EDGE WINDING PROFILED STRIP ON PAPER MACHINE ROLL

摘要

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 strip at the outer edge region thereof, and elongating the strip simultaneously with the winding thereof onto the inner roll body at a longitudinal portion of the strip which is spaced outwardly from the exterior surface of the inner roll body which is engaged by the inner region of the strip, for facilitating the curving of the strip while it is wound onto the inner roll body, the elongation of said longitudinal portion of said strip being brought about by pressing the strip at an outer exposed side surface region thereof simultaneously with the winding of the strip onto the inner roll body toward the turns of the strip which have previously been wound onto the inner roll body, with the outer side surface region which is thus pressed being spaced from the exterior surface of the inner roll body and with the pressing being carried out with a force which is sufficient to compress the strip against the previously formed turns thereof while deforming and elongating the strip at said longitudinal portion thereof, the longitudinal portion of the strip being in line with said outer side surface region thereof.
