A method of manufacturing a two-layer roll having a foamed elastic layer
provided on a core, and an elastic layer provided on the foamed elastic
layer includes the steps of forming the elastic layer by use of a
cylindrical mold holding a first cylindrical member used to form the
outer cylindrical surface of the elastic layer, the first cylindrical
member being manufactured by means of machining a solid member; forming a
solid primary layer on the core by means of side extrusion; setting the
formed elastic layer and the core having the solid primary layer formed
thereon in a second cylindrical member of a foaming mold; and foaming the
solid primary layer into the foamed elastic layer to form the two-layer
roll having the formed elastic layer and the elastic layer.
