Abstract
A floor covering produced by coating and including a thermoplastic-based structure, in particular plasticized PVC, reinforced with a textile reinforcement, optionally combined with a foam backing. The visible surface consists of a surface coating providing decoration and wear resistance to the product. The back surface, designed to be in contact with the floor, consists of a textile web, the bonding between the textile structure and the supporting back surface being produced by means of an additional plastisol layer, which penetrates over a minor part of the thickness of the textile structure and which, after gelling, bonds the textile to the thermoplastic substrate back surface.
