Abstract
Abstract Floor or wall covering is provided and comprises a decorative opaque surface layer bonded to a sheet backing obtained by comminuting, softening and resheeting a sheet material comprising a fibrous reinforcement, a layer of foamed vinyl resin and pigmented decoration. The fibrous reinforcement is normally of glass fibres and particulate inorganic filler is incorporated into the mass that is resheeted.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
77 words
A method of making a floor or wall covering comprising making a sheet material comprising fibrous reinforcement, a layer of foamed vinyl resin and pigmented decoration, wherein the fibrous reinforcement is selected from reinforcing fibres in the foamed layer and fibrous support beneath the foamed layer, comminuting this sheet into a mass of particles, softening the mass of particles, forming the softened mass into a substrate sheet and bonding a decorative opaque surface layer to the sheet.
Claim 2
Independent Claim
77 words
A method of making a floor or wall covering comprising making a sheet material comprising fibrous reinforcement, a layer of foamed vinyl resin and pigmented decoration, wherein the fibrous reinforcement is selected from reinforcing fibres in the foamed layer and fibrous support beneath the foamed layer, comminuting this sheet into a mass of particles, softening the mass of particles, forming the softened mass into a substrate sheet and bonding a decorative opaque surface layer to the sheet.
Claim 3
Dependent Claim
25 words
A method according to claim 1 in which the opaque surface layer comprises a layer of vinyl resin and pigmented decoration and a wear layer.
Claim 4
Dependent Claim
17 words
A method according to claim 1 in which additional polymeric material is incorporated in the softened mass.
Claim 5
Dependent Claim
27 words
A method according to claim 1 in which the fibres of the fibrous reinforcement comprise glass fibres and an inorganic filler is incorporated in the softened mass.
Claim 6
Dependent Claim
25 words
A method according to claim 1 in which the opaque surface layer comprises a layer of foamed vinyl resin and pigmented decoration and wear layer.
Claim 7
Dependent Claim
40 words
A method according to claim 5 in which the opaque surface layer is bonded on to the substrate sheet by a method comprising depositing on to the substrate sheet a layer of foamable vinyl resin composition and subsequently foaming this.
Claim 8
Dependent Claim
17 words
A method according to claim 6 in which the foamed layer possesses, after foaming, an embossed profile.
Claim 9
Dependent Claim
16 words
A method according to claim 6 in which, after foaming the foamed layer is mechanically embossed.
Claim 10
Dependent Claim
129 words
A method according to claim 1 comprising making a sheet material comprising glass fibre reinforcement, a layer of foamed vinyl resin and pigmented decoration and a wear layer over the foam layer wherein the glass fibre reinforcement is selected from glass reinforcing fibres in the foamed layer and a glass fibrous support beneath the foamed layer, comminuting this sheet into a mass of particles, softening the mass of particles, incorporating into the mass of particles 5 to 30% by weight of the mass of polymeric material and 20 to 150% by weight of the mass of inorganic filler, forming the softened mass into a substrate sheet, depositing a foamable vinyl resin composition on to the substrate sheet, applying pigmented decoration and a wear layer and foaming the foamable composition.
Claim 11
Dependent Claim
45 words
A method according to claim 9 in which the amount of glass fibre introduced to the mass as reinforcing fibres in the said sheet material and the amount of filler incorporated into the mass together totals from 30 to 75% by weight of the mass.
Claim 12
Dependent Claim
22 words
Floor or wall covering formed by the method of claim 1 comprising a decorative opaque surface layer bonded to a substrate sheet.
Claim 13
Dependent Claim
35 words
Covering according to claim 11 in which the sheet formed from the mass of particles includes also 5 to 30% by weight additional polymeric material and 30 to 75% by weight of inorganic particulate filler.
Claim 14
Dependent Claim
20 words
Covering according to claim 11 in which the decorative opaque surface layer is a layer of decorative pigmented vinyl material.
Claim 15
Dependent Claim
22 words
Covering according to claim 11 in which the decorative opaque surface layer comprises an embossed foamed vinyl layer carrying a pigmented decoration.
