3,3A) DE FORMA QUE UNA FILA DE AGUJEROS (3,3A) LOCALIZADOS EN LINEA UNOS CON OTROS SE FORMA A TRAVES DE TODO EL TUBO, MIENTRAS ESTE ESTA EN POSICION HORIZONTAL Y UNA FILA DE AGUJEROS (3A) SE LOCALIZA EN EL TUBO MAS SUPERIOR, UNA LANCETA DE ESPUMA (4) SE INTRODUCE DENTRO DE LA FILA DE AGUJEROS (3,3A) A TRAVES DEL TUBO, UNA MASA DE AISLANTE DE ESPUMA (5) SE DOSIFICA POR TURNOS DENTRO DE CADA SEGMENTO DEL TUBO ESPIRALMENTE BOBINADO DESPUES DE QUE LA LANCETA SE EXTRAE FUERA DE LOS AGUJEROS, CUANDO TODOS LOS AGUJEROS TALADRO (3) SOBRE LA SUPERFICIE EXTREMA DEL TUBO SE OBTURAN, CUANDO SE COMPLETA LA ESPUMACION.
