Abstract (en)
[origin: EP0483599A2] The invention relates to an apparatus by means of which, to change the rolls, the chocks of the upper working roll can be supported on those of the lower working roll in such a way that the rolls rest freely one above the other and their shells do not touch. According to the invention, the chocks of one of the rolls are equipped with swivellable supporting levers which, in their normal position, engage around flanks of the opposite chocks and, during adjustments of the stand, are capable of sliding on the said flanks. To change the rolls, however, the upper working roll is raised together with its chocks in such a way that the spring-loaded supporting levers can swivel inwards and engage in grooves in the opposite chock and, during the lowering of the upper working roll, are supported against the base of these grooves. During the installation of a set of rolls, the upper working roll is likewise lifted and the supporting levers are then spread apart, for example by means of a drive or locking devices, so that, as the upper working roll is lowered, they slide past the groove supporting them and can come to rest against the flanks of the opposite chock. <IMAGE>
