Abstract

ABSTRACT OF THE DISCLOSURE

A method and device in a multi-cylinder dryer of a paper machine in the threading of the paper web, the threading taking place substantially without a system of threading ropes, which provides a reliable transfer and support effect for the leader is disclosed. The web is passed along a meandering path, in twin-wire draw, over drying cylinders and, in single-wire draw, on a drying wire over drying cylinders and leading suction cylinders or rolls. The leader is guided by means of air blowings extending across a substantial proportion or the whole of its width. The air blowings are applied from a doctor beam to an area proximate to the tip of the doctor blade at an acute angle in relation to the plane of the doctor blade.
