 EMI1.1 
 
 EMI1.2 
 aus einem Brett gefertigt, was den Nachteil hat, dass sie bei Feuchtigkeit und Temperaturwechsel rissig werden und sich verziehen. Infolgedessen mussten solche Siebe mit   unverhältnismässig   viel Spiel in die Dreschmaschinen eingebaut werden, wodurch   Körnerverluste   entstehen und die Ausgleichung der   zulassen   sowie der richtige Gang der Maschine leiden. Diese Nachteile sollen gemäss der Erfindung dadurch behoben werden, dass die Siebe aus sogenanntem Sperrholz, d. h. aus mehreren mit der Faser kreuzweise aufeinander geleimten Furnieren hergestellt werden. Solches Sperrholz wird zwar schon zur Herstellung der verschiedenartigsten Gegenstände benutzt, jedoch noch nicht zur Herstellung von Sieben. 



   Bei der Herstellung der Siebe wird die hölzerne Siebplatte (Blindholz) oben oder unten mit einem Fournier oder auch oben und unten mit je einem Fournier verleimt, wie in den Fig. 1 und 2 an zwei verschiedenen Sieben im senkrechten Schnitt und in Fig. 3 teilweise in Ansicht von oben, teilweise im Schnitt dargestellt ist.

 EMI1.2
 made from a board, which has the disadvantage that they crack and warp with moisture and temperature changes. As a result, such sieves had to be installed in the threshing machines with a disproportionately large amount of play, which results in grain losses and the compensation of the allow and the correct speed of the machine suffer. These disadvantages are to be overcome according to the invention in that the screens made of so-called plywood, i.e. H. can be made from several veneers glued crosswise with the fiber. Such plywood is already used to make all kinds of objects, but not yet for making screens.



   In the manufacture of the sieves, the wooden sieve plate (blind wood) is glued together with a fournier above or below or with a fournier each above and below, as in FIGS. 1 and 2 on two different sieves in vertical section and in FIG. 3 partially is shown in view from above, partially in section.
