Abstract:
A paper, board or material web is wound in a winder of the two-drum type. Winding core (10) ends placed against each other are coupled to be on the same axis of rotation during winding by severing cuts (12U, 12N) which are formed in the ends (11A, 11B) of the winding cores (10) and which deviate from a perpendicular cutting line.
