Foam backed carpet with adhesive release surface and method of installing same

A floor covering comprising a carpet having pile yarns forming a fibrous face and a primary backing to which the pile yarns are secured, a secondary backing engaging said primary backing, said secondary backing being a plastisol composition containing polymers or copolymers of vinyl compounds, a transparent layer of pressure sensitive adhesive on said secondary backing for releasably securing the floor covering to an underlying floor, said adhesive being an oleophobic adhesive and having high shear strength for preventing slippage between the floor covering and an underlying floor and having low tensile strength to facilitate removal and replacement of the floor covering by permitting peeling of the carpet from the floor and wherein the affinity and cohesiveness of the oleophobic adhesive for the secondary backing is greater than that for an underlying floor to permit removal and replacement of the floor covering without an appreciable amount of adhesive being removed from the secondary backing and left on the floor, a transparent and flexible release cover formed from linear low density polyethylene releasably secured to said layer of pressure sensitive adhesive to protect and maintain the tackiness of the adhesive layer before laying of the floor covering on an underlying floor, and printed arrows on said secondary backing corresponding to a predetermined direction of the lie of the pile yarns of the carpet, and wherein said printed arrows are readily visible through said transparent layer of pressure sensitive adhesive and said transparent release cover so as to allow said printed arrows to be readily visible to facilitate orientation of various sections of the floor covering in common direction during installation so that the lie of the pile yarns of all of the sections is oriented in a common direction.

A method of installing a convolutely wound carpet having upstanding pile yarns secured to a primary backing with a secondary backing engaging the primary backing and wherein a transparent layer of pressure sensitive adhesive is present on the secondary backing, and wherein a release cover is releasably secured to the layer of pressure sensitive adhesive with the release cover having at least one tear line defined by a plurality of spaced apart perforations, and wherein the secondary backing has printed arrows thereon and readily visible through the release cover with the printed arrows corresponding to a predetermined direction of the lie of the pile yarns of the carpet, said method comprising the steps of (1) unrolling the carpet from the convolutely wound roll with the pile yarns facing downwardly, (2) cutting the downwardly facing unrolled carpet to form at least one cut length of carpet, (3) rupturing the release cover along the tear line and removing a portion of the release cover along one side of the ruptured tear line to expose the underlying layer of pressure sensitive adhesive on the secondary backing of the cut length of carpet, (4) positioning the cut length of carpet with the exposed adhesive layer against the floor to releasably secure the carpet to the floor, (5) removing the release cover from the remainder portion of the cut length of carpet, and (6) positioning the pressure sensitive adhesive layer of the remainder portion against the floor for thus securing the remainder of the cut length of carpet to the floor.
