| description | A process for producing tubes (1), in particular for use in heat exchangers, from at least one metallic strip on a rolling mill train, wherein the strip, on a rolling mill train, is provided with predetermined breaking points, deformed and brought together to form the tube and finally the tubes are torn off at the predetermined breaking points between two pairs of rolls having a speed difference. The process is improved, in terms of the tearing off of individual tubes, in that an areal compressive force (Ak) is applied to the tube at least at the moment of tearing off and a sufficient tearing force (Rk) is produced and transmitted to the tube to be torn off. |
