FIELD: plastics processing. SUBSTANCE: preform is formed from continuous reinforcing fibres. The fibers are impregnated with a binding, profiled by pulling through a heated die and subjected to spiral winding of covering material. The winding of covering material is carried out by one or a plurality of oppositely directed monofilaments in front of the die entrance. After the die being passed through the monofilament is removed. EFFECT: manufacturing long length profiled articles provided with embossed surface. 1 dwg
