摘要：The invention relates to equipment for producing a flat fibre made from synthetic raw material and having predetermined characteristics by means of polymer extrusion. The extrusion line for producing a flat fibre made from synthetic raw material comprises a slot die for forming a film and a device for cooling said film, as well as devices for cutting the film into strips, stretching said strips and shrinking and winding the resultant fibres onto cores. The extrusion line comprises at least two extruders for shaping melts with different predetermined properties. The extrusion line comprises a device for distributing the melts across at least three layers of a multilayered film. The cooling device is in the form of a water-filled bath or chill rollers. Downstream of the cooling device, the line is provided with appliances for removing water from the film in the form of rollers with an elastic material about the periphery thereof, followed immediately by slotted pipes for the removal of the remaining moisture. The invention makes it possible to reduce the manufacturing cost of the product and the wear on the extrusion line.
