PATENT OFFICE 1,958,033 TRANSPARENT RIBBON Adolph H. Cohn,

Du Pont New York, N. Y., assignor to Cellophane Company, Inc., New

York, N. Y., a corporation of Delaware Application January 19, 1933, 'Serial No. 652,520

' 4Claims.

1. This invention relates to ribbon. The invention will be described with relation to the manufacture of fancy ribbon for tying bundles, but this particular description is adopted for 5 facility only and does not limit the invention.

2. Merchants to make their packages attractive to prospective purchasers and individuals to make their gifts attractive to the receivers have demanded new and better wrapping and binding materials. The regenerated cellulose wrapping material has satisfied the demand for smart and attractive wrappers but the art appears to provide nothing equivalent in the way of a binding material.

3. It is an object of this invention to provide a new and useful article of manufacture in the nature of a ribbon. Another object of the invention is to provide a binding material. Another object of the invention is to provide a strong, laminated ribbon. Other objects of the invention will be in part apparent and in part hereinafter set forth.

4. The objects of the invention are accomplished, generally speaking, by a ribbon having a thin and flexible body portion whose edges are protected by strips of similar or dissimilar material folded over and bonded to them, which is preferably transparent and preferably made of regenerated cellulose, cellulose acetate or the like.

5. In the drawing Figure l is an exploded view of one form of my invention. In this figure, 10 is a ilat strip of the material forming the body portion of the ribbon, and 11 and 12 are strips of similar material folded lengthwise. In makin the ribbon a strip, preferably the edges of the body strip, is coated with a suitable adhesive, the edge strips are folded over the edges oi the body strip 10, protecting it against teari and making a ribbon stronger than one would expect from the mere quantity of material used, and providing edges of diflerent color from the center portion. This last effect can be enhanced by the use of edge strips of color diilerent from the center ltl'lb.

0. Inl'lgurca2 and 3 are shown a perspective view and cross-sectional view, respectively; of

the ribbon described in connection with Figure 1. In Figures 2 and 3,10 is the body portion; 11 and 14 are edge strips and 13 is a bonding agent which holds the binding strips to the body portion of the ribbon.

i. In Figure 4 is shown a form of the invention in which the ribbon has a bo y-portion including a plurality of strips. In this figure, 20 are? superimposed strips of regenerated cellulose: 21 22 are binding strips of regenerated cellulose which protect the edges of the strips of the body portion; 23 indicates a suitable adhesive; 24 indicates grains of metallic dust or the like included between sheets of the body portion which are present for the purpose of enhancing the decorative effect of the ribbon.

8. Figure 5 is a view enlarged to show the adhesive. Any suitable adhesive may be used to 5 connect the strips but a transparent and odorless adhesive is, for obvious reasons, to be preferred. It will be apparent to persons skilled in the art that the type of adhesive used will vary somewhat with the kind of material. For instance, with gelatine and some kinds of regenerated cellulose an aqueous adhesive is satisfactory whereas with moistureproofed material a nonaqueous adhesive is to be preferred. In some instances a simple solvent for the cellulose derivative may be employed. For instance, beta methoxy ethyl alcohol may be used to bind an edge strip of cellulose acetate to a body portion of cellulose acetate, benzyl cellulose, or the like. In joining the strips the strips may be coated go with adhesive at the moment of application or a strip may be previously.prepared with a coating of adhesive to be activated by application of heat, pressure, or a'reagent such as water or a solvent.

9. My ribbon is'preferably made of transparent regenerated cellulose but it may be made of opaque regenerated cellulose or of transparent or opaque materials such as the cellulose esters and cellulose ethers including cellulose nitrate, o cellulose acetate, benzyl cellulose, and may even be made of gelatine or of certain resinous compositions although the gelatine and resins are much inferior to the other materials. The use of paper or cloth binding strips is undesirable though possible. The material may be moistureproofed if desired.

10. Alternative forms of the ribbon can be made by superimposing strips of unequal width, fpldingthe excesswidthofthewiderltripover 1 theedges ofthenarrowerstripandbondinlthcm thereto with a suitable adhesive. as in Figure 6, and by the use of an edge strip having multiple folds for great strength, as in Figure '1.

11. A decorative appearance can beobtained 10 by using edge strips of different color than the center strip, by including metallic dust or the like in the adhesive or cast in the ribbon material, byuseofadyeintheagentusedtowetthe water or solvent activated adhesive, by including no strands of decorative and/or strengthening materials such as cords between laminations or between adhering surfaces.

12. An advantage of the invention is in the provision of a ribbon having superior characteristics of strength and appearance. vantages of the invention will be apparent.

13. As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that I do not limit myself to the specific embodiments thereof except as defined in the appended claims.

I claim:

1. A binding tape comprising a strip of nonfibrous cellulosic material and strips of non- Other adfibrous celiulosic material folded over and bonded to the edges thereof.

2. A binding strip comprising a plurality of non-fibrous cellulosic strips having their edges bound by flexible strips folded thereover and bonded thereto;

3. A binding strip comprising a body portion
