Abstract

A device for storing and unrolling materials in web form in bookbinding machines having a roll-changing device for connecting a material which is to be unwound from a roll to the end of a material of the same kind unwound from another roll. The two rolls of material are placed, resting on their superficies, in an almost perpendicular shaft and are supported and guided on side walls of the shaft via their end faces. The roll of material to be stored rests on a stationary, almost horizontal floor. The unwinding roll of material rests on movable supporting elements which are set in motion, during the unrolling of the roll of material, when the latter is supported against supporting rollers forming one end face of the shaft.
