  • Patent number: 5902663
    Abstract: A low-stretch and dimensionally stable floor covering (1) comprising polymer-containing pile material (2) which is retained to a polymer-containing primary backing (3), to the back of which an underlying secondary backing layer (5) is retained by means of an interleafing adhesive layer (4). The secondary backing layer (5) comprises a needled fibre structure of thermoplastic, polymer-containing, continuous or staple fibres being inter-fixated by heating. The adhesive layer (4) comprises an organic, polymer-containing binder which is activated by heat application. According to the invention, at least the secondary backing layer and/or the binder layer comprise a substantially re-usable material. After being formed, the carpet is wound onto so-called broadloom rollers and can, if desired, be cut partially into carpet tiles. Thus, carpet tiles and broadloom carpets can be manufactured in the same production process.
