Cold pilger rolling mill for cold forming a hollow into a strain hardened tube with a roll stand with rollers mounted pivotably thereon. Efficient milling of long hollows is enabled without reducing the quality of the manufactured tubes. The cold pilger rolling mill has an unwinding device, wherein the unwinding device is arranged and in the feed direction of the hollow is located in front of the front mandrel thrust block such that at the unwinding device a spindle being rotatable around an axis being perpendicular to the feed direction of the hollow with the hollow wound thereon is receivable and in an operation of the cold pilger rolling mill the hollow is unwindable and feedable between the chuck of the front mandrel thrust block and the mandrel bar into the feed clamping sledge and the roll stand.

The state of the art discloses cold rolling mills comprising a roll stand, at least one roll rotatably mounted to the roll stand, a feed clamping saddle for feeding a blank, and a first drive for the feed clamping saddle. Those cold rolling mills have ball spindle drives with a high rate of wear as the drive for the feed clamping saddle. In comparison the object of the present invention is to provide a cold rolling mill whose drive for the feed clamping saddle involves no or only very slight wear and which in addition permits a slow movement of the feed clamping saddle. According to the invention that object is attained by a cold rolling mill which has a direct electromechanical linear drive for the feed clamping saddle.
