In an extruder equipped with a barrel 3 surrounded by a heating device, the head 6 has an opening 6a connected to the barrel 3 at its rear end, and its front end and lower surface are closed to form a storage chamber. 9 is formed, and in the storage chamber 9, the peripheral parts of an upper disk 14 having a center hole 14a and a lower disk 15 with no holes are arranged at equal intervals in the circumferential direction and at a constant angle. A rotating body 13 connected by a large number of vanes 16 that are inclined in the radial direction with a radius of The center hole 14a of the rotary body 13 communicates with the die 7, and a flexible movable strip screen 17 is provided on the outer peripheral surface of the rotary body 13, and the rotary body 13 rotates integrally therewith. The extruder is equipped with a movable screen which is brought into contact with the screen so as to allow both ends of the belt-like screen 17 to be guided outward through a passage cut in the front end of the head 6.
