A nozzle for feeding a mixture of thermosetting plastic and hardener from a mixing chamber, to which feed lines for supply of thermosettable plastic as well as the hardener are connected. The mixing chamber communicates with at least two beam channels (14) having a diameter (b) of 0.5-1.5 mm, which converge in an angle ( alpha ) of 70-140 DEG towards a point outside the nozzle. By feeding a mixture of thermosetting plastic and hardener via the nozzle, the mixture has a viscosity of between 150 and 75.000 cpois, and that the mixture is extruded from the nozzle with a pressure of 75 to 100 bar.
