A web storage is described comprising a new roller assembly which permits the rollers to touch the web successively rather than simultaneously. This reduces the web tension occurring upon acceleration of the rollers. Fig. 1 shows a conventional web storage. For filling the storage, carriage b, supporting the even numbered rollers 2 to 8, is moved vertically upward to position F. In this assembly, acceleration of the rollers leads to increased tensile forces when the rollers touch the web. The magnitude of those forces can be reduced by a roller assembly (Fig. 2) which is slightly inclined to the web plane, so that the rollers touch the web successively rather than simultaneously. Increased friction, if any, occurring in the carriage guide (not shown), can be eliminated by an assembly, according to Fig. 3.
