Disclosed is a pultrusion method for producing a profiled preform or fiber composite-plastic component having cross-sectional portions that extend at an angle from each other from a plurality of semifinished products (1, 2, 3) in a quasi conti-nuous process. Said method comprises the following steps: - in order to produce the preform, a dispenser (11) discharges at least one multilayer semifinished product arrangement (HA) that is a combination of several webs of reinforcing fiber layers of a semi--finished product (1, 3) and at least one resin film or binder material (2), and said multilayer semifinished product arrangement (HA) is delivered to a shaping device (12); - the semifinished product arrangement is guided through a shaping device (12) in which at least one cross-sectional portion of the semifinished product arrangement is bent in order to form an angle section; the semifinished product arrangement (HA3) is pressed in a pressing device (13); after a hardening process and a cutting process, a longitudinal section of the preform or the component is removed. Also disclosed are a pressing device and a pultrusion system (P) for carrying out said methods.

L'invention concerne des procédés de pultrusion pour produire une préforme profilée ou un composant profilé en matière plastique renforcée par des fibres présentant des parties de sections transversales qui s'étendent en angle les unes par rapport aux autres à partir d'une pluralité de produits semi-finis (1, 2, 3) au cours d'un processus quasi-continu. Selon l'invention, pour la production de la préforme, au moins un ensemble semi-fini (HA) multicouche, comprenant une combinaison de plusieurs bandes de couches semi-finies de fibres de renforcement (1, 3) et d'au moins un film de résine (2), est distribué par un dispositif de distribution (11) et acheminé jusqu'à un dispositif de façonnage (12). L'ensemble semi-fini est ensuite guidé à travers le dispositif de façonnage (12), au moins une partie de section transversale de l'ensemble semi-fini étant courbée de manière à former un profilé angulaire, puis l'ensemble semi-fini (HA3) est comprimé dans un dispositif de pressage (13) et une section longitudinale de la préforme ou du composant est prélevée optionnellement après un durcissement et un processus de coupe. L'invention concerne en outre un dispositif de pressage et une installation de pultrusion (P) pour mettre en oeuvre ces procédés.
