- the material for the reinforcing elements 1, 2, 4, 5, especially aluminum, steel or high-strength fiber composites are suitable. Since these materials are not with the thermoplastic base material of the plastic profile 10, 20, in PVC-hard window profiles, welded, the required shear-resistant connection is mainly to ensure a suitable form-fitting design of the contact surfaces. Possible embodiments are e.g.
- the stiffening is effected by a plug-in composite profile (See Figs. 22 to 25), in which the disadvantages are avoided from the point of view of the thermal insulation effect compared to a conventional U-reinforcing iron.

- Composite profile is represented by e.g. Milling the outer
- Foam layers largely adapted to the now larger main chamber of the plastic profile 10, so that hardly any cavities remain free. Since very low density foams have a better insulating effect than air filled ones
- the reinforcing elements 1, 2 consist of a material (metal, GRP) with a relatively high modulus of elasticity.
- the plastic profiles 10 are e.g. extruded in a so-called cross-spray nozzle, wherein the reinforcing elements 1, 2 are fed through the nozzle in the extrusion direction.
- Reinforcement elements 1, 2 are positively embedded in the plastic. That is, the edges must have longitudinally-operative retaining elements 3, e.g. Undercuts have, which are filled with plastic during extrusion in the nozzle. Undercuts in the transverse direction, in the plane of the reinforcing strip are provided so that the composite at long-term load due to force and

- Reinforcing element 1 (preferably made of metal) sawtooth structures are arranged as retaining elements 3 at both edges.
- Fig. 6 provided an enlarged view of
- sawtooth structure wherein the up and down bent saw teeth can be seen.
- the saw teeth are similar to the teeth of a hand saw and are also manufactured in such a way: punching out of gaps and cabinets of teeth, the teeth are alternately bent slightly to the left and right. This design causes a positive connection in two directions: in the longitudinal direction due to the tooth flanks and in the transverse direction as a result of the tooth pitch.
- Reinforcement element 1 is present with alternately slightly bent left and right segments.
- this structure for a holding element 3 also by means
- Wheels run exactly synchronously to each other and alternately have gaps and protrusions.

- Notches in the edges of the reinforcing element 1 generates. It does not depend on a specific assignment of the respective notches to each other or their exact geometry, so that the control of the various grinding wheels is also easy to do. In principle, such an edge structure as a holding element 3 is also at

- Anchoring against longitudinal displacement If these sections are mounted obliquely to the longitudinal axis (FIG. 19) or alternately obliquely backwards and obliquely backwards (FIG. 18), a very good connection against extension in the transverse direction results.
- the formation of the reinforcing elements 1, 2 was in the embodiments shown so far band-shaped or strip-shaped.
- Fig. 20 and 21 a plastic profile is shown, in which four wires 1, 2, 4, 5 as reinforcing elements in
- Plastic profile 10 are arranged.
- the wires 1, 2, 4, 5 may e.g. made of steel or aluminum.
- Plastic profile 10 are arranged. Here are the
- Reinforcement elements 1, 2, 4, 5 preferably arranged as far away from the neutral fiber.
- FIGS. 20 and 21 it can be seen that the arrangement of the wires as reinforcing elements 1, 2, 4, 5 takes place essentially in the corners of the plastic profile 10.
- a conventional window profile as shown in FIGS. 20 and 21, cause four wires of steel, each 3 mm
- the introduction into the plastic profile can e.g. done in two ways:
- the wire with the embossed surface has an excess in the tenths of a millimeter range with respect to the groove.
- the plastic profile 10 for windows shown in FIGS. 20 and 21 allows the reinforcements to be pressed into the finished plastic profile 10.
- the wires 1, 2, 4, 5 may be useful in profile extrusion, for example following cooling, even before the plastic profile 10 enters the caterpillar take-off, be pressed. However, they can also be pressed into the cut-to-length section bars or even into the frame sections cut to length and mitred for the purpose of making up the windows. It is expedient in this case, if the wire 1, 2, 4, 5 in addition to embossing the surface at about 120 to 200 ° C.
- the frame can therefore be stretched out immediately and the curing of the adhesive can then be done slowly over a longer period of time, which then has no negative impact on the cycle time.
- Respects e.g., shadow gap, burr formation,
- At least one further foam layer (cover layers) 33, 34 is additionally glued to the force-effective tension / compression reinforcing belts. If U-reinforcing bars are used, they are 1-2 mm smaller than the chambers in hollow sections, so they

- Two reinforcing layers 31, 32 which cause the desired bending stiffness in the two main directions.
- Appropriate materials are: steel with thicknesses of 0.5 to 2.0 mm, aluminum with thicknesses of 1.5 to 4 mm or fiberglass with thicknesses of 2.0 to 6.0 mm.
- cover layers 33, 34 are formed from foam and are selected with regard to the lowest possible thermal conductivity.
- Stiffening iron was inserted, and further chambers have formed.
- the composite profile as reinforcing element 1, 2 according to FIGS. 22 to 25 has five layers 30, 31, 32, 33, 34.
- plastic profiles 10 For the application of such 5-layer composite profiles, it is expedient to simplify the plastic profiles 10, that is to make more extrusion-friendly (see Fig. 24 and 25).
- These plastic profiles 10 have only three chambers, i. only two inner walls, which for stability and

- Reinforcement profiles in the PVC profile along small projecting noses can be sheared off comparatively easily and / or pressed. That is, that
- Reinforcing element 1 has a very close contact with the PVC profile and supports this immediately over a large area or at least linear. The screwing of the two
- Plastic profiles 10 can therefore be simplified, i. it suffice less screws with greater distances from each other.
- the thermal insulation effect increases when the
- Foam specification can be used. It is more appropriate to optimize the processes for the foam production on the one hand and for the profile extrusion separately on the other hand and to bring together the respective semi-finished products.
- the type of material can be chosen largely freely, e.g. Polystyrene or PE foam
- Foams made of PS or PE have lower or equal melting points than PVC at approx. 200 ° C, so that they also soften when warming up for corner welding and can additionally act as a welding surface.
- Profile bars which usually have a length of 6 m, the lengths required to form the window frame at 45 ° mitred. From each four frame profiles then a rectangular frame is welded. The joining surfaces are first heated to the welding temperature, about 200 ° C, and then pressed together. Depending on the profile joining surface, this results in a burnup of approx. 3mm. However, "erosion” is not to be understood literally, which means that the softened plastic material deforms plastically and forms a bead, which is subsequently removed again at the visible surfaces

- Plastic profiles 10 At this time, the position of the plastic profile 10 and the cut surface is known and defined exactly, so that by means of milling or grinding process, the required surface portions can be accurately edited. This can be done by a shank or end mill, which, for example, program-controlled moves off the required contours. Well suited is a high-speed
- Milling unit since only small forces are transmitted to the workpiece and thus flutter or vibration in the case of thin sheets is reduced.
- cutters come with a high speed milling
- Plastic profile 10 aligned, via a suitable, programmable path control are the required
- a sawing or cut-off grinding method can be used, wherein in the miter plane through slots are formed with about 2 mm depth, as shown in Fig. 30 and 31. That is, in the plane of
- Reinforcement elements 1, 2 (here as a reinforcing strip
- reinforcing elements 1, 2, 4, 5 can also be used for the corner joint.
- the metal components can transmit locally much larger forces than the plastic, the required
- Corner strength be ensured by the fact that only these metal components are connected to each other durable. This connection can be either by welding
- the metal bands or wires are not reset against the miter surface, but themselves interconnected. This bonding can be done either mechanically or by welding.
- Inserts By appropriate design of the inserts with “barbs and spring action” is a joining with moderate Effort possible. An opening then requires a very large amount of force. A support of the strength by gluing is of course also possible. Welding: similar to heat pulse welding
- the electrodes are applied to the externally accessible reinforcing elements 1, 2, 4, 5 (wires, bands, etc.) in the groove. If the miter surfaces are brought into contact, an electrically conductive connection is formed at the contact surface with great resistance - an arc arises at short notice, which leads to welding.
- the miter surfaces are joined so that the end faces of the metal reinforcement wires or tapes come into contact or form only a very narrow gap.
- the welding laser is guided in such a way that the metal melts and bonds in the joint surface.
