Abstract
La presente invención se refiere a dispositivo coextrusor de expuma polimérica de pared triple, que comprende: Un cuerpo de extrusión centrado sobre un eje horizontal y formado con un pasaje central alargado comunicante en un extremo corriente arriba con una fuente de resina sintética espumable; un miembro central alargado coaxialmente dispuesto en dicho pasaje central y extendido en la longitud del mismo para desviar un flujo de dicha resina sintética espumable, siendo dicho medio central capaz de formar con dicho pasaje central una pared intermedia de una coextrusión de pared triple, teniendo dicho miembro central un extremo aguas arriba que forma con dicho pasaje central un primer pasaje de pared intermedia cónica divergente que se ensancha en una dirección aguas abajo para permitir un flujo de dicha resina sintética espumable que se expande y descomprima, comunicando dicho pasaje de primer pared intermedia con un segundo pasaje de pared intermedia inmediatamente aguas abajo del mismo y axialmente dividido en una pluralidad de segmentos de arco por una pluralidad de mallas de un araña dispuesta en dicho pasaje central para sostener dicho miembro central, flanqueando dicho segundo pasaje de pared intermedia a dicha araña en los lados aguas arriba y aguas abajo de la misma con respectivas porciones anulares, aguas arriba y aguas abajo, formadas entre dicho miembro central y dicho pasaje central, comunicando dicho segundo pasaje de pared intermedia con un tercer pasaje de pared intermedia cónicamente convergente inmediatamente aguas abajo del mismo formado entre dicho miembro de control y dicho pasaje central y estrechándose en una dirección aguas abajo para comprimir un flujo de dicha resina sintética espumable, dicho tercer pasaje de pared intermedia se comunica con un cuarto pasaje de pared intermedia cónicamente convergente inmediatamente aguas abajo del mismo formado entre dicho miembro central y dicho pasaje central y estrechándose en una dirección aguas abajo para adicionalmente comprimir un flujo de dicha resina sintética espumable para obtener una primer relación de compresión entre dicho segundo pasaje de pared intermedia determinando y el cuarto pasaje de pared intermedia, comunicando dicho cuarto pasaje de pared intermedia con un quinto pasaje de pared intermedia cilíndrica formado entre un extremo aguas abajo de dicho miembro central y dicho pasaje central y definiendo una primer porción de longitud de contacto para la adecuada plastificación, estabilización y control de la contrapresión de un flujo de dicha resina sintética espumable; un canal cilíndrico de pared interna formado en dicho miembro central y definiendo una segunda longitud de contacto coaxial con dicha primera longitud de contacto, siendo dicho canal de pared interna comunicante con un primer canal de alimentación inclinado por lo menos en parte en un ángulo agudo a dicho eje y conectado en su extremo aguas arriba a una segunda fuente de resina sintética para proveer un flujo de dicha resina sintética adaptado para formar una pared interna de dicha coextrusión a dicha segunda longitud de contacto; y un canal de pared externa cilíndrica formado en dicho cuerpo de extrusión hacia afuera de dicho pasaje de pared intermedia.
