    Abstract: There is disclosed an apparatus in which when a surface having a curved portion, for example, a tire surface is visually inspected, light is uniformly illuminated on the surface. In this apparatus, an image pickup operation is performed by a CCD for a region to be visually inspected, which is illuminated by turning on LEDs. Based on the image pickup result, a density distribution of the region to be visually inspected is prepared. A difference between a target light quantity and light quantity, which is obtained for each field angle of the density distribution at which the region to be visually inspected is illuminated by each light source unit, is calculated and corrected. This correction allows the quantity of light reflected from the region to be visually inspected on the inner peripheral surface to become uniform.

    Abstract: The present invention is a method and apparatus for centering a belt-shaped material. A conveying direction leading end portion and a conveying direction trailing end portion of triangular portions of the belt-shaped material are displaced in advance in directions opposite directions in which the conveying direction leading end portion and the conveying direction trailing end portion of the belt-shaped material are displaced when applied onto a forming drum. Centering of a constant-width portion of the belt-shaped material is carried out as follows. A width of the constant-width portion of the belt-shaped material is measured while the belt-shaped material is conveyed. In accordance with the measured width, a distance between a pair of guide portions which are disposed so as to be movable in a widthwise direction of the belt-shaped material is adjusted. The belt-shaped material is passed through a space between the adjusted guide portions.
