Slitting device and process for positioning a slitting device to slit a material web into partial webs. The slitting device includes a knife arrangement that is adapted for movement transversely to a web run direction of the material web and that includes a first knife attachment device positioned on one side of the material web and a second knife attachment device positioned on an other side of the material web. The first knife attachment device includes a drive with a positioning unit. The slitting device also includes a circuitless signal transmission path that is located between the first knife attachment device and the second knife attachment device and the second knife attachment device includes a follow-up device. The process includes contactlessly coupling the first and second knife attachment devices, and transversely moving the first knife attachment device across a width of the material web. The contactless coupling includes transmitting information related to the transverse movement of the first knife attachment device to the second knife attachment device, and the process further includes transversely moving the second knife attachment device in accordance with the transmitted information.
