Apparatus for axially slidably positioning roll bearing supports in the housing window of a stand of a multiroll mill

An apparatus for axially slidably positioning at least two roll bearing supports guided in two housing windows of two stands of a roll stand pair of a many-roll rolling mill comprising:

• at least two supporting frames of a supporting frame pair with frame planes positioned substantially perpendicular to a rolling plane of said rolling mill and substantially parallel to each other on each stand;
• at least two traversing carriages each guided in a guide member mounted in each of said supporting frames, each of said guide members being pivotable about an axis oriented substantially transversely to the roll axis direction and each of said traversing carriages being drivable by one piston-cylinder unit whose one piston rod is seated or supported on the axis of said axis of said guide member having said traversing carriage and whose one cylinder combined radially with a guide sleeve for a rotatable bolt slidably mounted in said traversing carriage together with another of said piston-cylinder units whose other piston rod seats said rotatable bolt forms said traversing carriage;
• and
• coupling means for releasable engagement or for linkage of each of said traversing carriages with an associated one of said roll bearing supports comprising said bolt mounted in each of said traversing carriages which is insertable in and withdrawable from a recess in one of said roll bearing supports facing said traversing carriage.
