Abstract

L'invention concerne un système de centrage pour un dispositif de dénudage (7) comprenant une tête de dénudage rotative (21) avec au moins un couteau de dénudage (3) pour un câble (2) qui peut être disposé le long d'un axe principal (1), en particulier un câble coaxial, un guide d'ondes optique, des fils isolés, ou similaires. Le système de centrage (5) présente deux mâchoires de centrage (4, 4') décalées de 180° l'une par rapport à l'autre à proximité immédiate du couteau de dénudage (3). Le couteau de dénudage (3) et les mâchoires de centrage (4, 4') sont disposés de manière à pouvoir être déplacés vers et depuis l'axe principal (1) sur celui-ci indépendamment les uns des autres, et le couteau de dénudage (3) et les mâchoires de centrage (4, 4') peuvent être entraînés par le biais d'un arbre d'entraînement ou d'un arbre creux (6, 60) dans la direction de fermeture ou d'ouverture de manière électromécanique ou par un moteur. Les mâchoires de centrage (4, 4') (qui, lorsqu'il y en a deux, se correspondent mutuellement) enserrent le câble (2) dans une position de fermeture (27) et le touchent sans force, ou bien les mâchoires de centrage (4, 4') se correspondant mutuellement maintiennent le câble (2) espacé de manière minimale avec un petit jeu des surfaces de centrage (29) des mâchoires de centrage (4, 4'). De ce fait, une rotation du câble à dénuder en même temps que les mâchoires est évitée. Le câble (2) reste ainsi selon l'invention dans la position de repos, tandis que les mâchoires de centrage (4, 4') tournent autour de l'axe principal (1) et du câble (2) pendant l'opération de dénudage.
