    Abstract: Control system for profile adjustment of a property on an elongated sheet material, such as a rubber, during the manufacturing thereof. The system can include two gauges disposed on the output side of the manufacturing apparatus, one gauge being movable between an edge and the center portion of the sheet and the other gauge being at the other sheet edge. The manufacturing apparatus has a first actuator for adjusting the property at one sheet end portion and a second actuator for adjusting the property at the other end portion. The first and second actuators together act to adjust the property across the entire width of the material including a central portion intermediate to the end portions. A third actuator adjusts the central portion property in relation to the end portions. The gauges are coupled to a controller that periodically activates the first and second actuators together with the gauges at the end portions and the third actuator separately with the one gauge at the center portion. The first and second actuators are energized, upon actuation, to restore the end portions to their respective target values. The third actuator is energized, upon actuation, by the controller means only when the difference between the central portion property and the property of one of the end portions deviates from a predetermined amount. When there is such a deviation the third actuator initiates an adjustment that returns the central portion to match the edge value.
