Abstract

Procédé et dispositif pour la fabrication par extrusion de profilés creux, en matière plastique. Dans ce dispositif, le corps profilé creux 1 extrudé en 2,3 passe dans un calibreur 4, à l'entrée duquel il est revêtu d'un film de fluide lubrifiant; ce calibreur 4 a une ou des rainures hélicoïdales intérieures 12 dont le fond est traversé d'orifices 13 et s'étend dans un bac 9 partiellement rempli d'un fluide réfrigérant 10 mis en dépression par une canalisation 11. On assure ainsi la répartition homogène du fluide de glissement le long du calibreur 4 et l'application du profilé extrudé 1 contre la paroi de celui-ci. Des contre-rainures 14 peuvent être prévues pour former calibre de perçage. Application : extrusion de tous profilés creux en matière plastique.
