Method for providing the back of a web of carpet, artificial turf and the like with a coating. The web of carpet first passes through a preheating station, and after the carpet has been brought to temperature the web of carpet is fed to the coating station, the web of carpet first being compressed to a desired thickness. After that the web of carpet runs in the compressed state along the spray aperture of a spray head of a hot melt unit, where a hot melt such as a Vestoplast is applied as a coating to the back of the hot web of carpet. The compression of the web of carpet is then removed, and the web of carpet is then conveyed through an after-heating station. Both in the preheating station and in the after-heating station air is forced or sucked through the carpet transversely to the plane of the carpet. In the device for applying the coating the gap which determines how far the carpet is compressed is adjustable. |
