Abstract
A path for retreating movement of a cross bar from a standby position between a drawing mold and a mold of the next step to the drawing mold for holding the workpiece drawn by the drawing mold and a path for advancing movement of the cross bar holding the workpiece to the mold of the next step are formed into an upwardly smoothly curved line, and raising of a blank holder for the drawing mold is stopped temporarily for a period until the workpiece is discharged from the drawing mold by the cross bar. The paths for movement of the cross bar includes no suddenly turning portion and hence, any vibration of the cross bar due to an inertia force is prevented. Even if the paths for movement of the cross bar associated with all the molds are established in the same form, it is avoided that the cross bar or the workpiece interferes with the blank holder in the drawing mold.
