Abstract
The process and the device which are the object of the invention relate to the cold rolling of tubes by means of a Pilger mill. The tube blank is made to advance near each of the upstream and downstream dead centers reached by the roll stand during its forward and return cyclical movement and backward movement of the rear part of the blank is made possible during a return pass of the roll stand. This process makes possible a doubling of production without changing the operating rate of the roll stand.
