A chuck for winding cores onto which web-like material, such as paper etc., is wound, is longitudinally movable by a motorized drive. The chuck has a clamping core which grips into the winding core and is supported with a stop against its end face. The clamping core is longitudinally movable on a central part of the chuck and a compression spring is located between the central part and the clamping core so as to provide an axially acting clamping force on the winding core. The central part is provided with a switch actuatable by the longitudinally shifted clamping core to stop the motorized drive and achieve a relatively precisely adjustable clamping force. |
