<p>An automatic judging device and method for precisely judging the adequateness of the width, thickness, and stain of a continuously moving fiber aggregate. A fiber aggregate such as filter tow continuously moving on the front side of a background plate is imaged with a line sensor. Characteristic information including defect information on the thickness, width, and stain of the fiber aggregate is detected according to the generated video signal, and the defect information is extracted to judge the adequateness of the fiber aggregate. For example, the video signal is fed to a noise removing circuit (6a), and a defect signal concerning the thickness is extracted. On the basis of the extracted signal and a reference signal concerning the information, a judging circuit (7) judges the adequateness of the defect information. If the fiber aggregates is judged to be defective, an annunciating circuit (8) annunciates it. The video signal is clamped by a clamp circuit (5b), and defect information on the fiber aggregate may be extracted from the clamped video signal. The characteristic information or the defect information can be given to an external computer and used for process control.</p> |
