Abstract
A kneading segment kneads materials such that insufficiently kneaded portions would not remain as gel. The kneading segment is rotatably disposed on a kneading screw housed in a barrel having an inner cavity, and is provided with a kneading flight which kneads the material in the barrel by rotating according to the kneading screw's rotation. The top surface of the kneading flight is formed with a concaved cutout section. The cutout section is surrounded by two side surfaces, which face the axial direction, and a bottom surface, which is disposed between the side surfaces. The bottom surface of the cutout section is formed in a tilted planar shape in relation to the top surface. The opening of the cutout section, which faces one side of the rotational direction of the kneading screw, has a larger area than the opening which faces the other side.
