3 Claims.

In the making of tufted rugs in the conventional manner it is the common practice to employ a backing layer of canvas or the like through which parallel rows of cut tuft Stitching are sewed, the

5 looped tufts being cut on the top side of the rug to afford a continuous pile surface which covers over and conceals the backing material. With rugs of this character, however, difficulty has been experienced in so forming the tufting around the edge of the rug as to overlie and conceal the edge of the backing layer, and the present invention is directed to a method of stitching the edge portion of the tufted rug in such a way as to crowd outwardly the marginal row of tuft stitching, with the result that the spread tips of the tufts will overlie the edge and conceal the same and afford a suitable and attractive finish for the rug.

Further objects and details will appear from a description of the invention in conjunction with the accompanying drawing, wherein,-

Figure? 1 is a rear elevation of a tufted rug displaying the principles of the present invention;

Fig. 2 is a section taken on line 2 of Fig. 1; and

Fig. 3 is a Section taken on line 3 of Fig.`1.

The rug comprises a backing layer I which is preferably formed of one or more layers of canvas or similar material, two plies or layers being shown in Figs. 2 and 3 for purposes of illustration. Around the margin of the backing is sewed a I'lnishing tape I I which overlaps the opposite faces of the backing and serves to afford an edge finish therefor.

The body of the rug is formed in the conventional manner by sewing parallel rows of cut tuft stitching I2 on a tufting machine and extending the rows longitudinally of the rug from end to end thereof save for a narrow marginal space which is provided for the reception of the Special form of tuft stitching which constitutes the principal featureof the present invention.

The rows of cut tuft stitching I2 as shown in Fig. 2 comprise closely drawn loops I 3 which abut against the under surface of the backing, and upstanding spread tufts I4 which are formed by cutting the tuft loops and allowing the strands of the yarn to spread and afford a continuous pile surface.

In order to afford the edge nish of the present invention, I run a marginal row of cut tuft stitching I5 completely around the rug and in very close proximity to the margin. Inside of the marginal row I run a double row of tuft stitching I6 which parallels the marginal rows and serves to overlap and anchor the ends of the rows of body stitching and at the same time serves to crowd outwardly the tufts I'I of the marginal row I5, with the result that the tufts I1 instead of standing upwardly from the surface of the 5 backing will extend outwardly and downwardly over and around the edge of the rug and will thus serve to protect and conceal the taped edge of the backing, which imparts the desired finish to the rug.

In order to afford the required crowding effect, it is desirable to double or duplicate the inner marginal row I6 either by sewing a second row of cut tuft stitching in superposed position to the first row, or by sewing two rows in closely adl5 jacent lateral relation to one another, the intention in every case being to unbalance the tufting along a line adjacent to the margin with a view of introducing an increased-amount of tufting along this line for the purpose of crowding out- 2O wardly the tufts of the marginal row I5 over and beyond the edge of the backing. It will therefore be understood that in claiming the invention I have in mind the use of any method of tufting which will have the effect of increasing 25 the density of the tufts at a point immediately adjacent to the margin in such a way as to effect an outward crowding of the outermost tufts beyond the margin of the backing.

By reason of the displacement of these outer tufts in the manner described, an edge nish is obtained, without, however, so thickening the tufting at this point as to appreciably modify the exposed texture of the pile surface, so that as Viewed from above it is practically impossible to discern the presence of an extra ro-w of tufting introduced into the rug in the manner described.

Although it is commonly the practice to form the body of the rug pile within the marginal area by the employment of parallel closely spaced rows of cut tuft stitching, the present marginal finish may be applied to tufted rugs in which the body tufting is otherwise disposed either by the use of crossing lines of stitching or lines laid in any other appropriate manner.

I claim:

1. Ihe method of producing a tufted rug which consists in running spaced lines of cut tuft stitching through the backing of the rug to produce a pile surface extending over the major portion of the body of the rug, running a line of marginal cut tuft Stitching in close proximity to the margin of the backing, and in running double lines of cut tuft stitching in substantial Contact with one another through the backing l5 inside of and equally spaced from the marginal line and in suiciently close proximity thereto toi laterally displace the marginal tufting and crowd the marginal tufts beyond the edge of the back'- ing to produce a marginal tufting and Yconceal the edge of the backing.

' 2. Y The method of producing a tufted rugwhich consists in running substantially uniformly spaced linesA of cut tuft stitching through the backing of the rug to produce a pile surface of substantially uniform density over the major por-nV l of the marginal line and in such spaced relation thereton as to increasefbeyond normal V'the density ofthe tufting in the region adjacent to tion ofthe body of the rug, running a line of marginal cut tuftstitching in close proximity to the margin of the backing and in Yapplying out tuft stitching through the backing inside of and in substantially parallel relation to the marginalV lineand in properly spaced relationship thereto Vto increase beyond normal the 'density ofthe tufting in the region adjacent to the margin of the rug to the extent necessary to crowd thernar- Y ginal tufts laterally beyond the edge of the back- 2,o2o,s92 Y A ing to produce an edge tufting and conceal the edge of the backing. Y

3; As a new article ofrmanufacture, a tufted rug consisting of a backing of heavy material, l lines of cut tuft stitching extending through the backing and in substantially uniformly spaced relation to afford a substantially uniform pile surface throughout the rug, a marginal line Vof cut tuft stitching in close proximity tothe margin of theY backing'and cut tuftV stitching applied Y10 'Y in substantially parallel relation to `and inside the marginal line, the tufting of themarginal 15 line being outwardly displaced by the increased density of the .adjacent tufting to project beyond the edge ofthe backing in position to overlie and substantially conceal vthe edge of the'backing,
