PCT No. PCT/FI96/00393 Sec. 371 Date Mar. 24, 1998 Sec. 102(e) Date Mar. 24, 1998 PCT Filed Jul. 30, 1996 PCT Pub. No. WO97/02503 PCT Pub. Date Jan. 23, 1997A method and arrangement for producing a basic element of a multi-element fibre optic cable having a coating tool (6) for forming a tubular sheathing around a single optical fibre (3) or a fibre bundle formed of several optical fibres (3), and a pulling device (8) placed after the coating tool (6) for pulling the sheathing and the fibres forward as a unit. In order to produce a stable product, the tension (t3) of the fibres (3) passed to the coating tool (6) is kept continuously at a controlled level. The direction of travel of the fibres and the sheathing is kept straight before and at the pulling device (8), and the pulling device (8) is spaced from the coating tool (6) at a distance depending on the production rate of the production line, so that desired sliding of the fibres (30 inside the sheathing is provided at the pulling device (8). |
