Abstract
For unwinding of wound rolls, devices are known which have a frame composed of longitudinal girders and transverse girders and an unwinding beam mounted in the frame and which extends over the working width. On the unwinding beam two support beams are mounted so as to be transversely shiftable and carry at their free ends respective guide heads for insertion in the sleeve of a wound roll. The unwinding beam is suspended in the frame on tension means, especially cables which are raisable and lowerable by mans of a lifting drive. The pendulously movable suspension enables an automatic positioning of the guide heads in their insertion into the sleeve of a wound roll.
