Abstract
The invention relates to a method for coating grey goods for carpeting (1) comprising an upper layer (21) containing filaments, according to which a thermoplastic material (8) is applied to the upper layer (21) of the underside of the carpet, thus bonding the filaments in the grey goods (1). The invention also relates to a carpet comprising an upper layer of filaments, in which a thermoplastic material (8), which bonds the filaments in the carpet, is applied to the upper layer (21) of the underside of the carpet. In addition, the invention relates to a coating device for coating carpets comprising an upper layer (21) of filaments, said device being provided with transport elements for transporting the carpet (1) along the coating device. The device is also equipped with an applicator for applying the thermoplastic material (8) to the underside of the upper layer (21) of the grey goods that are transported past said applicator.
