Abstract
A device and method for changing rolls in a roll stand. Each stand includes two working rolls, each having a backing up assembly including at least one intermediate roll. An adjustment structure is provided for adjusting levels in relation to the axes of each of the rolls with respect to the stand and for setting forth four levels of disassembly, respectively of both working rolls and both intermediate rolls. Two pairs of rails are provided parallel to the axes of the rolls arranged on the stand at two constant levels each at a level of disassembly and carrying sliding carrying members for removal of the corresponding intermediate roll. A handling device is placed on one side of the stand and includes at least one handling and guiding chassis carrying two pairs of rails aligned respectively with both pairs of rails on the stand. At least one extractor device is mounted to slide at a constant level on the guiding chassis. A carrying member is mounted on the extractor device to pick up each working roll with the level of the carrying member being adjustable. A removable mechanism is provided on the extractor device for hooking each of the intermediate rolls. The removable mechanism is actuated selectively.
