und im ersten, grössten Kaliber ai beispielsweise 1.
Das teilweise gestreckte Rohr M ! ist in Fig. 1 mit vollen Linien in der Stellung angedeutet, in welcher das Werkstück in das letzte, kleinste Kaliber aD tritt. In diesem Augenblick erstreckt sieh das Werkstück über eine Länge von etwa 6-7L, also auf eine Länge, die grösser ist als die Hälfte der ganzen Länge llL des Kaliberbettes. Dabei befindet sich das Werkstück gleichzeitig in elf Kalibern < ?,-a,.
Fig. 2 zeigt das Werkstück in dieser Stellung in grösserem Massstabe. Da die gesamte Anzahl der Kaliber der Stossbank im dargestellten Beispiel siebzehn beträgt, während die Anzahl der das Werkstück beim Eintritt in das kleinste Kaliber gleichzeitig bearbeitenden Kaliber elf ist, ist diese Zahl grösser als die Hälfte der Gesamtzahl der Kaliber.
Gemäss Fig. 1 befinden sich sämtliche Kaliber a1-a17 innerhalb einer Länge von llL, d. h. die

PATENT-ANSPRÜCHE :
1. Rohrstossbank zum Strecken von vorgelochten becherförmigen Luppen in einem Hub auf mindestens die zehnfache Länge mittels aus losen Rollen gebildeten Kalibern, deren Anzahl den Strekkungsfaktor übersteigt, dadurch gekennzeichnet, dass die Kaliber so nahe aneinandergerückt sind, dass sieh das Werkstück bei seinem Eintritt in das kleinste Kaliber mindestens auf das letzte Drittel der ganzen Länge der Kaliberreihe erstreckt und sich dabei gleichzeitig mindestens in einem Drittel der Gesamtanzahl der Kaliber befindet.

and in the first, largest caliber ai, for example 1.
The partially stretched tube M! is indicated in Fig. 1 with full lines in the position in which the workpiece enters the last, smallest caliber aD. At this moment the workpiece extends over a length of about 6-7L, that is to say over a length which is greater than half the entire length 11L of the groove bed. The workpiece is simultaneously in eleven calibers <?, - a ,.
Fig. 2 shows the workpiece in this position on a larger scale. Since the total number of calibres of the push bench is seventeen in the example shown, while the number of calibers simultaneously machining the workpiece when entering the smallest caliber is eleven, this number is greater than half the total number of calibres.
According to FIG. 1, all calibers a1-a17 are within a length of llL, i.e. H. the

PATENT CLAIMS:
1. Pipe push bench for stretching pre-perforated cup-shaped blanks in one stroke to at least ten times the length by means of calibers formed from loose rollers, the number of which exceeds the stretching factor, characterized in that the calibres are moved so close to one another that you can see the workpiece as it enters the smallest caliber extends to at least the last third of the entire length of the caliber row and is at the same time in at least one third of the total number of calibers.
