Abstract

Procédé pour déterminer des fluctuations successives des mesures transversales de fils textiles. La périodicité est déterminée par comparaison d'un signal de palpage F' émis lors du défilement avec une suite d'impulsions de réference Z' dont la période p est déterminée par des essais préliminaires. Application : détermination de l'effet de moiré dans des fils de rotor.
