ASSIGNOR TO BIGELOW-SANFORD A CORPORATON OF MASSA pplicaton led Haren 24, 1931. Serial No. ta/fifth This invention relates to pile fabrics such as carpets and rugs wherein the pile effect or surface is produced by pile forming yarn or threads secured to a backing of warp and 5 weft threads.

In some Oriental floor coverings, such for instance as Chinese rugs, an embossed eect is sometimes produced by slightly trimming the ground pile area which surrounds the iigig ure or pattern after the 'fabric is woven and completed. v This trimming operation is perormed by hand and is subject to the inherent imperfections due to manual trimming and in such loor covering practically all of the is ground pile is of the same height as the figure and yet produces an embossed effect.

One of the obiects of the present invention a is to provide a floor covering such as carpets and rugs and method of making the same with a pilesurfaoeformed of a ground pile area and a figure `or pattern pile area an wherein one orl more or pattern pile area are omitted to-fornr a space between the ground and ligure or pattern pile area and therebyproduce in the iigure or pattern pile 'area a contrasting appearance resembling an embossed ellect. -f

The pile forming yarns or threads fare usually arranged in transverse rows and are secured to a'backing fabric, and in accordance with the present invention each row where the figure or pattern and ground occur has omitted therefrom one or more pile forming yarns or threads to produce a space or separation between the ground forming pile and the figure or pattern forming pile, with the result that during the weaving operation the contrasting appearance or embossed eiiect is produced free from all imperfectionsof v the hand trimming operation as heretofore practiced to some extent.

' An enhancement of the embossed ede'ct may bel secured in some cases by forming the ground pile and the figure or pattern'pile of different ply yarns, and where the figure pile yis produced by. a larger or'heavier ply yarn than the ground pile, the embossed etl'ect becomes pronounced and emphasized during wear, and especially is this the case Where the of the series of pile forming yarns or threads'ad3'acent the iigure y pitch or number of threads per inch re mains constant.

The invention and novel features thereof will best be made clear from the following description and accompanying drawings of one embodimentthereof.

Fig. is a perspective view of a pile fabric containing the present invention, the edge of the fabric being shown in longitudinal section; and- Y i Fig. 2 is a cross section.

The fabric shown by the drawings is of the Axminster type wherein the pile forming areas are produced by pile forming yarns secured to a backing fabric, and while the backing fabric shown is illustrative of one character or construction thereof it is to be vunderstood that the backing fabric may be of any desired character and comprise any usual combination of warp or weft threads for binding or supporting the pile forming` As shown in the present embodiment of the invention the backing fabric comprises the weft threads 2 at the back of the fabric, theintermediate weft threads 3 in the cen- Y tral portion of the fabric and the top or surface weft threads 4, but as hereinbefore stated this is merely illustrative of one character of backing fabric that may be employed and in the present instance of the invention the series of weft threads 2, 3 and 4 are arranged in pairs, signifying thereby that the weft threads have been introduced into the shed 'by needle mechanism.

Between the back weft threads 2 and the intermediate weft threads 3, the present illustration of the invention shows a stutter 5 and likewise between the intermediate weft threads 3 and the surface weft threads 4 is another stuiler 6, the weft threads and stuiiers being bound together by the warp threads 7. The backing fabric thus described may be of usual construction, however.

As shown in the present illustration of the invention the ground forming pile yarns 8 and the figure or pattern forming pile yarns 9 are bound or secured to the backing .fabric by passing about two of the intermediate 'spectively may yar s may weft threads 3, but as hereinbefore indicated the pile forming yarns constituting the ground and ligure may be secured to the backing fabric in a variety of ways since such eature does not form an essential element e present invention. he ground pile area l0 and the figure pile area ll have a defined separation about the contour of the figure as indicated at.l2, and such separationof the two areas is produced e contrasting appearance between the ground pile area and the figure pile area may be emphasized by forming the two pile formintroduced into and secured to the backing fabric in transverse rows and in order that the space between the ground pile area and the figure pile area l0 and 11 rebe formed to bring out the embossed eifect or appearance one or more of the pile forming yarns of each row where the ground and gure come together are omitted.

In the illustrated embodiment of the invention the ground pile area 10 is made` of a two ply yarn as indicated in in the figure or pattern pile area the yarn is of three ply and the setting is arranged so as to leaveout one or more ends of the ground pile area directly adjacent to the figure pile area to be produced. is may not always i necessary as an embodiment of the invention since the pileforming yarns of both the ground and figure may be of the same ply.

he use of a three ply yarn in the figure and a two ply yarn in the ground with the saine pitch or number of threads per inch retained throughout, and the obvious crowding of the heavier yarns in the figure, has a tendency portion of the pile yarn conreason of the ground p`ile area being more sensitive to the tread.

s liereinbefore indicated be introduced understood, as for instance, in the production of an Axminster fabric tube frames may be employed for delivering the pile yarn material to the warps, or nippers or grippers may be employed as now well understood for weaving such- Axininster fabric either face up or face down, or the fabric may be woven on a Jacquard loom wherein all the frames are alive with separate grids for lifting the Fig. 2 while th p threads,

fabric and pile forming threads or the pile may be variously produced by any of the mechanisms now well understood in the art, the essentials of the invention being that between the figure forming pile yarn and the ground forming pile yarn a space be provided b.l erably of the ground adjacent to the periphery of the figure, thereby bringing out and emphasizing the contrasting appearance or embossed effect. Ifv desired the fabric may be sheared as usual, and by a subsequent washing operation the pile areas are softened l cause tl flatten somewhat directly adjacent to the outline of the gure whereby a still further effect may be produced.

l,"Vliat is claimed is f .As an article of manufacture, a woven a pattern pile area an effect of increased contrast.

2 As an article of manufacture, a woven fabric com irisine a backinnr of interwoven l e n warp and weft to a figure pile area and a ground tEile area of different color, one Series at least of the pile forming yarn about the figure pile area being omitted during weaving to cause a separation between the figure ile and ground pile to produce a contrast ofp ance between the figure pile area and the ground pile area.

yarns and a number about the outline of the fi being omitted during weaving to produce in the iigure pile area an embossed effect or appearance.

5. As an article of manufacture, a woven fabric having a bacln'ng of warp and weft and a pile surface which comprises a ground pile area formed of. a two ply yarn,

and a figure pile area formed of a three ply yarn, and one of the series of the ground two p15T yarn adjacent the ligure pile area being omitted to produce an embossed elect in the figure pile area.

6. As an article of manufacture, a woven fabric having a backing of warp and weft threads, and a pile surface, comprising, a. ground pile area and a figure pile area., said two pile areas being formed of different ply yarn and woven with the same pitch, and a number of pile forming yarn adjacent the outline of the figure pile .area being omitted to produce in the figure pile area. an embossed effect.

7. The method of producing a figured pile fabric having an embossed appearance, which consists in weaving a backing fabric, securing transverse rows of ground and figure producing pile forming yarn to the backing fabric and omitting from each of said rows during weaving one or more of the pile forming yarn about the contour of the figure to form a space between the ground pile and iigure pile and produce a contrast of appearance between the figure pile area and the ground pile' area.

' 8. The method of producing a figured pile fabric having an embossedappearance, which consists in Weaving a backing fabric, introducing successive rows of pile forming yarn to the backing fabric for the production of -the pile ground and pile figure, and omitting from each row of pile forming yarn during weaving, a ground forming pile yarn at a point next to the contour of the pile figure to form a space between the ground pile and gure and produce a contrasting appearance between the figure pile area and the ground pile area.

9. As an article of manufacture, a woven` pile fabric comprising a backing of warp and weft threads, a ground pile area formed of pile yarn of one color or combination of colors, and a figure pile area formed of different color or combination of colors, one or more of the series of pii'e forming yarn about the ligure pile area being omitted during weaving to form a space about the figure pile area and produce a contrast of appearance between lthe iigure pile area and the ground pile area.

In testimony whereof, I have signed my 55 name to this specification. e
