   Der Arbeitsvorgang ist folgender : Das Blech, dessen Kanten zur Erzielung einer grösseren Schweissfläche abgeschrägt sein können, wird in bekannter Weise aus dem vor der weiteren Öffnung des Trichters aufgestellten Ofen in den Trichter hineingezogen. 



  Sobald das Blech beginnt, sich an der Schweissstelle zusammenzubiegen, dreht man den

 Lage. Hierauf wird der Kern in seiner Längsrichtung verschoben, so dass er mit seinem cylindrischen Theile zwischen die Rollen R gelangt, worauf er mittelst des Splintes   i   in dieser Stellung festgehalten wird. Auf diese Weise ist es erreicht, den Kern tief in einen verhältnismässig langen Trichter einführen zu können. Wenn das Rohr fertig ist, schaltet man   Kern   durch die umgekehrte Handhabung wieder aus, worauf ein neuer Blechstreifen eingezogen werden kann. 



   Erwähnt sei noch, dass man den Trichter auch aus einem Stücke herstellen könnte und dass nur an der Schweissstelle eine Rolle   R   unbedingt erforderlich ist. 



   PATENT-ANSPRÜCHE : 
1. Trichter mit einschaltbarem Kern zum Schweissen schmiedeeiserner Rohre, dadurch gekennzeichnet, dass an der Schweissstelle in der Trichterwandung je eine Rolle R angeordnet ist, welche sich mit ihrem Längsprofile dem Verlauf der Trichterwandung anpasst.

 EMI2.1
 



   The working process is as follows: The sheet, the edges of which can be beveled to achieve a larger welding surface, is drawn into the funnel in a known manner from the furnace set up in front of the further opening of the funnel.



  As soon as the sheet metal begins to bend at the welding point, it is turned

 Location. The core is then displaced in its longitudinal direction, so that its cylindrical part comes between the rollers R, whereupon it is held in this position by means of the split pin i. In this way it is achieved that the core can be inserted deeply into a relatively long funnel. When the pipe is ready, Kern is switched off again by the reverse handling, whereupon a new sheet metal strip can be pulled in.



   It should also be mentioned that the funnel could also be made from one piece and that a roller R is only absolutely necessary at the welding point.



   PATENT CLAIMS:
1. funnel with switchable core for welding wrought iron pipes, characterized in that a roller R is arranged at the welding point in the funnel wall, which with its longitudinal profile adapts to the course of the funnel wall.

 

Claims (1)

2. Trichter mit einschaltbarem Kern nach Anspruch 1, bei welchem der Korn in der Längsrichtung aufgeschlitzt ist, um denselben elastisch zu machen. 2. A funnel with an on-core according to claim 1, wherein the grain is slit in the longitudinal direction to make the same elastic. 3. Trichter mit einschaltbarem Kern nach Anspruch 1, bei welchem der Kern mittels eines Stieles verschiebbar an dem drehbar zum Ein-und Ausschieben des Kernes dienenden Hebel sitzt, zum Zwecke, den Kern tief in einen verhältnismässig langen Trichter einführen zu können. 3. A funnel with a core that can be switched on according to claim 1, in which the core is slidably seated by means of a stem on the lever which is rotatably used to push the core in and out, for the purpose of being able to insert the core deep into a relatively long funnel. 4. Trichter mit einschaltbarem Kern nach Anspruch 1, bei welchem die an der Schweissstelle in der Trichterwandung angebrachten Rollen R vorschiebbar angeordnet sind, um dieselben nachstellen und nach dem Innern des Trichters zu pressen zu können. 4. funnel with switchable core according to claim 1, in which the rollers R attached to the welding point in the funnel wall are arranged to be able to be pushed forward in order to readjust them and to be able to press them towards the inside of the funnel.
