Edge winding profiled strip on paper machine roll

Abstract From the Canadian patent

In a method of manufacturing for a paper machine, or the like, a roll having a grooved exterior surface the steps, of winding onto an exterior cylindrical surface of an inner roll body an elongated strip which initially is straight and which curves while being wound onto the inner roll body with an inner edge region of the strip engaging the exterior surface of the roll body while an outer edge region of the strip is distant from the roll body and has a thickness less than the thickness of the remainder of the strip so that when the turns of the strip engage each other after winding of the strip onto the inner roll body, a helical groove will be defined between the successive turns of the …
