ABSTRACT:
A heating roller apparatus with precise temperature measurement is disclosed which has a rotatable roller member comprising a cylindrical wall defining a room in the inside thereof and an annular groove therein, a heat source means, such as electrically excited induction coils, for heating the cylindrical wall, and a temperature sensor stationarily positioned in the annular groove of the cylindrical wall for measuring a temperature of the cylindrical wall of the roller member. The annular groove has an opening on the outer surface of the cylindrical wall, and two adjacent circumferentially extending wall faces which penetrate into the cylindrical wall in the direction substantially perpendicular to the rotating axis of the rotatable roller member. The annular groove is located at a part of the cylindrical wall adjacent to the end face of the roller member so that the outer surface of the remaining part of the cylindrical wall operates as a heat treating working surface.
