PATENTAMT.PATENT OFFICE.
Zur Herstellung von unrunden Röhren aus Zement u. dgl. sollen gemäß der Erfindung an . einer endlosen Gelenkkette befestigte Schaufeln Verwendung finden, die über ein größeres und ein kleineres Kettenrad laufen, welche beiden Kettenräder die vordere und hintere Kreisform bilden, während die seitlichen Bauchformen durch einstellbare Spannräder gebildet werden.For the production of non-round pipes made of cement and the like, according to the invention . Shovels attached to an endless link chain are used that have a larger one and a smaller sprocket run, which two sprockets the front and rear Form a circular shape, while the lateral belly shapes by means of adjustable tensioning wheels are formed.
ίο Eine Ausführungsform der Vorrichtung ist in der Zeichnung dargestellt, und zwar zeigt: Fig. ι einen Längsschnitt durch die Vorrichtung nach Linie A-B der Fig. 2,ίο An embodiment of the device is shown in the drawing, namely shows: Fig. ι a longitudinal section through the device according to line AB of Fig. 2,
Fig. 2 einen Querschnitt durch die Vorrichtüng nach Linie C-D der Fig. i,FIG. 2 shows a cross section through the device along line CD in FIG.
Fig. 3 eine einzelne Formschaufel.
Auf der Kernabdeckplatte α ruht ein Haupttriebrad b, welches von der Welle c gedreht
wird. Das Rad b ist als Kettenrad ausgebildet zum Bewegen einer Kette d, die über
ein Rad e läuft und durch Spannrollen f und g, die beliebig einstellbar sind, in Bauchform
gespreizt wird. An der Kette d befinden sich Schaufeln h, deren Seitenansicht aus Fig. ι
ersichtlich ist. Die Schaufeln laufen schräg abwärts und sind etwas gekrümmt, um die
plastische Masse unter Pressung gegen die Form wand zu schleudern.3 shows a single forming blade.
A main drive wheel b, which is rotated by the shaft c, rests on the core cover plate α. The wheel b is designed as a chain wheel for moving a chain d, which runs over a wheel e and is spread in a belly shape by tension rollers f and g, which can be adjusted as required. On the chain d there are blades h, the side view of which can be seen in FIG. The blades run diagonally downwards and are slightly curved in order to fling the plastic mass under pressure against the mold wall.
