FIELD: plastic profile production.
SUBSTANCE: invention is intended for the manufacture of fiber-reinforced plastic profiles in the form of long rods. Injection chamber (10) for pultrusion plant (12) contains case (18) with at least one fiber-supplying hole (18A) for supplying fibers (14), primarily glass fibers, carbon fibers or aramid fibers, injection nozzle (20) provided on case (18) for injecting liquid matrix material (22) and outlet (18B) for removing fibers (14) impregnated with matrix material (22) to curing device (24). Outlet (18B) is provided on a calibration nozzle connected to case (18). Fiber-supplying hole (18A) and outlet (18B) have an essentially circular cross-section. The diameter of fiber-supplying hole (18A) is larger than the diameter of outlet (18B).
EFFECT: technical result is providing the possibility of manufacturing rods of different diameters.
