A core locking device has members ( 25 ) for locking the device ( 17 ) to a winding core of a roll to be wound on a two-drum winder, advantageously to a core. The device ( 17 ) is placed on a slide arranged in connection with the two-drum winder, and moves, as winding progresses, with the center of the roll being formed along the slide. The device ( 17 ) has an actuator ( 20 ) to produce a counterforce for the force caused by the mass of the core locking device ( 17 ) in the changed position of the core locking device ( 17 ).
