The present invention provides a method for the production of a fiber-reinforced plastics material profiled part. The method comprises the supplying of a tubular fiber braid in which a polymer matrix is arranged by being distributed therein. A longitudinal portion of the fiber braid is enclosed in a molding press. The molding press is heated to cure the polymer matrix in the longitudinal portion. After the press is opened, the fiber braid is drawn through the open press in order to position a further longitudinal portion of the fiber braid in the molding press. The further longitudinal portion is enclosed in the press. Another aspect of the invention is the provision of a device for the production of a fiber-reinforced plastics material profiled part.
