Abstract

a. Dispositif pour la mise en forme d'un produit en forme de bande avec des éléments de réglage disposés transversalement à des endroits fixes l'un à côte de l'autre sur la largeur de la bande, qui attaquent un mécanisme agissant sur celui-ci sur la largeur de la bande et au moyen desquels l'action du mécanisme est différemment influençable localement sur la largeur de la bande. b. Dispositif caractérisé par un jeu d'organes de commande 40, 240 reliés chacun à un elément de réglage 30, pourvus d'un entraînement commun 43, 243 accouplé par asservissement, avec un détecteur de position de ces organes, et un appareil de commande dans lequel sont introduites des données comportant des valeurs de mesure de position de la bande, et qui fournit des signaux pour les organes de commande. c. Dispositif applicable notamment à des machines à papier.at. Device for shaping a product in the form of a strip with adjustment elements arranged transversely at fixed locations one beside the other over the width of the strip, which attack a mechanism acting on it on the width of the strip and by means of which the action of the mechanism is differently influenced locally on the width of the strip. b. Device characterized by a set of control members 40, 240 each connected to an adjustment element 30, provided with a common drive 43, 243 coupled by servo-control, with a position detector of these members, and a control device in which are entered data comprising measurement values of the position of the web, and which provides signals for the actuators. vs. Device applicable in particular to paper machines.
