Abstract
La présente invention a pour objet un procédé pour la réception de feuilles ou plaques extrudées à leur sortie de la filière d'extrusion. Procédé caractérisé en ce qu'on fait défiler la feuille ou plaque extrudée entre deux lames d'air sous pression planes et parallèles aux pans de cette feuille ou plaque, lesdites lames formant coussins d'air et assurant à la fois le soutien, le guidage et le refroidissement de ladite feuille ou plaque, en amont des rouleaux de tirage habituels de ladite feuille ou plaque. Elle se rapporte à un procédé pour la réception de feuilles ou plaques extrudées à leur sortie de la filière d'extrusion et au dispositif pour sa mise en oeuvre.
