Abstract
In a method and a device for position detection of a material web (), the position of the material web () is determined on the basis of a marking () provided thereon. This marking () is detected by a first sensor (), which emits a position signal () proportional to the position of the marking (). The material web () is furthermore detected by a second sensor (), which emits a signal proportional to the velocity of the material web () transversely to the movement direction (). An output signal (), which represents position-proportional values of the material web () even when the position signal () fails, is then calculated from the velocity signal () and the position signal ().
