Abstract

Um beim Kaltziehen nahtloser Rohre, die Gefahr einer Exzentrizität mit einfachen Mitteln zu reduzieren, wird ein Dorn (1) mit einer entgegen der Ziehrichtung angeordneten Dornführung vorgeschlagen. Desweiteren wird vorgeschlagen, daß ein Ziehstein (2) und ein mit dem Ziehstein zusammenwirkender Dorn (1) in Abhängigkeit von der Exzentrizität des Rohres (3) in ihrem Relativwinkel zueinander verändert werden.
