Abstract
A reel for photographic paper has a hollow cylindrical core and two disk-shaped flanges having centrally located extensions received in the respective end portions of the core. The inner side of each flange tapers outwardly in a direction from the periphery of the core toward the periphery of the respective flange. The extensions have ribs which penetrate into the inner surface of the core, and the core is further coupled to each flange by a rubber hose which surrounds the respective extension and is biased against the inner surface of the core by an endless helical spring which surrounds a conical end face of the corresponding extension.
