L'invention concerne une installation de pliage d'éléments en matériau plat (10), cette installation comprenant un dispositif de pliage (12) dans lequel l'élément en matériau plat (10) est positionné avant le pliage sur un plan d'insertion (20), où il reste durant le pliage. L'installation comporte un dispositif de manipulation (14) doté d'axes de manipulation (52, 56, 58, 62, 66, 70) et permettant de réceptionner l'élément en matériau plat (10) en position d'alimentation (16), de l'insérer dans le dispositif de pliage (12) pour le pliage, de le sortir du dispositif de pliage (20) et de le mettre en position de stockage (18). L'invention vise à perfectionner le dispositif de pliage pour qu'il nécessite le moindre coût de conception possible. A cet effet, le dispositif de manipulation (14) est pourvu d'un axe de positionnement (76) présentant une précision de positionnement supérieure aux axes de manipulation (52, 56, 58, 62, 66, 70); l'axe de positionnement (76), lors du positionnement de l'élément en matériau plat (10) en au moins une position de pliage relative à une ligne de pliage (38) du dispositif de pliage (12), est parallèle au plan d'insertion (20) et parallèle à une ligne (77) transversale à la ligne de pliage (38); l'élément en matériau plat (10), lorsque les axes de manipulation (52, 56, 58, 62, 66, 70) sont fixés de manière rigide, est déplacé par l'axe de positionnement entre une position de mesure et la position de pliage.
