ABSTRACT:
Equipment for leading a web threading tail in a paper machine has at least two sequential surfaces (11) in the direction of travel of the web threading tail (10), between which a nozzle (12) is arranged to form a directed air blast and thus to transport the web threading tail (10). The equipment has an element (13) in which an exhaust zone (20) is arranged in the surface (11) before the nozzle (12) in the direction of travel of the web threading tail (10), for leading air away from the element (13) between the web threading tail (10) and the surface (11).
