Abstract
A vertical strip storage device for bridging strip running interruptions in continuous strip production includes a supporting frame forming a looping tower. The continuous strip is looped around deflecting rollers mounted on upper and lower horizontal roller bridges. The roller bridges move synchronously and vertically, one above the other, toward and away from one another. The inherent weight of one roller bridge compensates for the inherent weight of the other roller bridge as a counterweight. A joint cable drive is used to move the roller bridges. One of the roller bridges is at the upward cable portion of the vertically deflected joint cable drive and the other roller bridge is at the downward cable portion of this vertically deflected joint cable drive. The joint cable drive includes pulley blocks supported in the upper region and in the lower region of the supporting frame. Each pulley block includes stationary rollers connected to the supporting frame and loose rollers connected to the respective roller bridges. A cable of each pulley block is guided to a cable drum such that when the cable drum rotates, the associated roller bridge moves.
