Abstract

L'invention concerne une ligne d'extrusion de profilés en plastique, de préférence de tubes en plastique, comportant au moins une extrudeuse (1), un outil (2), un dispositif d'étalonnage (3) ainsi que d'autres dispositifs (4, 5) montés en aval. Selon l'invention, l'outil (2) au moins présente au moins un passage, un dispositif d'aspiration (6) est monté en amont de l'outil (2), vu dans le sens de l'extrusion (7), et l'outil (2) comporte plusieurs zones de fonctionnement avec des canaux de matière fondue séparés. L'invention porte également sur un procédé destiné à augmenter la puissance de refroidissement d'une ligne d'extrusion d'un profilé en plastique, notamment d'un tube en plastique, ce procédé comportant les opérations suivantes : a) fonte de matière plastique dans une extrudeuse (1), b) façonnage d'un boyau en plastique et amenée du boyau en plastique vers un outil (2), c) façonnage d'un profilé en plastique au moyen de l'outil (2) et d) étalonnage et durcissement du profilé par refroidissement dans un dispositif d'étalonnage (3), dans lequel le profilé (9) est refroidi intérieurement en plus du refroidissement externe. Selon l'invention, pour le refroidissement interne du profilé (9), l'air est aspiré dans le sens contraire au sens d'extrusion (7) par un dispositif d'aspiration (6), le boyau en plastique étant subdivisé en plusieurs parties dans l'outil (2) et la température de la matière fondue étant réduite avant la sortie de l'outil (2).
