Abstract: A method for producing thing glass strips is provided that avoids camber defects. The method includes using a glass strip forming device that has a drawing device; drawing, using the drawing device, the thin glass strip away from the glass strip forming device; measuring, using a measuring device, variables that are dependent on a differing length of edges of the thin glass strip at at least two measurement locations spaced apart transversely to a longitudinal extension of the thin glass strip; determining a difference or a quotient of the variables. The difference or the quotient is used to determine a control variable by which the glass strip forming device is controlled so as to counteract a difference in velocities of the thin glass strip between the two opposite edges.
