Abstract
A method and apparatus in ropeless tail threading in a multi-roll calender is disclosed wherein the threading tail is guided through the multi-roll calender in such a way that, before the multi-roll calender, the threading tail is guided first of all to the broke processing and then cut when the tail threading begins. The tail threading takes place in stages, so that at least once during the tail threading the threading tail in connection with the multi-roll calender is guided to broke processing and cut, after which the tail threading is continued, once the previous stage has succeeded.
