Provided is a rubber-coated cord manufacturing technique with which the occurring of rubber spew can be prevented and waste in the form of
scrap can be reduced during a rubber-coated cord manufacturing step, and with which the burden on an operator can be reduced and a high-quality rubber-coated cord can be stably produced. This rubber-coated cord manufacturing device comprises: an
extrusion head that coats rubber on the surface of a cord, the
extrusion head including a screw rotation type extruder which extrudes rubber, an
insertion port into which the cord is inserted, and a flow path of rubber which has been extruded from the extruder; a cord supply device that supplies the cord to the
extrusion head; a rubber-coated cord winding device that winds a rubber-coated cord which has been coated with rubber by the extrusion head; and a head
pressure controller that controls the head pressure of the extrusion head. The head
pressure controller performs control to maintain the head pressure at a prescribed level by feeding back to the extruder the monitoring results of the head pressure while the cord is coated with the rubber, and adjusting the rotation speed of the screw.
