Abstract

Method and apparatus for continuously measuring the tension of a moving product e.g. yarn or sheet, wherein a moving product 2 is subjected to transverse vibrations between two fixed supports over a predetermined length of its path between set supports, and the vibrations are detected remotely by an optical system 6-9 including a laser 6. A signal representative of the detected vibrations is transmitted to an electronic servo system (Fig. 6) which controls the exciting system which may, for example, be a loudspeaker (1) or a ceramic finger to maintain resonance. The signal also is fed to a display system (16, 17) which indicates the tension, which may be deduced from the resonant frequency of the product or one of the harmonics thereof.
