<p>This invention relates to a roll which detects a push force at each part of a roll material located in a widthwise direction and detects the shape of the roll material by executing calculation processing. In a shape detecting roll of the type wherein a plurality of discs (2) each incorporating a pressure sensor (1) in its outer peripheral portion are disposed continuously and concentrically in the axial direction and gaps (11) for preventing mutual interference between the outer peripheral portions of adjacent discs (2) are defined between the side surfaces of the outer peripheral portions of the adjacent discs (2), the side surface of each disc outer peripheral portion which defines the gap (11) is activated by reverse electrolysis and then a corrosion-resistant plating is applied thereto. The plating film adheres strongly to the disc surface and the side surface of the outer peripheral portion of the disc will not corrode and can secure high detection accuracy for an extended period of time.</p> |
