ABSTRACT:
A process and apparatus for continuously measuring the tension of a filament being displaced from one point to another comprising applying a lateral pressure to the filament to displace it from its trajectory and measuring of variations of the counter-pressure exerted by the filament. The pressure is exerted laterally by producing between the filament and a support a flow of gas whose values of flow rate and pressure are such as to form a gas film between the filament and the support. The filament rides on this gas film. Measurement is made of the variations of one of the values of flow rate and pressure with respect to the corresponding value in the absence of the filament. A direct read-out of filament tension can be made.
