An improved apparatus for roll forming tooth profiles on workpieces is provided with an adjusting means for adjusting the root angle of a workpiece. The adjusting means is designed to withstand the large forces generated with equipment of this type and can be used in combination with a separate means for pivotally moving a die and a workpiece relative to one another for bringing the die and the workpiece into and out of meshing engagement. |
