The invention relates to a method for operating a strip casting machine for producing a metal strip during which molten metal is continuously poured between two casting rolls ( 3, 4 ) that form a casting gap. Sealing plates ( 2 b) are provided for laterally delimiting the casting gap, whereby the sealing plates ( 2 b) are displaced during the casting operation in an oscillating manner transversal to the direction of the axis of the casting rolls ( 3 ) counter to the front surface ( 3 a , 4 a) of said casting rolls ( 3, 4 ). Said sealing plates ( 2 b) are displaced in an oscillating manner in and counter to the direction of the periphery (U<SUB>3 </SUB>and/or U<SUB>4</SUB>) of the casting rolls ( 3, 4 ), whereby displacement takes place in an alternating manner along one or the other casting roll edges ( 3 k and/or 4 k). Partial solidifications can, to a large extent, be prevented from forming and can be removed if need be. The produced metal strip has clean edges.
