PROBLEM TO BE SOLVED: To perform that a shape error of a rubber roller is satisfactorily reduced even when a feedback gain cannot be raised by a detection time delay of an external diameter.SOLUTION: An extrusion molding machine of a rubber roller includes: a feed-forward control instrument that outputs a command value of a feed rate of a core grid; an external diameter measuring device that measures an external diameter of the rubber roller extruded from an outlet of a cross head, and outputs an external diameter measured value; a reference input shift instrument that outputs a reference input in which a prescribed external diameter target value of the rubber roller is shifted; and a feedback control instrument in which a command value of a feed rate of the core grid that is output from the feed-forward control instrument is compensated so that the external diameter measured value of the rubber roller may agree with the reference input. |
