<P>PROBLEM TO BE SOLVED: To provide an extruder for rubber roller capable of stably molding the rubber roller regardless of generation of burr on a rubber material around a core metal. <P>SOLUTION: The extruder 100 for rubber roller continuously feeds the core metal 1 into a crosshead 3, feeds the molten rubber material 2 into the crosshead, and extrudes a rubber organizer 7 through an exit 3a of the crosshead 3. The extruder 3 includes an outer diameter measuring instrument 10 measuring the outer diameter of the rubber organizer 7, and a core metal position calculator 13 measuring an end pass term that an end of each core metal 1 passes the outer diameter measuring instrument 10. A control system for controlling a speed at which at least one of the core metal 1 and the rubber material 2 is fed into the crosshead 3 performs feedback control by a first mode performed in a term other than the end pass term, and a second mode different from the first mode. Control by the first mode performed in the end pass term is performed in a term other than the end pass term. <P>COPYRIGHT: (C)2013,JPO&INPIT |
