This invention relates to floor coverings, such as rugs and the like. and is more particularly directed to means connected to the rug itself for preventing any curling. effect at the end of the 5 rug and particularly at the corner portions thereof.

One of the important features of the present I invention consists in impregnating some of the weft shots at the end of the rug with an adhesive l so that the end weft shots and their associated warp threads shall be held in their woven rela- 20 In the drawing:

Fig. 1 is a perspective view of a. rug of conventional type provided with the present invention and showing the end portionsof therug turned to present the backing fabric;

Fig. 2 is a section on the line 2--2 of Fig. 3; Fig. 3 is a development of the rug showing its rear surface or backing fabric; and Fig. 4 is an enlarged detail showing one of the corner pieces secured to the backing fabric by the 30 adhesive and engaged by theserging which may be employed in 'connectionwith finishing the edgesof the rug.

The rug I may be of the conventional type having a pile tread surface 2, as more clearly 5 indicated in Figs. 2 and 4, and a backing fabric 3 which furnishes the foundation to which the pile forming yarns may be secured.

It is common practice to bind up the ends of rugs by turning under and stitching to the backing fabric a protruding portion of backing fabric woven without pile and known in the tradeas a heading. Such rugs are woven end'to end in a connected series with the pile surfaced rug sections connected by headings of backing fabric 5 from which the pile tufts have been omitted.

These rug sections are separated by cutting the headings transversely, after which the severed headings are folded back and secured to the under surface of the backing fabric to bind the rug ends.

50 Where the rug is notprovided with a heading.

as is illustrated in the present form of the in-' vention, the end weft shots are liable to become displaced and so as one of the features of the present invention the end weft shots are impreggg nated with an adhesive, one form of which may be latex, although the invention is not necessarily limited to such form of adhesive.

The stipplings shown by the dotted zone 4 extends transversely of the end portion of the rug and binds the end weft shots in place whether the rug is provided with a heading or not. The adhesive which impregnates the end shots of the rug serves not only to hold the end threads in their woven condition but to impart to the end portion of the rug a stiffening effect, and in some cases the adhesive alone may be suilicient to accomplish some of the purposes of the present invention.

As a further means for preventing the upward curl of the end portions of the rug and particularly the corners thereof the present invention provides triangular sheet material 5 which 'may be preferably, though not necessarily, of the leno fabric type, and such corner sheet material is secured adhesively to the backing fabric, with the result that all tendency of the corner portions of the rug to turn upwardly is eliminated.

As indicated in the present instance of the invention the corner pieces of sheet material are shown as of triangular shape to fit the corners of the backing fabric but, of course, the particular shape may be variedto suit conditions of use and the invention is not intended to be limited to this particular shape. v

The edge portions of the rug are supplied with a serging'ii, more particularly shown in Figs. 2 and 4, and suchserging, as indicated in Figs. 2 and 4, not only binds the edge portion of the rug, but engages the adjacent edge portions of the triangular shaped sheet material and thereby serves to increasingly prevent displacement of the sheet material relatively to the backing fabric.

In applying the adhesive to the end shots it is found expedient to moisten the rows of shots with a proper penetrating agent, such as Igepon, prior to the application of the adhesive, with the result that the subsequently applied adhesive penetrates the thread structure atthe end portion of the rug.

As hereinbefore stated, the corner reenforcing pieces are preferably formed of the leno type of weave which may be additionally secured to the backing fabric by a lacquer sealer whichlends to the corner pieces an additional means for securing such pieces in place and imparts to the comer pieces a stiffening which contributes to hold the corner portions of the rug flat upon the floor when in use.

What is claimed is:-

1. A pile fabric floor covering of the non- 55 of the backing in the end portion of the covering being held in their woven condition by an adhesive impregnating the said end portion and serving to stifi'en the same, triangular corner pieces secured by said adhesive to the under surface of said backing in the stifiened end portion, and serging additionally securing the two side edges of each triangular piece to the edges of the backing fabric.
