The material to be mixed or kneaded enters an eight-shaped chamber 30, the shape of which is continuously fed via the inlet 14 and corresponds to the screw sections 31 and 32, which, after the correct mixing, exits through the output on the shafts 18 and 19 at the output end of the opening 38 . The main part of the kneader to be made are attached. The screw sections 31 of mixing and kneading are in the first stage in and 32 are shaped so that they are carried out continuously on one housing section 11 , and at the end of section 11 directed downstream and on the walls of chamber part 30 downward, the long strip.

Gaseous constituents released from shaped prongs 33 and 34 on the screw end section 31 and prongs 35 and 36 on the screw 30 can be freely provided through the vent opening 27. Step towards the clarity of the drawing. Prongs 33 and 34, which correspond to the ones shown in FIG. 2 are the various surfaces unmated, shown in abbreviated, spatula-shaped cross-section, but it is to be understood that the helical, continuously graze prongs 35 and shaped prongs 33-36 continuously along both 36, which have the same cross-section have and the radially inner and outer peripheral upper surface 35 in relation to the prongs 33 and 34 by 90 ° strips along surfaces of the chamber 26 as well as being offset on these.

Dabei besteht jedoch die Nei- zeigt speziell die Öffnungsplatte 13, die einen stromgung, daß ein Teil des in dem Mischer zu verarbei- aufwärts gerichteten Wandteil 24 besitzt, der ein Paar tenden Materials die Entlüftungsöffnung verstopft 65 hervorstehende Querschnittsverengungen 25 trägt, die oder sogar durch diese Entlüftungsöffnung nach außen sich von der Knetkammer 17 nach vorn erstrecken, und in das sich anschließende Entlüttungssystem tritt. Es können hier nicht gezeigte öffnungsgrößeneinstell-Aufgabe der Erfindung ist es, den Entlüftungs- ringe auf den Wellen 18 und 19 vorgesehen sein zurknown for example from US Pat. No. 3,501,807. The 60 mer 17 is open, and the housing section 11 is with The ventilation opening is used to provide a flange 1Od during processing, so that the opening to be mixed materials released gases plate 13 can be suitably attached to it. Fig. 3 derive to the outside. In this case, however, there is the ne- shows specifically the orifice plate 13, which has a current, that part of the wall part 24 facing upward in the mixer has a pair border material clogged the vent 65 carries protruding cross-sectional constrictions 25, the or even extend outward through this vent opening from the kneading chamber 17 to the front, and enters the subsequent remuneration system. There can be an opening size setting task not shown here the invention is to be provided on the shafts 18 and 19 for the ventilation rings
