Abstract
A method and an arrangement in connection with a production line for optic cable, wherein optical fibers (1) are guided to a coating point (3), where filling gel is applied around the fibres, and a loose tubular casing is formed around the fibres and the filling gel. The fibres (1) are guided to the coating point through a device (4) that is formed from three parts (4a, 4b, 4c), said device being supported on a first base (5) and on a second base (6) moving in the travel direction of the fibres. Sensors (7, 8) are arranged in the first and second bases (5, 6) for measuring the force acting on the bases (5, 6). The arrangement further comprises means (9) for calculating the difference between said measured values for determining the friction force between the fibres and the tubular device (4).
