Abstract

Método para la producción de cintar de soporte de cierre de cremallera de cursor, caracterizado porque comprende las etapas de: proporcionar un par de cadenas sin fin superior e inferior de bloques de molde que tienen cada uno una cara de molde correspondiente, dotada de una serie de cavidades de medio molde espaciadas uniformemente y un medio canal; transferir un par de dichos bloques superior e inferior de molde a una posición en la que dichos bloques de molde se corresponden para proporcionar un molde que tiene una serie de cavidades de molde espaciadas uniformemente y un canal, y en la que dichas cavidades de molde comunican con una pluralidad de canales de colada secundarios en un colector caliente de canales de colada que recibe un suministro de material fundido bajo presión; introducir una cinta de soporte en dicho canal con su borde acordonado dispuesto en dichas cavidades de molde; alimentar el material fundido bajo presión a través de dichos canales de colada secundarios en dichoscavidades de molde; mover dicho molde lleno de material fundido a otra posición en la que el material fundido se solidifica; y separar dicho molde en un par de dichos bloques superior e inferior de molde a fin de formar de esta manera una serie de elementos de acoplamiento individuales en dicho borde acordonado de cinta al mismo tiempo y en un tramo correspondiente a la longitud de dicho molde.
