Abstract

L'invention concerne un appareil de pliage présentant un élément exothermique. Cet appareil permet d'obtenir, de manière stable, des articles finis bien pliés, même lorsque l'appareil fonctionne à haute vitesse. L'appareil (1) présente un élément exothermique (33) doté de plusieurs parties exothermiques séparées (38) contenant une composition exothermique agencée selon des zones de séparation (57) et constituant des parties d'étanchéité produites par l'agencement de moulages de compositions exothermiques (35) adjacents entre eux, sur une matière de base (40). L'appareil (1) permet de couvrir cette matière de base de matière de couverture (39), de réaliser l'étanchéité des périphéries des moulages (35) de la composition exothermique et d'effectuer le pliage de l'élément exothermique (33) grâce aux zones de division (57) utilisées comme ligne de pliage. L'invention est caractérisée en ce que l'appareil de pliage (1) présentant un élément exothermique est équipé d'une courroie sans fin (12) destinée à distribuer les parties exothermiques séparées (38), et positionnée à l'intérieur de l'appareil ; et équipé d'une plaque de guidage de pliage (2) relevée depuis une partie de bord extérieur latéral de la courroie sans fin (12) et s'incurvant le long de la direction de distribution des parties exothermiques séparées (38), de manière progressive, vers le côté de la paroi sans fin (12).
