Abstract

PURPOSE:To prevent arc discharge between exposed electrode and casting drum, by detecting the position of a film edge immediately before or after it is fitted to the drum and by varying the relative distance between cap and drum. CONSTITUTION:Insulating tube 5 is fixed on both terminal sides of high-voltage- impressed electrode to cover them, and edge sensors 4, 4 are provided before and after and point at which film 11 comes into contact with casting drum 2. Vertical movement adjusting devive 7 is provided at least on either one of cap 1 or drum 2. The motor to drive pinion 9 is rotated forward or backward so as to maintain the electric output signal proportional to the edge position obtained by edge sensor 4 at a constant value. Thus, the edge position is controlled so that it comes at about 5mm inside the electrode covering.
