摘要： A roll, of the type used in paper machines, is manufactured by rotating an inner roll body around its axis while simultaneously winding onto the outer surface of the inner roll body an elongated metal strip the convolutions of which press against each other so as to cover the outer surface of the inner roll body at the area of this outer surface onto which the strip is wound. This strip has an inner edge surface engaging the outer surface of the inner roll body, an outer edge surface distant therefrom, and opposed side surfaces extending between the inner and outer edge surfaces. At each of the wound convolutions of the strip the opposed side surfaces thereof respectively engage, over their entire areas, the adjoining side surfaces of adjoining strip convolutions over the entire areas of these adjoining side surfaces. At any instant during the winding of the strip onto the inner drum body, the strip has an end convolution an inner side surface of which presses against the immediately preceding convolution and an outer side surface of which is exposed at one end of the series of convolutions which have already been wound. A compressive force, which is directed parallel to the axis of the inner roll body, is applied against the outer side surface of this end convolution, during winding of the strip onto the inner roll body, at a location extending inwardly from the outer edge surface of this end convolution along the outer side surface thereof toward but terminating short of the inner roll body. The magnitude of this compressive force is sufficiently great to deform and elongate the end convolution at the location thereof to which the compressive force is applied.

摘要： 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.
