Abstract (en)
[origin: EP0692322A2] The blank during conversion is stretched, and tools for reducing the cross-section are moved on the blank in the direction opposite rolling, and the flutes of the tools have an inclination opposite to the desired inclination of the blank. The inclination of the mfd. cone is controlled by the rotational movement of the tool along with the speed of the longitudinal movement of the tool. <IMAGE>
