Abstract
A device for unwinding a web of material which is wound in a roll on a winding core is utilized in a roll changer of a printing press. An inner shaft carries a clamping cone and an outer, coaxial shaft carries a torque transmitting element. These two shafts are slidable axially independently of each other and can operate in concert to rapidly stop a rotating wound roll of material having a large mass. Large torques can be transmitted to the wound roll without causing damage to the wound material.
