HUEBA/ER,BEEHLER, l l/ORREL HERZ/G, A TTO/VE VS States non, nnurroncnn rm Walter R. Schindler, Los Angeles, Calif, assignor to Hotkap Manufacturing Qompany, Los Angeles, Cahfi, a copartnership Application .lune 21, 1954, Serial No. 437,937 3 filaims. (Cl. 24-2il) The invention relates to ties, namely, ties which can be secured merely by being twisted because of the in herent ability of the tie to hold the shape into which it has been twisted.

Heretofore a number of reinforced ties have been con structed, these ties chiefly featuring two layers of paper between which is cemented a strip of wire. Paper has been prepared in various ways and different types of adhesive material employed, namely, asphalt, glue, etc., for the purpose of holding the strips of paper one against the other and for maintaining the wire reinforcement in place; in many instances the paper employed has been colored on the exterior and in some instances printed with sundry labels.

Although ties of this nature have satisfied a certain need in the industry and in particular the need for very low-priced tying strips both in the nursery industry and in the industry devoted to the packing of vegetables, ties of this kind have not been found suitable on all occasions partly because of their impermanence. Moreover, because of the ease with which paper is torn, when the ties have been twisted to hold them in position in use, in almost all instances the paper becomes torn and the tie becomes unsatisfactory for repeated use.

Moreover, in spite of the use on occasions of waterresistant adhesives, ties of the paper laminated variety ultimately become affected by water and moisture, causing them to deteriorate and ultimately lose the firmness of their application to a package or other item upon which they may be used.

It is therefore among the objects of the invention to provide a new and improved metallic reinforced tie of a particularly permanent and lasting quality.

Another object of the invention is to provide a new and improved reinforced tie of considerable strength though of extremely light weight which at the same time necessitates no employment of adhesive to hold laminated strip portions together and which moreover is substantially moisture resistant to the end that the tie does not deteriorate in the presence of water and moisture.

Still another object of the invention is to provide a new and improved foil reinforced tie which can be made in a particularly decorative and attractive fashion.

Still further among the objects of the invention is to provide a new and improved reinforced tie made of metallic foil material folded over in multiple folds and thereafter molded or formed around the wire reinforcing so that the reinforcing is held in place by the molding of the foil and the folded portions of the foil retain their superimposed relationship after repeated use, and further wherein the edges of the tie are made smooth to avoid cutting.

With these and other objects in view, the invention consists in the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter set forth,

ice

pointed out in the appended claims and illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a view in perspective of a section of the foil reinforced tie.

Figure 2 is a perspective view somewhat similar to Figure 1 wherein portions of the foil strip employed in constructing the tie are folded back to show their man net of application.

Figure 3 is a cross-sectional view of the foil strip and the wire reinforcement prior to the folding operation.

Figure 4 is a cross-sectional view of the foil strip and wire reinforcement after the folding operation and before the foil is pressed in place around the wire reinforcement.

Figure 5 is a cross-sectional view of the tie at the time of molding the foil around the wire reinforcement and including a fragmentary view of rollers suited to the forming of the strip around the reinforcement.

In the embodiment of the invention chosen for the I purpose of illustration there is shown a tie constructed of a strip 11 and a wire reinforcing center element 12. The wire reinforcing center element is ordinarily an inexpensive grade of wrought iron or other metal wire which can be purchased in large quantities at substantially a minimum cost.

The strip material 11 may be of very thin aluminum or other metal foil or, in any event, such material, natural or synthetic, as can be bent and folded along a longitudinal line and which, after having been bent or folded,

. will remain in the folded position.

in the forming of the tie a method may be followed wherein the strip 11 is cut to a width substantially three times the width of the ultimately finished tie 10. Good practice suggests that the strip 11 be colored on one side,

namely, the bottom side as viewed in Figure 3, should a colored effect he required of the finished tie 10. The method followed in forming the tie includes laying the wire 12 along the mid-line of the strip 11 on one side, namely, the unpainted side, if a painted strip chances to be used. Next a side section 14 of one-third the width of the entire strip 11 is folded over a central section 15 and overlies the wire 12. The folding over of the side section M forms a folded edge 16. Next an opposite side section 17, likewise of a Width about equal to onethird of the width of the strip 11, is folded over the top of the first identified side section 14 forming a folded edge 18. The parts now occupy the positions illustrated in Figure 4, there being an exposed free edge 19 of the side section I! and a concealed edge 20 of the side section 14. By having the edge 18 folded and the edge 16 folded and at the same time extending beyond the free edge 19, the edges of the finished tie remain smooth and the cutting character of the foil is entirely eliminated. The folded edges also add considerably to the strength of the tie.

After the parts are thus formed, the folded strip may be passed between a grooved roller 21 and a flat roller 22. It will be noted that the grooved roller 21 may have provided therein intermediate opposite edges a groove 23 having a depth approximately equal to the diameter of the wire 12 and curved with a curvature somewhat greater than the wire 12. The depth and width of the groove, in any event, should be such that when it presses the foil comprising the central section 15 around the wire 12, the wire will be pressed snugly by the surrounding portion of the foil, leaving no appreciable gap. A slight stretching of the foil around the wire will add to the snugness of the folded structure and its generally smooth surfaced appearance.

When this operation is accomplished by rolling the folded section between the roll, the flat roller 22 will form a backing for the rolling operation and assure that the outwardly facing surface of the side section 17 is perfectly flat incontrast to the beaded configuration of the opposite base of the tie.

It will be noted further that should a foil strip be employed which has been painted on one side, namely, the lower side, as viewed in Figure 3, both upper and lower sides of the finished tie will present a painted surface. Moreover, the double thickness of the foil on the sidc: serves as a cushion against the pull of the wire when in use. Some displacement of the wire from precise center may be permitted and a slight bulge on the side of double thickness will not be detrimental. Although metal wire for the Wire 12 will usually be found preferable, the term wire is equally applicable to appropriate materials of nonmetalliccharacter. 3

In use a tie of the type hereinabove described is one of a particularly permanent and lasting quality without the necessity of using any adhesive because of the inherent ability of foil-like material to retain the rolled shape provided in Figure 5. The quality of the material also assures permanence against action of water, moisture and other elements.

Further still, when a multiple folded wire reinforced tie of the type herein described is twisted one strand upon another for use on packages, boxes and sundry other objects, the twists will remain tight and the material can be bent to any number of decorative configurations. The smooth side can readily be presented outermost so that the side beaded as a result of forming the foil around the reinforcement is concealed. Further still, the tie multiple folded over a reinforcing wire in the manner herein described, if desired, can be untwisted, flattened out, and thereafter reused particularly inasmuch as there is little tendency for the folded or laminated pontions of the tie to become torn.

While 1 have herein shown and described my invention in what I have conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of my invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
