Abstract
Abstract In a floor covering a layer of resilient material is bonded to the bottom of an upper layer and reinforcement is provided associated with or adjacent the bottom surface of the resilient material, whereby the floor covering can be secured to a floor by an adhesive, but can subsequently be peeled off the floor. An important embodiment is a carpet having a foam rubber-like underlay bonded to the carpet back and a mesh of plastic material positioned on the carpet back. Generally, the covering may be laid on a floor by laying the reinforcement mesh or the like on a floor, spraying or otherwise distributing adhesive material and the laying of the covering to secure it by the adhesive.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
159 words
A floor covering comprising: a first layer having a surface for carrying traffic; a second layer secured to the first layer and providing a resilient foam backing which is to be laid on a floor and secured thereto by adhesive; and a knitted open mesh of material having a multiplicity of openings therein accounting for a large proportion of the area of the mesh and located on the side of said second layer remote from said first layer for contacting the floor on which the floor covering is to be laid, whereby the application of an adhesive to the floor permits portions of said resilient foam backing to adhere to the floor through said multiplicity of openings in the open mesh and by pulling on the open mesh said first and second layers which are secured together, the floor covering may be peeled subsequently off the floor without leaving gross quantities of said foam backing adhering to the floor.
Claim 2
Dependent Claim
159 words
A floor covering comprising: a first layer having a surface for carrying traffic; a second layer secured to the first layer and providing a resilient foam backing which is to be laid on a floor and secured thereto by adhesive; and a knitted open mesh of material having a multiplicity of openings therein accounting for a large proportion of the area of the mesh and located on the side of said second layer remote from said first layer for contacting the floor on which the floor covering is to be laid, whereby the application of an adhesive to the floor permits portions of said resilient foam backing to adhere to the floor through said multiplicity of openings in the open mesh and by pulling on the open mesh said first and second layers which are secured together, the floor covering may be peeled subsequently off the floor without leaving gross quantities of said foam backing adhering to the floor.
Claim 3
Dependent Claim
41 words
A floor covering as claimed in claim 1, wherein said first and second layers are in a roll and said open mesh is in a separate roll, said rolls being adapted to be unrolled over the floor in a laying operation.
Claim 4
Dependent Claim
20 words
A floor covering as claimed in claim 1, wherein said open mesh is a knitted polypropylene mesh of flat filament.
Claim 5
Dependent Claim
50 words
A floor covering as claimed in claim 3, wherein the area of each of said multiplicity of openings does not exceed an area of about 50 square millimeters and the proportion of the mesh taken up by said multiplicity of openings is a very large majority of the total area.
Claim 6
Dependent Claim
79 words
A floor covering comprising: a tufted carpet having tufts secured in a primary backing and a resilient foam underlay bonded to said primary backing; and a separate open mesh of knitted polypropylene for location between said foam underlay and a floor whereby adhesive applied to the floor can secure the underlay through openings in the mesh to the floor but the carpet can be peeled off by a peeling action involving the application of pressure to the open mesh.
Claim 7
Dependent Claim
79 words
A floor covering comprising: a tufted carpet having tufts secured in a primary backing and a resilient foam underlay bonded to said primary backing; and a separate open mesh of knitted polypropylene for location between said foam underlay and a floor whereby adhesive applied to the floor can secure the underlay through openings in the mesh to the floor but the carpet can be peeled off by a peeling action involving the application of pressure to the open mesh.
Claim 8
Independent Claim
105 words
A method of laying a floor covering comprising the steps of: laying a knitted open mesh of material having a multiplicity of openings therein accounting for a large proportion of the area of the mesh on the floor to be covered; applying adhesive to the floor and laying a first layer having a surface for carrying traffic secured to a second layer providing a resilient foam backing which is to be laid on a floor over the open mesh with the side of the second layer remote from the first layer adhering to the floor in its portion aligned with openings in the open mesh.
Claim 9
Independent Claim
105 words
A method of laying a floor covering comprising the steps of: laying a knitted open mesh of material having a multiplicity of openings therein accounting for a large proportion of the area of the mesh on the floor to be covered; applying adhesive to the floor and laying a first layer having a surface for carrying traffic secured to a second layer providing a resilient foam backing which is to be laid on a floor over the open mesh with the side of the second layer remote from the first layer adhering to the floor in its portion aligned with openings in the open mesh.
Claim 10
Dependent Claim
42 words
A method as claimed in claim 6, wherein said adhesive is a transfer contact adhesive for securely retaining the floor covering in position during use and permitting the floor covering to be peeled off the floor at a subsequent point in time.
Claim 11
Dependent Claim
53 words
A method as claimed in claim 7, wherein prior to applying said adhesive, the first and second layers which are secured together are laid in position and cut to size as necessary and then folded back, the method then comprising laying the open mesh in position and spraying said adhesive over the floor.
