8 Claims; (01. 0-'-.-1).

1. This invention relates-to-a-ba-g, andmoreparticularly to labeled open-mesh bags.

Th principalobject of the'invention is the moreeconomical provision of labeled open mesh bags of a type having'a strip'of label material peripherally encircling the open-mesh bagbody on the outside thereof and adhesively secured thereto. In general, accordingto the invention,

this object'is attained'by making the bag-of open-- mesh fabric which is characterized in having been woven so as to have'a band wherein each of the yarns extending lengthwise of the hand is *of substantially lesser weight than the remainderof the yarns of the fabric,- the label strip having a width corresponding to the width of theband peripherally encircling the bag body on the out sid thereof over the band andadhesively secured thereto. apparent and in part pointed out hereinafter;

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structures. hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which several of various possible embodiments of the invention are illustrated,

Fig. 1 is a plan view of a composite web from which bags of this invention are made;

Fig. 2 is a plan viewof a bag made from the composite web of Fig. 1;

Fig.3 is a view in elevation of a modification;

Fig. i is a view-in elevation'of a'further modification; and,

Fig. 5 is a view in elevation'of'still a'further modification.

Similar reference characters indicate corresponding parts throughout the several views of the drawings. The label strip is illustrated as peeled away in each of the above figures of the drawings.

Referring to the drawings, Fig. 1 shows a composite web I consisting of a web 3 of a special open-mesh fabric peculiar to this invention, and a paper label strip 5. The web 3, as illustrated in Fig. 1, is a plain weave open-mesh fabric, i. e., it has a fabric pattern in which each filler yarn passes alternately over and under a warp yarn, and each warp yarn passes alternately over and under a filler yarn. However, in accordance with this invention, the open-mesh fabric web 3 is modified over the conventional plain open-mesh weave and has a central warpwise or longitudinal band, generally designated I, wherein each Warp Other features'will be inpart weight than all the filler yarns l3.

yarns ll and filler yarns l3 are of the same.

. 2", yarn 9 is of substantially lesser weight-than the other warpyarns I in those longitudinal sections of the fabric between the band land the. edge of the fabric, and also of substantially lesser The. warp Weight. Figs. 1 and 2 illustrate thecontrast in weight as between yarns Son the one hand and yarns H and ld-onthe-other in' showing the light weight warp yarns 9 as light lines and the heavier weight warp-yarns-H and filler yarns l3 as heavy lines. The label strip tl, which maybe pre-printed or not, has-a width corresponding to the width of band i and is adhesively secured to Web 3 overthebandl throughoutthe length of the web. It is preferred that awate'r-resistant adhesive be used.

Open-mesh bag material: is customarily woven from paper yarn, usually wet-strength paper yarn, such yarn being made by spinning narrow ribbons of paper, such as kraft paper into yarn, the yarn being made water-resistant by chemical treatment. Carrying this invention into eifect, it is preferred thatweb 3bewoven of such paper yarn. The lighter weight warp yarns 9 may be made of the same weight-of paper as the-heavier weight warp yarns -l l and filler yarns- I3, but spun from narrower ribbons of such paper than the latter. Or the lighter Weight warp yarns 9 may be made of a lighter weight'paper than the heavier weight yarns -H and iii-being spun from ribbons ofthe same width as the latter,

The composite-web?! is'cut on lines indicated at l5fin Fig. linto rectangular bag blanks havlngatwice the width of the bags to be produced.

Each. blankis folded upon itself. one. central fold ll extending transversely of the blank to bring the marginal edges of the blank together, and the folded blank is seamed on one side extending from the fold as indicated at [9 in Fig. 2 to form the bag bottom and at a side opposite the fold as indicated at 2| to form a side seam and complete the formation of the bag. The blanks may initially be folded with the label strip on the outside, or may be initially folded with the label strip on the inside. In the latter case, the bags are turned after seaming. It will be seen that in the finished bag, the band i and the label strip 5 covering the band encircles the bag girthwise centered heightwise of the bag, the ends of the label strip being caught in the Side seam 2 l Fig. 3 illustrates a modification which is the same as the Fig. 2 bag except that the Fig. 3 bag, designated 20, comprises a body of openmesh leno fabric having a band 23 corresponding use of lighter weight warp yarns.

to the band I of Fig. 2 wherein each warp yarn 25 is of substantially lesser weight than the other warp yarns 21 in the longitudinal sections of the fabric between the band 23 and the edges of the fabric and all the filler yarns 29.

Fig. 4 illustrates a further modification which is the same as the Fig. 2 bag except that the Fig. 4 bag, designated 3|, is made of open-mesh fabric woven with a plain weave central warpwise band 33 wherein each warp yarn 35 is of substantially lesser weight than the remaining warp yarns in the longitudinal sections of the fabric between the band 33 and the edges of the fabric and the filler yarns, and wherein the fabric is woven with a leno weave in the longitudinal sections of the fabric between the band 33 and the edges of the fabric. 1

Fig. illustrates a further modification which is the same as the Fig. 2 bag except that the Fig. 5 bag, designated Al, is made of open-mesh fabric woven with a central warpwise leno woven band 43 with plain weave warpwise sections 45 in the areas on opposite sides of the band. Again, the warp yarns 4! in the band are of lesser weight than the remaining warp yarns and the filler yarns.

In each of the illustrated forms of the invention, the use of lighter weight warp yarns in the area lying under the label strip 5 results in a considerable savin in cost, without any sacrifice of strength, inasmuch as the label strip adds strength to that portion of the fabric which would otherwise be relatively weak due to the Also, as to the manufacture of bags which are turned, the bag-turning operation is facilitated by having lighter weight yarns under the label strip, because this offsets to some extent the stiffening effect of the label strip and makes it easier to turn the bag.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A bag comprising a bag body of open-mesh fabric which is characterized in having been woven so as to have a band wherein each yarn which extends lengthwise of the band is of substantially lesser weight than the remainder of the yarns of the fabric, and a label strip having 4 a width corresponding to the width of said band peripherally encircling the bag body on the outside thereof over said band and adhesively secured thereto.

2. A bag comprising a bag body of open-mesh fabric which is characterized in having been woven with warp yarns and filler yarns and with a band extendin in warpwise direction wherein each warp yarn is of substantially lesser weight than the remainder of the warp yarns and all the filler yarns of the fabric, and a label strip having a width corresponding to the width of said band peripherally encircling the bag body on the outside thereof over said band and adhesively secured thereto.

3. A bag as set forth in claim 2 wherein all the warp yarns and filler yarns are paper yarn spun from ribbons of paper, and wherein each one of said warp yarns of lesser weight consists of a ribbon of the same width but lighter weight paper than the remaining yarns.

4. A bag as set forth in claim 2 wherein all the warp yarns and filler yarns are paper yarn spun from ribbons of paper and wherein each one Of said warp yarns of lesser weight consists of a ribbon of narrower width but the same weight of paper as the remaining yarns.

5. A bag as set forth in claim 2 wherein the fabric is a plain weave open-mesh fabric throughout.

6. A bag as set forth in claim 2 wherein the fabric is a leno weave open-mesh fabric throughout.

7. A bag as set forth in claim 2 wherein the fabric has a plain weave in the band and a leno weave elsewhere.

8. A bag as set forth in claim 2 wherein the fabric has a leno weave in the band and a plain weave elsewhere.
