Determination of the thickness of a magnetic tape

To check the thickness of a magnetic tape in relation to preset tolerance limits in the course of the winding of the tape onto a hub of a tape cassette, the tape thickness is determined by means of a microprocessor from the number of revolutions of the hub during the winding of the tape and the woun...
