The invention relates to a rotating nozzle structure of an extruder which comprises a rotatable nozzle, a die, which rests against the extruder frame and which comprises an annular front surface on the nozzle side, and a sealing plate, which is arranged between the front surface of the die and the nozzle and pressed tightly against the sealing surface of the nozzle to seal the nozzle with respect to the die. According to the invention, the die is arranged to slide in the axial direction with respect to the extruder frame and comprises a flow channel, which is under pressure of the material to be extruded and tapers conically towards the nozzle, and that the ratio of the area (A ) of the die's annular front surface to the area (A ) of the projection surface of the flow channel's conical section is between 0.1 and 10.

The invention relates to an arrangement in connection with a fibre coating line which comprises a fibre payout device ( ) from which fibres are arranged to be guided to a press ( ) for forming a coating round the fibres, a cooling device ( ) for cooling a conductor formed by the coating and the fibres, a pulling device ( ) by means of which the conductor formed by the coating and the fibres is pulled further from the press ( ), and means for guiding the conductor to the next processing stage after cooling, whereby the pulling device ( ) is arranged above the height of the line so as to enable the lowest point of the pulling device ( ) to be substantially at the height of the line. To facilitate the start-up of the line, the pulling device ( ) is arranged to be uplifted entirely above the height of the line substantially in a vertical direction.
