Abstract

A tufted carpet comprising a secondary backing which defines a volume being a parallelepiped having three pair of parallel faces, a first pair of parallel faces defining a upper surface of the secondary backing and a lower face of the tufted carpet, at least a second pair of parallel faces being inclined with respect to the first pair of parallel faces under an angle α 1 less than 90°, preferably in the range of 10 to 87°, the angle being the smallest angle measured between the planes defining the first pair of parallel faces and second pair of parallel faces.

First claim

The invention claimed is:

1. A tufted carpet tile having three pairs of faces comprising:
a first pair of generally parallel faces comprising a top face of carpet tufts and a bottom face of a secondary backing;
a second pair of faces consisting of a first edge face and a second edge face being inclined with respect to the first pair of generally parallel faces;
a third pair of faces adjacent to the first pair of generally parallel faces and adjacent to the second pair of faces;
wherein a first edge angle between the first pair of generally parallel faces and the first edge face is different than a second edge angle between the first pair of generally parallel faces and the second edge face; and
wherein each of the first and second edge angles are the smallest angles measured between the planes defining the first pair of generally parallel faces and each of the edge faces.

2. The tufted carpet tile of claim 1 , wherein the first and second edge angles are between about 10° and about 87°.

3. The tufted carpet tile of claim 1 , wherein the first edge angle is smaller than the second edge angle.

4. The tufted carpet tile of claim 1 , wherein the third pair of faces consists of a third edge face and a fourth edge face inclined with respect to the first pair of generally parallel faces, wherein a third edge angle between the first pair of generally parallel faces and the third edge face is different than a fourth edge angle between the first pair of generally parallel faces and the fourth edge face, and wherein each of the third and fourth edge angles are the smallest angles measured between the planes defining the first pair of generally parallel faces and each of the edge faces.

5. The tufted carpet tile of claim 4 , wherein the first edge angle is substantially the same as the third edge angle.

6. The tufted carpet tile of claim 1 , wherein the first pair of generally parallel faces comprise squares or rectangles.

7. The tufted carpet tile of claim 1 , wherein the first pair of generally parallel faces comprise rectangles comprising short sides and long sides, and wherein the second pair of faces are along the long sides.

8. The tufted carpet tile of claim 7 , wherein the tufted carpet tile is configured to be coiled into a roll.

9. A carpet comprising:
one or more backings which define a volume having three pairs of faces;
a first pair of faces defining respectively an upper face of said one or more backings and a lower face of the carpet;
a second pair of faces, wherein a first face and a second face of said second pair of faces are each inclined with respect to the first pair of faces by angles of less than 90°, and wherein a first face of said second pair of faces is inclined inwardly from the lower face to the upper face, and a second face of said second pair of faces is inclined outwardly from the lower face to the upper face of the carpet;
a third pair of faces; and
wherein the angle between the first face and the first pair of faces is different than the angle between the second face and the first pair of faces.

10. The tufted carpet tile of claim 9 , wherein the angles are between about 10° and about 87°.

11. The carpet of claim 9 , wherein said first face and said second face are inclined at angles differing from one another by 0.5° to 10°.

12. The carpet of claim 9 , wherein said second face is inclined at a smaller angle than said first face.
