摘要

Rolling stand which can be converted into a four-high stand or universal stand, comprising one pair of housing standards (13) mounted on a base plate (11). The housing standards are able to support a universal roll assembly (24) or a four-high roll assembly (25). The housing standards (13) are longitudinally movable and able to be reciprocally positioned at least in their working position on said base plate (11). The pair of housing standards permanently bears two main roll chocks (14) together with their devices (15) for adjusting the distance between the centres of the rolls. The adjusting devices (15) cooperate with inwardly projecting supports (16) being a part of the housing standards (13). The main chocks (14) support either the horizontal rolls (26) of the universal roll assembly (24) or the back-up rolls (35) of the four-high roll assembly (25). Either the vertical rolls (28) belonging to an universal roll assembly (24) or the horizontal work rolls (36) of a four-high roll assembly (25) are located within the interspace comprised between two main roll chocks (14) in the housing standards (13).
