Giessen, Einstampfen oder ein diesen ähnliches Verfahren unter Verwendung einer Form von entsprechendem Profil ermöglicht eine raschere und bequemere Herstellung als Drohen, Hobo ! n oder Feilen, da die letztgenannten Methoden in der Regel langwicriger, zeitraubender und demzufolge kostspieliger sind. Faserstoffe, welche einem geeigneten Verfahren unterworfen werden, bieten die Mög-

could be cast, but these screws were not suitable for use in aircraft due to their heavy weight.
Pouring, ramming or a similar process using a mold with a corresponding profile enables faster and more convenient production than threats, hobo! n or filing, since the latter methods are usually more tedious, time-consuming and consequently more expensive. Fibers, which are subjected to a suitable process, offer the possibility

In FIG. 1 of the drawing, one half of a two-part casting mold is shown in a view from above, and in FIG. 2 in longitudinal section; 3 and 4 show a finished air screw in two views. The production within the meaning of the present invention is as follows:

Twisted parts are placed between individual layers of fibrous material as a framework made of metal or hardwood - the most practical wire netting.
Propellers, which are subject to high mechanical requirements, are still completely or partially provided with a sheet metal casing and preserved

Fabrics are joined together with a binder by pressing or tamping using a shape corresponding to the propeller.
