Abstract: 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.

Abstract: An information presenting device. The device is arranged to be capable of assuming a first flattened configuration, for transport or storage, and of assuming a second extended and hence self-supporting configuration. The device comprises at least two panels joined together along the respective edges of at least two of the panels such that the device, having assumed the second configuration, forms a hollow cylinder, and at least one locking member, arranged between the panels 4, for continuously adjustable locking of the device in the first or second configuration, the locking member comprising a first part and a second part, the first part being slidably connected to the second part and the locking member being self-locking by a friction band coupling formed between contact surfaces of the first part and the second part of the locking member.

Abstract: An information presenting device. The device is arranged to be capable of assuming a first configuration, in which the device is flattened for transport or storage, and of assuming a second configuration, in which the device is extended and hence self-supporting. The device comprises at least two panels 4, made of a rigid material, which are joined together along the respective edges of at least two of the panels such that the device, having assumed the second configuration, forms a hollow cylinder, and at least one locking member 6, arranged between said panels 4, for continuously adjustable locking of the device in said first or second configuration, the locking member 6 comprising a first part 8a and a second part 8b, the first part 8a being slidably connected to the second part 8b and the locking member 6 being self-locking by a friction band coupling formed between contact surfaces of the first part 8a and the second part 8b of the locking member 6.
