A window frame profile which is integrally formed and provided on its peripheral face with a plurality of grooves, recesses and the like in which additional profile strips, sealing strips and the like and fittings can be fastened. The profile consists of a duroplastic material reinforced by means of fiber strands and has an approximately L-shaped cross section, with a closed hollow space provided in the longitudinal leg of the L-shape and a closed hollow space provided in the transverse leg of the L-shape.The grooves on the peripheral face are provided with undercuts. For the production of the profile, a process is provided in which a plurality of fiber strands is continuously impregnated with a pressure setting synthetic resin, preferably polyester, and united into a bundle which is axially introduced into an elongated, hollow passage mold whose inner space is shaped in conformity with the form of the profile to be produced. The fiber strands are made to pass in such a way that they encircle mandrels which are inserted into the hollow passage mold in order to form the hollow spaces of the profile. The synthetic resin is cured inside of the hollow passage mold. Windows and doors are formed under use of the profile. |
