Abstract
In a web-forming machine, a threading tail is formed from the web. The threading tail is transferred to the production section (-) of the web-forming machine including a draw section (). Monitoring takes place of both the formation of the threading tail and its transfer to the draw point (). The holding point () and its environment that terminates the tail threading of the production section (-) in question are additionally monitored, in order to detect the threading tail at the holding point () and thus to determine the success of the tail threading.
