Abstract
A roll manufacturing method and roll, particularly for paper machines, wherein an inner roll body is surrounded by a strip having circumferential portions such as windings which engage and extend outwardly from an exterior surface of the inner roll body with the successive windings or circumferential strip portions engaging each other so that the engaging side surfaces of successive strip turns define an interface between themselves. The side surfaces of the strip are formed with registering grooves which thus define a bore extending across the interface, and an elongated interlocking member is situated in the latter bore so as to interlock the successive turns or circumferential strip portions against radial displacement outwardly away from the inner roll body. The interlocking member preferably has a fluid-tight sealing engagement with the groove surfaces which define the bore which receives the interlocking member, so that the interlocking member also forms a moisture barrier.
