To obtain a metal surface elastic roll which is capable of surface contact with a material to be contacted, can prevent the roughness and inadequate peeling of the surface of the material, in particular when used in processing and film making of a thermoplastic sheet or film, can surely perform the processing and film making, and can attempt the simplification, miniaturization, and cost reduction of an apparatus.
The constitution of a metal surface elastic roll 10 is, made multilayered structure having, from the peripheral side, a nearly cylindrical surface metal barrel 20, an elastic body 60, an intermediate tube material 30, and an inside tube material 40, the elastic body 60 is inserted between the metal barrel 20 and the intermediate tube material 30, they are heated to be bonded closely by the difference in heat expansion among these materials, and the intermediate tube material 30 and the inside tube material 40, with tapers 33, 43 brought together, are integrated by the contraction force generated when the temperature of the tube material 30 is restored to room temperature.
