Abstract:
An apparatus for winding or unwinding material webs onto or from a winding core, comprising:a bearing device for the winding core; a drive; and a torque-transmitting device, coupled to the drive, for driving or braking the winding core rotatably mounted in the bearing device, the torque-transmitting device including a toothed-belt reduction gear mechanism operatively arranged between the drive and the winding core; wherein the torque-transmitting device ends with a drive gearwheel which is arranged on the bearing device in such a way that a winding core having a gearwheel engages with the drive gearwheel when said core is mounted thereon; and wherein the bearing device is mounted such that it can pivot about an axis of rotation, the bearing device being capable of assuming at least an insertion or removal position and a working position, wherein in the insertion or removal position the winding core can be fitted to or removed from the bearing device by moving the winding core in the horizontal direction into engagement with the drive gearwheel, and in the working position the winding or unwinding operation takes place.
