1. A method for winding a material sheet with a winding device, wherein the material sheet is guided from at least one first roller to at least one second roller in a conveying direction, wherein at least one cutting device is arranged between the first roller and the second roller, wherein the cutting device cuts the material sheet into at least two partial sheets, wherein the partial sheets are each wound up into a bobbin in the conveying direction behind the second roller, wherein the at least one first roller and the at least one second roller are each driven by a drive in such a way that the tensile stress in the material sheet or in the partial sheets changes periodically over time in the conveying direction of the material sheet so that cutting edges of the partial sheets when wound up into the bobbin do not all lie on top of each other, but run variably.
