In accordance with the preferred method of producing the fabric bodies of the present invention, one or more filaments 2l are wound upon a rotatable mandrel 22 so that the adjacent turns or strands are positioned contiguously, whereupon a readily removable adhesive composition is applied to the filaments thus wound tov unite them in the form of a hollow cylinder open at its ends. After the adhesive has set sufficiently, the hollow structure or body 2l thus formed is removed from the mandrel as by cutting the filaments along a line 2B transverse to the winding direction, the adhesive material serving toy maintain the filaments in their assembled relationship. The hollow b ody may then be unrolled or flattened to assume the form of a sheet 2l, which may be utilized as such or subdivided along one or more lines 3l spaced at suitable intervals to form strips or tape-like bodies 32 of desired width and contour. It should be noted that any convenient number of filaments may be fed simultaneously upon the mandrel, and/or the filament or filaments may be wound upon the mandrel in multiple layers if desired.-

The adhesive employed in uniting the filaments should be soluble to provide for its ready removability for reasons to be discussed more completely, and it should at the same time possess sumcient flexibility that the fabric bodieiil can be handled and folded to an extent -sumcient Ator withstand the normal strains encountered in display. sale and use. j 1 l A water soluble adhesive found to be suitable for the purposes of the present invention, is gelatin admixed with suitable proportions ,ofv a softening agent such as glycerin. Many other water soluble adhesivesv suggest themselves, among which are glues, starches, agar, pectin, gums, etc., with which suitable plasticizers, ilexibilizers, softening agents, etc., may be incorporated. Since there are conceivable cases in which the use of water wouldnot be desirable, it is also contemplated to employ adhesives other .than those which are soluble in water. Byway of example only, vinyl resins such as polystyrene or polyvinyl acetate may be employed, accompanied as desired by suitable plasticizers.. In such cases, a suitable solvent such as benzene may be employed advantageously. Adhesives and corresponding solvents other than tho .Specled may be usedliowever, many of which will be su'ggested-upon referring to such well known sources as "The Chemistry of Synthetic Resins" by Carleton Ellis, published 1935 by the Reinhold Publishing Corporation, New York city, andthe adhesive art generally. Adhesives which are soluble in the commoner dryv cleaners for example, might be especially well adapted for use, inconjunction with the present invention.

The filament or filaments used in making the fabrics or tape-like bodies are preferably but not necessarily of textile origin and may well assume various colors, forms and types. The filaments may be unitary or fibrous, mixed or pure, twisted` or untwisted, natural or synthetic. Threads 4composed of wool, cotton,silk, rayon. linen, mineral fibres, etc., or anymixtures may be used. Buch materials may be bleached or unbleached, plain or dyed, solid or multi-colored. It will be under--4v stood that the filaments may be spliced at intervals to provide the necessary length or to achieve various color combinations or designs. Moreover, the `ultimate fabrics or tape-like bodies themselves may be spliced or jointed in longitudinal or superimposed relationship to obtain desired lengths, thicknesses, thread densities, designs, etc. f

As clearly shown in Fig. 4, the fabric body 3 2 is made up of a plurality of filaments running transversely thereof, sufficiently treated with a soluble adhesive 34 to unite the laments and retain them in such extended condition as to produce a structure having the desired characteristics. The adhesive material is preferably sumciently plastic or flexible to permit a reasoneable amount of folding and handling of 'the fabric so that it will resist the ordinary wear and tear encountered in commerce and use. In some cases it may be desired to provide the fabric with assembling or reinforcing means to supplement the adhesive. For example, one or more rows of stitching may be used. Whereas such supplemental means are not regarded as primarily required by this invention, their use should properly fall within the scope of the appended claims.

The adhesive material may be applied to the filament or filaments after winding upon the mandrel, by immersion, spraying, or in any other well known manner. It is also contemplated however, to initially coat the mandrel with the adhesive composition and then wind the lament thereupon. As a matter of fact, if desired, Nthe filaments may be coated on both exposed surfaces or any portions thereof, and the filaments and/or their bers may be or need not be impregnated.

Application of the tape-like bodies or fabrics to a backing to be ornamented may be accomplished in the manner shown in Fig. 5 of the drawing. The fabric is preferably sewed upon a backing 28, such as cloth, by means of one or more rows of stitching 38. Where the fabric isl in the forml of a tape, the stitching is shown as extending substantially medially thereof. Where the fabric is wider. spaced rows of stitching may be used and the fabric subsequently subdivided between such rows. Various other modes of clamping the fabric or tape-like bodies to their backings willY also suggest themselves to those skilled in the art.

After the tape-like or fabric body or bodies have been fixed upon the backing material, the adhesive is removed from the filaments preferably by subjecting them to a suitable solvent. Where a water-soluble adhesive such as gelatin is present. water would be the most logical solvent, but in some cases, if a water-insoluble composition has been employed, a corresponding solvent will be necessary.

After the assembly has been washed free of the adhesive, the threads or filaments will assume their nnal form such as 'that depicted in Fig. 6 of the drawing.l It will be understood of course that if the fabric or tape-like bodiesL are applied to the backing in several layers', after they adhesive has beenremove'd. a much denser pile will result than thatachieved with the use of a single layer,

As depicted in Pig. 7, multiple layers of the fabric or tape-like ,bodies have been applied to a backing il, by means of a row of stitching ll. It will be evident that the several layers may be of a single color or material, or they may vary in these respects depending upon the particular de-` It is conceivable that the adhesively united fabrics and ornamental bodies in accordance with the present invention may be produced by methods other than those specifically disclosed herein. It would be possible, for example, to stretch a plurality of lamentsso that theylie substantially parallel to one another and in close contact, and while thus maintaining them, apply an adhesive composition thereto, resulting in a product similar to that shown in Fig. 3 of the attached drawing. Accordingly, unless otherwise restricted, the claims of the present application should be construed to cover articles of manufacture of the present type however they may be produced. In the case of the method claims, applicant has elected the method disclosed and claimed as being preferred.

It will be understood that the present invention is applicable to the production of 'tuftedarticles of all sorts.
