摘要

PPROBLEM TO BE SOLVED: To provide a tire molding system provided with a method for controlling the winding of an extruded material from an injection molding machine, and the injection molding machine which can wind the extruded material such as a rubber strip stably and accurately onto a tire molding drum in the initial period of the injection of the extruded material. PSOLUTION: The rotation R of the tire molding drum 1 and the injection velocity V of the plunger of the injection molding machine 3 are increased respectively through a plurality of steps from the start of operation. In the first acceleration period in which the rotation of the drum 1 reaches the first constant rotational velocity R1 in the first step, the injection velocity V of the plunger of the injection molding machine 3 is controlled to increase at constant acceleration, and the rotation R of the drum 1 is controlled to increase along an acceleration target curve preset on the basis of the kind, physical properties, and injection capacity of the extruded material W.
