Abstract:
A roll machine comprising:a roll including a roll body and an elastic layer located on a periphery of the roll body;a mating roll;at least one roll nip formed between the roll and the mating roll;the elastic layer having a radial thickness less than 8 mm,wherein a radial thickness of the elastic layer is selected such that a compressive stress distribution occurring in the roll during operation under an operating line load exerted on an operating roll nip geometry is substantially the same as a test compressive stress distribution in a test roll under a test line load, which is substantially similar to the operating line load, exerted on a test roll nip geometry, which is substantially similar to the operating roll nip geometry, wherein the test roll includes a fiber-reinforced material layer having a modulus of elasticity of 6,000 N/mm.sup.2 or more.
