Abstract
A twin-shaft screw-type extruding machine comprises a casing, shafts driven to rotate in the same direction of rotation and mixing elements facing each other and associated in pairs, which are disposed non-rotatably on the shafts. Each mixing element is a disk connected with a shaft. Mixing wings are provided at equal angular distances on the fronts, facing each other, of the disk and in the vicinity of the latter's respective circumference. A mixing wing of a mixing element and a mixing wing of the associated mixing element interengage and rotate past each other, while leaving a gap.
