EMI1.1
EMI1.2
mit erweiterten Hohlräumen mittels eines zweiteiligen Kernes, dessen einer Teil quer zur Längsachse verschiebbar ist. Es ist an sich bereits bekannt, Röhren ans plastischer Masse durch Einführung eines Kernes in ein feststehendes Gehäuse und Glättung der durch diesen erzeugten Mantelfläche mittels eines gleichachsigen, quer verschiebbaren Druckstückes her- zustellen. Dem Bekannten gegenüber unterscheidet sich der Erfindungsgegenstand dadurch, dass das Druckstuck von gleichem Durchmesser wie jener Teil des Kernes ist, gegen welchen es verschoben wird und dass es zur Herstellung der erweiterten Hohlräume der Röhre dient.
Die zur Ausführung des Verfahrens dienende Vorrichtung besteht aus einem zylindrischen Kern a und einem quer zu dessen Längsachse verschiebbaren, ebenfalls zylindrischen Druckstück b, dessen Durchmesser gleich dem des Kernes a ist.
Die Arbeitsweiso ist folgende : Kern a und Druckstück b werden konachsial in die Rohrform c eingesetzt. Hierauf wird in bekannter Weise Rohmasse in den Raum zwischen
EMI1.3
Röhre geformt. Durch geeignete Mittel, beispielsweise durch Keilwirkung, wird alsdann das Druckstück d quer zur Längsachse des Kernes a allmählich verschoben, wie in der Zeichnung in Fig. 1 im Längsschnitt und in Fig. 2 im Grundriss gezeigt ist, bis der erweiterte Hohlraum hergestellt ist.
Die Drehung des Druckstückes b kann gemeinsam mit dem Kern a oder unabhängig von demselben in beliebiger Weise erfolgen.

EMI1.1
EMI1.2
with enlarged cavities by means of a two-part core, one part of which can be moved transversely to the longitudinal axis. It is already known per se to produce tubes of plastic material by introducing a core into a stationary housing and smoothing the surface area created by this by means of an equiaxed, transversely displaceable pressure piece. The subject of the invention differs from the known in that the pressure piece is of the same diameter as that part of the core against which it is displaced and that it serves to produce the enlarged cavities of the tube.
The device used to carry out the method consists of a cylindrical core a and a likewise cylindrical pressure piece b, which is displaceable transversely to its longitudinal axis and whose diameter is the same as that of the core a.
The way of working is as follows: core a and pressure piece b are inserted conaxially into tube shape c. Then, in a known manner, the raw mass is placed in the space between
EMI1.3
Tube shaped. By suitable means, for example by wedge action, the pressure piece d is then gradually shifted transversely to the longitudinal axis of the core a, as shown in the drawing in Fig. 1 in longitudinal section and in Fig. 2 in plan, until the enlarged cavity is produced.
The rotation of the pressure piece b can take place together with the core a or independently of the same in any way.
