Abstract

A tube threaded onto a mandrel is introduced into the open end of an extruded hose in an open, hollow mould. The mould lis then closed and the hose is inflated to form the hollow body, whereby the tube is welded to the wall which it penetrates.

Description

Verfahren zum Einbringen eines Rohres in einen Hohlkörper aus Kunststoff Die Erfindung betrifft ein Verfahren zum Einbringen eines Rohres in-einen Hohlkörper aus Kunststoff nach DP Pat.-Anm. P 19 o7 828.5), bei dem der Schutz sich auf durchgehende Rohre bezieht-Das gleiche Verfahren ist auch bei Rohren anwendbar, die in den Hohlkörper hineinragen. Method for inserting a pipe into a hollow body made of plastic The invention relates to a method for inserting a pipe into a hollow body made of plastic according to DP Pat. P 19 o7 828.5), in which the protection is based on continuous Pipes relates - The same procedure can also be used for pipes that are inserted into the hollow body protrude.

Die weitere Ausbildung der Erfindung besteht somit darin, daß das auf einen Dorn aufgezogene Rohr in das offene Ende eines aus einer Düse ausgetretenen Schlauches innerhalb einer offenen Ilohlform eingeführt wird, worauf die Hohlform geschlossen und deflSchlauch zum Hohlkörper aufgeblasen wird, wobei das Rohr mit der von ihm durchstoßenen Wand verschweißt wird.The further embodiment of the invention is thus that the tube drawn on a mandrel into the open end of a tube that has emerged from a nozzle Tube is inserted inside an open Ilohlform, whereupon the hollow shape closed and the tube is inflated to the hollow body, the tube with the wall pierced by it is welded.

Es gehört auch zu der Erfindung, daß der Schlauch beim Aufblasen zum Hohl gefäß hohlkehlartig an das Rohr angelegt wird.It is also part of the invention that the hose for inflation Hollow vessel is placed on the pipe in the manner of a hollow.

Insbesondere durch diese Verbindung zwischen Rohr und Wapd des Hohlkörpers ergibt sich eine solche Verbindung,daß auch nur eine Wand durchstoßende Rohre fest in dem Hohlgefäß angeordnet sind.In particular through this connection between pipe and Wapd of Hollow body results in such a connection that only one wall penetrates Pipes are fixedly arranged in the hollow vessel.

In der Zeichnung ist ein Schnitt durch ein Hohlgefäß, das nach der Erfindung hergestellt ist, als Ausführungsbeispiel dargestellt.In the drawing is a section through a hollow vessel, which is after Invention is made, shown as an embodiment.

Durch den Boden 1 des Gefäßes ist das Rohr 2 in das Innere eingeführt. Der Boden 1 des Gefäßes umgibt das Rohr 2 an der Durchtrittsstelle mit einer Hohlkehle 3, durch welche das Rohr sicher in dem Gefäß gehalten wird.The tube 2 is inserted into the interior through the bottom 1 of the vessel. The bottom 1 of the vessel surrounds the tube 2 at the point of passage with a groove 3, by which the tube is securely held in the vessel.

Die Zeichnung läßt erkennen, daß das Verfahren auch dann angewandt werden kann, wenn das Rohr außenmittig, nahe an der Seitenwand angeordnet ist.The drawing shows that the procedure was then also applied can be if the tube is arranged off-center, close to the side wall.

Die Verbindungsstelle zwischen Rohr und Gefäßboden wird mit der Vorrichtung nach dem Hauptpatent herOe,tellt.The junction between the tube and the bottom of the vessel is made with the device according to the main patent.
