PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren nebst zugehöriger Vorrichtung zur Herstellung von solchen Rillen an Ton- oder Steinzeugröhren, welche, wie bekannt, ein Abheben der Dichtungsmassen unmöglich machen. Hierzu eignen sich am besten Rillen mit schwalbenschwanzförmigem Querschnitt.The invention relates to a method and associated device for the production of such grooves on clay or stoneware pipes, which, as is known, a lifting of the sealing compounds to make impossible. The best way to do this is to use dovetail-shaped grooves Cross-section.
Bisher sind nur Platten mit schwalbenschwanzförmigen Rillen hergestellt worden.So far only plates with dovetail grooves have been produced.
ίο Mit dem hierbei gebräuchlichen Verfahren ist jedoch die Herstellung von Rillen mit schwalbenschwanzförmigem Querschnitt bei gewölbten Flächen nicht angängig.ίο With the usual procedure for this however, the production of grooves with a dovetail cross-section in the case of arched ones Areas not accessible.
Der Erfindung gemäß werden die Röhren an den Dichtungsflächen zuerst mit Rillen von rechteckigem oder nach unten sich verengendem Querschnitt versehen; sodann werden die zwischen den Rillen verbleibenden Stege durch eine keilförmge Vorrichtung auseinandergedrückt, so daß der Querschnitt der Rillen nach außen hin verengt wird.According to the invention, the tubes are first grooved on the sealing surfaces rectangular or downwardly narrowing cross-section; then the between the ridges remaining in the grooves pressed apart by a wedge-shaped device, so that the cross-section of the grooves is narrowed towards the outside.
In der Zeichnung sind die verschiedenen Stufen bei der Herstellung eines Rohres mit schwalbenschwanzförmigen Rillen nebst einer geeigneten Vorrichtung zum Auseinanderpressen der Stege veranschaulicht.In the drawing are the various stages in the manufacture of a pipe with Dovetail grooves together with a suitable device for pressing apart illustrated by the webs.
In die Ton- oder Steinzeugmasse 1 werden Rillen 2 in bekannter Weise eingeschnitten oder eingedrückt (Fig. 1). Die zwischen den Rillen stehengebliebenen Stege 3 werden sodann mit einem an sich bekannten walzenförmigen Werkzeug 4, das Rippen 5 mit dreieckigem Querschnitt trägt, gespalten und auseinandergedrückt, so daß die Rillen einen schwalbenschwanzförmigen oder wenigstens einen sich nach oben verengenden Querschnitt erhalten (Fig. 2). Zweckmäßig werden hierbei die Rippen 5 so gestellt, daß der Abstand ihrer Mittellinien gleich dem Abstande der Mittellinien der Stege 3 ist.In the clay or stoneware compound 1, grooves 2 are cut in a known manner or pressed in (Fig. 1). The stays 3 between the grooves are then with a known roller-shaped tool 4, the ribs 5 with triangular Cross-section wears, split and pushed apart so that the grooves one dovetail-shaped or at least an upwardly narrowing cross-section obtained (Fig. 2). The ribs 5 are expediently placed so that the distance its center lines is equal to the spacing of the center lines of the webs 3.
