vWOVEN TAPE Filed June 28, 1939 Patented May 2l, 1940 WOVEN TAPE James A. Hendley, Middletown, Conn., assigner to The Russell Manufacturing Company, Middletown, Conn., a corporation of Connecticut Application June 28, 1939, Serial No. 281,588

2 Claims.

This invention relates to tape, and more particularly to tape which is primarily used as zipper tape.

One object of this invention is to provide an improved tape having elastic and inelastic portions extending side by side and so constructed as to minimize the likelihood of the elastic strands of the tape being cut or broken as a result of sewing operations on the inelastic portion of the tape.

Another object of this invention is to provide an improved tape having elastic and inelastic portions extending side by side and so constructed along the line of juncture of the elastic and inelastic portions as to have maximum neatness and uniformity of appearance.

Another object of this invention is to provide an improved tape having elastic and inelastic portions extending side by side, which can be readily manufactured to produce an attractive, durable construction at minimum cost.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art. 1

In the accompanying drawing in which one way of carrying out this invention is shown for illustrative purposes:

Fig. 1 is a perspective view of a fragment of tape made in accordance. with the present invention;

Fig. 2 is a top-plan diagrammatic view of one form of weave that may be employed in the construction of the tape shown in Fig. 1;

Fig. 3 is a sectional view on line 3--3 of Fig. 2;

Fig. 4 is a perspective view similar to Fig. 1 after cords have been sewed along opposite sides of the inelastic portion of the tape;

Fig. 5 is a top-plan view of the tape shown in Fig. 4 with zipper elements mounted thereon; and

Fig. 6 is a sectional view on line 5 6 of Fig. 5.

In the description and claims, the various parts are identified by specific names for convenience, but they are intended to be as generic in their application as the prior art will permit.

The particular form of tape III chosen for illustration in the drawing comprises an inelastic or non-elastic portion I I and an elastic portion I2. 'Ihe inelastic portion I I has a flrst set of warp strands consisting of a plurality of warp strands I3 of cotton or other suitable material, and the elastic portion I2 has a second set of warp strands consisting of a plurality of warp strands I l of cotton or other suitable material. A pair of catch warp strands I5 of cotton or other suitable mateextends back and forth across the set of warp strands I3 and Il. One or more inelastic weft strands I6. of cotton or other suitable material 5 extends back and forth across the set for warp strands I3 and is looped around the furthest to the left of the warp strands I3 and around the pair of catch warp strands I5 as diagrammatically shown in Figs. 2 and 3. One or more elastic weft l0 strands I1 extends back and forth across the set of warp strands Il and is looped around the furthest to the right of the warp strands I4 and around the pair of catch warp strands I5. The elastic warp strand II is preferably composed of a vulcanized rubber strand covered with a winding of cotton or other suitable textile material, althrough any suitable elastic strand having elasticity similar to rubber may be used either with or without a suitable covering thereon. The 20 broken line I5a, Figs. 1, 2 and 5, is used to indicate the general location of the pair of catch warp strands I5 between the inelastic portion I I and the elastic portion I2.

Prior to using the tape I0 for mounting the zipper elements thereon, cords I8 and I9 of cotton or other suitable material are sewed along opposite sides of the non-elastic portion II, as shown in Fig. 4. Then the zipper elements 20 are mounted on the tape I0 with the arms 2Iv and 22 of each zipper element clamping against the opposite side portions of the inelastic portion II and with the cords I8 and I9 engaged within the opening 23 of each zipper element 20. I'he cords ensure anchoring the "zipper elements securely. 35

While one or more catch warp strands I5 could be used, I prefer to use two in order to accomplish4 a maximum neatness of appearance by avoiding the use of more than two, and minimizing the risk of damage to the tape by use of only one. More than two catch strands I5 would tend to be too bulky and cause too noticeable a ridge along the location of the strands I5. A single catch strand I5 would risk serious damage to the tape in the event that the single strand were to break and release the looped portions of the elastic weft strand I 1, with consequent serious damage to the tape.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equiva-g 2. A woventape comprising: nrst andsecend setsoi'warpstrands: apair ofcatchwarpstrands between said two sets ot warp strands; an inelastic wett strand interwoven with said first set of warp strands and looped around said catch warp strands; and an elastic wett strand interwoven with said second set of warp strands and also looped around said catch warp strands but not interlocked with said inelastic weft strand.
