PURPOSE:To form an in-line inspecting stage to detect the sticking defect of a magnetic tape, by winding a matter to be stuck and attached with a magnetic tape around a cylinder and then detecting optically the float-up at the tip of the matter to be stuck to discharge it. CONSTITUTION:A matter 11 to be stuck and attached with a magnetic tape 10 is carried on a line and pressed by a press-sticking roller 1. The matter 11 is then fed into a bent gap formed by a cylinder 2 having a certain curvature and a cover 3. In this case, the matter 11 shifts with close adhesion to the curvature of the cylinder 2 by rollers 1 and 5 and the cylinder 2. The curvature of the cylinder 2 is selected properly, and as a result, the magnetic tape which is adhered incompletely is forcibly torn off. Thus the tape 10 floats up toward the tangent line of the cylinder curvature in accordance with the degree of stiffness of the tape 10. The tip part 10a of the floated tape 10 is detected by a photoelectric tube 4. Therefore, if a magnetic tape having incomplete adhesion is detected, a defect signal is delivered. Then the defective tape is ejected by an ejector. |
