TWO-RADIUS TESTING ROLLER Russian patent published in 2014 - IPC B24B39/04 

FIELD: machine building.

SUBSTANCE: roller comprises two deforming elements with the profile radius of 0.5-5 mm set with a shift in radial direction in respect to each other by the value of 0.01-0.1 mm both to the roller axis and from it. The distance between the tips of the deforming elements along the roller axis amounts to $$\mathrm{0,6}\dots 1\cdot \left(\frac{R_{pr1}+R_{pr2}}{2}\right),$$ where R_pr1 stands for the profile radius of the first deforming element, R_pr2 - profile radius of the second deforming element.

EFFECT: expanded process functionality.
