Abstract
A kneading segment includes plural wing portions integrally formed along an axis such that angles, around the axis, of the plural wing portions are shifted. At a part of a leading end of each wing portion where a wing leading end surface and a wing surface connect with each other, a first flow surface facilitates flow of material between the wing leading end surface and the wing surface. At a part of a base end of each wing portion where a wing surface and a wing side surface of another wing portion adjacent to each wing portion connect with each other, a second flow surface facilitates flow of material between the wing surface and the wing side surface. Since such a configuration prevents material from staying between parallel kneading segments, impurities are prevented and will not mix into normally kneaded material.
