ABSTRACT:
A novel carpet construction provides a secondary backing layer adhered to the primary backing layer in which the carpet pile is secured. The secondary backing layer incorporates a layer of downwardly depending loops which can serve as a resilient undersurface, in the manner of an underpad, and also to secure the laminated carpet structure to the floor. A hooked type construction used in combination with the subject carpet has a plurality of upwardly extending hooks to engage the looped layer of the carpet, and an adherent under surface, for making adhesive contact with the floor surface. The carpet construction can include a foam interlayer sandwiched between the primary and the secondary backing layers. The hooked tape can be laid as a perimeter attachment surface, or in intermediate locations also.
