Abstract

Procedimiento y dispositivo para la obtención de estructura conformadas y compactas de mezclas de goma vulcanizables, en forma pulverulenta, con ayuda de una unidad de plastificación de tornillos sinfín, cuyo procedimiento se caracteriza porque la mezcla de goma pulverulenta se introduce primeramente a través de una bolsa de alimentación de actividad suministradora en la extrusionadora, a continuación se plastifica en una zona de mezcla, se compacta por combinación de las partículas de goma plastificadas y a continuación se conforma en forma plastificada y homogeneizada.
