Control device for bar transfer comprising a lever driven in rotation about a fixed axis, an arm mounted rotating on the lever around an axis parallel to the preceding axis, the arm being further connected to the bar transfer by a catch-pin of axis parallel to the aforesaid axes, the lever and the arm having the same length between the axes in question, and a mechanism being provided to drive the arm at a relative angular velocity double that of, and in the opposite direction to that of, the lever, wherein there is provided a drive mechanism for the lever comprising a drive element with cycloidal trajectory to modulate the speed of rotation of the lever and thus of displacement of the bar.
