Abstract

L'invention concerne un dispositif pour réaliser des produits de pliage à l'aide de dispositifs de pliage transversal de largeur multiple et de cônes de pliage longitudinal, devant permettre de réaliser des produits de pliage de différentes épaisseurs, notamment des annuaires téléphoniques. Selon l'invention, à cet effet, il est prévu en fonction du nombre de produits pouvant être simultanément pliés transversalement, les uns à côté des autres, dans le sens axial du dispositif de pliage transversal, un nombre équivalent de plans superposés pour des cônes de pliage longitudinal. Chaque cône de pliage longitudinal est monté de manière à pouvoir être élevé et abaissé dans au moins deux plans.
