The invention relates to a strip-casting machine for producing a metal strip. Said strip-casting machine consists of a pair of casting rolls (2, 3) arranged in side-by-side parallel relation, two small faces (4) and a machine tool table (5) that supports the two casting rolls (2, 3). Said small faces (4) can be exchanged by means of a small face exchanging device. The aim of the invention is to reduce the change-over time between two castings, to improve positioning of the small faces and to heat them until start of the casting process while improving the accessibility of the casting rolls for an exchange thereof and while further allowing an optimum inerting of the plant. To this end, the small face exchanging device is configured as a support element, especially as a support arm (9) for one small face (4). Said support arm (9) and said small face (4) can be displaced in one plane from a pressing position downwards and vice versa in an essentially parallel manner and at a distance to the sealing surface of the small face (4).
