To provide a form rolling machine which is insusceptible to influence of "walk" by allowing a workpiece holding pedestal to slide in parallel to a rotating shaft of a roll die in accordance with the "walk" during form-rolling a workpiece sandwiched by the roll die.

In the form rolling machine 1 including a pair of roll dice 32, 42 and a workpiece holding pedestal 5 for holding a workpiece W, the workpiece holding pedestal 5 is slidably supported so as to be freely slide in parallel to the rotating shafts of the roll dice 32, 42 during form-rolling the workpiece W sandwiched by the pair of roll dice 32, 42. The form rolling machine 1 may include a forwarding device 6 moving forward and backward the workpiece holding pedestal 5 for the roll dice 32, 42, and a coupling device 7 for optionally coupling the workpiece holding pedestal 5 to the forwarding device 6.
