Definitions

  • the invention relates to a film which is provided with waves so that the films is stretchable.
  • the invention further relates to a manufacturing method for the film together with the production means and a method of use.
  • Connecting or end bands for a roof, chimney, window, floor and / or a wall of a building comprise a film of the type mentioned.
  • a connecting band or a connection element consists of a weather-resistant surface made of metal and an adhesive bottom.
  • the connecting element or the connecting strip is adhesively bonded to the transition by means of the adhesive underside. This ensures that no moisture can penetrate through the transition into the building.
  • the surface made of metal has a waveform (comparable to a corrugated metal sheet), so that the already adhered tape can be stretched and thus subsequently pushed into niches and the like. If such a band is pressed in, the waves become flatter and the film stretches accordingly. If necessary, therefore, a band can be stretched in general in order to be able to adapt to the surface design of a building.
  • a film of the type mentioned above is also used in ventilation elements for ridge and ridge for a building.
  • Such a so-called ridge and ridge roll has an air-permeable web, which is laterally framed by a respective film of the type mentioned.
  • the DE 101 39 273 A1 discloses such a ridge and ridge roll.
  • the films can only be stretched in one direction.
  • the films are particularly well flexible only in the direction of the waves. If a film is to be bent perpendicular to the "propagation direction" of the shaft, so this is a considerable effort required, since even by comparison with a flat sheet additional counteracting static forces must be overcome by the waveform even. If such a wave-shaped film is used, for example, in a transition from a roof to the chimney, a bending of the film perpendicular to the direction of propagation is required with proper handling. Because only then can the film be mounted so that the troughs form from top to bottom leading grooves that allow an outflow of water. Otherwise, there is a risk that water will remain in the troughs and permanently damage moisture.
  • the object of the invention is to provide a stretchable film that can be further simplified compared to the above-mentioned prior art to existing geometries in a building.
  • the object of the invention is also to provide a simple Process for the production of the film together with a device which serves for the production of the film.
  • the present film waves and / or wrinkles, so that the film is stretchable, in particular in the longitudinal and transverse directions of the film and not only in one of the two directions.
  • there is at least one rectilinear band-shaped area which is free of undulating elevations. On both sides adjacent to this band-shaped area there are undulating elevations. This is achieved by compressing or rolling wave-shaped elevations, so that along the band-shaped area compressed overlaps of the film are present.
  • a termination or finishing band is applied to a transition from a roof to a chimney
  • there are regular building codes that dictate how far the termination or termination band must extend up and down from the roof to the chimney transition For example, 150 to 170 mm are regularly prescribed. At least such dimensions are useful to ensure a seal.
  • the provision of a band-shaped area which is free of undulating elevations now makes it possible to comply with such building regulations more easily. If, for example, it is stipulated that a 150 to 170 mm wide region of the film must be glued up and down from a transition, then, for example, one will be at least approximately 300 mm provided wide film having in the middle parallel to the edge region a straight, band-shaped area which is free of undulating elevations.
  • this area can be bent particularly easily.
  • the connecting or closing strip can now be folded along the band-shaped area, which is free of undulating elevations, and placed with the kink on the transition to be covered.
  • the film can be stretched in all directions along the major surface of the film by the undulations or wrinkles in one embodiment, it can be particularly easily adapted to complicated geometries.
  • the film can be pressed into niches without changing its other position, regardless of the waveform.
  • the claimed film can not only be deformed and pulled particularly easily in a preferred direction, but in the above-mentioned sense it can be stretched and deformed as desired in a particularly simple manner.
  • the film can be very easily pressed on corners or edges and / or adapted.
  • stretching movements can also be superimposed in two different "preferred" directions that are perpendicular to one another, for example, stretching along an intermediate direction, for example along a diagonal, is likewise possible.
  • a claim film is preferably designed as a connecting band or cover strip for a roof, fireplace, windows, floor and / or a wall of a building.
  • the film can also be used as a bending groove in a roof. It forms then the transition between two rising slopes in a roof.
  • the film is preferably provided with an adhesive layer on one side, so as to be able to secure transitions in a building by means of the adhered film against ingress of moisture and moisture, as an adhesive layer, for example, a butyl layer is provided.
  • an adhesive layer for example, a butyl layer is provided.
  • Another typical example is the use of a foil on a roller for ridge and burr ventilation on roofs.
  • the films are used in particular in the form of long, narrow bands, which are attached to both sides of a long, narrow air-permeable belt and / or fabric.
  • the one-piece film is in particular made of stainless metals, such as aluminum, lead, copper, zinc or a suitably deformable steel.
  • stainless metals such as aluminum, lead, copper, zinc or a suitably deformable steel.
  • the film is preferably coated with lacquer on one or both sides.
  • a coating on one side protects against corrosion and other environmental influences.
  • the paint is also colored to the other surface, so for example adapted to the color of the roof, so as to meet visual requirements.
  • the paint layer on the other side (underside) protects against corrosion.
  • the corrugations and / or folds run parallel to further undulations and / or folds.
  • This symmetrical structure can be easily manufactured, as can be seen from the manufacturing method described below.
  • the production is particularly simple if one or more waves run in a "wave propagation direction" and at the same time a plurality of folds are provided which extend parallel to the direction of the direction of the wave propagation.
  • Propagation direction is understood to mean a direction that must be taken to follow from any starting point on the film of the waveform.
  • a wave in the sense of the invention is present in particular if the course essentially corresponds to a sinusoidal shape.
  • a fold in the sense of the invention is in particular, if there is a course of the film through which an acute angle is included. In particular, there is a fold when the film is shaped so that portions of the film overlap.
  • this is corrugated in one direction.
  • the corrugated shape is formed in particular by a plurality of mutually parallel shafts, which are separated by folding.
  • the folds are designed so that left and right of a wave overlapping areas of the film arise.
  • the film is folded alternately to one and to a direction opposite thereto.
  • one shaft can be offset relative to the two adjacent shafts, for example by half a wavelength.
  • the narrow band-shaped region is formed by flat-rolling such a shaft, which is separated by folding of adjacent waves is, so that subsequently there is a band-shaped course which is fei wavy elevations. Instead, this band-shaped region has at regular intervals, corresponding to the previous wavelength, wrinkles which are perpendicular to the course of the band-shaped region. If the band-shaped region runs parallel to the waves and if the individual waves are separated from one another by folding, then the possibility of a variable stretching of the film is not adversely affected. Any other direction of the band-shaped course would have the consequence that the possibility of stretching the film close to this band-shaped course would have been reduced.
  • the film of the type mentioned above is produced in a simple manner by first providing a rolling device which consists of a pair of rollers, each having a wavy surface in the circumferential direction.
  • the shafts of the two rollers are toothed together in the manner of a gear.
  • the film will pass the roller in a first direction, thereby producing the wave form in the film. If the film is subsequently passed through the pair of rollers once more and now perpendicular to the first direction, a film is produced which has a multiplicity of waves running parallel to one another and which are separated by folding in the sense of the invention.
  • Each shaft may be offset from an adjacent shaft. The offset between two adjacent shafts depends on the particular set clearance between the rollers, as practice has shown.
  • the width of the roller used corresponds to the width of a shaft which is separated by folding parallel waves.
  • the roller is then guided along such a shaft. This ensures that only one shaft is compressed and the band-shaped area is desired only narrow.
  • the roller is above such a shaft guided on either side by higher lying waves. This minimizes production errors.
  • an adhesive layer is applied to one side of the film. If the film is to be used at an angular transition which results in the film having to be bent in such a way that the visible, overhead region of the film, which is free of the sticky layer, has to be folded up, the side is preferred the film provided with an adhesive layer to which the band-shaped compressed area immediately adjacent. The previously compressed shaft was thus compressed by the roller in the direction of the side to which the tacky layer is now applied. In this embodiment, the intended bending of the film is optimally facilitated. If the film is bent or bent the other way round, the sticky layer is applied in the opposite direction in order to optimally facilitate the intended bending.
  • the film of the invention thus produced is provided with a uniform surface pattern except for the compressed band-shaped portion (s). Since the wrinkles and undulations are arranged very regularly, the film can be deformed or stretched very uniformly in all possible directions without much effort. This also applies to intermediate directions that are not perpendicular or parallel to the folds.
  • a rolling device which has two roller pairs arranged one behind the other.
  • the first pair of rollers has in the circumferential direction in each case wave-shaped surfaces which are interlinked.
  • the subsequent second pair of rollers has in the circumferential direction in each case grooves which are interlocked with each other.
  • the dimensioning of a groove and the distance to an adjacent groove substantially corresponds to the dimensioning which has been provided in the shafts of the first pair of rollers.
  • the inventive production of the film succeeds in a single pass.
  • it does not have to be first removed from a rolling mill and then redirected in a new direction by the rolling device.
  • a particularly simple, inexpensive and fast production is guaranteed.
  • the film is thus preferably produced by means of a rolling device which has two pairs of rollers.
  • the one pair of rollers is provided in the circumferential direction with shafts and the other pair of rollers in the circumferential direction with grooves, each tooth-like mesh.
  • FIG. 1 shows a first section through a preferred rolling device, which can also be referred to as a folding device.
  • a film 1 is passed through the rolling device, which has at least four profiled rollers, two rollers 2 and 3 are combined to form a first pair of rollers. Two further rollers 4 and 5 are combined to form a second pair of rollers. Shown is a side view of the device.
  • Bearings 6 are provided to rotatably support the rollers 2 to 5.
  • the pairs of rollers are arranged one behind the other so that the film passes first the first pair of rollers and then the second pair of rollers.
  • the type of profiling is determined by a supervision according to FIG. 2 clarified.
  • the visible in the top view roller 2 has a waveform in the circumferential direction.
  • the visible in plan roll 4 has grooves in the circumferential direction.
  • the roller 3 is also provided on the surface with waves in the circumferential direction.
  • the shafts of the roller 3 are toothed with the shafts of the roller 2 as in the case of two toothed gears.
  • the roller 5 has grooves which are adapted to the size and position of the grooves of the roller 4, that the grooves of the two rollers are also interlocked.
  • the material 1 passes the first pair of rollers 2 and 3
  • the surface of the film is provided with a wave form. If this then selected surface passes the second pair of rollers 4 and 5, the shaft is laid in a plurality of waves, which are separated by folding. Regularly arises in a simple and cost-effective manner, a film having the surface according to the following figures.
  • FIGS. 3 and 4 show the surface of a film that in the in Figures 1 and 2 indicated manner was produced.
  • the surface has according to the FIGS. 3 and 4 a plurality of shafts 7 and 8.
  • a shaft 7 is located between two shafts 8 and is separated from the shafts 8 by folding 9.
  • Waves 7 and 8 have the same wavelength. They are arranged offset from each other by half a wavelength.
  • a wave trough of the wave 7 thus borders on a wave crest of a wave 8 FIG. 4
  • the shape of each fold 9 is additionally shown.
  • a wave crest of the shaft 8 is folded at its edges so that pocket-like recesses arise.
  • a section perpendicular to the direction of rotation of the shaft thus results in a zig-zag shape of the film, as by means of the reference numeral 10 in the FIG. 4 highlighted becomes.
  • the arrows 11 indicate the direction of each wave.
  • the folds 9 are parallel to this direction.
  • At least one roller is preferably guided along a shaft 7 located lower.
  • this shaft 7 is pressed onto a subjacent underlying and so compressed.
  • the roller has a width which corresponds to the width of a shaft 7. It arises so in the Fig. 5 shown film having a narrow band-shaped portion 12 which is free of undulating elevations. Instead, this region 12 at regular intervals wrinkles 13 which are perpendicular to the course of the belt 12.
  • the Indian FIG. 5 Rear portion of the film can now be easily folded around the band 12 according to the arrow 14 upwards.
  • a sticky layer 15 is expediently on the bottom of in Fig. 5 shown and preferably first covered with a plastic film 16 down to obtain the tackiness of the layer 15.
  • a transition is, for example, in the transition from a sloping roof to the vertical walls of a fireplace before.
  • the rear portion of the film is then folded up along the arrow 14 and glued to the wall of a fireplace so that the band-shaped portion 12 covers the transition roof to fireplace.
  • the underlying area of the film is glued to the roof tiles and pressed into this. To ensure a firm hold, it is necessary to press the foil against the wall and the roof.
  • the waves 7 and 8 are slightly compressed, which is easy due to the structure of the film.
  • This in turn has the consequence that the pocket-like recesses are compressed.
  • the pocket-like recesses formed by the Fold 9 are located so that water can collect in this principle, the pressing of the film to the roof and the wall of the fireplace has the consequence that these pocket-like recesses are reduced so that hardly any water can get into these bags.
  • a test carried out over several years has shown that moisture damage does not occur under these circumstances. For this reason, it was possible to place the band-shaped region 12 parallel to the shafts 7 and 8, although it was first to be feared that water would then be in the pocket-like Recesses would accumulate disadvantageously. The practice has surprisingly shown that this is not the case for the reasons mentioned above.
  • a wave width of a few millimeters has been found, such as a width of 5 to 7 mm.
  • a wave, measured from the wave trough to the wave crest is expediently a few millimeters high, for example 1 to 3 mm.
  • Measured from Wellenberg to the neighboring wave mountain is an appropriate wavelength one to two centimeters.
  • the film is then expedient one to three tenths of a millimeter thick.
  • Suitable wavelengths and widths of the shafts 7 and 8 can be more accurately matched by the skilled person to the particular application.
  • the width of a wave is expediently of the order of half a wavelength. If a wavelength is e.g. 1.4 cm, such a shaft is preferably 0.7 cm wide. In this way it is ensured that there are no preferred directions in which such a film can be particularly easily deformed or pulled apart.
  • band-shaped region 1 2 instead of only one band-shaped region 1 2, it is also possible to provide a plurality of such band-shaped regions, which are free of undulating elevations. This is especially the case if the film is to be used in such a way that predictably multiple times kinked or bent. The various band-shaped regions 12 then run correspondingly.
