Abstract
A bending block for bending the rolls of cluster roll stands is rigidly connected on both sides of the chocks of the pair of rolls to be bent to the windowed housing posts of the roll housing or to units for the horizontal stabilization of the rolls. The bending block has bending jaws which are slidably guided in both bending directions and are driven by means of piston-cylinder units. The chocks or the units for horizontal stabilization have pressure receiving surfaces and the bending jaws have pressure contact surfaces which act on the pressure receiving surfaces in one or the other bending direction. Each bending jaw includes a pair of partial bending jaws which can be moved independently of each other and in opposite directions, wherein the pressure contact surfaces of each partial bending jaw corresponds to one or the other bending direction.
