The invention relates to a method for determining the detaching angle and/or detaching profile of a paper web. The paper web (1) travels through sequential guide devices (2, 3) and detaches from guide device (2) so that the paper web (1) deviates from a tangential angle from the detachment point (5.1) onwards and the detachment point (5.1) forms a detaching profile (5) in the transverse direction of the paper web, which profile is determined with the aid of pattern recognition.
L'invention concerne un procédé de détermination de l'angle de détachement et/ou du profil de détachement d'une bande de papier. La bande de papier (1) se déplace dans des dispositifs de guidage successifs (2, 3) et se détache du dispositif de guidage (2), de sorte qu'elle s'écarte d'un angle tangentiel par rapport à l'angle de détachement (5,1) vers l'avant et que le point de détachement forme un profil de détachement (5) dans le sens transversal de la bande de papier, ledit profil étant déterminé à l'aide d'une technique de reconnaissance de formes.
