摘要： First screw (11) and second screw (12) each have small diameter portion (17a) having a diameter smaller than that of flight tip (11a, 12a), an axial position of small diameter portion (17a) of first screw (11) being the same as that of second screw (12), the present invention including first screw supporting portion (15a) having first supporting surface (25a) and second supporting surface (25b) that rotatably support small diameter portions (17a) of first screw (11) and second screw (12), and flow path (25c) through which resin material, which is transported by first screw (11) and second screw (12), passes.In the radial direction of first screw (11) and second screw (12), clearance Δ, which is formed between small diameter portion (17a) and each of first supporting surface (25a) and second supporting surface (25b), is equal to or less than the clearance, which is formed between flight tip (11a, 12a) and an inner surface of cylinder (13).

摘要： A multi-shaft kneading machine includes a channel and two screws rotatable around first axes of rotation. A pair of gate rods sandwich the two screws and are rotatable around second axes of rotation. Each of the pair of gate rods has two recess parts that form respective spaces through which the two screws penetrate. Each of the pair of gate rods has a first contact surface, which comes into surface contact with a screw when a gate rod is rotated to a minimum degree-of-opening position. Large diameter parts are fitted into the groove of the cylinder, and a small diameter part have a radius of curvature equal to half a distance between two second axes of rotation and smaller than a radius of curvature of the large diameter parts. The small diameter parts of the pair of gate rods are in contact with each other.
