Abstract: 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.
