The invention relates to a device for bending flat semi-finished products into a profile having a changeable cross-section along the length thereof, comprising at least one roll stand having profiling units in form of rollers and/or matrices. The semi-finished product can be led lengthwise between the profiling units. The invention further comprises at least two linear actuators (10, 12, 14, 16), arranged transversely to the length (Z) of the semi-finished product in order to produce translatory movements of the roll stand and rotational movements of the roll stand about an axis (Y) thereof. According to the invention, each of the at least two linear actuators are connected to the roll stand at a point provided at a distance from the axis (Y) of the roll stand.

L'invention concerne un dispositif pour le cintrage d'un produit semi-fini plat en un profil avec une section variable sur sa longueur, avec au moins un cadre de laminage, lequel présente des dispositifs de profilage se présentant sous la forme de rouleaux et/ou de matrices, entre lesquels le produit semi-fini est apte à être introduit selon la longueur, et avec au moins deux actionneurs linéaires (10, 12, 14, 16), lesquels pour la production de mouvements de translation du cadre de laminage sont disposés transversalement à la longueur (Z) du produit semi-fini, et, de mouvements de rotation du cadre de laminage, autour d'un axe (Y) de celui-ci. Selon l'invention, chacun au moins des deux actionneurs linéaires présents est articulé sur le cadre de laminage sur l'axe (Y) du cadre de laminage.
