   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.

   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:
