Abstract
A cassette assembly for a multi-roll leveler and a method for producing necessary work roll bending in such a cassette assembly. An upper and lower cassette module are provided for placement into a precision leveler. The lower cassette module is provided with roller support arms that lie below and transverse the work rolls of the module. The roller support-arms are pivotally connected to the lower cassette module near one side thereof. An actuator, or actuators, are integrally located in the lower cassette module to provide an upward force near the ends of the roller support arms opposite that of the pivotal connection. The upward force of the actuator(s) causes a resultant upward displacement of the roller support arms, and a corresponding bending of the work rolls of the lower cassette. The movement of the actuator(s) may be controlled and/or monitored by an automatic shape control system portion of the leveler to which the cassette assembly is installed.
