As it turned out 1 results, a Gegenzugimprägnat invention consists of an impregnated paper, a so-called Gegenzugpapier 1 , On the one side a sound-insulating material layer 2 by means of an adhesive coating 3 is applied. The return paper 1 advantageously consists of a regenerated paper based on noble pulps, with a base paper grammage of 70 to 140 g / m ^{2 is} appropriate. The final weight after impregnation with, for example, melamine resin is preferably 170 to 320 g / m ² . The amount of resin used, and thus the resulting final weight, as well as the base paper used are highly dependent on the type of overlay on the top of a laminate bottom plate for which the countertransfer paper 1 comes to use. The resin is a harminoplast resin consisting of urea and / or melamine resins.

The sound-absorbing material layer 2 preferably consists of a foamed plastic material. However, it is also possible to use felt, cork or a rubber material or mixtures thereof. Preferably, a polyurethane foam is used, which consists in particular of a mixture of polyurethane recycled foam, polyurethane composite foam and binder. The density is preferably 200 to 400 kg / m ² , in particular 300 kg / m ² . The ignition temperature is preferably above 400 ° C and the decomposition temperature is greater than 180 ° C. The polyurethane foam used in the invention consists of a preferably 3 mm thick polyurethane foam film.

As an adhesive for the production of the adhesive coating 3 For example, it is preferable to use a hot-melt, pressure-sensitive adhesive or a copolymer-based dispersion adhesive. The latter preferably has a viscosity (Brookfield RV 23 ° C) of about 7000 mPas at a solids content of preferably 69% and a pH of about 5.5. The adhesive used according to the invention on the one hand ensures a good connection between the impregnated Gegenzugpapier 1 and the sound-absorbing material layer 2 and withstands the pressing conditions in the production of a laminate floor slab according to the invention.

In 2 is one using the Gegenzugimprägnats invention according to 1 produced laminate bottom plate according to the invention 4 , in particular a floor laminate, shown. This laminate floor plate 4 consists of a carrier plate 5 , on the top of which a coating - suitably made of an impregnated decorative paper 6 - Is arranged on its top a coating of an overlay paper 7 having. Both decorative and overlay paper 6 . 7 are resin-impregnated materials. On its underside has the support plate 5 an inventive Gegenzugimprägnat, as in 1 described on. The sound-insulating material layer forms 2 the lowest layer of the laminate bottom plate according to the invention 4 , this material layer 2 has a condition influenced by the production-related compression.

The production of the laminate floor panel according to the invention 4 takes place in particular in a short-cycle or double-belt press, in which the overlay paper 7 with the printed and impregnated decorative paper 6 as well as the carrier plate 5 and the Gegenzugimprägnat invention be pressed using special press plates or bands under a pressure of 20 to 40 bar and at a pressing temperature of 160 to 200 ° C with a pressing time of 10 to 30 seconds. In this case, the pressure is such that the Gegenzugimprägnat invention with its sound-insulating material layer 2 is arranged such that it bears against the respective press plate, so that the sound-insulating material layer 2 at the same time serves as a press pad. Accordingly, the Gegenzugimprägnat invention with the impregnated Gegenzugpapier 1 inserted at the top so in the press line, that thereon the carrier plate 4 can be stored. On the carrier plate, the impregnated decorative paper before pressing 6 and on this the overlay paper 7 hung up. The pressing process is set such that the finished laminate bottom plate 4 Ensures a sufficient flatness during later installation.

The laminate floor panel according to the invention is characterized by an improved sound insulation compared to known panels. This improved impact sound insulation results from the following measurements:
On two variants of a laminate floor construction, the room acoustic properties were determined and the results compared to the so-called ihd reference floor construction - DPL laminate floor (thickness: 7.2 mm), PUR foam film (density: 22 kg / m ³ , thickness 3.0 mm ), PE film (usual vapor barrier, thickness 0.2 mm) - comparative evaluated. The impact sound behavior when walking was determined according to the ihd works standard 431:
The experiment was carried out on the following laminate floor structures: Version 1: "Standard": DPL laminate (panel dimensions: 194 × 1290 × 7 mm ³ ), PE foam sheet (thickness: 3 mm), underlayed, PE film as moisture barrier; Variant 2: DPL laminate according to the invention (panel dimensions 194 × 1290 × 7.5 mm ³⁾ PUR foam film (thickness: 3 mm), PE film as a moisture barrier.

The exam takes place in a measuring room in which a concrete slab of 2.40 m long, 2 m wide and 12 cm thick is installed in the middle. There were each 15 measurements of the footfall, the uniform walking the laid out floor structures by a subject with heel shoes (hard rubber coating), carried out. For the characterization of the room acoustic properties, the Walking sound of the first step of the subject on the walking distance used. As measured variables for the resulting Climbing became the A-weighted overall sound pressure level above the frequency range (25 Hz to 12500 Hz) in dB (A) and the psychoacoustic loudness used in Sone, which according to the ihd factory standard 431 version 04/2003 were determined.

In Tables 1 and 2 are the determined characteristics of the floor structures comparatively contrasted. The characteristic values became after deletion of the largest and smallest measured value (Outlier correction) according to ihd factory standard 431 Version 04/2003 determined.

The Result is as the respective difference of the total sound pressure level or the loudness of the tested variant compared to the Reference structure.

The improvement measure of the total sound pressure level is to be evaluated as follows:
+0.5 dB (A) improvement only noticeable under good acoustic conditions
+1.0 dB (A) -recognizable threshold for improvement
+3.0 dB (A) half of the signal energy
+6.0 dB (A) half-tone sound pressure
+10 dB (A) -Half the subjective volume

The change in the linear parameter Loudness (N) is determined with respect to the reference as a percentage as follows:
Percent change:

Of the determined parameter gives the percentage increase (negative value) / reduction (positive value) of the loudness sensation.

Table 1: A-weighted overall sound pressure level

Table 2: Loudness

The Variant 1 "standard" emitted walking noise nearly as strong as the ihd reference floor construction.

The Variant 2 contrasted by a reduction the emitted sound energy. The audibly lower sound emission on the occasion of the commissioning of the variant 2 opposite the variant 1 shows itself in the form of a smaller A-weighted overall sound pressure level and a smaller loudness value (see Tab. 1 and Tab. 2).

It this results in an improvement of the sound level above the standard of approx. +6 dB (A) or a halving of the sound pressure according to ihd factory standard version 04/2003.

Furthermore, the laminate floor panel according to the invention is characterized 4 by economic and ecological advantages, since, for example, less formaldehyde content is present. In addition, a delivery in customer format with processing guarantee is possible. The laminate floor panel according to the invention 4 can be cut into planks of the desired dimensions after the pressing and maturing process. These already provided with the insulating layer boards can be milled with tongue and groove and packed ready for sale. As material of the carrier plate 5 HDF, MDF, chip or regenerate plates or the like can be used.

Based 3 becomes a device according to the invention 10 for the preparation of a Gegenzugimprägnates invention. How out 3 it can be seen, there is this laminating device according to the invention 10 from a support device 11 made of a frame 12 for attachment to a bottom plate and a flat support surface 13 consists. At one end of the support surface 13 is a unwinding device 14 arranged. This unwinding device 14 has a bearing receptacle with a bearing axis 15 on, on an insulating roll 16 is arranged, and from the one in the withdrawal direction X on the insulation roll 16 rolled insulation web 17 for forming the sound-insulating material layer 2 of the Gegenzuglmprägnats can be deducted. The unwinding device 14 also has an immediately in the withdrawal direction X behind the insulation roll 16 in the frame 12 mounted deflection pulley 18 for the insulation web 17 on.

In withdrawal direction X behind the pulley 18 is on the frame 12 a sheeter 19 attached. This consists for example of a above the insulation web 17 or the support surface 13 transversely, in particular perpendicular, to the withdrawal direction X extending terminal block 20 , on which a circular knife 20a movably guided.

In the illustrated embodiment, four equally spaced applicator nozzles 24 for the adhesive coating 3 present, with which four traces of glue 25 on the insulation web 17 can be applied. However, it is also within the scope of the invention to have more or fewer application nozzles 24 provided. The coating weight is preferably on average 10 g / mm ² .

Furthermore, the support device 11 a gripping device 27 on, with the of the insulation roll 16 to be deducted insulation web 17 taken and in the direction of the withdrawal direction X over the support surface 13 can be pulled until the desired Ablängmaß for the insulation web 17 is reached. The gripping device 27 consists of a transverse, in particular perpendicular, extending to the withdrawal direction X bars 28 , on the gripper 27 In the example shown, three equally spaced grippers 29 are attached. These grippers 29 are electrically or pneumatically actuated and are designed such that the free end of the insulating material web 17 safely gripped and fixed and can be released again after cutting to length. The bar 28 is at its ends on guide rails 30 mounted on a drive device, in particular a linear drive device. This linear drive device is formed in a known manner and therefore not described in detail. For easy removal of the insulating material web 17 from the insulation roll 16 is a the bearing axis 15 driving electric motor 26 provided, whereby the deduction of the insulating material web 17 by means of the gripping device 27 can be supported, which is why the speed of the extraction movement of the gripper 29 in withdrawal direction X by means of the linear drive and the drive speed of the electric motor 26 are advantageously matched to one another in terms of control.

The support device 11 consists of a lifting, storage and transport device 31 , with on one side next to the support surface 13 to a paper stack 32 Stacked impregnated paper blanks 33 Coming to the tracing paper (impregnated paper 1 ) according to 1 correspond, raised, transverse, in particular perpendicular, transported to the withdrawal direction X and then from a position above the support surface 13 can be lowered again.

With another transport device 34 can on the support surface 13 manufactured, blanks 35 Inventive Gegenzugimprägnate, as in 1 described, from the support surface 13 raised, transversely, in particular perpendicular, transposed to the withdrawal direction X and into a stack 36 to be deposited, to the paper stack 32 parallel to the support surface 13 - Side of this - is arranged opposite.

The two transport devices 31 . 34 are in two transverse, in particular perpendicular, to the withdrawal direction X and parallel to each other arranged portal carriers 37 at the horizontal support sections 38 slidably guided and independently movable over a conventional linear drive or the like.

The transport device 31 consists of a transport frame 39 , which has pneumatic or hydraulic piston-cylinder units 40 lowerable and liftable suction cups 41 and pressing strips 42 are attached. The suckers 41 and pressing strips 42 lie with their contact surfaces for the paper blanks 33 in the same plane parallel to the stacked paper blanks 33 runs.

In the illustrated embodiment, three parallel rows of four piston-cylinder units 40 and three suckers 41 available. Here are the suckers 41 each row at a particular perpendicular to the withdrawal direction X extending carrier strip 43 attached. In addition, four are parallel to each other and perpendicular to the carrier bars 43 extending pressure strips 42 intended. In each case one of the pressing strips 42 is at the free ends of the carrier bars 43 arranged, and the other two Andrückleisten 42 are arranged such that the distance to the adjacent Andrückleisten 42 a unit 40 and their mutual distance is the same.

The transport device 34 for the Gegenzugimprägnat-blanks invention 35 has substantially the same structure with respect to the arrangement and design of the transport frame and the attachment of suckers 44 on piston-cylinder arrangements 45 , In that regard, like parts are given the same reference numerals. However, here are the suckers 44 directly transversely at the free end of the piston rod 46 a piston-cylinder arrangement 45 attached. In addition, no pressing strips are required. With the suckers 41 . 44 the suction effect is achieved by generating negative pressure. In a preferred embodiment, the paper blanks 33 and the counter impregnate blanks 35 a length of 2400 to 5700 mm and a width of 1260 to 2080 mm.

The operation of the laminating device according to the invention 10 is as follows. Once the paper stack 32 from paper blanks 33 and the insulating roll 16 are provided, the gripping device 27 directly to the cross cutter 19 moved up to the free end of the insulation roll 16 by the required length to the cross cutter 19 withdrawn insulation web 17 to grab and fix. The width of the paper blank 33 is at the width of the insulating material web 17 customized.

Once the insulation sheet 17 from the grapples 29 is gripped, is the insulating material web 17 by moving the gripping device 27 moved by means of the linear drive in the withdrawal direction X and thereby the insulation web 17 over the support surface 13 Pulled until the desired length of on the support surface 13 lying train 17 is reached. During the peeling process are over the applicator nozzles 24 the glue marks 25 on the insulation web 17 applied. Upon completion of the peeling process, the adhesive job is terminated.

After this is the terminal strip 20 of the cross cutter 19 lowered and the insulation web 17 fixed and with the circular knife 20a cut to length.

By means of the transport device 31 now becomes a paper blank 33 from the paper stack 32 lifted. For this purpose, the transport device 31 over the paper stack 32 positioned and the suckers 41 be with the pressing strips 42 lowered until it is on the top paper blank 33 rest. Now in the suckers 41 creates a negative pressure and thus the paper blank 33 under attachment to the Andrückleisten 42 fixed. In this state, the suckers 41 and the pressure bars 42 lifted and the transport device 31 proceed as far as they are just above the insulating material web 17 is positioned.

From this position, the paper blank 33 on the insulation web 17 lowered and stored on this, using the Andrückleisten 42 the paper blank 33 against the insulation web 17 is pressed. Because the pressure strips 42 are arranged so that they are above the glue marks 25 run, there is the maximum contact pressure where the adhesive application is present. As a result, a good and secure adhesive bond between the insulation web 17 and the paper blank 33 reached.

Now, the negative pressure in the suckers 41 lifted, so this with the pressure bars 42 raised and the transport device 31 again over the paper stack 32 can be moved.

Thereafter, the transport device 34 that up to that point above the counter impregnate stack 36 was positioned over the coated insulation web 17 procedure and aligned exactly over this. From this position, the suckers 44 on the surface of the coated insulation web 17 lowered.

In the plant position the suckers 44 is generated in this negative pressure and thus the coated insulation web 17 on the suckers 44 fixed. It will now be the gripper 29 opened and withdrawn and the terminal block 20 raised so that the cut and coated insulation sheet 17 that the Gegenzugimprägnat-blank according to the invention 35 forms, raised and over the pile 36 can be moved. From this position, the Gegenzugimprägnat-cut 35 lowered and in the lowered position, the negative pressure in the suckers 44 canceled. Thereafter, the method described above starts again.
