Abstract

Se describen estructuras de película de capas múltiples que tienen perfiles anulares, y métodos y aparatos para elaborar las estructuras descritas. Los artículos de capas múltiples anulares tienen un espesor uniforme, de por lo menos cuatro capas y comprenden áreas circunferenciales traslapadas y no traslapadas; en donde la estructura de la capa del área no traslapada es duplicada en la capa traslapada. Un método para la elaboración de la estructura incluye proporcionar una corriente de flujo de capas múltiples con por lo menos cuatro capas de materiales resinosos termoplásticos; alimentar la corriente de flujo de capas múltiples a un múltiple de distribución de un troquel anular para formar una corriente anular de flujo de capas múltiples; y remover la corriente anular de flujo de capas múltiples del troquel anular para formar la estructura anular de capas múltiples. También se describe un aparato, que comprende: un bloque de alimentación, con un multiplicador óptimo de capas, que proporciona una corriente de flujo de capas múltiples de por lo menos cuatro capas para el múltiple de un troquel anular; y un troquel anular que tiene por lo menos un múltiple de distribución que extruye una corriente de flujo de capas múltiples.
