  • Method and apparatus for inspecting an extruded tread
    Patent number: 6667799
    Abstract: A method and apparatus capable of inspecting the internal structure of an extruded tread efficiently and accurately on an on-line basis. Image data on the cut section of the extruded tread photographed by a CCD camera is processed by a tread internal structure inspection unit to calculate the brightnesses of rubber layers which differ in composition, the boundaries among the rubber layers on the cut section are located from differences among the calculated brightnesses of the rubber layers, and it is judged whether the internal structure of the photographed extruded tread is satisfactory or not by comparing the above boundaries with preset reference boundaries.
