Zusammenfassung: | PROBLEM TO BE SOLVED: To always accurately and automatically detect defecting coating on the surface of a hose. SOLUTION: The image of a hose 1 having an adhesive layer 1b formed on its surface by an adhesive extruder 5 is continuously inputted to an image input part 2 to be subjected to binarizing processing by an image processing part 3. At this time, the adhesive layer 1b is processed as black image data and the part other than the adhesive layer 1b is processed as white image data. When the coating inferiority of an adhesive is generated, the area of the white image data is increased by a coating inferiority part and, when the white image data exceeds a reference value, this data is detected as coating inferiority. |
