Dans la position de base, la paire de cylindres de pliage et la lame plieuse se trouvent sur des côtés opposés de l'unité de transport et l'unité de transport possède un évidement dans lequel la lame plieuse vient en prise dans sa position de pliage. Le dimensionnement de la course de déplacement de la lame plieuse entre la position de base et la position de pliage et la détermination d'une association relative de la lame plieuse à la paire de cylindres de pliage sont tels que, dans la position de pliage, les cylindres de pliage sont écartés par la lame plieuse.
