Filed Nov. 25, 1931 2 Sheets-Sheet l ,4 rra/ewn Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE BAG Application November 23, 1931 Serial No. 576,807
Claims.
This invention relates generally to bags and material for making same, and more specifically to relatively small bags which are formed of woven strands of material that are widely sepa- 5 rated to produce open mesh, woven fabric, the predominant objects of the invention being to improve the material of which the improved bags are made and to improve the construction of said bags, so that the strength and durability of the bags is increased.
Prior to this invention bags of the type refererd to above were made in various ways, and until the present constructionwas devised and reduced to practice none of the bags were entirely satisfactory in certain particulars. For instance, one construction heretofore followed comprised cutting the fabric of which the bag was formed so that the real selvage of the bagforming fabric was at the mouth of the bag.
This bag construction involved also providing the bag-forming fabric with an ordinary false or paten selvage at the bottom of the bag which was intended to prevent raveling of the fabric and served to give additional body to the fabric at the bottom seam of the bag.
It was found in the use of a bag constructed as just described that the ordinary false or patent selvage at the bottom of the bag was not secure enough to prevent the bottom seam of the bag from pulling out, and to overcome this defect the expedient was adopted of folding the bag forming material at the bottom of the bag to provide a folded over seam. This arrangement was eventually rejected as undesirable because it made necessary the use of addition material, and the procedure was then adopted of providing a false or paten selvage at the bottom of the bag and applying flexible adhesive to the bunched strands of material which comprised the false or patent selvage so as to secure said strands together and to the strands of the fabric with which they contacted.
This construction was found to solve the problem of eliminating weakness at the bottom seams of the bags, but additional experimentation developed the fact that the same results might be obtained in another manner.
This final development involves cutting the fabric of which the bag is formed so that the real selvage of said fabric is located at the bottom of the bag, and a false or patent selvage is provided at the mouth of the bag which is comprised of bunched strands of material to which a flexible adhesive is applied. By s forming my improved bag it is provided with great strength and durability at its bottom seam, and also the real selvage at the bottom of the bag provides said bag with a smooth appearance as no loose ends of the strands of the fabric are present, as would be the case if a false or patent selvage were employed at the bag bottom. In addition, all necessity for using a piece of fabric of increased dimensions in forming the bag, so as to permit folding the fabric at the bottom of the bag to give the required strength and smooth 5 appearance at that point, is eliminated when the bag is provided with a real selvage at the bottom thereof.
Fig. 1 is a fragmentary view of the improved bag, parts thereof being broken away to conserve 10 space.
Fig, 2 is a section on line 2-2 of Fig. 1.
Fig. 3 is a section on line 3-3 of Fig, 1.
Fig. 4 illustrates a slightly modified form of the invention shown in Fig. 1.
Fig. 5 is a fragmentary view of a web of bagformin fabric.
Fig, 6 is a view of a different web of bag-forming fabric.
In the drawings, wherein are shown for the pur- 3Q pose of illustration, merely, two embodiments of the invention, A designates the material of which the bag is formed, said material being comprised of warp threads at and woof threads b. The threads (1 and b of the material A may be woven in the ordinary manner, or, if desired, said material may be woven in a manner to produce what is known commercially as the leno weave, the mesh of the material in each case being. quite open. The web section of material which I pre- ,0 fer to employ in producing my improved bags is provided with a real selvage S at one of its edges only and, as clearly shown in Figs. 1 and 2, this selvage is located at the b tt m o th ba However, the improved bags may be made of webs of material of other type which will be hereinafter referred to. 7
Located at a point a slight distance inwardly from the edge of the bag-forming material at the mouth A of the bag is a drawstring C, which constitutes a woven strand of the material A. Preferably the drawstring C is distinguishable from the other strands of which the material A is formed. For instance, the drawstring m y be heavier than the other threads, or it may be of a 10s different material, or colored a distinguishing color. Likewise the drawstring may, if desired,
be of a different shape from the other strands of the bag-forming fabric.
At the mouth of the bag the material of which 10 said bag is formed is provided with a false or patent selvage P, which comprises a plurality of woven strands of material that are closely grouped. This false or patent selvage P is made in the usual manner, but because of the loosely woven nature of the fabric A there is some danger that the strands of material which comprise said false or patent selvagemight be pulled out of place in the fabric if steps were not taken to avoid such contingency. apply a suitable flexible adhesive, which is indi cated by dots in Figs. 1 and 2, to said strands of material and in this manner secure said strands of material together and cause them to adhere firmly to the strands of the bag-forming fabric with which they contact. Preferably the adhesive is applied to the strands of material forming the false or patent selvage as the fabric is being woven. Thus the bag-forming fabric is provided with a very durable edge at the mouth of the bag which is capable of withstanding the usage to which the mouth of the bag is subjected and absolutely prevents raveling of the fabric at the location of said false or patent selvage.
In forming my improved bag from a portion of a web of material suitable for making one bag and which is provided with a real selvage at one edge only thereof, said web portion is folded along a center line perpendicularly to its real selvage, the fold forming one side of the bag and the real selvage of the bag-forming material being located at the bottom of the bag, as already explained. The folded web portion is then sewed of scam illustrated in the drawings does not require that the bag be turned, but if other types of seams are employed the bag may be turned to arrange the sewed edges of the bag material within the bag.
In producing the form of bag illustrated in Fig. 1, the drawstring C of the bag is of substantially the same length as the strands of material which extend transversely of the bag. The woven material is then folded as already explained to produce the bag, and the opposite ends of the drawstring will be alined with the ends of the transversely extended strands of said woven material. The edge portions of the woven material at the side edge of the bag where'the seam E is to be located are then folded, turned inwardly, for instance, to produce said seam, and while the stitches D are being introduced into the bag to close the seamed edge of said bag and complete the seam E, the opposite end portions C of the drawstring are maintained free from the seam E. The result of this will be that in the completed bag the end portions C of the drawstring 0 will extend outwardly beyond the seamed edge of the bag so as to permit convenient grasping of the drawstring when it is desired to close the mouth of the bag.
If desired the drawstring may be sewed into the side seam E of the bag, and after the stitches D have been placed in the bag the drawstring may be pulled or cut free of the same. Also, if preferred, the ends of the drawstring may be permitted to remain stitched into the side scam I therefore longitudinally between the spaced false or patof the bag and the mouth of the bag may be closed by pulling the drawstring from the folded side edge of the bag.
When the drawstring is located close to the mouth of the bag the usual method of closing the bag will be to draw up the drawstring and tie the opposite ends together. If desired, however, the drawstring may be arranged a greater distance below the mouth of the bag, and after the bag has been drawn to a closed condition the ends of the drawstring may be wrapped several times around the puckered mouth of the bag. The latter will be the stronger closure because all of the strands b will be engaged by the drawstring, whereas in the case of the first method substantially only one-half of the strands b would be so so engaged.
By providing my improved bag with a real selvage at the bottom seam thereof a very durable bag is provided, as it is at this point that a bag of this type is most likely to fail in use. Also, by locating the real selvage of the bag-forming fabric at the bottom of the bag, said bag is provided with a smooth bottom portion which is entircly free from loose ends of strands of the fabric, and likewise the necessity of folding the fabric (with the resultant wastage of'rnaterial) to provide the bag with a durable bottom portion is eliminated.
Instead of causing the drawstring to be woven with all of the strands of the fabric A which are extended at a right angle with respect thereto, as shown in Fig. 1, I may weave the drawstring in such manner as to skip certain adjacent strands b of the fabric, as shown in Fig. 4. Thus more strands of fabric are provided at the inner side of the drawstring against which said drawstring may act when the mouth of the bag is being drawn to a closed position, whereby the drawstring will very tightly secure the bag in its closed position.
In producing the woven material employed in making my improved bags in small sizes, I preferably weave a web of fabric, as shown in Fig. 5, which is double the width of the section of material necessary to make a bag. This web of material is provided with a real selvage S at its opposite longitudinal edges, and at its approximate transverse center, said web of material is provided with a pair of false or patent selvages A which are provided with the adhesive referred to, said false or patent selvages being extended ent selvages A to produce a pair of web sections, each of which is provided with a real selvage at one longitudinal edge and a false or patent selvage at the opposite longitudinal edge.
Each of the sections of the web of material is then cut into pieces of the proper size and each piece so cut is folded and stitched in the manner already explained to produce a bag.
Another method of procedure is to weave a web tively narrow bag-forming sections of material are produced and the individual bag-forming sections are cut, folded, and stitched, as already explained, to produce the bags. As is apparent from an inspection of Fig. 6, the intermediate bag-forming section (when the web of fabric is of three-section width) is provided with false or patent selvages at its opposite longitudinal edges. Bags made from this section will, of course, have false or patent selvages at the bottoms and mouths thereof, but because of the adhesive forming a part of each of said false or patent selvages, very durable bag structures will be produced. It is obvious that if the web of fabric is of more than three-section Width, there will be a plurality of intermediate sections having false or patent selvages at their opposite longitudinal edges.
The only other similar method of making small bags in accordance with this invention would be to weave webs of material of the width of one of the sections of material necessary to produce a bag. Each of these webs would be provided with a real selvage at each longitudinal edge thereof, and, of course, bags formed from said webs would have real selvages at the bottoms and mouths thereof. While this method would result in the production of very durable bags, it could not be employed, as manufacture of bags in accordance therewith would be economically impractical.
While I have stated herein that I preferably apply the adhesive material to the strands which produce the false or patent selvage while the fabric is being woven, I wish it to be understood that if found to be desirable I may vary this procedure and apply the adhesive material to the strands referred to either before or after the weaving operations take place.
I claim:
1. A bag formed of woven open mesh fabric and having an unselvaged edge, a group of relatively closely adjacent strands interwoven with the strands of the fabric to form a false selvage at the said unselvaged edge, and a binder material applied to said strand group to secure the several strands thereof together and to the said fabric strands.
2. A bag formed of open mesh woven fabric and having its mouth formed of an unselvaged edge, a group of closely adjacent strands interwoven with the strands of the fabric to form a false selvage at the said unselvaged edge, and a binder material applied to said strand group to secure the several strands thereof together and to the said fabric strands.
3. The bag as set forth in claim 2, wherein the said binder material is in the nature of a flexible adhesive to be applied to the strand group and adjacent portions of the fabric strands during the weaving of the fabric.
4. A bag formed of a sheet of open mesh woven fabric folded upon itself in a manner that its bottom end is formed of joined selvage edge portions and its mouth of an unselvaged edge, a seam closing one side of the bag, a group of closely adjacent strands interwoven with strands of the fabric and arranged parallel to the said unselvaged edge to form a false selvage, and a binder of a flexible adhesive applied to said strand group to secure the several strands thereof together and to the fabric strands.
5. A bag formed of open mesh fabric provided with relatively closely woven strands extending circumferentially of the bag and adjacent the open edge thereof, and adhesive material applied to said close woven strands for securing them together and to the interwoven elements extending transverse thereto to form a selvage.
