  • Patent number: 4751130
    Abstract: Floor covering, such as carpets (40) or other covering materials for residential and general furnishing, are fixed to a floor or other surface (10) by means of an applied bonding layer (42).Embedded into the bonding layer are adhesive particles which are made chemically passive and the cohesive forces of which are greater in the thermoplastic state than their adhesive forces and which are converted, only after the carpet has been laid and adjusted in position, from their non-adhesive state into a malleable tacky phase of the layer as a result of the effect of temperature, after which a firm bond is produced in a cooling phase as a result of the lowering of this temperature.Alternatively, the bonding layer may be provided by a separate interlayer.
