Abstract
A line for producing a cast film is disclosed having a slot die, a chill roll, an electrode assembly, an insulator assembly, a sensor device, and a control device. The electrode assembly is arranged between an impingement area of the cast film on the chill roll and a removal area. The insulator assembly is arranged between the electrode assembly and the chill roll shell. The sensor device continuously determines the left and right cast film edge. According to the determined left and right cast film edge the control device moves the insulator assembly in such a way that the insulator assembly is arranged: a) between the left end face of the chill roll and the left cast film edge; and b) between the right end face of the chill roll and the right cast film edge.
