Abstract: To provide a method for the manufacture of rod-shaped components with one or more functional elements from a thermoplastic resin material, the length of the rod-shaped components being optionally variable, it is proposed that the method comprise the steps of producing in an extrusion process a blank having dimensions corresponding substantially to the rod-shaped component, and reshaping a portion of the blank to create a prescribed cross-sectional change by means of agglomeration of material in this portion, thereby to form the component with a functional element, the portion being heated prior to or during the reshaping to a reshaping temperature lying between the glass transition point and the melting point or softening point of the resin material.

Abstract: A composite section for frames of windows, doors, facade elements and the like consists of two metal section parts and at least one plastic insulating web which joins these metal section parts and is held with its ends in corresponding grooves of the metal section parts. The plastic material forming the insulating web is combined with a composite fiber skeleton consisting of heat-resistant fibers. The composite fiber skeleton is anchored in a positively and/or frictionally connected manner in the grooves of the metal section parts so as to also ensure cohesion of the metal section parts when the plastic material of the insulating web degenerates. The composite fiber skeleton is at least one band with thickened edge sections which are anchored in a positively connected manner in the grooves of the metal section parts.
