<p>A cold pilger mill including a rolling mechanism for intermittently rolling a tubular material over a mandrel to a reduced-diameter pipe. A detector (74) is associated with the rolling mechanism for detecting the rolling phase in the rolling mechanism. A feeding mechanism (42) for feeding the material in the axial direction and a turning mechanism (64, 68, 70) for turning the material and the mandrel are respectively provided with their own motors (76, 78, 80, 82). A controller (72) is also provided to receive a signal from the detector (74) and supply operation signals to the respective motors (76, 78, 80, 82) of the feeding mechanism (42) and the turning mechanism (64, 68, 70) so that these mechanisms are operated at completion of each rolling stroke.</p> |
