EXTRUSION MOLDING MACHINE FOR RUBBER ROLLER, AND METHOD FOR PRODUCING RUBBER ROLLER

摘要

PROBLEM TO BE SOLVED: To suppress the saturation of a control input and its periodically remarkable variation even if disturbance is remarkably varied in a long-term, and to stably reduce the shape error of a rubber roller.SOLUTION: The extrusion molding machine for a ruber roller comprises: a first controller for controlling the feed rate in such a manner that the outer diameter of a rubber roller agrees with the outside diameter objective value on the basis of the outside diameter measured value of the rubber roller; an estimator of outputting the low frequency components of the feed rate of the core grid; and a second controller of controlling the feed rate of a rubber material in such a manner that the average value of the feed rate of the core grid agrees with the average rate objective value on the basis of the low frequency components of the feed rate of the core grid.
