Abstract A method of producing integral articles such as rudder parts etc. of plastics, reinforced with relatively long, continuous fibres is described. During the hot-setting or thermoforming process pressure is applied along at least two co-ordinate axes, with an angle between them of 30° to 90°. The method is characterised particularly in that to achieve the required pressures for each co-ordinate axis, from one of its co-ordinate directions a pressure element movable relative to the article is pressed against the article, while from the opposite co-ordinate axis at least one principally form stable bucker-up element in conjunction with said pressure element is caused to provide a pressure that acts on the article and against the direction of the force of the pressure element.
