Abstract (en)
[origin: DE19855652C1] Roll mounting (2) with rolls (1) in its vertical orientation is removed from roll stand and pivoted to horizontal position. Bearing blocks (3) are removed from their journals and placed into parking position, and then rolls are changed. Bearing blocks are installed on new rolls. Roll mounting is pivoted to original vertical orientation and returned to roll stand structure by transport unit. An Independent claim is given for the apparatus used to implement the process. The apparatus includes: device (I) for pivoting the roll mounting; device (II) for handling the bearing blocks; and multi-functional device (III) adaptable to different roll stand sizes for transporting the roll mounting and rolls.
