Abstract
A pair of edging rolls for edging the flange edges of symmetrical steel sections, particularly I-girders. Each edging roll has a barrel engaging in the inner contour of the steel section and guiding the section, and two edging paths adjoining the barrel on either side and extending outwardly in a conical shape for the flange edges of the section. The edging paths are arranged at the outer circumference of bushings which are guided so as to be displaceable coaxially at both sides of the barrel on the roll body. The bushings have end faces which face one another and engage in annular recesses of the barrel.
