Abstract
A roller for the treatment of fiber masses for the textile industry has a sawtooth wire received in a rectangular cross section helical groove of a steel roll body and indented by a peening or indenting roller to provide, by plastic deformation of the foot portion, the outward forces which clamp the foot portion of the wire against the ribs flanking the groove of the roller body. As a consequence, the roller body as a whole is not deformed.
