A roller apron for a continuous casting installation, especially for casting steel strands, for supporting a partially solidified strand, which comprises a number of successive pairs of rolls which follow one another in the direction of travel of the strand. The bearings of at least one roll are arranged at a traverse or crosshead extending essentially parallel to the lengthwise axes of the rolls. The traverse can be applied against stops governing the format or cross-sectional thickness of the strand and coacting at both ends with pivotable levers articulated at the machine frame and at a movement device. The movement device comprises a power source interconnecting both of the pivotable levers. This power source applies at both pivotable levers force components which are effective essentially parallel to the roll axes and thus applies the traverse elastically against the stops in the direction of the strand and also allows the traverse to automatically move away from the stops in the presence of a predetermined load limit associated with the traverse.
