A method of manufacturing, for a paper machine or the like, a roll which has a grooved exterior surface. An elongated strip is wound onto the exterior cylindrical surface of an inner roll body, this strip being initially straight and being curved when wound onto the inner roll body so as to conform to the curvature of the exterior surface thereof while successive turns of the strip engage each other, this strip having an inner edge region engaging the exterior surface of the inner roll body and an outer edge region distant from the inner roll body and having a thickness less than the thickness of the remainder of the strip so that the turns of the strip define between themselves at the outer edge region of the strip an elongated helical groove. While the strip is wound onto the inner roll body, a longitudinal portion of the strip which is spaced outwardly from the exterior surface of the inner roll body is elongated for facilitating the curving of the strip as it is wound onto the inner roll body. |
