Application October 5, 1935, Serial No. 443,733 a claims. (or iii-60) This invention relates in general to cordage atives sucli as cellulose esters, cellulose ethers, nnd in am to an improved decorative tycellulose oxy-ethers; gelatine; casein, and other inn cord and to correlated improvements in the synthetic plastics. These materials may be colmethod of producing the same. cred or uncclored, transparent or opaque.
orative tying cords comprising a plurality In the preferred embodiment of the invention, 5 oil twisted fibrous strands which are now in use the strip of non-fibrous material is given not more for various-purposes have, among others, the imthan 10 twists per foot of cord length, thus reportant defect that when such cords are cut the taming to a substantial degree the flexibility ends tend to untwist, whereby the decorative characteristic of the non-fibrous material. If de- 10 character of the cord is seriously impaired. ,Fursired, the non-fibrous material may be plasticized lo then-more, when one of the strands of the cord with any suitable plasticizer such as is known consists of a strip oi tinsel, the sharp edges of in the art, with the object of still further increasthe tinsel strip tend to cut into the fibrous strands, ingthe flexibility of the cord, producingaroughened surface and weakenin tthe The metallic strand which is spirally wound is strength oi the cord at such points. about the core may comprise a metal wire or a iii lit is, therefore. the principal object of the presnarrow strip of metal such as is commonly called ent invention to provide an improved decorative tinsel". The tinsel is formed preferably by fiattying cord in which certain elements art so comtoning a fine metal wire, since this method gives blood as to resist disintegration when severed a strip having rounded edges and avoids the M d, at the e time, to cflera uniform tensile sharp edges produced by cutting a sheet of thin on strength which cannot be impaired by bending or metal into narrow strips. In another embodiment t. the metallic strand comprises a narrow strip of it is a, specific object of the invention to-proflexible material covered on one or both sides with vide a tying cord of decorative character formed a metallic coating, such, for example, as a strip oi a core of flexible, non-fibrous material and a of transparent cellulose having on one side a mean decorative element encircling the core without detallic coating formed by cathode sputtering of iormi or weakening the core. a metal. The metallic strand preferably contrasts @ther objects oi the invention will in part be in color with the core about which it is wound obvious and will in part appear hereinafter. and may be embossed, crinkled, creped or otherw According to the invention, a tying cord is wise surface roughened so as to reflect light from to ed ofa twisted strip of flexible, non-fibrous a. multiplicity of facets and thus enhance the material about which a relatively flat, thin strand decorative efiect. For example, the metallic having a metallic appearance, preferably a metal strand 2 may be embossed with a plurality of strip having rounded edges, is spirally wound in raised points 3 as shown in Fig. 1. Or the strand 5 open coils in the same direction as that in which 2' may be crinkled to produce a multiplicity of (it underlying strip of non-fibrous material is fine lines t, as shown in Fig. 2.

In view of the known characteristics exhibited any suitable, flexible, non-fibrous material, such, by cell-1110510 Similm lwn-fiblws ter a hen to tor example, as cellulose hydrate; cellulose deriv= twisted, it is obvious that a cord constnlcted of theelements and in the manner above described will, while remaining perfectly flexible, retain its shape without deformation, loosening or disinte gration where tied or severed. Furthermore, the metallic strand, in the preferred embodiment, has rounded edges and the material composing the core is extremely tough and resistant to any cutting action, hence the tensile strength of the cord remains uniform at every point no matter how the cord is used.
Since certain modifications in the article of the invention may be made without departing from its scope, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
1. A decorative tying cord comprising a cord formed of a twisted strip of colored, flexible, nonfibrous regenerated cellulose and a flat, thin metallic strand wound about said core in open spirals.
2. A decorative tying cord comprising a core formed of a twisted strip of colored, plasticized, non-fibrous material and a flat, thin metallic strand spirally wound about said core in the'same direction as the direction in which the core is twisted.
3. A decorative tying cord comprising a core formed of a twisted stripof flexible, non-fibrous material and a strand spirally wound about said core, said strand comprising a narrow strip of flexible material having a metallic coating.
4. A decorative tying cord comprising a core formed of a twisted strip of flexible, non-fibrous material and a strand spirally wound about said core, said strand comprising a strip of transparent, flexible, cellulosic material having a metallic coating.
5. Adecorative tying cord comprising a core formed of a twisted strip of flexible, non-fibrous material and a strand spirally wound about said core, said strand comprising a flat, thin strip 01' tinsel having rounded edges.
6. A decorative tying cord comprising a core formed of a twisted strip of flexible, non-fibrous material and a strand spirally wound about said core in the same direction as the direction in which the core is twisted, said strand comprising a twisted fiat, thin strip of tinsel.
7. A decorative tying cord comprising a core formed of a twisted strip of flexible, non-fibrous material and a strand spirally wound about said core in open coils, said strand comprising an embossed flat, thin strip of tinsel.
8. A decorative tying cord comprising a core formed of a twisted strip of flexible, non-fibrous material and a flat, thin metallic strand spirally wound about said core, said strand having a crinkled surface.
