Verfahren zur Herstellung von AriiUeriegeschossen aus ineinandergesteckten Rohren.

bestimmten Lage festliegt
Praktisch wird das Verfahren in der Weise ausgeführt, dass das in fertige Länge geschnittene, innere Rohr in das in fertige Länge geschnittene äussere Rohr gesteckt und auf den ersten Walzenstuhl unter Festlegung der Lage des inneren Rohres zu dem äusseren Rohr das letztere auf das innere Rohr aufgepresst wird. Ist das innere Rohr in dem ausseren Rohr befestigt und in seiner Lage gesichert, so durchlaufen die beiden so in- einandergesteckten Rohre eine weitere Anzahl von Walzen, welche das äussere Rohr noch mehr auf das innere Rohr aufpressen.
Hiebei sind die hintereinandergeschalteten Walzen derart eingestellt, dass das äussere Rohr allmählich auf das vorgeschriebene Kaliber durchgewalzt wird. Die letzten Walzen können hiebei genau, wie es in der Patronenfabrikation

Nach vorliegendem Verfahren ist die Ausführung des Geschosses derart genau, dass nennenswerte Abweichungen in den Massen und Gewichten nicht vorkommen ; dadurch wird, genau wie beim Infanteriegeschoss, die Treffsicherheit bedeutend erhöht. Ausserdem ergibt sich, dass das Geschoss in seiner vollen Länge im Rohr aufliegen kann.
Da es in sels) ex vollen Länge glatt kalibriert ist, also grobe Drehriefen nicht enthält, so kann das Ge- J Jtzrohr sich nur in viel geringerem Masse abnutzen, umsomehr als das Geschoss nun nicht mit seinem Gewicht auf einer schmalen Reibungsfläche aufliegt und mit der vollen

Die neue Herstellung geschieht ohne alle die vorerwähnten älteren, vielfachen Arbeitgänge, Kontrollen und Materialverschwendungen.
Beim Zusammensetzen worden die auf ihre bestimmten Längen geschnittenen Rohre durch Dorne oder abgesetzte Scheiben in ihren gewünschten Abstand gebracht. Bei de durch äusseren Druck erfolgenden Befestigung der Rohre findet gleichzeitig eine Vergütung des Aussenrohres durch. die Komprimierung statt, wodurch noch eine höhere Festigkeit des Materiales erzielt wird.

certain location
In practice, the method is carried out in such a way that the inner tube cut to the finished length is inserted into the outer tube cut to the finished length and the latter is pressed onto the inner tube on the first roller frame, determining the position of the inner tube in relation to the outer tube becomes. If the inner tube is fastened in the outer tube and secured in its position, then the two tubes inserted one into the other run through a further number of rollers, which press the outer tube even more onto the inner tube.
The rolls connected in series are set in such a way that the outer tube is gradually rolled through to the prescribed caliber. The last rollers can do exactly as they do in cartridge manufacture

According to the present method, the execution of the projectile is so precise that there are no noteworthy deviations in the masses and weights; As with the infantry bullet, this significantly increases accuracy. In addition, the projectile can rest in its full length in the tube.
Since it is smoothly calibrated to its full length, i.e. does not contain rough turning marks, the barrel can only wear out to a much lesser extent, all the more as the weight of the bullet does not rest on a narrow friction surface and with the full

per MtM many times over.
The new production takes place without all of the aforementioned older, multiple operations, controls and material wastage.
During assembly, the tubes, cut to their specific lengths, are brought into the desired spacing by means of mandrels or offset discs. When the pipes are fastened by means of external pressure, the outer pipe is also remunerated. the compression takes place, whereby an even higher strength of the material is achieved.
