 Drehung der Handkurbel in der in Fig. 6 angegebenen Pfeilrichtung kann der Kern in die punktiert gezeichnete Lage zurück und wieder in die Arbeitsstellung gedreht werden. 



   Bei den gezeichneten   Ausführungsformen   erfolgt die Bildung der Vollstrangschicht in dem aus der Presse austretenden Hohlstrang dadurch, dass der oder die Kerne, deren Form und Querschnitt beliebig sein kann, zeitweilig entfernt werden. Werden die Kerne zurückbewegt, so entsteht durch den in der Presse herrschenden hohen   Pressdruck im austretenden Strang   eine

 denken, das Wesen der Erfindung ist   immer darin suchen,   dass in dem   ausgepressten   Materialstrang abwechselnd Hohlraum und Vollwand entstehen. 



   Selbstverständlich lässt sich das Verfahren für die Herstellung jedweder allseits geschlossener Hohlsteine beliebigen Materiales anwenden, gleichviel ob diese mit einem oder mehreren Hohlräumen durch Benutzung einer entsprechenden Anzahl von Kernen versehen werden.

 EMI2.1
 Rotation of the hand crank in the direction of the arrow indicated in Fig. 6, the core can be rotated back into the position shown in dotted lines and back into the working position.



   In the illustrated embodiments, the formation of the solid strand layer in the hollow strand emerging from the press takes place in that the core or cores, whose shape and cross section can be of any desired shape, are temporarily removed. If the cores are moved back, the high pressure prevailing in the press creates a in the emerging strand
 EMI2.2
 think that the essence of the invention is always to be found in the fact that hollow spaces and solid walls are created alternately in the extruded material strand.



   Of course, the method can be used for the production of any hollow blocks of any material that are closed on all sides, regardless of whether they are provided with one or more cavities by using a corresponding number of cores.



   PATENT CLAIMS:
 EMI2.3
 The strand of material emerging from the mouthpiece opening of the press is alternately full and hollow
Strand layers are generated.

Claims

2. The method according to claim 1, characterized in that the full strand layers in the exiting hollow strand are formed in that the core or cores provided for forming the cavities are removed from the mouthpiece at suitable time intervals.

3. The method according to claim 1 and 2, characterized in that the core or cores are temporarily removed from the mouthpiece by rotating or shifting into the part of the press head located behind the mouthpiece plate.

4. The method according to claim 1, characterized in that the extruded strand is separated at any distance at the full strand locations formed between the cavities.

5. The method according to claim l, characterized in that the ejected strand is trimmed in the middle of the full strand locations with removal of an intermediate strip. EMI2.4 are connected to one another in such a way that they can be moved together by a suitable lever mechanism attached to the outside.
