Abstract

La présente invention concerne un dispositif de fabrication d'une grille déployée qui supprime l'ondulation et la courbure d'une grille déployée jusqu'à ce que la grille atteigne un moyen de perforation d'ouïes à partir d'un moyen de déploiement, qui déploie un matériau en feuille principalement composé de plomb, dans le but de permettre que la grille soit transportée à plat vers le moyen de perforation d'ouïes. Le dispositif de fabrication de grille déployée comporte : un moyen de déploiement pour le déploiement d'une feuille en plomb ou en alliage de plomb ; un moyen de perforation d'ouïes permettant de créer, par perforation, des ouïes d'une grille déployée qui a été traitée par le moyen de déploiement ; un rouleau de changement de la direction de transport qui se situe à mi-chemin sur le trajet de transport de la grille déployée entre le moyen de déploiement et le moyen de perforation d'ouïes ; et deux rouleaux aplatisseurs installés verticalement qui sont situés sur le côté aval du rouleau de changement de la direction de transport et permettent à la grille déployée de passer entre eux. Le rouleau de changement de la direction de transport possède le diamètre le plus large au niveau de la partie centrale dans le sens axial du rouleau. En variante, le rouleau de changement de la direction de transport est conçu de sorte qu'une section intermédiaire formée entre la partie centrale axiale et les deux extrémités du rouleau possède le diamètre le plus large en des positions à égale distance de la partie centrale.
