A twin-belt continuous casting mold has a mold chamber which is formed of parallel length portions of cooled upper and lower casting belts as well as parallel length portions of endless side dams which bound the mold chamber laterally. In the zone of the mold chamber the side dams are backed by adjustable guide rails. The continuous caster further has upper and lower caster frames which respectively support the end drums for the upper and lower casting belts as well as a series of support rollers for backing up the casting belts. There are further provided seals which are in engagement with the casting belts and which serve for sealing off the mold chamber from the environment. Opposite longitudinal edges of each casting belt are approximately flush with the outer wall faces of the respective side dams and the casting belt support rollers are shorter than the distance between the outer wall faces of the two side dams. The seals are situated laterally adjacent the support rollers and are resiliently supported.
