Abstract

Plate width and roll diameter input signals are translated into roll and bending force spring constant representations which are multiplied by total roll and bending force signals, respectively, and added to desired roll and crown representations to produce a crown error signal. The error signal is proportionally integrated to provide a bending force reference signal which is employed to develop the proper roll bending forces to produce the desired crown.
