The present invention relates to a folding device (140) for folding of a blank for producing an information presenting device. The folding device (140) is arranged for receiving a blank (AB) with two opposite side edge portions (123a, 123b). The folding device (140) comprises two holding devices (141a, 141b) for holding the blank (AB) on each side of a folding line (VL). The holding devices (141a, 141b) is arranged for relative movement towards each other for folding the blank (AB) about the folding line (VL). The folding device (140) further comprises a compensation unit (142) which is arranged for displacement of the holding devices (141a, 141b) relative to each other during holding of the blank (AB). The compensation unit (142) is arranged for relative displacement of the holding devices (141a, 141b) such that the side edge portions (123a, 123b) are aligned relative to each other. |
