    Abstract: In a papermaking machine, a method and mechanism for delivering stock to a dewatering web including a pressure headbox (10, 33) with a narrowing slice opening (21, 37), a receiving throat either with a single traveling forming wire (31) or a pair of traveling forming wires (11, 12), bridging the space between the headbox opening (21, 37) and the wire so that the stock jet is contained without a free surface, and applying a trailing flexible element (26, 35) opposite the stock in a single wire machine or against one wire in a twin wire machine with the force and location of the trailing element controlled by a series of push rods (27, 36) arranged parallel in a cross-machine direction.

    Abstract: Procédé et mécanisme pour machine de fabrication de papier, destinés à transporter et amener la pâte sur une bande d'égouttage comprenant une caisse de tête à pression (10, 33) présentant une ouverture à fente rétrécissante (21, 37), une gorge réceptrice ayant soit un seul fil métallique mobile de formation (31) soit une paire de fils métalliques mobiles de formation (11, 12), enjambant l'espace entre l'ouverture (21, 37) de la caisse de tête et le fil métallique de sorte que le jet de pâte est contenu sans surface libre, et un élément flexible arrière (26, 35) est appliqué à l'opposé de la pâte dans une machine à un seul fil ou contre un fil dans une machine à deux fils, la force et l'emplacement de l'élément arrière étant commandés par une série de tiges poussoir (27, 36) agencées parallèlement au sens transversal au sens machine.
