METHOD AND ARRANGEMENT IN CONNECTION WITH A FIBRE COATING LINE

摘要

The invention relates to a method and an arrangement in connection with a coating line, in which method a fibre, fibres or fibre bundles are unwound from payoff reels (1) and guided to a plastic extruder (3) by which a coating tube is formed around the fibre, the fibres or the fibre bundles. In the method and in the arrangement an assembly (4) formed by the coating tube and the fibre, the fibres or the fibre bundles is guided to and pulled trough a cooling through (5) to a main capstan (6) by using a clenching pull device (7) grasping to the outer surface of the coating tube. The clenching pull device (7) is placed inside the cooling trough whereby in order to eliminate post shrinkage of the coating tube the clenching pull device (7) is run at a faster speed than the main capstan (6). The clenching pull device (7) is a capstan comprising at least one pulley pair. The assembly (4) formed by the coating tube and the fibre, the fibres or the fibre bundles is guided between the pulleys of the pulley pair.
