Definitions
- the invention relates to a method for producing mineral fiber boards, in which mineral fibers wetted with a binder are deposited on a conveyor to form a mineral fiber layer in order to feed them to a continuous furnace, in which the mineral fiber layer in the ceiling is also pre-compressed during the conveying in front of the continuous furnace and then is folded in length by mutual bulging, the mineral fibers of the mineral fiber layer are matted and then the mineral fiber layer is compressed in such a way that it has a practically flat surface after curing.
- the invention further relates to a device which is suitable for performing the method. Finally, it refers to relevant mineral fiber boards.
- a comparable method is also known from DE-A-38 32 773, the longitudinal compression being carried out by bulging the mineral fiber layer in several stages arranged one behind the other until it enters the continuous furnace. This prevents the bulging from being carried out relatively abruptly in the inlet area of the continuous furnace after the mineral fiber layer has been pre-compressed.
- the method known from CH-C-620 861 can be used for a large number of different types of mineral fibers.
- a method of the type mentioned at the beginning and a device for carrying out the method are finally known from DE-A-16 35 620.
- the fiber layer is then felted over its entire thickness in order to fix the bulges.
- Another object is to develop a device for carrying out the method according to the invention. This is the subject of claim 1.
- Advantageous refinements of the method and the device are the subject of the respective dependent claims.
- the invention provides a mineral fiber board made by the disclosed method.
- the mineral fiber layer is deliberately matted in certain areas by maximizing the vertical component of the force in the region to be matted when a force can be exerted on the mineral fibers from the outside.
- the mineral fibers are aligned in this area, which means that the mineral fibers are entangled with one another.
- the matted areas prevent the longitudinally compressed structure from unfolding, so that the bending strength of known mineral fiber plates can be maintained and the tensile strength in the longitudinal direction does not suffer any losses.
- any desired density profile in these by specifying the corresponding areas. With continuous or step-by-step or step-by-step density transitions, this enables the best possible adjustments to be made to product specifications in terms of strength can be achieved.
- bulk densities in the order of 80 to 220 kg / m3 can be achieved, while in the non-matted areas of the mineral fiber board there is a bulk density in the range of 30 to 150 kg / m3.
- Maximizing the vertical component of the force can be achieved, for example, by inserting at least one needle or pin into the mineral fiber layer, the relative speed between the needle or pin and the mineral fibers being minimized in the area to be matted.
- the force transmission between the needle or pin and the mineral fibers, supported by the adhesive forces of the binder is particularly great.
- a device for producing mineral fiber boards in particular for carrying out the method according to claim 1 or claim 2, a conveyor for conveying a mineral fiber layer and a pre-press for thickness pre-compression of the mineral fiber layer, a device for longitudinally compressing the mineral fiber layer by mutual bulging, one downstream of the device for longitudinal compression Felting device and a continuous furnace further comprises a transfer belt device, the felting device being arranged directly upstream of the transfer belt device and the continuous furnace being immediately downstream of the transfer belt device.
- a device for the felting device which maximizes the vertical component of the force transmitted from the felting device to the mineral fibers of the mineral fiber layer.
- the device for the vertical component can be realized, for example, by means of a needle board machine with oscillating needles, which thus immerse to different depths in the areas of the mineral fiber layer to be matted in accordance with this oscillating movement, the speed of movement of the needles essentially being a sine function with minimal speed at the reversal points follows the oscillating movement.
- the needles are provided at least in sections with at least one beard projecting from the peripheral surface of the needle or, alternatively or in combination with it, at least one notch receding from the peripheral surface.
- a plurality of such beards or notches will be provided, which are spaced apart from one another in the longitudinal direction of the needle.
- These beards or the projections which are formed between adjacent notches take the fibers with them when the needle board is moved, so that the desired power transmission can take place in a particularly simple manner. This measure has an advantageous effect in combination with the "sinusoidal" movement of the needles themselves.
- Needles of different lengths can also be provided, which in turn are provided with beards or notches. It is thus achieved that in certain areas only the longer needles arranged further apart act, in others the entirety of the now closely adjacent needles, which causes a different degree of matting.
- the needle board machine can be designed to act only on one side of the mineral fiber layer. For most applications, however, it will be expedient if the needle board machine has two needle boards arranged opposite one another, which are each provided with a plurality of needles on the side facing the mineral fiber layer.
- the device for the vertical component of the force can also be formed by at least one rotating metal brush, the rotational speed of which can be selected.
- the brush pens look similar to the beards on the needles of the needle boards.
- the device is preferably used when it is intended to act on surface areas of the mineral fiber layer, the pin length or needle length of the brushes essentially corresponding to the layer thickness of the surface area of the mineral fiber layer to be matted and the closest distance of the rollers approximately to the thickness of the mineral fiber plate to be produced .
- the choice of device parameters can determine the extent to which matting is to take place, it being readily possible to adapt to the desired layer thickness of the end product.
- the felting device comprises both at least one brush roller and a needle board machine.
- the brush would have advantages in the continuous processing of the mineral fibers, but the needle intensity is too low here, so that repeated passes through the plates or a large number of brushes would be necessary for good results.
- needle board machines are used that provide better needling, although the more complex drive means that more equipment is required.
- the pre-press 4 consists of two rollers 26 and 27 driven in opposite directions with a diameter which is larger than that of the compression rollers used in a device 5 for longitudinal compression.
- the mineral fiber layer 3 emerging from the pre-press 4 is fed to this device 5 for longitudinal compression, compression elements being provided, for example the aforementioned rollers or conveyor belts, which are operated in the direction of a continuous furnace 7 with decreasing peripheral speed. This results in a gradual bulging of the mineral fiber layer, which leads to a folding of the layer, the folds being formed essentially transversely to the direction of transport of the mineral fiber layer 3.
- a felting device 8 Downstream of the device 5 for longitudinal compression is a felting device 8, which consists of two opposing rotating metal brushes 28, 29. These metal brushes 28, 29 extend as rollers over the entire width of the mineral fiber layer 3.
- a large number of pins or needles are attached to the roller surfaces, the pin length or needle length being essentially the same as the layer thickness of the surface area of the mineral fiber layer 3 to be matted.
- the closest distance between the outer surfaces of the rollers corresponds approximately to the thickness of the mineral fiber board to be produced.
- the pins or needles tear fibers preferentially from the bulges of the mineral fiber layer and matt the fibers of neighboring bulges. This not only ensures that the bulges are connected to one another, but at the same time creates a pre-smoothed surface of the mineral fiber layer.
- mineral fibers wetted with a binder are deposited on the conveyor 2. These fibers are fed to the pre-press 4, where they are aligned essentially in the conveying direction. A mineral fiber layer 3 is formed, the thickness of which is determined by the mutual spacing of the rollers 26, 27 of the pre-press 4.
- the now pre-compressed mineral fiber layer 3 is fed to a device 5 for longitudinal compression, by means of which the mineral fiber layer 3 is folded.
- the surface areas of the mineral fiber layer are torn open at a preselected depth, so that adjacent bulges of the mineral fiber layer are connected to one another by fibers that are largely isotropically oriented in this area.
- the surface areas homogenized in this way namely the top and bottom of the mineral fiber layer, are smoothed on the surface by a transfer belt device 6 from two opposing conveyor belts 24, 25 and fed to the continuous furnace 7 by hardening the mineral fiber layer now prepared according to the invention into a solid plate.
- FIG. 2 A further embodiment of the present invention is shown in FIG. 2.
- the device shown in this figure differs from that of FIG. 1 in the configuration of the felting device, while the others Device elements with which the device shown in Fig. 1 are structurally identical and functionally the same.
- the folded mineral fiber layer which was formed during the passage through the device for longitudinal compression, is now fed to a felting device 8, which consists of two needle boards 30, 31 lying opposite one another, which are lifted off or lowered onto the mineral fiber layer 3 with the aid of a suitable drive can.
- These needle boards 30, 31 have, on their side facing the mineral fiber layer 3, an arrangement of needles by means of which, depending on their configuration, a density distribution determined by the respective degree of matting can also be formed inside the mineral fiber layer.
- FIG. 3 shows a schematic representation of a first embodiment of a needle board 30 with a plurality of needles 32 directed towards the mineral fiber layer 3, of which only four are shown here.
- the lifting movement of the needle board 30 is indicated by the representation of four positions.
- Each needle 32 is provided with beards 33 projecting from the circumferential surface of the needle, which in the example shown here are arranged at an approximately constant distance from one another on the needle.
- the needle board 30 is operated in such a way that the vertical needle speed essentially follows a sine function which is superimposed on an oscillating change in immersion depth.
- the maximum stroke of the needle board 30 can be, for example, 60 mm.
- the upper reversal point of the lifting movement is placed so that the needle board 30 is extended from the mineral fiber layer 3, while it is fully or only half immersed in the respective mineral reversal points 3, so that either the entirety of the whiskers 33 acts or only approximately the Half of the whiskers 33 in the lower area of the needles 32.
- the sinusoidal speed curve when the needles 32 are immersed and retracted means that fibers are only carried along by the whiskers 33 in certain areas. Due to the high vertical speed in the central area, the beards 33 cannot take any fibers with them because of the overcompensated adhesive forces there. When approaching the lower reversal points, however, the needle speed is reduced to zero, so that the beards pick up 33 fibers and redirect the vertical direction.
- an arrangement of the needles 32 with beards 33 according to FIG. 4 can be selected.
- About half of the total number of needles 32, 34 is shortened, so that their effect on region A near the surface of the mineral fiber layer 3 is limited.
- the other half of the needles 34 acts both in the area A and in the adjoining area B.
- the area A is again heavily matted, the Area B matted to a lesser extent, whereby a clear gradation is achieved here.
- a multiple gradation of the degree of matting can also be achieved here.
- FIG. 5 shows a third exemplary embodiment of a needle board, in which the needle board 30 carries a plurality of needles 35, which are each provided with beards 33 only in their lower end section.
- the needles 35 or beards 33 act, again in combination with the sinusoidal movement speed, only in an area B lying away from the surface, while the area A close to the surface remains practically completely unaffected. As explained above, in area A the speed of the needles 35 is too high for fibers to be taken along.
- needle board 30 needle boards on both sides of the mineral fiber layer 3, as shown in FIG. 2, or a combination of differently designed needle boards, optionally in combination with metal brushes 28, 29, as also shown in FIG. 2, will be selected .
- the needle boards 30, 31, as can be seen in FIG. 2 are expediently followed by two opposing rotating metal brushes 28, 29 which correspond to those as have already been described in connection with FIG. 1.
- This felting device consisting of needle boards 30, 31 and metal brushes 28, 29 is in turn followed by a transfer belt device 6, which consists of two conveyor belts 24, 25 lying opposite one another and which smoothes the surfaces of the mineral fiber layer 3.
- FIG. 6 a shows a section of a mineral fiber plate 3 produced by the method according to the invention, in which the surface areas 36, 37 are treated. In the middle region 38 the fold structure created by the longitudinal compression is preserved, while in the surface regions 36, 37 this orientation of the fibers is raised, so that an essentially homogeneous, isotropic fiber layer has formed there.
- FIG. 6 (b) shows a section of a mineral fiber plate which has been produced using the needle board according to FIG. 5. Here, the central area 39 is homogenized, while the areas near the surface show their uninfluenced fold structure.
- the stroke frequency of the needle board i.e. the frequency for the sine function to choose from the range of 5 to 25 Hz.
