Abstract: With a mixing and kneading machine (100), wherein a worm shaft (12) moves in a housing (10) in a rotating manner and moves back and forth in a translatory movement, receptacles for kneading elements (12) are distributed non-uniformly. It is thereby possible to equip the receptacles with varying numbers of kneading elements. Quick adaptation is also thereby possible. In one embodiment, the number of kneading elements even varies over the extension direction of the mixing and kneading machine (100).

Abstract: The invention relates to a mixing and kneading machine for continuous preparation processes, such as for producing granules, extruded profiles, or molded articles, such as polymer granules, polymer extruded profiles, or polymer molded parts, having a feeding and mixing device (12) and a discharge device (14), wherein the feeding and mixing device includes a housing (18), a screw shaft (34), and a connecting element (24), wherein the connecting element is arranged at a front side of the housing and is also connected to the discharge device, wherein a hollow interior is formed in both the housing and the connecting element, and the screw shaft extends, at least sectionally, in the axial direction through the interior of the housing and, at least sectionally, in the axial direction through the interior of the connecting element, and wherein a plurality of kneading elements (40), which extend from the inner circumferential surface of the housing into the interior, are provided in the housing, and wherein kneading
