Winding device for a longitudinally cut material web and system for the controlled winding of a longitudinally cut material web

A device for winding a longitudinally cut material web comprising multiple longitudinal strips onto a plurality of winding tubes to form in each case a wound roll, comprising:

• an axle and, mounted on the axle, a plurality of ring-shaped winding drives that are individually controllable in their operating position and that are each adapted on their exterior to receive a winding tube for winding a longitudinal strip of the material web,
• each winding drive forming an external rotor electric motor and comprising a static interior tube and a rotatable external tube,
• the static interior tube being non-rotatably mounted on the axle and bearing, on its exterior, a stator having stator windings of the electric motor, as well as rolling bearings for receiving the rotatable external tube, and
• the external tube that is rotatable on the rolling bearings bearing, on its interior, a device for providing an excitation magnetic field that forms the external rotor of the electric motor, and comprising, on its exterior, a blocking device for the winding tubes to be received.
