Abstract: A method of elongating a tube (10) by way of a drawing ring (13), wherein, when elongating the tube (10), tensile forces are applied to an elongated tube portion (22) which has already passed through the effective drawing ring cross-section and that pressure forces are applied to a tube blank portion (11) which has not yet passed through the effective drawing ring cross-section, wherein the tensile forces are applied by a mandrel (16) which is positioned in the tube and which is connected to a front tube end in a form-fitting or force-locking way.

Abstract: A forming process for providing a shaft with splines in that the shaft is provided with splines in such a way that the complete tooth depth is ensured over the entire length to be provided with teeth and any distortions which may occur are minimized in the course of the pressing operation undertaken to provide the teeth. The forming process includes a second force directed against the operational force which is applied to the free end of the toothed shaft.
