Abstract

This disclosure is directed to dismantling and assembling operations for work rolls and/or backup rolls, which may include backup rolls with an additional pair of bearing chocks for backup roll bending facilities such as employed in a 4-high rolling mill. The apparatus disclosed includes a pair of extractor cars horizontally displaceable towards and away from each other at spaced-apart locations. Displaced at right angles between these cars is a roll carriage having support saddles for carrying in a horizontal spaced relation a worn roll assembly and a refurbished roll assembly. The roll carriage has stop means employed to align at different times the rolls carried by the saddles in relation to travel of the extractor cars. The extractor cars have guides to assure their mutual alignment with respect to each other and with respect to a roll supported by the saddles.
