Abstract

La présente invention concerne un procédé pour déterminer des paramètres de qualité d'un fil (9), fabriqué sur une station de travail (1) d'un métier à filer à rotor à fibres libérées et enroulé en bobine croisée (8). Selon ladite invention, ce procédé est caractérisé en ce qu'il consiste, d'abord, à insérer le fil (9) engagé sur la bobine croisée (8) dans un dispositif délivreur de fil (27), qui immobilise temporairement le fil (9), et à entraîner ensuite la bobine croisée (8) dans le sens de bobinage par l'intermédiaire de son moteur d'entraînement électrique (56) à une vitesse de contrôle prédéterminée, de façon à exercer une force de traction minimale prédéfinissable sur le fil (9). Ce procédé consiste également à enregistrer les caractéristiques électriques du moteur d'entraînement (56), telles que l'angle de rotation du rotor du moteur, la tension du moteur et/ou le courant du moteur, et à déterminer les paramètres de qualité du fil (9) à partir d'au moins une de ces caractéristiques électriques, compte tenu du titre de fil.
