Abstract
A device for controlling an unwinding of a continually fed material web in a printing machine comprises a web storage to which the web is loaded from the unwinding roller and which includes a housing-fixed roller group and a movable roller group. An inlet and an outlet rollers of the housing-fixed roller group are rotation-angle coupled with each other. The web storage serves as a control device for controlling the peripheral speed of the unwinding roller in dependence on the speed of the draw-in device.
