摘要:
A screw 12 for an extruder 10 rotatably supported on the cylinder of the extruder and carrying roll-heated rubber material supplied from a hopper port 13s provided at the rear part of the cylinder 11, wherein the height of the portion of the flight portion 12z of the screw 12 located below the hopper port 13s is set lower than the height of the flight portion 12a on the downstream side of the screw 12, whereby the pulsation of extruded matter can be reduced while maintaining a high discharge rate.
