Claims

1. A method for the production of lightweight building boards comprising at least one outer layer and a core layer adhesively bonded to this, the adhesive being applied to at least one outer layer, wherein the application of the adhesive is effected by means of one or more rotating disk(s) which is or are mounted horizontally or with a the slight deviation of up to 15° from the horizontal, preferably parallel to the outer layer.
2. The method according to claim 1, wherein the rotating flat disk is in the form of a circular flat disk.
3. The method according to claim 1, wherein the rotating flat disk is in the form of a planar disk having borders ascending in a cascade-like manner.
4. The method according to claim 1, wherein the rotating flat disk is in the form of an ellipse.
5. The method according to claim 1, wherein the rotating flat disk is in the form of a planar, at least four-pointed planar star.
6. The method according to claim 1, wherein the rotating flat disk is in the form of an at least four-pointed star with the points curved upward.
7. The method according to claim 1, wherein the rotating flat disk has four or five points in the embodiment as a star.
8. The method according to claim 1, wherein the rotating disk in the form of a planar four- or five-pointed star has no straight lines and only rounded corners.
9. The method according to claim 1, wherein the rotating disk in the form of a planar four- or five-pointed star is in the form of a four- or five-pointed star with the points curved upward.
10. The method according to claim 1, wherein the rotating disk in the form of a planar disk having borders ascending in a cascade-like manner has outlet orifices in the form of holes or slots.
11. The method according to claim 1, wherein at least two rotating disks arranged one on top of the other are used.
12. The method according to claim 1, wherein a planar disk having borders ascending in a cascade-like manner, a plurality of disks mounted one on top of the other, an ellipse or a planar four- or five-pointed star is used as the rotating disk for applying the adhesive to the lower and/or upper outer layer a) and/or the lower and/or upper side of the core layer b).
13. The method according to claim 1, wherein the adhesive used is an isocyanate-based adhesive.
14. The method according to claim 1, wherein particleboards, MDF boards, OSB boards, plastic boards or metal plates are used as outer layers.
15. The method according to claim 1, wherein honeycomb, folded or plug-type structures comprising paper, board, wood or light metal are used as core layers.
16. The method according to claim 1, wherein light wood-based boards, preferably having a density of from 80 to 400 kg/m 3, are used as core layers.
17. An apparatus for the production of lightweight building boards by adhesive bonding of at least one outer layer to a core layer, wherein, for the application of the adhesive to the outer layer, said apparatus comprises one or more rotating disk(s) which are mounted one on top of the other and horizontally or with a slight deviation of up to 150 from the horizontal, preferably parallel to the outer layer.
