ABSTRACT:
Existing roll housings are retro-fitted with a hydraulic drive by placing a sleeve with a collar in the bore that used to accommodate an adjusting spindle. The sleeve has a threaded extension on which is screwed a nut with a flange to which, in turn, the drive is releasably fastened. The sleeve is tension-biased in that the collar is urged against an internal shoulder. The piston rod traverses the sleeve and holds the mount for the upper roll.
