Jan. 20, 1959 R. P. PE'RRY WOVEN WEBS Filed Aug. 9, 1957 United States Patent O ale WOVEN WEBS Ray P. Perry, La Due, Mo., assignorto Bemis Bro. Bag
Company, St. Louis, Mo., a corporation of Missouri Application August 9, 1957, Serial No. 677,321 6 claims. (cl. 139-383) fabric; and the provision of a fabric of this class wherein v the draw closure member takes the place of and renders superfiuous the selvage-forming warps such as have heretofore been used in open-mesh draw closure bag fabric, thereby reducing the amount of yarn in the fabric. Other objects and features will be in part apparent and in part pointed out hereinafter.
The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.
In the accompanying drawings, in which several of various possible embodiments of the invention are illustrated,
Fig. l is a view in elevation of a bag made from a fabric of this invention, with parts broken away;
Fig. 2 is a plan view of Fg. l;
Fig. 3 is an enlarged Vertical section taken on line 3-3 of Figs. 1 and 2; and,
Figs. 4 and 5 are fragmentary views illustrating modifications.
Corresponding reference characters indicate correponding parts throughout the several views of the drawings.
Referring to the drawings, Figs. 1-3 illustrate a bag 1 which is made from a length of woven open-mesh fabric 3 of this invention. This fabric, as illustrated, is a leno-woven open-mesh fabric having paired warp yarns 5 and single filling yarns 7. The warpyarns 5 are spaced transversely of the fabric and the filling yarns 7 are spaced lengthwise of the fabric. The Warp yarns and filler yarns may be twisted paper yarns such as conventionally used in weaving open-mesh bag fabric, or
any other suitable type of yarn. Although shown as a leno-woven fabric, the fabric may be of a suitable weave other than a leno weave.
In accordance with this invention, a continuous draw closure member 9 is woven into the fabric 3 at one edge of the fabric and lying outward of the outermost pair of Warp yarns of the fabric (these warp yarns being specially designated 5a), with all the loops 11 of the filling yarns 7 at this edge of the fabric extending out beyond the outermost pair of Warp yarns 5a and surrounding the draw closure member 9. As shown best in Figs. 1 and 3, the draw closure member 9 is a draw tape, and more particularly a folded raw-edged fabric draw tape of a type such as is shown in Scruggs U. S. Patent 2,S57,5l7, dated June 19, 1951. It could be a draw GQrd, rather than a tape. The term draw closure memp ,8`69,589 Ptented Jan.` 20, 1959 t ice ber is intended to be generic to draw tapes (whether folded or not), draw cords, and any other type of member for shirring the margin of the fabric.
In forming the bag 1, the length of open-mesh fabric 3 which includes the draw tape 9 is folded in half on fold line 13 extending transversely of the fabric. the edges of the folded length of fabric opposite the fold and opposite the margins including the`draw closure member are stitched together to form a side seam 15 and a bottom seam 17, as will be readily understood in the art. In the completed bag, the draw' closure member 9 extends girthwise of the bag at the month of the bag within the filling yarn loops 11. To close the bag, the member 9 may be grasped at the very top of the bag between any two adjacent filling yarn loops and pulled to shirr the fabric at the mouth of the bag. This type of operation is simpler than that required where the draw closure member is not readily accessible for grasping at the very top of the bag. Also, the construction is such that the draw closure member 9 takes the place of the extra selvage-forming Warp yarns such as have heretofore been used and saves on the cost of the fabric. In this respect, it will be noted that the draw closure member 9 itself constitutes a selvage warp for the loops 11.
Fig. 4 illustrates a modification in which every other loop of the filling yarn (instead of every loop) extends out beyond the outermost Warp yarn and surrounds the draw closure member 9. In this case, the draw closure member forms a selvage Warp only for these loops, which are designated 11. The remainder of the filling yarn loops, which are designated 21, surround the outermost warp yarn. In order to form a selvage for these loops 21, the outermost warp yarn is included in a group of extra selvage-forming warps, such as indicated at 23. While extra selvage-forming warp yarns are needed in this case, in some instances the disadvantage of this may be offset by the desirability of having the double distance between the loops 11 that surround the draw closure member. i
Fig. 5 illustrates a modification of Fig. 4 in which every third loop 11 (instead of every second loop) extends out beyond the outermost Warp yarn and surrounds the draw closure member 9. In this case, between adjacent loops 11, there are two loops 21.
In view of the above, it will be seen thatVV the several objects of the invention are achieved and other advantageous results attained.
As various changes could be made in 'the above constructions without departing from the scope of the in-' vention, 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:
l. Woven open-mosh fabric for making draw closure bags or the like, said fabric having Warp yarns spaced transversely of the fabric and filling yarns spaced length- Wise of the fabric and being characterized. in that a continuous draw closure member is woven into the fabric at one edge thcreof and lying outward of the outermost warp yarn of the fabric, loops of the filling yarn extending out beyond the outermost warp yarn and surrounding the draw closure member.
