Title (EN) METHOD AND ARRANGEMENT FOR COATING AN OPTIC CABLE
(FR) PROCEDE ET SYSTEME PERMETTANT DE REVETIR UN CABLE OPTIQUE
Abstract:
(EN) The invention relates to a method and an arrangement for coating an optic cable. The invention comprises means for leading optic fibres (2) to a press head (8) for providing a secondary coating around the fibres and means (7) for feeding grease used as filling into the secondary coating. To provide a fast process, the viscosity of the grease used as filling is lowered by means of an ultrasonic vibrator (9), before it is fed into the secondary coating.
(FR) L'invention concerne un procédé et un système qui permettent de revêtir un câble optique. Le système comprend un dispositif qui amène les fibres optiques (2) à une tête (8) de presse, de façon à appliquer un second revêtement autour des fibres, et un dispositif (7) qui amène de la graisse utilisée comme agent de remplissage dans le revêtement secondaire. Afin d'accélérer le procédé, un vibrateur à ultrasons (9) diminue la viscosité de la graisse utilisée comme remplissage avant son introduction dans le revêtement secondaire.
