Abstract

A novel carpet and fabric carpet backing are disclosed which include a guide for orienting the carpet with respect to machine direction. The carpet comprises a face portion and a fabric backing with an exposed surface visible from the back side of the carpet. The fabric carpet backing includes a plurality of linear patterns visible from the exposed surface running generally parallel to each other and generally parallel to the same edge of the carpet and running the length of the carpet. Each of these linear patterns includes at least a first and second linear sub-pattern running the length of the pattern. The first and second sub-patterns are visually distinct from one another and are disposed in the same position relative to the other and relative to the edge of the carpet in each of the linear patterns. As a result, a guide is provided by these linear patterns for orienting the carpet with respect to machine direction and left/right, even if the carpet is cut on a line between any two linear patterns. Preferably, the linear patterns are made by weaving yarns of two different colors into the backing in the machine direction.

Claims

1. A carpet comprising:

a face portion

a fabric backing with an exposed surface visible from the back side of the carpet, and with an edge running the length of the carpet; and

a plurality of linear patterns visible from the exposed surface running parallel to each other and parallel to the edge and running the length of the carpet, each of said linear patterns comprising at least a first and second linear sub-pattern running the length of the pattern, with the first and second subpatterns being visually distinct from one another, the first sub-pattern in each linear pattern being disposed closer to the edge than the second sub-pattern in that linear pattern, each of the linear patterns being asymmetrical about a center line passing between the first and second linear subpatterns;

whereby a guide for orienting the carpet with respect to machine direction is provided, even if the carpet is cut on a line between any two linear patterns.

2. The carpet of claim 1 wherein the first linear sub-pattern is a line having a first color and the second linear sub-pattern is a line having a second color different from the first.

3. The carpet of claim 1 wherein the first linear sub-pattern is a dashed line and the second linear sub-pattern is a solid line.

4. The carpet of claim 1 wherein the first linear sub-pattern is a dashed line and the second linear sub-pattern is also a dashed line which is visually distinct from the dashed line of the first linear sub-pattern.

5. The carpet of claim 1 wherein the first linear sub-pattern is a solid line and the second linear sub-pattern is a solid line with a noticeably different width than the solid line of the first linear sub-pattern.

6. The carpet of claim 1 wherein the carpet backing is a woven fabric and the first linear:

sub-pattern is formed by weaving a yarn of a first color in the fabric and the second linear sub-pattern is formed by weaving a yarn of a second color different from the first color in the fabric, and wherein the first and second colors are different from the color of the other yarn in the backing.

7. The carpet of claim 6 wherein the second linear sub-pattern includes two yarns of the second color which are both on the same side of the yarn of the first color in each of the linear patterns.

8. The carpet of claim 6 wherein the yarns are woven into the fabric in the machine direction.

9. The carpet of claim 8 wherein at least three linear patterns are evenly spaced across the width of the carpet backing.

10. The carpet of claim 9 wherein the linear patterns are spaced at intervals between about 2 feet and about 4 feet.

11. The carpet of claim 9 wherein the linear patterns are spaced at intervals of about 3 feet.

12. The carpet of claim 1 wherein the linear patterns are printed on the exposed surface of the carpet backing.

13. The carpet of claim 12 wherein the linear patterns are printed on the exposed surface of the carpet backing before the backing is applied to the rest of the carpet.

14. The carpet of claim 1 wherein the carpet backing includes at least four linear patterns located generally symmetrically across the width of the carpet backing.

15. The carpet of claim 1 wherein the linear patterns run the length of the carpet in the machine direction and wherein the linear patterns are spaced between about 2 and about 4 feet across the width of the carpet backing.

16. A carpet comprising:

a face portion

a woven backing with an exposed surface visible from the back side of the carpet, and with an edge running the length of the carpet; and

a plurality of pairs of colored yarns woven into the backing so as to run parallel to each other and parallel to the edge and to run the length of the carpet, each of said pairs comprising a first yarn of a first color and a second yarn of a second color different from the first, said first and second colors being different from the color of the yarns in the rest of the backing, the first yarn of each pair being disposed closer to the edge than the second yarn in that pair;

whereby a guide for orienting the carpet with respect to machine direction is provided, even if the carpet is cut on a line between any two pairs of yarns.

17. The carpet of claim 16 wherein each of the yarns is woven into the fabric in the machine direction.

18. The carpet of claim 16 wherein at least three pairs of yarns are evenly spaced across the;

width of the carpet backing.

19. The carpet of claim 18 wherein the pairs are spaced at intervals between about 2 feet and about 4 feet.

20. The carpet of claim 18 wherein the pairs are spaced at intervals of about 3 feet.

21. The carpet of claim 16 wherein an additional yarn of the second color is woven into the backing so as to be parallel and adjacent to each of the second yarns.
