Abstract

See full text

The invention relates to a method and an arrangement in a coating line, in which a fibre (2) is uncoiled from a fibre start (1) by means of a pulling device (5) to an extrusion head (3) that comprises a die part (7) and a torpedo part, by means of which on the surface of a primary coated fibre there is arranged a buffer layer which is in tight contact with the primary coated fibre, and in which method the tightly coated fibre is cooled downstream of the extrusion head (3) in a predetermined manner. First there is determined a target value for line tension by means of the correlation between a line tension and a force required for stripping a buffer layer and the line tension between the extrusion head (3) and the pulling device (5) is measured. The obtained measurement data is compared with the target value to be obtained by means of the correlation between the line tension and the force required for stripping the buffer layer and the position of the die part (7) and/or the torpedo part of the extrusion head (3) is adjusted in the axial direction of the fibre such that the measurement value to be obtained from the line tension measurement attains the target value.
