Abstract

Se describe un dado de extrusion que incluye un primer miembro (14) que tiene una superficie que incluye una pluralidad de segmentos de canal espiral (36) formados en el mismo y un segundo miembro (16) que tiene una superficie que incluye una pluralidad de segmentos de canal espirales (37) formados en el mismo. Las superficies del primero y segundo miembros están colocados una con respecto a la otra para formar un espacio de derrame (24) entre ellas, en donde los segmentos de espiral del primero y segundo miembros están acoplados para formar una pluralidad de canales espirales que tienen líneas centrales que ondulan hacia atrás y hacia adelante a través del espacio de derrame. Un canal espiral está formado por un segmento de canal espiral en el primer miembro alineado con un segmento de canal espiral respectivos están sustancialmente a 90 degree C fuera de fase. Los segmentos de canal de espirales respectivos tienen una pluralidad de porciones de segmento de canal de espirales interconectadas (44, 45, 46, 47, 48, 49) cada una de las cuales se incrementa en profundidad desde su superficie hasta un punto de profundidad máxima y por lo tanto disminuye en profundidad de regreso a la superficie.
