Claims
- 1. A method for producing a multi-layer structure roller, comprising the steps of:
- inserting a tubular-shaped middle cylinder section, having a greater coefficient of linear expansion than a tubular-shaped metal-made outer cylinder section, inside of the tubular-shaped metal-made outer cylinder section located at an outer-most position;
- coupling the outer cylinder section and the middle cylinder section by using a difference in heat expansion caused when the outer cylinder section and the middle cylinder section are heated in a laminated state;
- providing tapers at an inner circumference of the middle cylinder section and at an outer circumference of a tubular-shaped inner cylinder section, the tubular-shaped inner cylinder section inside of the middle cylinder section;
- fitting the taper at the inner circumference of the middle cylinder section to the taper at the outer circumference of the inner cylinder section by expanding with heating the middle cylinder section, the taper of the inner cylinder section being at room-temperature; and
- combining the middle cylinder section and the inserted inner cylinder section, the middle cylinder section being cooled to room-temperature, while the tapers are fitted to each other.
- 2. The method producing the multi-layer structure roller according to claim 1, further comprising the steps of:
- attaching an elastic body to a surface on the outer circumference of the middle cylinder section; and
- coupling the outer cylinder section and the middle cylinder section by using a difference in heat expansion caused by the heating of both of the cylinder sections sandwiching the elastic body.
