FIG. 12a is a perspective view of the film of Fig. 12.

In the drawing, the formable or elastic film for shielding against radiation, currents and / or electrical fields and / or for isolating or for galvanically separating electrically conductive or conductive parts and / or for fastening is shown in FIGS. 11-13 with 1 of parts, in particular of components, pipes or electrical lines 2 shown on egg ner base 4 , wherein at least one side of the film 1 is provided for attachment to the base 4 with egg ner adhesive surface 5 .

The film 1 can also be used as a fastening device and simultaneously or separately as a shielding or insulating device. The indicated in Fig. 1, 2 part 4 may be part of a floor, a glass surface or a developer, on the surface of a component, a cable or an electrical line 2 fi xed by means of the fastening device or the film 1 or permanently can be attached.

The film 1 illustrated in FIGS. 1 to 3 is composed of a moldable, soft, high-strength composite mate rial 11 fen with at least a continuous tacky surface, or two or several adjacently arranged adhesive surfaces parallel to one another duri and extending over the entire length the film 1 he stretch (see. Fig. 5), which is designed as an endless film strip and can be wound onto a winding core.

According to another example, the adhesive layer 5 consists advantageously of a UV-resistant material, which also has the property that it can be removed from the surface together with its carrier without residue. Since no residues remain, after the removal of the film 1 , which was applied to the surface of the bottom 4 by means of this adhesive, there is no need to carry out any post-treatment of the bottom 4 .

According to Fig. 1 11, the fastening means 1 of the multi-layer laminate or film strip which is produced as a cross-laminate. The laminates or the individual layers 6 , 7 , 8 can be equipped in one direction with a greater tensile strength, for. B. in the longitudinal direction of the film. With reference to the directional information, the individual layers can be aligned differently with respect to the adjacent layer, ie applied crosswise offset. A perspective view of the individual layers of the fastening device before the assembly is shown in FIG. 6, the individual lines reflecting the orientation of the film or the lines of force or the direction with the greater tensile strength. The melt or an adhesive can be introduced between the two layers 6 and 7 , which creates a firm connection between the two layers 6 and 7 .

The composite material 11 , which (according to FIG. 1) is formed from the two layers 6 , 7 , can consist of a polymer material or of polyolefin material or in particular polyethylene. Characterized in that the composite material 11 is formed from two layers 6 , 7 , one obtains a large resistance in the longitudinal and transverse directions or tensile strength with a very high degree of deformation. Such a composite material 11 can readily be formed as a pliable, soft adhesive tape ( FIG. 5) which can be wound onto a core (not shown in the drawing).

According to another embodiment, the one individual laminates or layers in the longitudinal direction or in glued in the same orientation or ver bound, there are other advantages. That way provided adhesive tapes can be applied without great effort Tear the wall sideways and therefore without cutting tools cut to the required length. By the The tape will tear only slightly when torn stretched in the direction.

As can be seen from Fig. 1, the Befestigungsein direction or film 1 as a cable duct 12 can be shaped and varied as desired. The height and width of the cable duct 12 can be arbitrarily determined by the easily deformable film 1 and can also be changed after attachment to the base layer 4 by loosening one half of the band. The shape of the cable duct 12 is obtained in an advantageous manner in that the composite material or laminate 11 is provided with at least two adhesive strips 5 which are spaced apart and, depending on the type of load, between 10 mm and 100 mm, in particular 20 cm, can be wide. The adhesive strips 5 are preferably provided in the edge region of the film 1 in the longitudinal direction. The two adhesive strips 5 are applied with such a large distance on the surface 3 of the bottom 4 that the semicircular cable duct 12 forms, in which various components can be accommodated and fixed on the surface 3 of the bottom 4 . In the embodiment according to Fig. 1, 5 in the cable channel 12, the cable 2 is provided.

So that the cable 2 is fixed even better on the floor 4 or cannot be easily pulled in the longitudinal direction through the cable belkanal 12 , if this is not desired, the laminate or composite material 11 has a third adhesive layer 10 , which is a fixed Connections between the laminate 11 and the cable 2 produces.

In order to further improve the strength under certain types of stress and to achieve full shielding, the composite material can be produced from three or more layers. In the embodiment shown in FIG. 2, the composite material or laminate 11 consists of three layers 6 , 7 , 8 , which can have different strength and are formed from a composite of polyolefin / metal. The two outer layers 6 , 8 are formed from a plastic material or from polyolefin or, in particular, from polyethylene, the middle layer 7 consisting of another material, for example a metal fabric, a metal strip or a glass fabric.

It is also possible for the third layer 7 to consist of Cu. For this purpose, a penetration 13 can be provided in the outer layer 8 or 6 made of plastic or another insulating material, through which a conductive cable 14 is guided, which connects the middle Cu layer 7 or the copper strip to earth 15 . So that the outer layers 6 or 8 do not tear in the area of the penetration 13 , a reinforcing element or an eyelet 17 is inserted through which the cable 14 is guided. The eyelet 17 can also be clipped into the layers 6 , 7 , 8 ( FIG. 2) in a simple manner. Furthermore, the outer layer can be pierced in a simple manner and then the conductive or outer conductive part of the layer can be connected to the metal foil and the cable 14 can be brought up to the metal foil. The outer layer can advantageously be equipped with graphite pigmentation. In this way, a plastic film can be made conductive and the metal layer 7 'can be dispensed with.

According to another example, it is possible to press a small worm screw or a rivet 17 ( Fig. 2a, b described below) into the film 1 , or to push the upper film 8 with a stamp so far that an electrical connection to the middle Layer 7 is made. This has the advantage that the film 1 is not only used for fastening components who can but also as a shielding device. In this case, the device also serves to avoid mutual interference of lines, assemblies, devices and systems by electrical or magnetic fields. The layer 7 provided between the two outer layers 6 , 8 , which can preferably be made of Al or CU, but also of another suitable material, is advantageously used for this purpose and is electrically conductively connected to ground. The shielding effect is based on a charge shift through which the envelope becomes an equipotential surface and thus the interior of the envelope is field-free. In this way, the slide 1 fulfills several functions; it is used to fasten components and cables and can also be used as a shielding or isolating device. Likewise, the composite material 11 can only be used as a shielding or insulating device and connected to the individual components.

Advantageously, the conductive layer 7 , according to FIG. 2, lies between the two outer layers 6 , 8 made of plastic material. Depending on the application, one of the outer layers 6 , 8 can also be conductive.

Referring to FIG. 1, the two layers 6, 7 do not tend lei, although it may be advantageous that at least one layer is conductive 6 or 7.

As can further be seen from FIG. 2, the cable 14 can also be connected to a pulse generator 19 via a normally open contact 18 , which supply 20 can be connected to a power supply. In this way, the multi-layer composite material 11 according to the invention can be used for digital transmission of data and data, the data being modulated in the pulse generator.

It is also possible that only one or two layers have different strengths. There is also the possibility that two layers of polyethylene and the third layer consists of a plastic poor or plastic-free material. In a geous manner, the third layer 7 is embedded between the two outer plastic layers 6 and 8 according to FIG. 2.

As can be seen from FIG. 1, the lower layer 6 has two or more adhesive strips 5 which are arranged at a uniform parallel distance from one another and extend in the longitudinal direction of the film 1 (see also FIG. 5).

The composite material 11 or the polyolefin material can have a thickness between 0.035 mm and 0.5 mm, in particular in particular between 0.08 and 0.15 mm.

In Fig. 4, a three-layer composite 11 is provided, the third layer 7 is embedded between the two layers 6 and 8, in particular made of polyolefin, which is made of metal, in particular Al and / or Cu or from a metal fabric strip, for. B. copper mesh can exist.

The film 1 ( Fig. 4) is suitable as a Abschirmeinrich device for one or more electrically conductive cables 2 , z. B. as a wiring harness. It is as flexible as the cables themselves, which means that they can be laid even with very narrow cable routings to suit difficult spatial conditions.

For this purpose, the lower layer 6 can be provided on the inside with a continuous adhesive surface 5 or with two or more, evenly spaced adhesive surfaces 5 , by means of which the lines 2 can be held together or can also be fixed on the surface 3 of the component or base 4 .

The film 1 can be produced in different ways. For example, a film made of polyethylene material can first be produced and a metal or aluminum or copper foil or copper tape fabric can be applied in a second step, a liquid polymer material being introduced as a binder between these two layers in the melt casting process. This polymer material has different strengths, so that the described tearing effect occurs when the film is cut who should. Lateral tearing is then facilitated if the entire film is provided with ribs or ribs at short intervals. If the film is in the form of a cross laminate, this part is not required, but such a film has a very high resistance, in particular a high tear and puncture resistance.

One or more narrow metal strips can be provided between the two layers 6 and 8 . The metal strip or metal thread extends over the entire length of the fastening device or film 1 . The width of the metal strip can be significantly smaller than the width of the two layers 6 and 8 .

The film 1 can be provided with a continuous adhesive surface or with at least two adhesive strips running parallel to one another or with numerous adhesive strips arranged at a distance from one another, which extend over the entire length of the film and extend parallel to one another. If, for example, more than 2 or 3 adhesive surfaces are provided on the underside of the film 1 , several cable ducts 12 running parallel to one another can be formed on the base or the floor 4 with only one single film 1 .

The same film 1 can also be used as a shielding device if it or a layer of the film has shielding properties. This layer can be provided as an intermediate layer between the outer and inner layers 6 , 8 according to FIG. 2. In this application, it is also possible to provide the shielding layer as the outer layer. In another variant, more than three layers can also be provided, the layers being alternately formed as shielding layers and as insulating layers.

A film designed in this way can be fixed in the vicinity of electrical lines with low or high voltage by simply pasting it onto a solid surface and additionally used as an insulating material ( FIG. 5).

Furthermore, the inner film or the metal film between two layers can also be grounded by exposing them to dissipate surges.  

It can also be used as a voltage carrier for signal or Serve leakage currents.

In the case of a multilayer structure, for example the following layer variations are possible: layered structure, the layers of polymer, Metal or glass mesh, again polymer and from one Glue exist.

It is also possible to use polymer, metal or glass mesh, Polymer, metal or glass mesh, polymer and ultimately To provide glue or other layers.

The individual layers can either be longitudinal or be connected with each other in a cross-connection. Depending on The structure of the individual layers is different shielding and insulation values. By such a way Formed foils can be on control and measurement stands electrical devices in the simplest way shield afterwards, without structural changes to have to make.

By laminating the lead foil with polymers he gives itself an easily removable, easy to process Foil that is tear and break-proof. Besides, will the release of pollutants excluded.

Advantageously, the glue is difficult to ignite bar and self-extinguishing.

It is also possible to use polyolefin cross lamination insert and the intermediate layer, for example the Metal layer, through polio melting between the two to laminate spiral-stretched polymer films.  

It is also possible to add more layers in the description as a spiral film or as a spiral cut film Apply flat sheet or as a complete cross laminate gene.

Through special additives or additives, for example metallic additives, the polymers, in particular the polyolefin films are made electrically conductive the. Various can be advantageously Produce material films or composite films. The after The examples listed above can be varied as required become.

The schematically shown in Fig. 2 formable, formed from several layers 6 , 7 'and 8 film, which is used to shield radiation, currents and / or electrical fields and / or to isolate or galvanically separate electrically conductive parts or conductive parts and / or is intended for fastening parts, in particular components, on a base is illustrated in detail in FIGS. 11, 12 and 12b, 13.

The upper layer 8 shown in FIG. 2 is designed as a PE layer and, according to FIG. 11, consists of two transverse layers 26 a and 26 b, which are connected to one another by a PE melt 25 , so that in a certain area the two transversely stretched foils 26 a and 26 b can move against one another if the foils change in length due to different thermal expansion or tensile stress. The PE melt 25 thus forms a floating connection between the two layers 26 a and 26 b and also with the other interconnected layers, as will be explained in more detail below.

The stretched layer 26 b ( FIG. 11) is also connected via a further PE melt 33 to the metal foil 24 labeled 7 ′ in FIG. 2. On the underside of the metal foil 24 there is a further PE melt 23 which serves to hold the adhesive designated 5 in FIG. 2 and 21 in FIG. 11. The adhesive 5 , 21 can be applied either in strips or over the entire area on the underside of the PE melt 23 . According to FIGS. 2 and 11, the adhesive 5 or in FIG. 11 the adhesive 21 can be applied to the PE melt 23 in two adhesive strips arranged at a distance from one another.

In the production of the transversely stretched film 26 a and 26 b ( FIG. 7), a spiral-cut flat web (see page 24) is obtained, which is cut out spirally from a film tube 52 according to FIG. 7. Before the film tube 52 is cut out as a flat web, it is stretched according to arrow 54 in the longitudinal direction of the axis of the tube film according to arrow 54 . As a result, the molecular structure of the film is particularly aligned, and if one connects the individual molecular lines, a stretching line 41 is obtained which intersects the longitudinal edge of the film 26 a and according to FIG. 10 at an angle of 45 °. It follows that the stretching line 41 of the upper layer 26 a line 42 the stretching of the underlying film 26 b in FIG. 10 at an angle of 90 ° intersects.

The layer 26 a or 26 b or the film web 8 b or 48 is cut out as a spiral path from the film tube 52 according to FIG. 7 by means of a knife (not shown in the drawing) along the spiral line 53 , so that then according to FIG. 10 result in two spiral-cut film webs or layers 26 a and 26 b, which are firmly connected to one another via the PE melt 25 according to FIG. 10, the two stretching lines 41 and 42 running opposite to one another and thus also the alignment of the molecular chains of the layers 26 a and 26 b. The joining of the transverse stretched spiral tracks or layers 26 a and 26 b also takes place for the connection of the individual layers according to FIGS. 12 and 12a.

In FIGS. 8 and 9 two cut out of the film tube 52 transversely stretched layers are shown a b 26 and 26 of FIG. 10, as already explained about the PE melt 25 can be firmly interconnected.

In FIG. 6, the manufacturing method of a film composite 48 is shown, of a PE Fusion 25 and the layer 26 consists of layers 26 b. The two film webs 26 a and 26 b run from a roller (not shown in the drawing) and move according to FIG. 6 in the direction of arrow 50 , being guided over rollers 56 and 57 and then being compressed over rollers 58 and 59 , the PE-Fusion 25 is introduced and thereby creates a firm or floating connection between the two layers 26 (film web) and 26 b (film web). In Fig. Film or illustrated with 48 6 of the film composite 48 is indicated in Fig. 2 by the layer 8 can also consist of two transversely stretched laminates, which are fixedly connected to each other via a PE melt.

A further film composite is shown in FIG. 13, which consists of a total of 10 layers. The upper film composite 48 consists of the two layers 26 a and 26 b connected via the PE melt 25 , followed by a further PE melt 33 with a metal foil 24 , which in turn via a PE melt 35 with another film composite 66 is connected. The film composite 66 also consists of the two layers 26 a and 26 b connected via the PE melt 25 . On the bottom or outer layer 26 b there is again the adhesive 21 , which is applied either over the entire area on the underside of the layer 26 b or according to FIG. 2 in strips arranged at a distance from one another. The adhesive 21 corresponds to the adhesive layer 5 in FIG. 2.

FIG. 12a shows the film composite 32 from FIG. 12 in a perspective view. The film composite 32 consists of an upper non-stretched film 32 a, which is fixedly connected via a PE melt 35 with the metal foil 34 b via a PE melt 35 with a further non-stretched film 32 is firmly connected. The layers 32 a and 32 b essentially correspond to the layers according to FIGS. 6 and 8. In FIGS. 1, 2 on the lowest side of the layer 32 b there is the adhesive 31 , which is either in strips or over the entire surface on the underside of the layer 32 b is applied. There is also the option to leave out the glue.

Fig. 11a shows that one of the layers 26 a is provided with a paper layer 36 which adheres to the layer 26 a via an adhesive 37 .

FIG. 2a, b show a hollow rivet made of metal 17 with a tubular rivet shank 30 and a rivet head 27th The lower end of the rivet shaft 30 is slightly corrugated, the arches being identified by the radius 29 . The lower, outer edge forms a cutting edge 28 which, as mentioned, has a wavy course and when the hollow rivet is inserted into the film composite, which can consist of three or ten layers, the films 6 , 8 , FIG. 2, or 26 a, 26 b or 32 , Fig. 11-13, cut so that the foils are not pulled down with the rivet and thereby cover the metal foil. The rivet offers through the cutting edge 28 the possibility to pierce the plastic films so that the layer 6 , 8 retains the position shown in FIG. 2a unchanged, so that the hollow rivet can make an electrical connection between the metal foil 7 'and the electrical cable 14 . After the insertion process, the lower, protruding end of the hollow rivet 17 is flanged, and a closing collar 22 is created which, together with the rivet head 27, fixes the hollow rivet in the film 1 .
