Description

Verfahren zum Trocknen der gelöteten, nachlackierten Längsnaht von Konservendosenrümpfen Beim Löten der -Längsnaht von Konservendosen aus lackiertem Schwarzblech brennt der Lackfiberzug an der Lötstelle und in deren Nähe ab. Es ist deshalb- nötig, diese Stelle nachzulackieren. Damit die weitere Bearbeitung der _ Dosenrümpfe durch das Trocknen der Lackschicht nicht aufgehalten wird, ist es nötig, durch Wärmeeinwirkung, z. B. Anblasen mit heißen Druckgasen, auf die nachlackierte Lötstelle die Trocknung des. Lacküberzuges zu beschleunigen. Um zu verhüten, daß bei dieser Erwärmung durch Schmelzen des Lötzinns eine Entlötung der Rumpfnaht eintritt, wird nach dem Verfahren gemäß der Erfindung die Lötnaht an der Außenseite des Dosenrumpfes durch kalte Pressegase oder Kühlflüssigkeiten gekühlt, die man z. B. durch Düsen an die zu kühlende Zone heranführt.Method for drying the soldered, repainted longitudinal seam of Can bodies When soldering the longitudinal seam of cans made of lacquered Black sheet burns off the lacquer fiber coating at and near the soldering point. It is therefore necessary to repaint this point. So that the further processing of the _ Can body is not stopped by the drying of the lacquer layer, it is necessary, by the action of heat, e.g. B. Blowing with hot compressed gases on the repainted Soldering point to accelerate the drying of the lacquer coating. To prevent that With this heating up by melting the solder, the fuselage seam becomes desoldered, according to the method according to the invention, the solder seam on the outside of the can body cooled by cold press gases or cooling liquids that can be used e.g. B. by nozzles to the zone to be cooled.
