PURPOSE:To give the outside surface a specified temperature by heating for a short time and to lessen the temperature difference between the sides and the center, by forming the shaft part of a heating roll with a heat resistant resin. CONSTITUTION:Roll's structural body is made, for ex., SUS303 composed of a cylindrical member 1 and shaft member 2, and an intermediate member 3 formed by a heat resistant resin is provided at the sides of this cylindrical member 1 in order to couple the shaft member 2. It can also be constructed so that a shaft member 2' formed by heat resistant resin is directly coupled with the cylindrical member 1 without interposition of any intermediate member |
