In a method for winding hot-rolled strip (1), comprising - a decoiler mandrel (4), - at least one first pressing device (7), - at least one second pressing device (8), wherein the hot-rolled strip (1) is pressed from the first pressing device (7) and the second pressing device (8) toward the decoiler mandrel (4), the hot-rolled strip (1) is pushed or pulled away from the decoiler mandrel (4) between the first pressing device (7) and the second pressing device (8), thereby subjecting the hot-rolled strip (1) to a prebending step. The invention further relates to a device for winding hot-rolled strip (1).

La présente invention concerne un procédé d'enroulement d'un feuillard à chaud (1) au moyen d'un mandrin d'enroulement (4), d'au moins un premier dispositif de pression (7), et d'au moins un second dispositif de pression (8). Selon cette invention, le feuillard à chaud (1) est comprimé par le premier dispositif de pression (7) et par le second dispositif de pression (8) en direction du mandrin d'enroulement (4), puis il est ensuite comprimé ou étiré à l'opposé du mandrin d'enroulement (4) entre le premier dispositif de pression (7) et le second dispositif de pression (8), ce qui permet de le soumettre à un cintrage préalable. Cette invention concerne également un dispositif conçu pour enrouler un feuillard à chaud (1).
