Apparatus for changing rolls of a straightening machine

摘要

An apparatus changes rollers of a straightening machine. The straightening machine contains a plurality of cantilever roller shafts for receiving the rollers. The apparatus contains at least a trolley having a device for supporting an entire set of upper and/or lower rollers to be installed in or taken off from the straightening machine. The apparatus further has at least two vertical plates spaced apart horizontally, a device for releasably securing the plates to the trolley, and an actuator connected to the plates and intended to be received in first passages defined in the straightening machine. The actuator is able to reversibly displace the plates and the trolley between a first position wherein the plates and the trolley are close to the straightening machine and a second position wherein the plates and the trolley are spaced apart from the straightening machine.
