  • the storage takes place in elevators, which are moved downwards with a growing stack. There are pile changes made.
  • the known device can be arranged in cascade, so that several bandwidths are served.
  • the known device is disadvantageous in that the storage length of the band is determined by the dimension of the rollers. The smaller the roll dimensions, the more kinks a web has. Straight kinks can lead to a deterioration of the fiber properties, especially since the deposited web still remains for some time in the packed form and may be burdened with other piles of webs.
  • the gripper mouth mimic creates impressions on the material that impair the appearance of the material surface.

It is essential that the conveyor belts on the web - whether guided or already stored - only unroll without creating friction. The tensile stress is negligible. In contrast, rollers stress the material web by tension, friction and slippage. The reduction in friction is especially important with regard to the deposition of the material web on the previous layer.
