Claims

[Scope of utility model registration request]

A roll processing device for rolling a fillet portion of a workpiece, the first roll having a single contact surface contacting approximately the center portion of the fillet portion; and a second roll having two abutment surfaces that abut on the outside and whose abutment positions change between the center side and the outer edge side of the fillet portion as the fillet rotates. A roll processing device for the fillet section.
