A device for stretching foil material and poster holder built with the device includes a guide element and a profile that can be moved and guided crosswise relative to its direction of extension. Two hollow profiles, which are open on their longitudinal sides, extend along the profile with the hollow profiles receiving the edges of the foil material to be stretched. A stretching element is included for stretching the profile crosswise in relation to its direction of extension in any direction in which the hollow profiles are located. The guide element is obliquely mounted on a frame or a structure, so that the profile can be moved or stretched in a transverse direction relative to the direction of extension and obliquely relative to the direction of stretching of the foil material which is to be stretched. The poster holder has at least one such device, which is mounted on a free-standing frame, or forms such a frame, or is mounted on a structure. The stretching profile can be moved and stretched transversal direction relative to its direction of extension and obliquely relative to the direction of stretching of the foil material that is to be stretched. The stretching forces are received solely by the device.
A device for tensioning tear-proof, sheet material equipped with cord seams, consisting of a guide element and a profile which is displaceably guided thereon in the transverse direction to its running direction and along which there runs at least one hollow profile open at its longitudinal side, for accommodating a cord seam of the sheet material to be tensioned, as well as with tensioning means for tensioning the profile transversely to its running direction in that direction in which the hollow profile is located, wherein the guide element is assemblable at an oblique angle on a frame or structure so that the profile in the transverse direction to its running direction may be displaced and tensioned at an oblique angle to the tensioning direction of the sheet material to be tensioned.
A device according to one of the preceding claims, wherein the tensioning profile is a drawn, square, aluminium tube on whose one longitudinal side there are formed out one or two open hollow profiles, and in whose inside there is introduced a steel tube as reinforcement.
