The threefold nozzle is used to manufacture a hollow fibre membrane having durability, selective permeability and elasticity. The threefold nozzle comprises a nozzle body (a) having the upper plate (1), the central plate (2) and the supporting plate (3). The upper plate (1) includes an inlet (4) for introducing a cogulating agent. The central plate includes a nozzle (5) for passing the agent having a ring flange (5'), extruding hole (6) perforated through the plate (3), an inlet (8) for introducing a dope, a collecting room (7), having an outlet for the dope, an discharge path (10), and collecting room (11) of another dope for the outer membrane. The supporting plate (3) has hole (13) for extruding the dope for the outer membrane.
