I 1 Claim. 1

This invention relates to elastic tape and more particularly to the selvages thereof.

It is the general object of my invention to provide a novel and improved selvage structure in such elastic tape, so constructed that a firmer and tighter selvage is attained and that the edges of the tape are given a more finished appearance.

To the accomplishment of this object, I have provided a new and improved weave structure in an elastic tape.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.

A preferred form of my invention is shown in the drawings, in which Fig. 1 is a plan view of a portion of my improved tape; and

Fig. 2 is a weaving draft thereof.

Referring to Fig. 1, my improved tape as shown comprises a selvage strand S at each edge. each strand comprising one or more selvage rubber warps ill. I also provide cotton body warps ii and non-elastic weft threads i2. Between each two groups of cotton body warps H I interpose a rubber body warp l4.

Between the cotton body warps H and the rubber selvage warps I I interpose a rubber binder warp I5. All of the rubber warp threads are commonly covered.

When two or more selvage warps III are used, they are preferably woven together, forming in effect a doubled or multiple thread. The rubber warps III, M and 15 are preferably woven one up and one down. and with all of the body warps M in the same shed as the selvage warps ill.

The cotton body warps H are preferably woven two up and two down, with adjacent warps alternated. The interposed rubber binder warp i5 alternates with the selvage warps ID. The opposite selvage, not shown, is similarly constructed. The rubber warps are woven under tension and the cotton warps are relaxed in the finished tape.

Fig. 2 shows the raised warps for successive picks, in the usual draft form.

The addition of the binder warps l5 and the cross-weaving of the same with the doubled selvage warps I0 is found to greatly improve the appearance of the selvages in an elastic tape. It makes the selvages more tight and firm and gives the whole tape a more finished appearance.

The particular weave shown in the body of the fabric is illustrative only and may be varied to suit conditions.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

An elastic tape comprising an elastic selvage strand, elastic body warps, textile body warps disposed in groups alternating with said elastic warps and with each group comprising a plurality of non-elastic warps, an elastic binder warp for the selvage interposed between said selvage strand and the next adjacent group of non-elastic body warps, and non-elastic weft threads for said tape, said elastic selvage strand and said elastic binder warp being woven one-up and one-down but in opposite sheds, and the next adjacent nonelastic body warp being woven, at least in part. in a different shed from said elastic binder warp.

JOHN V. MOORE.
