Abstract
Laminated floorboards with sound damping in a less complicated manner. For this purpose, a compensating element, is provided in which an impregnated paper is joined to an insulating underlay. By means of the use of the compensating element in a laminated floorboard, in which the insulating underlay is used as a sound-damping material layer, in particular using an adhesive coating between paper and underlay, a halving of the sound pressure as compared with a standardized reference floor construction can be demonstrated in a footfall test. A series of process engineering, environmentally friendly and logistical advantages are associated with the use of the process and apparatuses according to the invention for production of compensating element and laminated floorboard, such as the omission of specific fabrication steps, a reduced use of formaldehyde and the ability to use simplified transport apparatuses.

- 1. A compensating element, in the form of an impregnated backing, for laminated floorboards comprising an impregnated paper, wherein the impregnated paper is joined to an insulating layer.
- 15. A laminated floorboard, in the form of a flooring laminate, comprising a supporting board which is coated on an upper side and is provided on an underside with a compensating element, in the form of an impregnated backing, wherein the compensating element, having an impregnated paper joined with an insulating layer in the form of a sound-damping layer joined by means of an adhesive coating, the compensating element is joined to the supporting board, the insulating layer forming the lowest layer of the composite.
- 19. A process for production of a compensating element, in particular an impregnated backing, wherein impregnated paper brought to a predefined dimensioned in paper blanks is stacked to form a paper stack, in each case a paper blank is lifted off the stack upper side and its deposited on a web of insulating material matched to the dimensions of the paper blank, the side of the web of insulating material that faces the paper to be deposited being provided with an adhesive layer before the deposition of the paper blank.
- 26. The process for production of a compensating element, in particular an impregnated backing, wherein the impregnated backing paper and an insulating underlay in the form of a sound-damping material layer, are in each case pulled off rolls in the form of webs and are subsequently pressed against each other in an arrangement lying one above the other, before the pressing the adhesive coating being applied to the insulating underlay, in particular the sound-damping material layer, on its side facing the backing paper web.
- 28. An apparatus for production of a compensating element for laminated floorboards, which comprises a supporting apparatus which has a supporting surface for a web of insulating material and on which at one end there is arranged an unwinding device for unwinding the web of insulating material from a roll of insulating material, by a crosscutter arranged after the unwinding device in the haul-off direction (X), a gripping device which can be displaced in and counter to the haul-off direction (X) along the supporting apparatus for the web of insulating material, and at least one lifting, depositing and transport apparatus arranged above the supporting surface for the transport of an impregnated paper blank and/or a compensating element blank transversely with respect to the haul-off direction (X).
- 40. A process for production of at laminated floorboard, wherein in order to obtain a compensating element, in the form of an impregnated backing a compensating film, in the form of impregnated paper is fixed to the insulating underlay and, after that, the composite formed in this way is laid on aids, then a/the supporting board as a core consisting of wooden material, a decorative layer preferably formed by a/the decorative paper, in particular impregnated with melamine resin, and the overlay are laid successively on the composite and, finally, the whole formed by these aforementioned layers is gripped, placed in a pressing apparatus and pressed.
