  • Apparatus for the contact-free continuous measurement and monitoring of magnetic tracks on moving film strips
    Patent number: 4346668
    Abstract: The invention relates to an apparatus and a method of contact-free, almost continuous measurement and monitoring of the width, thickness and position of magnetic tracks on moving film strips within wide limits of the speed. The track width and track position of the magnetic tracks are measured optically and the magnetically acting track cross section is measured electromagnetically via the track volume. The measured values are together recorded, evaluated and displayed and/or used for recontrolling the casting arrangement for emitting warning signals or for stopping the coating machine.
    Type: Grant
