Abstract

PURPOSE:To obtain a heated roll device having an even distribution of temperature on the surface of the roll and the high strength with a simple constitution, by fixing a heat insulating member to a shaft, attaching the roll body in a slidable and rotatable way and adding a heat insulating wheel to the inner surface of the roll body. CONSTITUTION:A shaft 14 having a hollow inside structure is stuck into a side plate 13 by a screw 16 via a flange 15 which is formed in a body with the shaft part. A projected streak 17 is formed at the inside end of the shaft 14, and a disk-shaped heat insulating member 18 is fixed at the part of the streak 17. A low-friction member 19 is attached onto the outer circumference surface of the member 18. Then a roll body 20 formed into a cylinder is provided, and a hollowed part 21 to which the member 18 is fitted is formed across the body 20. A heat insulating wheel 22 fixed on the inner circumference surface of the body 20 is provided inside the part 21. A heater 23 is provided into the body 20 via a hollow part of the shaft 14.
