Abstract

La présente invention concerne un dispositif de traitement de fil électrique qui peut déterminer, avant un traitement de torsion, si un fil électrique est, ou non, un produit défectueux et annuler le traitement de torsion, et peut réaliser facilement un tri entre des fils électriques non défectueux et des fils électriques défectueux de telle sorte que la durée de vie du dispositif de torsion de fil électrique puisse être prolongée. Le dispositif de traitement de fil électrique comprend : une pince de transport avant (80F) et une pince de transport arrière (80R) se déplaçant vers une unité de pince de saisie avant (90F) et une unité de pince de saisie arrière (90R) tout en maintenant un premier fil électrique (C1) et un second fil électrique (C2) ; l'unité de pince de saisie avant (90F) et l'unité de pince de saisie arrière (90R) étant conçues de manière à effectuer une rotation par torsion ; et un capteur (106) destiné à détecter si les fils électriques (C1, C2) sont, ou non, présents, et qui est disposé sur un trajet de transport des fils électriques (C1, C2) allant du début de transport de la pince de transport avant (80F) et de la pince de transport arrière (80R) jusqu'à l'unité de pince de saisie avant (90F) et l'unité de pince de saisie arrière (90R).
