ABSTRACT:
A web is threaded in the reeling of a paper or board web, by passing a web tail strip (W) into a reeling nip between a reeling drum (10) and a reel spool (12), on which a web roll is formed. The tail strip (W) is passed into the reeling nip by a suction zone (20) which extends substantially around the entire reeling drum circumference and is (10) in an area where a full-width web runs during reeling, so that the tail strip (w) can be conducted directly along the suction zone (20). The suction zone (20) is placed in the longitudinal direction of the reeling drum (10), i.e. in the width direction of the web.
