Description

2 AT 500 966 B1

The invention relates to a method for the production of extrudates, such as molded plastic dimensionally stable profiles, in particular window profiles, as described in the preamble of claim 1. In a production of dimensionally stable profiles, in particular window profiles, it is desirable in the production of the profiles at the same time protective layers and / or devices for sealing, damping and / or covering of profile parts or necessary for the sealing seal and or ., or form damping devices so that subsequent gluing and post-treatment of the profiles can be saved. It has already been attempted to produce such dimensionally stable hollow profiles with the protective layers or devices or sealing and / or damping devices consisting of elastically deformable plastics in a single pass by coextrusion. This takes place in that directly in the nozzle area after final shaping of the dimensionally stable profile via additional nozzle channels in the region of the die lip, which are connected to a further Extru-15 of a soft after cooling soft elastically deformable plastic, protective layers or devices or the seal - And or or damping device was extruded. However, the simultaneous extrusion of the protective layers or devices or sealing and / or or damping devices complicates the calibration of the dimensionally stable hollow profiles and therefore increases the cost of producing such, with protective layers or devices or sealing and / or or Damping devices provided, dimensionally stable hollow profiles.

Furthermore, it is already known - according to EP 0 159 307 A1 - aufzubrin on a tubular hollow profile, for example, a Kabeischutzrohr, an electrically conductive wire or a belt gene. This electrically conductive wire or the electrically conductive tape, however, in its own Work prepared to then be applied to the cable protection tube. For this purpose, it has also been proposed that this electrically conductive wire or the electrically conductive strip after cooling of the hollow profile or cable protection tube to a temperature of 50 ° C, ie in a dimensionally stable state in that region in which the wire or the Tape is to be attached to the cable protection tube circumference, is heated. At the same time, the wire to be applied or the band to be applied is heated by a heat source and pressed against the surface of the cable protection tube moved in the extrusion direction via an optionally heated pressing device. Following the application of the electrically conductive wire or tape, the entire profile is detected by the caterpillar 35, which causes the removal of the extruded cable protection tube. The connection between the electrically conductive wire or tape and the cable protection tube is made by a strong heating, for example by gas flames or infrared rays or the like., So it is in a high-pressure impressions by local melting of the thermoplastic material of the hollow profile or cable protection tube in this embeds and after cooling-40 in the pipe wall frits. Since in some cases the heat capacity of the wire is not sufficient to achieve an embedding or Einfrungung of the wire in the cable protection tube sufficiently to achieve, has already been provided, the hollow profile or the Kabeischutzrohr in that area in which the wire or the tape is to be incorporated, to heat. In addition, it is also possible to coat the pipe or the tape or the wire with a heat-reactive adhesive, so that in addition to the embedding and melting of the wire or tape, a bond between the hollow profile or the cable protection tube and the wire or Band happens.

Furthermore, it is known from EP 0 455 670 B1 or WO 90/08639 A1 to form dimensionally stable profiles from 50 extrudates. Such window profiles may be made by this method. In such window profiles, it is advantageous to provide additional devices for sealing, damping and covering. Since the requirements for such devices are different than the profiles or window profiles themselves, they can not be produced in a single operation. The procedure has therefore been such that the profile formed from the extrudate is calibrated after leaving and at least as far as it is cooled, it is sufficiently dimensionally stable. Before applying a protective layer or device, the surface was then heated in that area by applying the protective device, and at least placed in a doughy state. The protective layer or device was then extruded onto the heated area. Thus, an intimate connection between the protective layer or the device and the already cooled dimensionally stable profile in the manner of welding or partial crosslinking of the materials could be achieved.

A similar method is already known from EP 0 290 536 B1. This method and the associated system and the profiles produced therewith have proven themselves in practice, but the possibilities of the replaceable materials were limited in this method.

From DE 24 27 129 A1 discloses a coating device has become known, by means of which a film in the plastic state surface of a hollow profile, a film can be applied under pressure 15 without the risk of a change in shape of the profile. For this purpose, an extension extending through the extruded hollow profile is arranged following the tongue arranged in the mold channel. Following a softening zone, a mandrel having the same profile as the tongue is provided, in the region of which at least one coating roller for pressing the film to be applied and at least 20 for a support roller is arranged.

The present invention has for its object to provide a method and a system for producing a profile and a corresponding profile, which allows a high diversity in the replaceable protective layers and the devices, such as sealing-25 and damping devices. Preferably, the application of protective layers formed by film strips should also be possible. In addition, the life and durability and wear resistance of such profiles should be increased. In addition, preferably adapted to the particular application, optimized production should be possible. The object of the present invention is achieved by the features specified in the characterizing parts of claims 1, 33 and 49.

According to the method of the invention, it is advantageous that the longitudinal edges of the protective layer produced are surmounted by the devices, in particular the sealing and damping devices, i. that the device overlaps the protective layer and thus the strength and life is increased. At the same time, the delamination can be reduced and the production speed increased, since in the region of the longitudinal edges of the applied protective layer by the additionally applied device, the treatment time in positioning and pressing the protective layer can be reduced to the profile. 40

It is also advantageous according to claim 2, when the protective layer is formed by a film strip, as this completely different materials can be used with different manufacturing processes for amplification or optical design and to increase the physical or chemical resistance of the surface of the profiles. However, it is also conceivable for the protective layer to be produced and applied in an in-line process or to be extruded directly onto the profile by means of a further extruder and to be connected thereto.

Further advantages of the method will become apparent from the features of claims 3 to 32. 50

The task is, however, independently and independently of the manufacturing process also solved by the profile of claim 33. Because an edge region of the device overlaps a longitudinal edge of the protective layer, it is possible to arrange different protective layers in different regions of the surface of the profile without disadvantageous properties occurring in the transition region between the various layers and delaminate ions can. As a result, it is preferably possible to increase the strength properties of such profiles.

Further advantages of the profile can be found in claims 34 to 48. 5

But even with the system for producing profiles, the task is solved regardless of the procedure and the profile. The arrangement of the individual devices enables a continuous in-line production, regardless of whether the protective layer or the device is prefabricated or produced in an inline process. It is also possible only one of the two, namely the protective layer or the device to prefabricate and manufacture the other part inline. Thus, a high flexibility of the system and a rapid adaptation to different customer requirements and a reduction of storage is possible, as may sometimes be applied to prefabricated standard profiles differently required protective layers and devices. At the same time it is also possible to produce finished profiles with high performance continuously with different protective layers or devices optionally. Nevertheless, a high degree of flexibility for different variants is achieved by the rapid conversion of the system components.

Further advantages of the system according to the invention will become apparent from the claims 50 to 72. 20

For a better understanding of the invention, this will be explained in more detail below with reference to the embodiments illustrated in the drawings.

1 to 5 is a plant 1 for the manufacture of dimensionally stable profiles 2 of extruded plastic, in particular window profiles, which are usually designed as hollow profiles, Darge-45 represents.

For the production of extrudates, various base materials, such as plastics, but also fiber materials of natural materials, such as wood, leather, fibers, feathers or other materials or blended with natural materials plastics can be used verso. Of course, any fillers, such as chalk, fibers and the like can be arranged in the plastics.

This system comprises an extrusion device 3, a downstream nozzle 4 and a cooling and calibration device 5. The cooling and calibration device 5 is a Zufuhrvor-direction 101 for the supply and positioning of a protective layer 102 on the profile 2 after 5 AT 500 Ordered 966 B1.

Between a take-off device 6, which may be formed by a caterpillar take-off 7, and the feed device 101 is an application device 103 for an intermediate layer angeord-5 net. Both in the area of the application device 103, as well as in the region of the supply device 101, especially in the region of a pressure roller 104 for the protective layer 102, which also serves as a positioning roller for the protective layer 102, guide assemblies 105, 106 are arranged. The guide assemblies 105, 106 for height and lateral guidance as well as possibly also for the tilt-free guiding of the profile 2 and the io applicator 103 and the pressure roller 104 associated therewith can be positioned relative to one another and aligned with one another. Any desired mechanical, manual, semi-automatic or fully-automatic adjustable components, in particular roller arrangements, slide rails or the like, can be used for this purpose. In the direction of production - arrow 14 - the supply device 101 is followed by a further supply device 107 for applying a device 108, for sealing, damping or covering parts of the profile 2. This device 108 may be formed, for example, by sealing strips, sealing strips, sealing lips or even by damping elements, such as damping cords, bands, cylinders or the like, or by covers of recesses 20, in particular longitudinal grooves, recesses, openings or the like., Such profiles 2 ,

This further supply device 107 is downstream of the take-off device 6. 25 A side surface 8 of the profile 2 is associated with a heating device 9. The profile 2, which has exited from the cooling and calibration device 5 immediately before the application device 103, at this time has a temperature which is below e.g. is below 70 ° C. Thus, the profile 2 is cooled down so far that it is dimensionally stable and hardly any changes in the outer dimensions are to be expected. Thus, unilaterally acting on the profile pressure-30 forces or applied in tight areas heat energy can build up any unwanted stresses in the profile 2 or deform the profile subsequently undesirable.

The supply device 101 for the protective layer 102 as well as the applicator device 103 for the intermediate layer, which may be upstream therefrom, is shown in greater detail in the present exemplary embodiment, 35 according to FIGS. 3 and 4. The feeding device 101 comprises the guide arrangement 106, which is arranged on a machine frame 109 and for which the profile 2 is guided precisely and in terms of lateral and height as well as without jamming.

For positioned guiding and positionally accurate adjustment of the film strip formed, for example, by a plastic tape (composite material) or other materials, the pressure roller 104 or the positioning roller is relative to the guide elements of the guide arrangement 106 of the height formed by rollers 110, for example Side adjustable by means of a drive 111. Thus, the pressure rollers 104 and the positioning rollers and the rollers 110 of the guide assembly 106 are adjustable relative to each other. 45

The pressure roller 104 is further associated with a side straightening device 112 for the protective layer 102, in particular a foil strip 113. The side-facing device 112 has a pivot plate 114. The pivot plate 114 is pivotable about a pivot axis 115, which is aligned approximately parallel to the production direction - arrow 14 - to eliminate Seitenabwei-50 chutions in the development of the film strip 113. By pivoting the pivot plate 114, the foil strip 113 can be adjusted in the longitudinal direction of the axis of rotation of the pressure roller 104 or the positioning roller and adapted to the longitudinal profile of the profile 2. In addition, it is possible to adjust the pressure roller 104 or the positioning roller via an additional axis 116 aligned transversely to the profile production direction-arrow 14-in order to ensure exact positioning of the pressure roller 104 or the positioning roller also transversely to the profile longitudinal direction to enable. For guiding and facilitated lateral movement transversely to the longitudinal direction of the profile 2 or to its production direction, a deflection roller 117 is arranged both in the end region of the swivel plate 114 facing the profile 2 and in the further end region opposite thereto. The pressure roller 104 or the positioning roller is further preceded by an adhesive application device 118. In the present embodiment, the adhesive applicator 118 is disposed between a reel 119 for receiving the foil strip 113 and the pivot plate 114. This is because a heating device 120 is arranged in the region of the swivel plate 114 or the side-straightening device 112. For checking and exact feeding of the film strip 113, a unwinding device 121 is provided for the reel 119, which device cooperates with a belt loop control device 122 and is provided for applying an intermediate layer, which will be explained in more detail with reference to the following figures. This intermediate layer may be formed by, for example, a primer, residual wax or the like resulting from the extrusion of the profile 2, as well as a corresponding reagent or adhesive or adhesion improving agent. An application of this intermediate layer can take place, for example, in those areas in which the protective layer 102 or the film strip 113 is applied to the profile 2, by spraying, rolling or stripping. The corresponding devices for semi-automatic or fully automatic applications of this intermediate layer are familiar to the person skilled in the art and devices known from the prior art can be used for this purpose. The corresponding elements or device parts for applying the intermediate layer can be adjusted by means of adjusting devices 123 relative to the guide arrangement 105, 106 or its rollers, slide rails, guide elements or the like for the profile 2. Because the guide elements of the guide arrangement 105 are manually, semi-automatically or fully automatically adjustable in different space directions, a relative adjustability between the elements for applying the intermediate layer and the guide elements of the guide arrangement 105 is possible, so that a perfect adaptation and a secure order of Intermediate layer can be achieved in desired areas of the profile 2. 35

In addition, it is possible for the applicator elements 124 of the applicator device 103 to arrange one device 125 or more devices for heating or heating.

By heating or heating the applied intermediate layer, the effect 40 of these applied chemicals, for example the dissolution of the surface to increase the surface roughness for achieving an improved connection or activating a powdery applied active substance, can be initiated and, moreover, can be achieved by heating or cooling Heating of the surface of the profile 2, an improved connection and adhesion between the surface of the profile and the foil strip 113 or the protective layer 102 are achieved.

As can be better seen in connection with the further FIGS. 5 to 8, the further supply device 107, the heater 9 - Fig. 5 - upstream, which may be formed by a hot air blower 10, with which a surface layer 11 with a width 12, the eg is smaller than a total width 13 of the profile 2 as far as can be heated or heated, e.g. can also be in doughy or plasticized state. This surface layer 11 may conveniently be heated to a temperature between 50 ° C and 130 ° C, preferably at 80 ° C to 110 ° C, heated. Preferably, the modulus of elasticity of the plastic is e.g. when the device 108 is formed by elastic or deformable sealing and / or damping devices 19, smaller than the corresponding elasticity modulus of the profile 2. Due to the higher elasticity of the sealing and / or damping device, a sealed conclusion between abutting hard profile parts and the soft sealing and / or damping devices 5 19 done and it is also ensured that in this deformation of the log processing and / or damping device 19, the profile 2 remains stable and is not also deformed. As a material for such sealing and / or damping devices are mainly polyether foams, open or closed-cell soft PU foams and mixed materials of plastic and rubber in question. 10

The heating device 9 is downstream of another nozzle 15 in the production direction - arrow 14 - which comes to rest on the side surface 8 of the profile 2. This nozzle 15 is coupled to an outlet 16 of a further extrusion device 17 and has a nozzle gap 18, which in the present example corresponds in its cross section to a cross section of the sealing and / or damping device 19 forming the device 108. This sealing and / or damping device 19 is formed in the present embodiment by an elastically deformable sealing strip 20. It is formed, for example, from a plastic, which is elastically deformable even after cooling, with a low modulus of elasticity, which is preferably elastically deformable and deformable by a corresponding compressive force and thus can effect a tight seal between abutting profiles.

Of course, the device 108 may also be formed by inserting other components, such as cover strips for recesses present in the profile 2, for example receiving grooves for additional sealing profiles or the like, or as a damping stop bar or as a durable contact surface.

Depending on the desired application and application, the device 108 may therefore consist of a variety of materials. Especially when it should be closed with existing groove or longitudinal openings, which must be opened at a later time, it is advantageous if between the device 108 and the adjacent wall surfaces of the profile 2 corresponding weakening areas are formed.

However, it is also possible in such cases to use a very hard and very brittle material with a small wall thickness, so that the device 108 can be simply broken out if necessary.

The materials used can also be plastics with highly elastic properties.

However, very brittle materials or with certain fillers, such as chalk, fibers 40 and the like, filled materials made of plastic or rubber or mixtures thereof may also be used and used.

In the present case, the device 108 is now formed in the course of a continuous production of the profile 2 from the raw material and therefore the extrusion device 17 is provided. 45 From the plastic raw material, a melt is processed, which is pressed out through the nozzle gap 18 and the device 108, for example, a sealing device in a längsveriaufende groove of the profile 2, which is provided with a projecting beyond the groove sealing lip form. Thus, as can be seen from the representation in FIG. 5, a nozzle body 21 of the nozzle 15 is pressed against the side face 8 of the profile 2 by means of a pressing drive 22.

The profile 2 can not escape even with the outgoing by the contact pressure 22 of an incoming or press-in 126 force, since the profile 2, for example, in a 55 caliber 23 of a guide assembly 127 exactly the height and the side is guided. Of course, this caliber 23 can also have an equivalent roller arrangement and, of course, more than one caliber can be provided. Thus, it is also possible to feed or support the profile 2 by a caliber 24 before entering the downstream extraction device 6. This guidance and support in the calibers 23 and 24 takes place both the 5 side and the height. In addition, the profile 2 is held by the pulling force exerted with the puller 6 and the caliber 23 in one of the extrusion device 17 nachgeord-Neten cooling and calibration 128 under a strong tensile stress, so that it hardly for this reason contrary to the Anpressantrieb 22 can dodge applied pressure force. 10

Furthermore, the individual chain links 25 may have recesses 26 which in their cross-section substantially correspond to the cross-section of the sealing strip 20 of the sealing and / or damping device 19. This prevents that immediately after the shaping of the sealing and / or damping device 19, this is destroyed by the contact pressure of the take-off device 6 or the caterpillars 7 or deformed undesirable.

As further shown in Fig. 5, the heating device 9 may also be formed by a heating rod 27, for example an infrared heating rod, which is heated by gas or, for example, by current accordingly, to a sufficient heat energy, which is schematically indicated by 20 arrows 28, applied to the surface layer 11, so that it can be brought to a temperature between 50 ° C and 130 ° C and 60 ° C to 180 ° C at which the plastic material melts.

For monitoring the temperature profile, in particular the temperature of the profile 2 25 and / or the protective layer 102 before entering the heating device 9, it is possible to use a sensor 29, for example in the region of the caliber 23, e.g. the cooling and calibration 128 provided. Similarly, between the heating device 9 and the nozzle 15, a sensor 30 can be arranged, with which the temperature in the region of the surface layer 11 can be determined. The transducers 29 and 30 may be connected to a control device 31, which is connected via supply and control lines 32 with the heating device 9 on the one hand and with a line 33 to a power supply system, for example a power grid and possibly a gas network.

The regulation of the delivery of the heat energy indicated by arrows 28 to the surface layer 11 can now take place as a function of the measured value of the sensor 30, namely the temperature in the region of the surface layer 11 of the profile 2 or the protective layer 102. But it is also possible to include in the control process, the measured values of the sensor 29 so that they can be fully automatically taken into account in temperature variations of the incoming into the heater 9 profile 2, so that 40 fluctuations in the temperature in the surface layer 11 in the nozzle 15 are largely avoided can and the measured values of the transmitter 30 only represent a safety monitoring.

Furthermore, it is advantageous if the side surface 8 of the profile 2 is heated only in the region of the surface 45 layer 11 with a width 12 to which the device 108 is applied to the profile 2 and the longitudinal edges of the protective layer 102, since therewith a adversely affecting the surface quality in the device 108 of the profile 2 and the protective layer 102 adjacent areas is turned off. However, if it is desired or not disturbing for the quality of the profile 2 or the protective layer 102, then the entire side surface can also be heated accordingly.

The method according to the invention and the profiles 2 which can be produced with this method and the corresponding system will now be explained with reference to some embodiments of possible profiles in FIGS. 6 to 8. At the same time, the formation of fiction, 55 corresponding profiles will be explained. FIGS. 6 and 7 show an embodiment of a profile 2 which can be produced according to the method according to the invention and with a system according to the invention. As can be seen from this drawing, it is a hollow profile 34, for example, for a window, which is provided with a plurality of chambers 35. In addition, in the area of the surfaces different projections 129 and locking strips 5 130 hen vorgese for snapping together with other profiles or for better connection.

The profile 2 consists of a dimensionally stable extrudate, for example a plasticized, re-hardened plastic, a mixture of plastic, rubber and / or other Füllstof-io fen or other materials. On this profile 2 of dimensionally stable extrudate is a protective layer 102 in the present case for covering a plurality, in the previous case angularly extending to each other, planar wall portions 131,132, 133, 134,135 arranged.

These planar wall parts 131 to 135, as shown in FIG. 6, are arranged on the surface 15 of the profile 2. Longitudinal edges 136, 137, in the present case so the protective layer 102 in the longitudinal direction of the profile 2 laterally delimiting side surfaces of the example formed by a film strip 113 protective layer 102nd

The protective layer 102 now projects beyond the planar wall part 132 with the longitudinal edge 136 20 over the edge between the planar wall parts 131, 132 and into the flat wall part 131. This planar wall portion, for example, is not facing the sun, and is covered only in part with a longitudinal strip 138 of the protective layer 102, which may be between 0.2 to 15 mm, preferably between 0.2 and 5 mm. The opposite longitudinal edge 137 of the protective layer 102 projects beyond a side edge 139 of a groove-shaped depression 140 and is connected to a side wall 141 of the groove-shaped depression 140. Thus, a longitudinal strip 142 with a width 143 which is between 0.2 and 15 mm, preferably 0.1 to 8 mm, projects into the groove-shaped recess 140. It is of course also any other width extension, depending on the thickness of the protection " 30 layer 102 and the strength and the depth of the groove-shaped recess 140 possible.

In the present exemplary embodiment, the protective layer 102 can be extruded over the whole area on the planar wall parts 131 to 135 or a part of the side wall 141. But it is also possible to make the connection between the device 102 and the profile 2 by an adhesive layer. Other connection options, such as ultrasonic welding or the like., Are conceivable. The bonding or the extrusion of the protective layer 102 can be done directly on the surface of the profile 2 immediately after exiting the calibration device 5, so after calibration, but it is also 40 possible to apply a primer before applying a protective layer, the an adhesion improvement of the adhesive or the extruded material allows. In the present case, it is symbolically indicated by small depressions 144 that the planar wall parts 131 to 135 and the side wall 141 are pretreated with a primer which opens the pores of the surface and thus produces a higher surface roughness, which has an improved adhesion of the protective layer 102 the surface of the profile 102 allows. It is of course also within the skill of the art possible to apply other precursors or layers or agents to the surface of the profile and, for example, remove the wax residue from the extrusion or other lubricant residues to allow for better adhesion of the protective layer 102. Furthermore, it is of course also possible to soften by the devices 125 for heating the surface of the profile 2 or transfer into a doughy or viscous state, so that it is especially when extruding the device 108 to an intimate adhesion or to a chemical and physical bonding of the molecules between the protective layer 102 and the profile 2. If, on the other hand, a prefabricated film strip is used to seal it onto the surface or the wall parts 131 to 135, this has the advantage that a very wide range of physical properties is achieved

Properties of plastics used and above all a rapid change of type or design change to different requirements or customer requirements is possible at any time, since the system does not have to be shut down, but the different films colors or materials by Aneinanderhängen the different film strips immediately aneinan-5 follows can be applied to the same profile 2.

As can further be seen from FIG. 6, after the protective layer 102 has been applied, a device 108 -shown in dotted lines-for example, a sealing strip 145 made of elastic plastic can be fixed in the profile 2 into the groove-shaped depression 140. 10

The fixation can be effected in that a corresponding sealing strip 145 or a sealing and / or damping device 19 is produced and calibrated in the course of ongoing production via its own extruder, supplied cooled and rolled into the groove-shaped recess 140. 15

In this case, it is possible to heat, melt or glue the adhesion between the profile 2, the longitudinal strip 142 or the longitudinal edge 137 in order to allow a better adhesion of the device 108. But it is also possible to subsequently produce the compounds via UV welding or other connection methods. If the sealing strip 145, the flexible sealing strip or sealing bead is produced inline and cooled beforehand, it is also possible to hold the sealing strip in the groove-shaped recess only via an interference fit via corresponding compression thereof.

On the other hand, it is also possible to use externally prefabricated device 108. 25

Furthermore, it is also possible to produce the device 108 in such a way that the wall part 135 is correspondingly heated up to the boundary line or side wall 141 or is heated up to such an extent by the heating device 9 that it changes into a doughy or viscous state. Thereafter, with the heater 9, these areas can be heated to the extent that 30 " For example, the surface layer 11 melts.

This now causes the device 108, which is positioned exactly on the course of the wall parts 131 to 135, and extends with its longitudinal strip 142 in the groove-shaped recess 140 and in the region of the longitudinal edge 137 and the longitudinal strip 142 of the device 108 in the 35th Direction to the opposite longitudinal edge 136 of the protective layer 102 is surmounted.

In the present embodiment, the longitudinal edge 137 and the longitudinal strip 142 are not only surmounted but embedded by the device 108 or the introduced plastic of the sealing strip 145. Thus, the longitudinal edge 137 is additionally fixed in position relative to the profile 2 and 40 achieved a longer life and a higher peel strength of the protective layer 102 of the profile 2. Above all, this reliably prevents the detachment of the longitudinal edge and premature delamination even under extreme temperature conditions. 45 In the opposite edge region, which is associated with the longitudinal edge 136, is further shown that even if no groove-shaped depression is present, for example, after the application of the protective layer 102, a device 108 - also shown by dashed lines - can be formed, for example, by a plastic strip which may be formed as a locking strip 130, molded or can be attached to the profile 2. Thus, it is possible that the longitudinal edge 136 can be formed by the subsequently applied device 108 to form a locking element 146 for snapping a further profile 2 and can. Thus, the strength, the life and resilience of the profile 2 in the region of the other longitudinal edge 136 of the protective layer 102 can be increased. In FIG. 7, the same profile is shown, in which case an intermediate layer 147 is applied to the wall parts 131 to 135 for the time being when the protective layer 102 11 AT 500 966 B1 is applied. This intermediate layer can be, for example, an adhesive, but also an adhesion-promoting layer, and this layer can also be multi-layered if necessary. In this embodiment, it is again shown that both the protective layer 102 and the intermediate layer 147 are attacked by the introduction of the device 108, for example a sealing strip 145 and / or a sealing and / or damping device 19.

Before the application of the intermediate layer 147 or even afterwards, the partial region or wall part 131 to 135 can be heated to a temperature between 25 ° C and 70 ° C, preferably 30 ° C to 50 ° C. But it is also possible to heat the partial area or the wall portion 131 to 135 after the application of the protective layer 102 to a temperature between 50 ° C and 140 eC, preferably 80 ° C to 110 ° C, and to put it into a doughy state, In order to achieve the same effects as they have already been explained in detail 15 and the laying of the protective layer 102, the intermediate layer 147 is dried.

The drying can be done for example with hot air.

It is also advantageous that the longitudinal edges 136, 137, the protective layer 102 or the film strip 20 113 can protrude into a receiving or holding region of the device 108, that is to say, for example, a groove-shaped depression. The device 108 can be inserted or snapped into a longitudinal depression of the profile 2 or into the groove-shaped depression 140.

The intensive connection and mounting of the protective layer 102 or the securing of the layer 25 whose longitudinal edges 136, 137 is achieved mainly by the device 108 on the longitudinal strips 138, 142 of the protective layer 102 and the foil strip 113 and on this immediate Longitudinal area is extruded. This ensures an intimate connection and fixation. Due to the fact that the device 108 projects beyond a part of the protective layer 102, the device 108 is intensively connected not only to the longitudinal strips 138, 142 of the protective layer 102, but also to the longitudinal regions of the profile 2 immediately adjacent the longitudinal edges 136, 137. As a result, these areas, in which the device 108 comes to rest, are likewise to be heated, if appropriate to be treated with a primer, or heated to such an extent that they change into a doughy or glassy state.

As the temperature is recommended in this case a heating to a temperature between 30 ° C and 80 ° C, preferably 50 ° C to 70 eC. Of course, the longitudinal edges or longitudinal regions can also be heated at a temperature between 80 ° C and 150 ° C, preferably between 100 ° C and 120 ° C, in order to achieve an even more intimate connection.

If the device 108 is produced inline, ie in the course of the ongoing production and the ongoing application of the protective layer 102, it is recommended that the device 108, which is formed by an elastically restoring or sealing and / or damping device 19, after the extrusion for calibration and cooling.

FIG. 8 shows another embodiment variant of the profile 2 according to the invention or the structure so and the arrangement of the protective layer 102 or of the devices 108.

As an example, here the profile is shown again as a multi-chamber profile with a plurality of chambers 35. 55 on planar surface wall portions 131, 132, 133, 134 and 135, in turn, the protective layer 102 12 AT 500 966 B1 glued or welded.

The longitudinal edge 136, 137 of the protective layer 102 is arranged sunk in this case in a recess 148 of the planar wall portion 135. In this case, the device 108 once again embeds the longitudinal edge and the longitudinal strips 142 of the protective layer 102 and at the same time forms a planar wall part 149 which closes off a groove-shaped depression 140 toward the outside.

In order to be able to subsequently remove this wall part 149 in order, for example, to use a sealing device, weakening regions or lines of weakness 150 are arranged in the end regions facing the profile 2. Thus, at any time, the wall part 149 can be easily broken out.

In the region of the opposite longitudinal edge 136, for example, a device 108 formed by a sealing and / or damping device 19 is shown, which is designed as a sealing lip. This is partly inserted into a groove-shaped depression and at the same time projects beyond the longitudinal edge 136 and the longitudinal strip 138 of the protective layer 102.

For this purpose, this surface layer 11 is heated to a temperature of over 90 ° C, preferably between 150 ° C and 180 ° C, heated. The exact temperature at which this plastic is to be heated, not only depends on the different plastic materials used, but also by the additives contained in these plastic materials, so that an exact process temperature in advance can not be specified. It is essential, however, that the plastic material in the region of this surface layer is heated to such an extent that it melts in the manner of a welding operation with the plastic applied directly to the heating device 9 by means of the nozzle 15 for producing the device or the sealing strip 145 or the sealing and / or damping device 19 connect, in particular can weld. 30 The base material of the Profiles 2 is always made of a material that remains hard and dimensionally stable after final cooling in the desired application range at temperatures of approx. -30 ° C to +80 ° C. The base material for the protective layers 102, which may be formed of plastic layers, consists of a material corresponding to the base material of the profile 2 or similar polyvinyl chloride (PVC) or a higher quality polyvinyl chloride. The materials used for this can also have a higher resistance to UV radiation, but it is also possible to use acrylic or any other type of thermoplastic as the material.

These protective layers 102 have a modulus of elasticity which substantially corresponds to the modulus of elasticity of the profile 2. These layers are therefore hard layers which are also resistant to deformation.

Of course, it is also possible for those plastic layers or covering devices and protective layers for closing the depressions to have a lower modulus of elasticity than the base material of the profile 2. In any case, however, this material will preferably have a modulus of elasticity. the still no plastic or elastic deformation allowed in the use of such profiles 2 temperature range. However, it is also possible for those protective layers or covering devices, with which depressions are closed, to equip them with a modulus of elasticity which is considerably higher than that of the profile 2, so that these protective layers, which close the depressions, are simply cut out with a knife can be, if in these wells, another component, such as a seal or a stop bar or a far-55 rer profile part to be used. 13 AT 500 966 B1
