PURPOSE: To provide a shape detecting roll capable of surely preventing sticking of foreign substance under an adverse condition where much foreign substance is generated and apt to be firmly stuck. CONSTITUTION: A shaft 27 of a split roll 26 comprising a shape detecting roll 21 is fitted to a steel core 28. A plurality of load cells 30 are attached on the steel core 28, and a cylindrical sleeve 31 is fitted to the outside of the steel core 28. The load cells 30 are brought into contact with an inner circumferential part of the sleeve 31, ad a thermal spray coating layer 32 is formed on the outer circumferential part of the sleeve 31 by the spray forming. The surface of the thermal spray coating layer 32 is ground flat by a grinding wheel or a rotary abrasive grain belt. The chromium spray coating material is preferably used as a spray coating material to form the thermal spray coating layer 32. In particular, it is more preferable to use the chromium spray coating material mainly consisting of chromium carbide or chromium oxide. |
