Arrangement for threading of web in a pulp machine

Abstract

The invention relates to an arrangement for threading a pulp web (W) from the press section () of a pulp machine to the dryer () of the pulp machine. The arrangement comprises a closing tail threading belt () or the like, which is arranged to convey the narrow tail end (W) formed on the pulp web (W) inside the dryer (), where the tail threading cord travels outside the edge of the normal web line of the pulp web. The tail end (W) can subsequently be broadened into a normal-width pulp web (W). The arrangement further comprises means () for gripping the tail end (W) in order to bring the tail end inside/between a closing tail threading cord () or the like, whereby the gripping means () are arranged to function at the normal running speed of the pulp machine. The arrangement comprises means () by which the tail threading cord () can be moved inwards from its normal route, towards the pulp web, to travel essentially in the same line with the tail end formed on the edge of the pulp web before the tail end is conveyed inside the tail threading cord, and means () by which the tail threading cord () and the tail end (W) inside it can be moved back to the normal route located outside the edge of the pulp web before entering the dryer ().
