A kneading disk has a plurality of disk elements having flight tips arranged at a helix angle &#x3b8; in a direction supporting main streams of a resin. The flight tips of every two adjoining disks have a clearance formed therebetween. The resin is kneaded by undergoing dispersion and distribution without having any excessive temperature elevation in approximately three kinds of streams, i.e. its main streams flowing along the flight tips, its back streams through the clearances and its tip riding streams flowing over the flight tips.
