Characteristic of the known technical solutions:

Be a known from DE-AS 2 90-4 192 * method of this type, the metal profile after filling the upper channel with a casting resin and after its setting initially twisted about its longitudinal axis, then that of the first filled through the channel In a subsequent process step, a tool is inserted into the cavity bounded by the metal bridging webs and the two bridging webs are removed.

It has been found that this known method is applicable only for a limited number of different composite profile cross-sectional shapes. For example, difficulties in the production of composite profiles, in which the Hohlrauraquerschnitt falls below a certain free size, so that is not available in all cases enough space for insertion and handling of the tool for removing the Oberbööckungsstege available.

In addition, for the practice of the known method special devices are necessary, the 'use insoluble is limited, such as with such systems, for example, very small profile cross sections, which have only a metal Oberbrückungssteg, or profile cross sections with more than two stacked Isolierkernleisten can not be produced ,

From the applicant's DE-AS 2 721 367 a method for the production of composite profiles is known, in which only a metal Oberbrückungssteg is provided, which forms the lower bottom cover of an upwardly open-sided cavity, wherein in a first process step

236 88 0 2

the bottom gutter is susgefällt before it can be started to successively compensate for the upper grooves for the purpose of producing the further arranged over Isolierkernleisten. The fact that the metal profiles are not to be relocated during their entire manufacturing process from their basic position, a transfer of this known process sequence on the production of composite profiles with multiple metal cavities limiting Oberbrückungsstegen is not possible.

aim the Invention:

By the invention, the disadvantages are eliminated and an economical and cost-effective production of composite profiles allows.

Explanation of the essence of the invention:

The invention has for its object to develop an improved method and apparatus of the type mentioned, with both composite profiles small Ouerschnittsabmessungen and large profile sections can be made, regardless of whether they have one or more metal Oberbrückungsstege.

Erfind according to the object is achieved in that after filling the first groove and hardening des- plastic first or the metal Oberbrückungsstege be separated and that after turning the metal profiles and before filling the other channel (s) above the first formed Isolierkernleiste (n) between the metal profiles a the bottom of the other (s) channel (s) forming, formed as a separate part bar is made of poor thermal conductivity material.

By erfindungsgeraäßen process flow, it is possible to produce composite profiles of both small and large cross-sections in a continuous workflow. The fact that already in a stage prior to turning the metal profiles, the metal connection between the profiles is repealed, it does not matter if the Ausgangssprofilquerschnitte one or more metal Oberbrückungsstege have, so that it does not on the Ouerschnittsgröße the Isolierkernleisten limiting in height cavity can arrive more. In addition, the conditions have been created by the process sequence according to the invention that existing manufacturing plants can now be used universally by minor structural conversions. Instead of the tools used in the known method, which must be introduced into the cavity of the composite profiles in order to remove the Oberbrückungsstege can rely on existing saws or cutters, which are available anyway in the manufacturing facility.

According to an inventive further development of the method is useful after filling first poured gutter and before separating the or the Oberbrückungssteges and turning the metal profiles at a distance above the first formed Isolierkernleiste between the metal profiles at least one of the 3oden an additional groove forming bar from bad heat conducting Material introduced and filled this channel with plastic. As a result, the production of special profile shapes with more than two superposed Isolierkernleisten is possible. To further stabilize the output profile cross-sections during their production, it is proposed that the channels to be filled with plastic before turning the metal profiles be opened by removing a metal bridging web,

236880 2

In the production of composite profiles with more than two juxtaposed metal profiles is preferably carried out the separation of the metal Oberbrückungsstege for all insulation simultaneously. As an alternative, however, this can also take place one after the other in order to achieve a better distribution of forces during this machining process. It is also expedient to introduce the separate floor strips to form further channels arranged next to each other and to fill the channels with plastic at the same time.

In a composite profile with more than two stacked Isolierkernleisten can according to the invention after the turning of the composite profile one of the number of Ipslierkernleisten corresponding number of channels successively filled with casting material. According to a particular feature of a composite profile with several superimposed metal Oberbrückungsstegen the removal of the same takes place in one and the same operation.

In cases where it require the 'space, the composite profile is advantageously transferred after turning into a second transport path and transported in said second transport path in countertransference the conveying direction in the first transport path the opposite direction. Preferably, the turning and the passing of the composite profiles to the second transport path takes place simultaneously.

The apparatus for carrying out the method, which is based in its basic construction on the device known from the Applicant's DE-PS 2 913234 and the a support supporting the metal profiles and transport and guide means for the Me-tsllpro * i3? E for passing them under a first casting device and at least one of these downstream in the transport direction

further casting device and a device arranged between two successive pouring devices for introducing a separating strip between the metal profiles and a device for removing one or more metal Oberbrückungsstege owns, is characterized daf3 in the transport direction behind the first casting device and in front of the device for introducing the separator strip the device for removing the or the Oberbrückungssteges provided and is arranged at a distance behind this one station for turning the composite profile about its longitudinal axis. Such a configured device can be achieved with the simplest means by retooling a system available on the market, so that universal use is possible with one and the same device. The inventively designed device allows the economic production of Ver. bund both profiles with one as well as several metal Oberbrückungsstegan in a continuous work flow, wherein the changeover from one to the other composite profile Ouerschnittsform only dia connection or disconnection of individual units is necessary.

Preferably, in the transport direction behind the first casting device and before the device for removing the or the Oberbrückungsstege (s), a further device for introducing the separator strip and a casting device is arranged. This makes it possible to produce large profile cross sections with a basic structure which is preferred in practice. Preferably, the transport path in the region of the turning station runs in a second, parallel to the first transport path. The end of the transport path is over and the conveying direction of the second transport path is switched in the opposite direction to the conveying direction of the first transport path. This embodiment is selected when the production line should be as short as possible. Purpose-

Advantageously, the turning station consists of a rotating device .für the composite profile and is the upper feed station of a composite profile from the first transport path by parallel displacement on the downstream transport path conveying conveyor belt, a transport roller conveyor, or the like. educated.

In a further embodiment of the invention, the device for introducing the separating strips is designed as a separating strip supply roll, which is mounted on a transverse to the transport direction extending shaft and unwinds with the Trarssportgeschwindigkeit the metal profiles in the transport direction. Suitably, the drive of the separating strip supply roll is derived from the transport movement of the metal profiles.

According to another feature, a separating means for separating the trailing end of the extending composite profiled strand from the extending end of the adjoining composite profiled strand is provided behind the last casting device. In this case, the separating device from a driven flying legend or the like. consist.

For the production of composite profiles with a plurality of insulating zones, respectively, a plurality of casting devices corresponding to the number of desired insulating zones are advantageously arranged transversely to the transport device, devices for removing the bridging web (s) and separating agent supply rolls are provided.

Webs 10,11 and 12,14 and 13,15 (Fig. 8 and 10) and 10, 11, 23 '(Fig. 11) or 10', 11 * (Fig. 13) have and the advantage of provide greater stability and good dimensional stability during the extrusion process. This advantage has a positive effect especially for large profile cross sections. But even with smaller profiles often output cross sections are required, which have more than one Oberbrückungssteg between two metal profiles.

9 and 10, an output profile cross section is shown, the three juxtaposed metal profiles 2,3 and 3 ', of which the metal profiles 3,3' by a Oberbrückungssteg 12 and the metal profiles 2, 3 'are connected by a Oberbrückungssteg 13 As can be seen, the bridging webs 12, 13 are arranged separately next to one another by the metal profile 3 ¹ . But it is also possible to provide in each insulating zone A or B in the example of FIG. 9 based on the embodiment of FIG. 8 instead of a Oberbrückungssteg two or more, as in the cross section of FIG. 10 by broken lines 14, 15 indicated.

FIG. 11 shows a variant for an output profile cross-section with two bridging webs 10, 11 arranged one above the other, with the finished composite profile according to FIG. 12 having two insulating core strips 16, 17, 18 instead of two insulating core strips arranged one above the other.

Another composite profile variant with three Isolierkernleisten 16 ', 17', 18 "is shown in Fig. 22 can be seen. This composite profile execution is in practice preferably used when it comes to produce relatively large cross-sections, the output of profile cross-sections of two or more metal Oberbrückungsstege 10 ', 11', 11 ", as shown in FIG.

The production according to the invention of a composite profile from an initial profile cross-section according to FIG. 1 proceeds in the following method steps:

First, the two metal profiles 2, 3 are extruded as a unitary profile unit and pretreated in a known manner (e.g., by anodizing). In a subsequent process stage (FIG. 2), the gutter bounded laterally by the mutually facing walls 19 of the metal profiles 2, 3 and below by the upper bridging web 9 is formed

20 by means of a casting head 2: 5 filled with a commercially available thermoplastic material 21 as insulating casting material, the Oberbröckungssteg 9 also serves as a bottom cover of the groove 20. After the plastic

21 has set in the gutter and is solidified to the Isolierkernleiste 6, is on a partial width of the upper. bridging web 9 between the metal profiles 2, 3, e.g. by a saw 22, a router or the like. (Fig. 3). Subsequently, the profile is turned around its longitudinal axis by a rotation through 180 ° (FIG. 4). The position of the profile after turning is shown in Fig. 5. Thereafter, between the metal profiles, the separating strip 8 is introduced (Fig. 6), which rests at a distance from the height of the cavity 7 on lateral web sets 23 of the metal profiles and has the task, the Ground cover of another channel to form. In a last method step, the channel 24 is poured out of a casting head 29 with the plastic 21. After curing, the second Isolierkernleiste 5 is created and the composite profile ready for further processing.

The procedure described with reference to the output profile cross-section according to Fig. 1 takes place in a corresponding manner in the production of the other composite profiles shown.

236880 2

In the output profile cross-section of Fig. 8, the removal of the two superimposed bridging webs 10,11 carried out by means of the saw 22 shown by broken lines in a single operation, ie both bridging webs are separated simultaneously or approximately simultaneously. The separation can of course be done in other suitable ways, for example by cutting, tearing off, etc.

In the production of composite profiles with more than two juxtaposed metal profiles, as shown in Fig. 9, both grooves are each filled simultaneously with the plastic 21. For this purpose, instead of the one casting head 25 required in FIG. 2, two casting heads 25 arranged in parallel and arranged in parallel are required. Correspondingly, in these profiles, the adjacent or superimposed bridging webs 12, 13 and 12, 14 and 13, 15 in FIG. 10 are simultaneously removed after forming the insulating core strips 6 ', 6 "by parallel adjacent legends 22. Basically, in composite profiles with two or more isolation zones A and B it can be assumed that in each case all the same operations, such as pouring the gutters, removing the bridging webs, introducing separator bars during the procedure can be performed simultaneously.

The production of the composite profile of Figure 12 from the Ausgangssprofilquerschnitt of FIG. 11 is carried out according to the same process steps, as described with reference to FIGS. 1 to described, with the only difference that after forming the Isolierkernleiste 18 in the first filled with plastic channel and after removal of the Oberbrückungsstege 10,11 and turning the profile instead of an additional groove two grooves one after another with plastic

16, 17 are poured out, immediately after the casting process, the associated separating strips 8 ', 8 "as bottom covers for the grooves 24' and 24 have been placed on the web projections 23 '.

14 to 22 a process flow is shown, according to which, in contrast to the described Hersteilungsweise for a composite profile with three Isolierkernleisten corresponding to FIG. 12, not two channels after turning the metal profiles are filled with plastic, but only one channel, while the other two Isolierkernleisten be made before turning. The illustration in Fig. 13 is intended to clarify that, for reasons of extrusion, basically all conceivable starting cross sections can be provided with a bridging web 11 ", which closes the profile at least on one outer side and must therefore be removed again before the casting process begins 14, first the middle channel 76 on the casting head 25 is filled with plastic, so that the insulating core strip 17 'is formed (FIG. 15) .A separation strip 8 "" is then placed on the web extensions 23 located above it (FIG. 16) and the gutter 77 thus formed from the casting head 25 'filled with plastic (Fig. 17) .Then the webs 10', 11 'with the aid of the saw 22., Separated (Fig. 18), the profile turned ( Fig. 19, 20) and the last groove 78 formed by placing a separator bar 8 (Fig. 21) and this filled from the casting head 29 with plastic (Fig. 22).

In Fig. 23 the production of a composite profile according to Fig. 7 is shown again schematically. The first pouring head ajm filling the respective uppermost gutter of each profile is 2.3 with 25, located in the conveying direction 26 behind the saw 22 turning station with 27, the device for introducing the separator bar with 27 and the

Casting head for filling the last guttering channel is denoted by 29.

Compared to the process sequence shown in FIG. 23, FIG. 24 shows an alternative process variant, which differs from the first one in that the composite profile 2, 3 after turning in the turning station 27 from the first transport direction 26 by parallel displacement in the direction of arrow 30 in a second transport path is transferred, in which the profile is transported counter to the conveying direction 26 in the direction of arrow 31 in the direction of the device 28 for introducing the separating strip and the second casting head 29. In this method, the turning and passing of the profiles on the second to the first parallel transport path 'simultaneously done, for example, the turning operation by hand or a suitable rotary device not shown and the transverse transport of the profile in the direction of arrow 30 via a on rollers 32nd stored, driven conveyor belt 33 takes place. This variant of the method is preferably used in practice when the available length of a production hall is not sufficient for a straight-line method sequence according to FIG. 23.

The device for producing a composite profile in the embodiment according to Fig. 27, which is identical to the cross-section shown in Fig. 7, has a horizontally arranged work table 24 (Fig. 25,26), which is supported with feet 35 on the 3oden , The work table 34, which also consist of any other suitable base, for example, can be divided into several tables (Fig. 23), has a support surface for the metal profiles 2,3, during their processing into composite profiles 1 on the predetermined transport path in Pfeiirich ·

tion 26 between rollers 36,37 are transported. The rollers 36,37 are mounted on vertical shafts 36 ', 37' on the work table 34. The rollers 36 on one side of the table are non-rotatably mounted on the shafts 36 'and driven by these, while the arranged on the other side rollers 37 are unpowered and only as an abutment for the driven over the driven rollers 36 by friction metal profiles 2, 3 serve. The drive source for the rollers 36 is a motor 38, the drive pinion 39 via a gear 40, a shaft 41 drives. The shaft 41 carries on its length at a distance of the rollers 36 bevel gears 42, which come with corresponding bevel gears 43. The bevel gears 43 are keyed onto the shaft ends 36 'projecting below the work table 34, which transmit the drive motion emanating from the motor 38 to the rollers 36.

Located above the work table 34 is a first pouring device 25 consisting of a pouring head 25 'and a discharge nozzle 25 ".The pouring head 25 communicates with a casting resin reservoir 45 via a line 44 and is adjustably suspended on a support 46 which is secured to the work table 34. are used as casting material known casting resins, which are discharged in liquid state from the discharge nozzle 25 "of the caster and solidified after a short setting time.

Suitably, the saw 22 is suspended in height adjustable according to the double arrow 48. The saw blade 22 is designed so narrow that it has sufficient clearance in the cavity 7 (Fig. 3) between the profiles 2.3 and during transport of the metal profiles in the direction of arrow 26 of the metal bridge bridge 9 can be continuously removed from the bottom profile unhindered , Via a rotatable spindle 74 suspended from the frame 72.73 roller 75 (Fig. 29) serves to guide the composite profile in the vertical direction, in particular for receiving the back pressure during the removal Oberbrückungsstege aer.

Once the returning end 49 of the composite section 2.3 has passed the saw 22, the composite profile is in the turning station 27, on the length of neither transport rollers 36 nor the corresponding counter-rollers 37 are present, so that the profile by hand by means of a suitable, not shown rotating device about its longitudinal axis from the position shown in Fig. 4 in the position shown in FIG. 5 can be rotated.

Immediately behind the leading end 50 of the metal profile outside the turning station 27, a supply roll 51 is arranged for the separating strip 8, which is continuously introduced into the groove 24 during the advancing movement of the composite profile at the designated location. The arranged at a distance above the groove 24 winding 51 is mounted on a transverse to the transport direction 26 extending axis 52 which is freely rotatably received in bearings 53,54, which are supported on the support 34 on the work table.

In the transport direction 26 behind the .Red strip supply roll 51 and the separating strip guide 56 is also a freely rotatably mounted on a pivot lever 60 pressure roller 61 is arranged, which serves to press the separator bar 8 on the support webs 23 for the gutter shelves to to achieve a uniform and close system of separating strip 8 along the support webs. The pivot lever 50 is mounted at its end facing away from the pressure roller 61 on an axis 62, whose two ends are supported in bearing shells 53, which are fastened via supports 54 on the work table 34. To exert the necessary pressure on the separator strip 8, the pivot lever is spring loaded or weighted tsbelast.

In the transport direction 26 behind the separating strip supply roll 51, the second pouring device 29 is arranged »which is constructed according to the first pouring device 25 and accordingly has a pouring head 66, a discharge nozzle 67, a connecting line 58, a casting material reservoir 69 and a holder 70a. From the casting head 66, the plastic 21 is discharged into the channel 24.

The metal profiles 2, 3 filled with casting material in the described manner are transported on the work table 34 at a constant conveying speed after passing through the last casting device 29.

Since the only connection between the two profile strands is formed by the two now solidified partial insulation cores 5, 6 and the continuous separating strip 8, the kinking or tear-off point is located in the partial insulating cores and the separating strips. It is of course also possible, instead of separating device described the contiguous profile strands at their joint by a dash-dotted line in Fig. 25 indicated suitable saw 70 to be arranged then expediently perpendicular to the transport direction (arrow 71) should be arranged to move without interruption of the transport to be effective.
