Claims priority, appliean'on Netherlands December 23, 1952 s claims. (121.1394391) This invention relates to carpets, rugs, mats, licor coverings and the like having a cut pile.

A disadvantage inherent in plain woven fabrics with a cut pile for oor covering in the full sense resides in the appearance of shadowing or shading therein due to a change in the direction of the pile which gives the impression of small or large wet stains.

A similar phenomenon is present in Jacquard weavings in which large plain tields are present in the design. Up to the present time the above phenomenon has not been eliminated and it is an object of the present invention to provide means which will overcome such appearance.

A further object of the invention is to provide a solution for this problem without the necessity of using any new machines.

A further object of the inventi-on is to provide a product which is Jacquard-woven with two or more than two frames while employing two or more than -two groups of pile threads which only differ slightly in color in such a way that the entire product or the plain lield gives the impression of a plain woven product which as non- Sacquard fabric is formed with a single frame of pile threads.

A surprising feature of the invention is that there is obtained in this way pile or velvet carpets and similar products which give the impression of a plain woven fabric without producing in use any change in the direction of the pile or at least without such a change becoming perceptible. O

A still further object of the invention is to provide the groups of pile threads of different shade in equivalent or substantially equivalent amounts.

A still further obiect of the invention is to provide alternate groups of pile threads of different colour, groups of similar coloured threads being spaced from one another at relatively short distances of the order of somemillimeters.

When such groups of pile threads of diterent colour are present in a checkered design the prejudicial elect' mentioned above is still better avoided.

Finally, the invention comprises equally a wovenl fabric of the type above indicated composed of a plurality of strips and the like placed together to form the mentioned products.

The invention relates also to Jacquard fabrics in which the large tields of the design give the impression of being plain woven.

Even though the invention is not limited therein, there is chosen preferably distances between the small groups of pile threadsof the sa'me colour in such a way that these distances may be4 two to tive millimeters. The small groups of pile threads of the same colour can show as seen from above the form of small triangles, of small squares, .or of small irregular polygons whereby it is preferred to use an irregular checkered design.

Though the Jacquard system is practically used exclulively for the manufacture'of fabrics with designs, this Zhi atented 0st. 9, i956 is made according to the invention to obtain plain weavings or products which themselves or whose tields give practically the impression of plain woven fabrics.

With the above and other objects in view which will become apparent from the detailed description below, the invention is shown in the drawings in which:

Fig. l is a partial view'of a carpet constructed in accordance with the invention and Fig. 2 is a cross-section enlarged illustrating the pile threads in different colour.

In Fig. 1 the carpet is indicated at 5 and in such ligure the pile lthreads of one color are identified by 6a and the slightly different coloured pile threads are indicated by 6b. Asshown, such threads form an irregularly checkered pattern of spaced groups of similarly colored pile threads between which are groups of slightly different colored pile threads which prevent the disadvantageous effect mentioned above.

In Fig. 2 the warp threads are indicated at 7 and the weft at The pile threads 9 of one color and pile threads 10 of a slightly different color are held in place. The threads 9 are of a slightly lighter shade of the same colour as the threads 10 which has been shown in the drawing by making the threads 10 of heavier lines than the threads 9. During the weaving the threads 10 of a slightly darker shade are not looped at the same time as threads 9, so that they lie beneath the tufts formed from the loops of the threads 9 in the linished carpet. Likewise, the threads 9 are not looped at the same time as the threads 10, so that they lie beneath the tufts formed from the loops of the threads 10 in the finished carpet.

It is thought that the invention and its advantages will be understood from the foregoing description and it is apparent that various changes may be made in the construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing its material advantages, the article hereinbefore described being merely a preferred embodiment of the invention.

I claim:

1. Carpeting and the like comprising a plurality of groups of tufts of cut pile threads of the same material, a portion of said pluralityl of groups being a slightly different shade of the color of the remaining plurality of groups, said portion being interspersed among said remaining groups whereby the said carpeting is given a umform appearance and shading i prevented.

2. Carpeting as claimed in claim 1 in which the said remaining plurality of groups and said portion of said plurality of groups having a slightly dilerent shade of the color of said remaining plurality of groups are substantially equal.

3. Carpeting as claimed in claim 1 in which said portion of said plurality of groups Iisinterspersecl among said remaining plurality of groups in an irregular checkered pattern.

4. Carpeting as claimed in claim l in which groups of tufts of the same shades are spacedfrom each other a distance of frbm 2 to 5 mm.

5. In 'a fabric of tufted cut pile threads of the same material, that improvement comprising spaced groups of tufts of one shade of a color, and the groups o f tufts .interspersed between said spaced groups of tufts being a slightly different shade of the same color.
