La présente invention concerne un procédé de contrôle de la qualité lors de la texturation d'un fil synthétique et un dispositif de texturation d'un fil synthétique. Le fil est tiré d'une bobine d'alimentation et est étiré et texturé dans une zone de texturation. Le fil est tiré de la zone de texturation à l'aide d'un rouleau d'alimentation entraîné. Un paramètre de qualité est détecté en continu pour effectuer le contrôle. Selon l'invention, pour pouvoir effectuer un contrôle de qualité sensible avec une faible dépense d'appareillage, on détecte comme paramètre de qualité un paramètre de fonctionnement physique d'un moteur électrique, de préférence un couple de fonctionnement du moteur électrique qui entraîne le rouleau d'alimentation pour tirer le fil. Pour cela, le dispositif de l'invention comporte un dispositif de contrôle qui est relié à une électronique de commande d'un moteur électrique. Le moyen de mesure est intégré dans l'électronique de commande et conçu de façon à pouvoir détecter un paramètre de fonctionnement du moteur électrique, de préférence un couple de fonctionnement, comme paramètre de qualité.
