The elastomer master batch is extruded onto the runner plate through an extruder, a screw and a machine head, and the machine head has the function of converting a material melt in rotary motion into parallel linear motion, uniformly and stably introducing the material melt into an inlet die and endowing the material with necessary forming pressure.
