Abstract
Systems and methods directed to rolling mill coilers are disclosed. Systems and methods are disclosed for a control scheme to maintain a constant force between a roll and a coil's surface. Example systems and methods may include forming a portion of a coil, capturing a first coil data corresponding to force of the coil while the strip of metal is being rolled into the coil, capturing second coil data corresponding to position of the coil while the strip of metal is being rolled into the coil, determining a signal that corresponds to a roll force of the roll and a position of the protrusion, and transmitting the signal to a hydraulic cylinder coupled to the roll, the hydraulic cylinder causing the roll to exert the roll force counter to the radial force of the coil.
