A forging machine for reducing the cross section area of a workpiece which is positioned on the forging axis of the machine, i.e., the direction of travel of the workpiece through the machine. Four, forging saddles are arranged at intervals around the forging axis, a driving mechanism for each forging saddle and arranged to impart a thrust through its forging saddle in a lateral direction with respect to the forging axis. A guiding arm is associated with each driving mechanism an forging saddle for guiding the thrust of the forging saddle, each guiding arm being inclined at an angle to the direction of thrust of its associated forging saddle and being pivotally mounted about an axle which is parallel to the forging axis. Each forging saddle is adjustably connected to its guiding arm so that its position relative to the guiding arm can be adjusted either parallel to or transversely of the direction of thrust of the forging saddle. This arrangement enables the cross-sectional area of forged bars produced in such a machine to be adjusted.
