The invention provides a method and device for position detection of a moving material web. In a method and a device for position detection of a material web (2), the position of the material web (2)is determined on the basis of a marking (13) provided thereon. This marking (13) is detected by a first sensor (4), which emits a position signal (33) proportional to the position of the marking (13).The material web (2) is furthermore detected by a second sensor (5), which emits a signal proportional to the velocity of the material web (2) transversely to the movement direction (8). An output signal (7), which represents position-proportional values of the material web (2) even when the position signal (33) fails, is then calculated from the velocity signal (54) and the position signal (33). 提供了用于移动材料网的位置检测的方法和设备。在用于对材料网(2)进行位置检测的方法和设备中，基于在材料网(2)上提供的标记(13)来确定材料网(2)的位置。这个标记(13)由第传感器(4)检测，第传感器(4)发射与标记(13)的位置成比例的位置信号(33)。材料网(2)还由第二传感器(5)进行检测，第二传感器(5)发射与材料网(2)的横向于移动方向(8)的速度成比例的信号。然后即使当位置信号(33)失效时也表示与材料网(2)的位置成比例的值的输出
