ABSTRACT:
Embodiments of a leveler that may be controlled by a computer are provided. The leveler may include a top frame that has at least a first set of rolls mounted thereon. The top frame includes a plurality of operatively associated ball screw assemblies that enable movement of the top frame with respect to a bottom frame of the leveler. The bottom frame has at least a second set of rolls mounted thereon. The leveler may further include at least one motor operatively associated with the plurality of ball screw assemblies. The motor is designed to drive the plurality of ball screw assemblies to move the top frame. The motor may also have at least one operatively associated encoder configured for monitoring or communicating data associated with rotation of the ball screw assemblies. The leveler may also include at least one position transmitter configured for monitoring a position of at least a portion of the top frame relative to a position of at least a portion of the bottom frame.
