A one-piece window frame profile having on its circumference a plurality of grooves, recesses or the like for receiving additional profile strips, seal strips and the like, and trims. The profile consists of Duroplast material reinforced by fiber strands and has a roughly L-shaped cross section, a closed hollow being provided in the long arm of the L-shape and closed hollow in the cross arm of the L-shape. The grooves provided on the circumference have undercuts. In a process for producing the profile, a plurality of fiber strands are continuously impregnated with a Duroplast hardening resin, preferably polyester, said strand are combined into one bundle which is axially inserted in an elongated run-through mold, whose inside is shaped accordingly to the shape of the profile shape to be produced. The fiber strands are so conducted that they surround shafts inserted into the mold to form the hollows of the profile. Resin is hardened in the run-through mold. Windows and doors are produced by using the profile. |
