Equipment for leading a web threading tail in a paper machine has at least two sequential surfaces () in the direction of travel of the web threading tail (), between which a nozzle () is arranged to form a directed air blast and thus to transport the web threading tail (). The equipment has an element () in which an exhaust zone () is arranged in the surface () before the nozzle () in the direction of travel of the web threading tail (), for leading air away from the element () between the web threading tail () and the surface ().

Equipment for leading a web threading tail in a paper machine

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 () and a reel spool (), on which a web roll is formed. The tail strip (W) is passed into the reeling nip by a suction zone () which extends substantially around the entire reeling drum circumference and is () 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 (). The suction zone () is placed in the longitudinal direction of the reeling drum (), i.e. in the width direction of the web.
