Abstract

Dispositivo para regular el espesor de un parisón tubular de materia plástica, en una máquina de extrusión, por modificación de la sección de un canal anular comprendido entre una hilera (6; 6A; 6B; 6C) y un núcleo (7; 7A; 7B; 7C) dispuesto en el centro de la hilera, con ayuda de medios para provocar un movimiento axial relativo entre la hilera y el núcleo con el fin de obtener dicha modificación de la sección, en la que los medios para provocar el movimiento axial comprenden un motor eléctrico (25) rotativo, asociado con medios (12) para reducir el esfuerzo de arrastre y transformar el movimiento de rotación del motor (25) en movimiento lineal con el fin de provocar dicho movimiento axial relativo, caracterizado porque los medios para reducir el esfuerzo de arrastre y transformar el movimiento de rotación del motor en movimiento lineal, están constituidos por un colisón (12) biselado, arrastrado por el motor, porque la parte biselada del colisón está dispuesta entre una parte fija solidaria con el chasis (11) de la máquina y una parte móvil (17, 18A, 18B, 26, 70A, 70B, 70C, 28, 71A, 71B, 71C) móvil con el eje de desplazamiento relativo entre la hilera y el núcleo.
