   In der anliegenden Zeichnung ist beispielsweise der letzte Flügel einer doppelgängigen   Treibschnecko   dargestellt, und zwar ist :
Fig. 1 eine Seiton-und 
 EMI2.1 
 
Fig. 3 eine Oberansicht und
Fig. 4 ein Querschnitt nach Linie R R in Fig. 1. 



     Die beiden Flügel, welche   sich als je ein halber Gewindegang darstellen, schliessen sich mit den Rückenflächen b b'in bekannter Weise an die   Nabe t.   an, dagegen sind die vorderen Druckfächen a a'bis zur Mitte der Nabe geführt, so dass eine todte Fläche 
 EMI2.2 
 als Treibschnecke auftritt und der Thonstrang noch vor dem Verlassen des letzten Schneckenflügels eine Umformung erfährt, welche die Bildung eines Hohlraumes in der Thonmasse   verhütet.

   In the accompanying drawing, for example, the last wing of a double-flighted propeller screw is shown, namely:
Fig. 1 a Seiton and
 EMI2.1
 
Fig. 3 is a top view and
FIG. 4 shows a cross section along line R R in FIG. 1.



     The two wings, which are each represented as half a thread turn, close with the back surfaces b b ′ in a known manner on the hub t. on, on the other hand, the front pressure surfaces a a 'are led to the center of the hub, so that a dead surface
 EMI2.2
 occurs as a driving screw and the clay strand undergoes a deformation before it leaves the last screw wing, which prevents the formation of a cavity in the clay mass.
