ABSTRACT OF THE DISCLOSURE In sheet-rolling mills where the rolls are normally under maximum rolling pressure, the mill is said to be "pre-stressed." Load transfer blocks exert a force to relieve a part of the pre-stress for each particular strip rolling operation. This invention has a combination of hydraulic pressure and gas pressure for providing a controlled sub- stantially unyielding force during a rolling operation, and a yielding shock absorber for preventing full pre-stress load from coming on the rolls when an end of the strip passes the rolls or when a strip breaks.
