（従来の技術）
アルミ材等の金属箔を金属箔圧延機で圧延する際には、
金属箔の幅方向形状を検出する必要がある。(Conventional technology) When rolling metal foil such as aluminum material with a metal foil rolling machine,
It is necessary to detect the shape of the metal foil in the width direction.

する部分の荷重を検出するセンサ７が埋込まれている。A shape detection roller 4 is arranged between the outlet side of the rolling mill 1 and the take-up reel 3 so as to be in contact with the metal foil 2. As shown in FIG. 6, this shape detection roller 4 is made up of a plurality of short cylindrical detection disks 5 having approximately the same diameter, stacked coaxially in the axial direction, and fastened through the plurality of tie rods 6. A sensor 7 is embedded in each detection disk unit 5 to detect the load at the portion that contacts the metal foil 2.

問題もある。(Problems to be Solved by the Invention) In the conventional shape detection roller 4 equipped with the coating layer 17, since the material of the coating layer 17 is resin-based, the roller surface is easily damaged, and it also depends on the rolling material. However, it is necessary to polish the roller surface frequently. In the case of stainless steel material, approximately 3
It must be polished at monthly intervals. There is also the problem that powder from the edges of the metal foil 2 gets stuck in the coating layer 17 and is transferred to the metal foil 2.

。However, the coating layer 17 is not made of a resin material, but is made of WC (
High roller surface hardness can be obtained by thermally spraying a hard material such as tungsten carbide onto the roller surface to form a highly hard surface layer. Therefore, the roller surface is not scratched by the rolling material and is free from polishing work, and furthermore, it is possible to prevent the powder of the metal foil 2 from getting into the coating layer 17.

あり、溶射が非常に困難であった。However, since the shape detection roller 4 has a structure in which a plurality of detection disks 5 are stacked, there are manufacturing problems such as chipping of the sprayed material when thermally spraying the hard material on each of the detection disks. It was extremely difficult.
また、板材を圧延する場合にも、上述の金属箔を圧延す
る場合と同様の問題点があった。Further, when rolling a plate material, there are problems similar to those when rolling the metal foil described above.
本発明は、かかる従来の課題に鑑み、外周面に硬質材料
