This invention relates to yarn assemblies and more particularly to prefabricated strips for use in making pile fabrics such as hooked rugs and the like.

It is an object of this invention to provide an improved yarn assembly of the above indicated type which is simple and economical of manufacture and which may be easily and quickly to provide a yarn assembly which greatly facilitates the manufacture of pile fabrics and substantially decreases the time and labor required in the production thereof. I

Itis a. further object of the present invention to provide an improved yarn assembly tor the manufacture of pile fabrics which permits the rapid manufacture of such fabrics even though a considerable color scheme is involved in the final product.

Other and more detailed objects of the present invention will become apparent from an examination of the accompanying drawing in which like reference characters designate like parts throughout and wherein:

Figure 1 is a broken elevational view of a yarn assembly embodying features of the invention;

Fig. 2 is an end view of the structure illustrated Fig. 3 is a broken elevational view of the yarn assembly of Fig. 1 in the compressed or flattened condition;

Fig. 4 is an end trated in Fig. 3;

Fig. 5 is an elevational view showing a plurality of yarn assemblies secured to the backing of a me or the like;

Fig. 6 is a view of the structure illustrated in Fig. 5 after the looped end of yarn and supporting element have been severed;

Fig. 7 is a view of the structure illustrated in Fig. 6 after the severed supporting element has been removed, and

Fig. 8 is a broken plan view of a rug construction using the yarn assemblies of the present invention and illustrating how a. color, pattern may be worked thereinto.

Referring to the drawing, the yarn assembly 8 comprises a flat striplike supporting element it view of the structure illuswhich carries a. strip of mucilage or other suitable adhesive it which extends longitudinally of the element it and is disposed in close proximity to one longitudinal edge thereof, as is best seen in Fig. 3. The element it may be formed of any suitable material and in the preferred embodiment is formed oi paper. This paper strip it supports a continuous length of yarn is which is wound about the paper in a series of continuous helical loops each of which engages the adhesive it which serves to hold the yarn in place on the strip.

- While it will be apparent that the yarn it may be wound aboutthe element it while it is in the flattened condition illustrated in Figs. 3 and 4, it has been found easier and quicker to support the paper it in the shape of a tube or cylinder, as illustrated in Figs. 1 and 2, and to rotate it while winding the yarn it in place. When the yarn it has the tube and yarn together may then be compressed to the flat shape illustrated in Figs. 3

and 4-, care being. taken that in so doing the mueilage strip i 2 is disposed in close proximity to one of the longitudinal edges thereof.

It will be appreciated that the yarn assembly, while having a particular utility in the manufacture oi rugs, is capable of numerous varied applications in the production of pile fabrics of widely varying types.

The yarn assembly a is used in the following manner. The assembly e is placed on a piece of burlap or other suitable backing material i 6, and is sewed to the backing along the mucilage strip it. The assemblies 8 are secured to the backing lain overlapping relation in shingle fashion, as illustrated in Fig. 5. A sharp knife is then inserted between the two thicknesses of the supporting element It and it is cutalong the edge opposite to that secured to the backing it. By this same operation, the loops of yarn are cut at the point element It). The yarn assemblies tlllustrated in lar pile fabrics, since the strips may be made up.

in numerous colors of yarn and the color may been wound upon the tube,-

where they pass over this edge of the backing it, the supportbe changed as desired by merely cutting off the assembly being used and continuing with an assembly of the desired color. when a strip is thus cut off, the adhesive l2 prevents the loops on the strips from coming unwound or being displaced. This construction thus permits the color to be readily changed as frequently as desired. In the rug portion illustrated in Fig. 8, a diagonal purple line illustrated at 20 has been produced by changing the color as described above. It will be understood that any desired pattern may be produced in this manner. As above indicated, the yarn may be wound upon a fiat supporting element, thus eliminating the flattening operation found desirable when an initially cylindrical element is employed. A flat strip of paper or light'cardboard may be used. In either event, whether an initially flat element is employed, or whether an initially cylindrical element is used and flattened during preparation of the assembly 1, it will be apparent that the yarn may be out without cutting the supporting element, and the latter may then be removed by tearing along the perforations formed therein by the sewing operation.

While only one specific embodiment of the invention has been illustrated and described in de- 1 tell, it will be apparent to those skilled in the art that numerous modifications and changes may be made without departing from the spirit of the invention and from the scope of the appended claims.

What is claimed is:

1. A yarn assembly adapted for the production of pile fabrics comprising a longitudinally extending supporting element formed of a material which is easily tom when perforated by a sewing needle, a strip of adhesive material provided along the longitudinal length of said element, and a continuous length of yarn wound upon said element in a series of adiacently disposed loops each of which engages said adhesive material and is held in place thereby.

2. A yarn assembly adapted for the produc-,

tion of pile fabrics comprising a longitudinally extending tube formed of a material which may be readily cut and easily torn when perforated. a strip of adhesive material supported on and extending along said tube. and a continuous length of yarn wound upon said tube in a series of adiacently disposed loops each of which engages said adhesive material and is held in place thereby.

3 A yarn assembly adapted for the production of pile fabrics comprising a longitudinally extending flat strip element formed of a material which then compressed to a flat strip may be readily cut and easily torn when perforated, a strip of adhesive material supported on and extending along said element, and a continuous length of yarn wound upon said element in a series of adiacently disposed loops each of which engages said material and is held in place thereby.

4. A yarn assembly adapted for the production of pile fabrics comprising a longitudinally extending paper tube, a strip of adhesive material supported on and extending along said tube, and a continuous length of yarn wound upon said tube in a series of adiacently disposed loops each of which engages said adhesive material and is held in place thereby.

5. A yam assembly adapted for the production of pile fabrics comprising a longitudinally extending supporting element formed of a material which may be readily cut and easily torn when perforated, a strip of adhesive material supported on and extending along said element, and a continuous len th of yarn wound upon said element in a series of adiacently disposed loops each of which engages said adhesive material and is held in placethereby, said supporting element being adapted to permit said yarn to be secured to a backing material by sewing through said yarn and said supporting element.

6. A yarn assembly adapted for the production of pile fabrics comprising a longitudinally extending supporting element formed of a material which may be readily cut and easily torn when perforated, a strip of adhesive material supported on and extending along said element, and a series of adjacently disposed loops of yarn each of which engages said adhesive material and is held in place thereby, said supporting element being adapted to be supported in tubular shape while said yarn is wound thereabout and shape.
