Abstract
Abstract The invention relates to a floor and/or wall covering, its manufacturing process, as well as to an installation for performing this process. It specifically relates to a non-woven floor and/or wall covering having at least one layer of parallel juxtaposed textile threads and a supporting layer to which are individually fixed various textile threads. Particular applications of the invention are to all types of floor and wall coverings and to furnishing fabrics.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 words
A floor and/or wall covering of the non-woven type comprising at least one layer of parallel juxtaposed textile threads, as well as a supporting layer to which are individually fixed the said textile threads formed from a plurality of more or less twisted fibres, wherein the textile threads have a diameter of at least 1 mm and said twisted fibres have a diameter of at most 0.1 mm, wherein a small portion of the fibres of each textile thread is fixed to the supporting layer by low density needling without destroying the continuity and the initial appearance of each textile thread, wherein each of the fixing fibres have two end portions disposed more or less parallel to said supporting layer and a middle part extending transversely to said supporting layer, one of said end portions being frictionnally attached to the other fibres of the corresponding textile thread and the other end portion being embedded in a coating applied to the back of said supporting layer.
Claim 2
Dependent Claim
165 words
A floor and/or wall covering of the non-woven type comprising at least one layer of parallel juxtaposed textile threads, as well as a supporting layer to which are individually fixed the said textile threads formed from a plurality of more or less twisted fibres, wherein the textile threads have a diameter of at least 1 mm and said twisted fibres have a diameter of at most 0.1 mm, wherein a small portion of the fibres of each textile thread is fixed to the supporting layer by low density needling without destroying the continuity and the initial appearance of each textile thread, wherein each of the fixing fibres have two end portions disposed more or less parallel to said supporting layer and a middle part extending transversely to said supporting layer, one of said end portions being frictionnally attached to the other fibres of the corresponding textile thread and the other end portion being embedded in a coating applied to the back of said supporting layer.
Claim 3
Dependent Claim
37 words
A floor and/or wall covering according to claim 1, wherein the threads of the layer of threads have different diameters and are grouped so that threads of one diameter alternate with groups of threads of different diameters.
Claim 4
Dependent Claim
24 words
A floor and/or wall covering according to claim 1, wherein the threads of the layer of threads comprise groups of threads of different types.
Claim 5
Dependent Claim
22 words
A floor and/or wall covering according to claim 1, wherein the threads of the layer of threads comprise threads of different configurations.
Claim 6
Dependent Claim
42 words
A floor and/or wall covering according to claim 1, wherein the textile threads at least partly comprise chenilles whose cut threads forming the weft are needled to the supporting layer in the binding area with the chenille binding threads forming the warp.
Claim 7
Dependent Claim
56 words
A floor and/or wall covering according to claim 1, wherein it comprises two layers of threads the second at least partly covering the first layer of threads, and wherein the threads of the second layer are connected to the supporting layer by connecting fibres from the threads and embedded in the said supporting layer by needling.
Claim 8
Dependent Claim
29 words
A floor and/or wall covering according to claim 6, wherein the threads of the second layer of threads are arranged on the first layer of threads in spaced groups.
Claim 9
Dependent Claim
28 words
A floor and/or wall covering according to claim 6, wherein the threads of the second layer of threads extend parallel to those of the first layer of threads.
Claim 10
Dependent Claim
28 words
A floor and/or wall covering according to claim 6, wherein the threads of the second layer of threads extend transversely to those of the first layer of threads.
Claim 11
Dependent Claim
25 words
A floor and/or wall covering according to claim 6, wherein the threads of the second layer of threads are fixed to a provisional supporting strip.
Claim 12
Dependent Claim
107 words
A manufacturing process for a floor and/or wall covering according to claim 1, wherein the threads of the layer of threads are applied to the supporting layer by a relatively low density needling operation, so that a small portion of the fibres of each textile thread has one of its end portions extending through and beyond said supporting layer and the other end portion still remaining within the fibre-assembling forming said textile thread and wherein the fibre end portions extending beyond said supporting layer are bent parallel to said layer and are recovered and embedded in a coating applied to the back side of said supporting layer.
Claim 13
Dependent Claim
33 words
A manufacturing process according to claim 11, wherein the supporting layer comprises a shrinkable textile fabric which undergoes a shrinking treatment after fixing the threads of the layer of threads thereto by needling.
