Abstract

El presente invento proporciona una araña para un cabezal y herramental que utiliza guías de flujo curvado para dirigir el flujo de plástico a través del cabezal y el herramental. La pata de araña divide la corriente de plástico que fluye a través de la araña en dos corrientes independientes en el extremo ascendente. El extremo descendente consta de dos guías de flujo curvadas que están configuradas para dirigir las dos corrientes de plástico hacia un plano central longitudinal de la pata de araña. La turbulencia causada por las guías de flujo curvo crea líneas de soldadura obtusas o en ángulo agudo entre las dos corrientes de plástico. Estas líneas de soldadura obtusas y agudas en ángulo proporcionan enlaces más fuertes que las patas de araña conocidas que crean soldadura a tope o líneas de soldadura en ángulo recto.
