Patented June 7, 1932 'D' STATES I LIAM n; KENNEDY, or WESTERN SPRINGS, ILLINOIS BAG CONSTRUCTION Application filed January 23, 1930. SerialNo. 422,744.
r This invention relates to bags of the type wherein a drawstring is provided around the mouth for closing same and has reference more particularly .to the arranging of the drawstring in the edge of a length of material so that the latter may be cut into sections or blanks for making the bags. and each section or blank .will'have extra length of draw- String projecting therefrom to afford external ends which may be readily grasped for drawing the mouth'of the bag closed.
, The principal objects of my invention are, to provide an improved method of maklng :bagsof the type'above referred to; to assemble the draw string in lengths of bag material whichfare subsequently cut into blanks from which the bags are made to arrange the draw string in the edgeof the bag material so that each. bag blank cut therefrom has extra length of draw string for. external projecting ends; to insure a protruding of the ends of the draw string from each; blank and thus facilitate further construction of. the bag; to anchor the draw string of the bags so as to prevent accidental pulling out thereof without such anchoring interfering with the intended function and operation of the draw string; to accomplish the anchoring as the draw string is being assembled in the bag material; and in general to simplify, improve and facilitate the construction of bags of the type above referred to. r
On the drawing:
, 1 F ig. 1 is a perspectiveview of a bag made accordance With my invention; Rig. .2 is a plan v ew of a length of bag fabric from which the bag blanks are .cut,
and shows the manner of assembling the draw string in the edgethereof; and p F 3 is an enlarged fragmentary View, partly insection, of an edge portion of a ba anchoring the draw string to prevent pulling Referring tothedrawing in which I have ,for the purpose of illustration shownmy in- .rentieninconnection with emai ing bagh vnad ress tag attheclo ed end, a h ugh it isto understood that the invention is "string. hem along not limited to this particular-type of bag, Fig. 1 shows the completed bag which consists of a piece of fabric which is folded along the edge 1 forming the two sides 2 and 3 which are stitched together along the edges 4 and 5, the bag being turned inside. out after the stitching so that the seams come on the inside of the bag. In the present form of bag an address tag 6 is attached along the lower edge 5, being inserted and stitched between the edges in the usual manner as the lower edges 5 of the bag are being stitched together.
A hem is formed around the mouth of the bag byturning in the edge portion 7 and stitching at 8 so as to provide a tubular pocket 9 aroundthe mouth inwhich is located a draw string 10 having ends projecting at the edge 4 of the bag which may be readily grasped for drawing and tying the mouth of the bag closed.
The ends of the draw string 10 are usually left loose so that they may be readily tied together to hold the mouth of the bag closed when the bag is used, and consequently, unless the drawstring is fastened to the bag it islikely to be accidentally pulled out of the tubular pocket 9 thus occasioning considerable loss of time in replacing the stringer expense of discarding the bags. To avoid this objectionable feature I anchor my draw string preferably at or near the folded edge 1 so that it cannot bepulled out of the tubular pocket 9,. and at the same time does not interfere with the use of the bag and draw string, this anchoring being effected according to my present invention. in the operation of forming the hem and installing the draw string in the edge of the bag material. This is conveniently accomplished by providing a loop 11, in the draw string at or near the place g .wherethe fold 1 occurs in the finished bag and f l-ank showing the arrangement of the draw stringinthe edge thereof and the method of r the folded edge forms the draw a To make this bag according to my present invention, I take a length of bag material ofa width suitablefor the length of'the bags to be made therefrom and form the'draw the edge as shown atthe top of Fig. 2 by folding over the edge 7 and stitching along the line 8. The draw string is placed in the pocket 9 as the latter is formed, being arranged in the zig-zag or crimped form as shown at 12 so as to provide the extra length required as hereafter indicated and as the draw strin in the crimped form is fed in place the edge? is turned there over and stitched.
The width of the crimped draw string is of course less than the width of the pocket 9 so that the draw string is not caught in the stitching 8 and can in the later construction of the bag be pulled out straight. However, at suitable intervals a longer loop 11 is formed in the crimped draw string, this being located according to the subsequent cutting of the length of material so as to come at or near the fold line 1 of the blanks, and these longer loops 11 are caught by the stitching 8, as shown particularly in Fig. 3, so as to anchor the draw string at these points.
After the length of material is formed with-the hem and crimped draw string 12 therein, it is cut into pieces or blanks of suitable size to make up into individual bags, the lines of cutting being between the places where the longer loops 11 occur; for example, the length of material shown in Fig. 2 is out along the lines A-A into separate pieces. These pieces are then folded along the line 13-13, at or near which the anchored loops 11 occur, and stitched along the bottom and side edges to form bags similar to that of Fig. 1.
The cutting of the length of material into bag blanks, of course, cuts the crimped draw string 12 into lengths which on account of the crimping are sufliciently long to pull out at the edges of the blank and provide the projectin ends 10 which are required in the finished ag. It is to be noted, however, that these out blanks each has the draw string anchored at or near the fold 1 so that it cannot be accidentally pulled out in the further construction or use of the bag.
Furthermore, when the bag blanks are cut from the continuous piece of bag material, it is not sutficient that the hem contain extra length of draw string. The ends must be readily available without fishing for them, so that the draw string may be pulled out to its full length or engaged by mechanism in the further operations of completing the bag. With the draw string arranged in the crimped manner as herein described, this important result occurs, as the severed ends of the draw string at the severed edges of the fabric, by reason of their crimped form, have a springlike action and the ends snap or spring out of the ends of the pocket of the hem as indicated at 13 in Fig. 3, thus permitting the ends to be grasped by hand or mechanical device for pulling out the draw string to its full length. r
With this construction of and method of making up bag material, the making of the bags may be continuous and automatic as long pieces of bag material can be fed to mechanisms which crimp and lay the draw string in place and fold and stitch the hem thereover, and after this is done the length of material may be cut into blanks and readily made up into the finished bags, particularly as the springingout of the ends of the draw string from the blanks insures thatthe draw string ends are available for engagement and manipulation by mechanisms for pulling out and holding same in the further operations of completing the bag.
\Vhile I have shown and described my invention in a preferred form, I am aware that various. changes and modifications may be made without departing from the principles of my invention, the scope of which is to be determined by the appended claims.
I claim as my invention:
1. A blank for making a bag with a draw string around the mouth, said blank consisting of a piece of fabric having a pocket along one edge and a draw string puckeredin the pocket to occupy a length thereof substantially less than the length of the draw string and providing extra length substantially in excess of the length of the pocket.
2. A fabric strip for making bags with a draw string around the mouth of each bag, said strip being of a length to be divided into a plurality-of bag blanks and said striphaving a hem along the edge with a crimped draw string therein of a length substantially greater than the length of the hem.
1 3. A strip ofbag making fabric having a fold along the edge and a cord of a length substantially greater than the length of the fold and formed with a plurality of successively looped portions within the fold to provide extra length for projecting ends.
4. A strip of bag making fabric having a lateral fold, and a cord formed with a plurality of successively looped portions within said fold, said loops extending transversely of said fold. j
5. In an article of manufacture, a fabric strip having a lateral fold, a cord looped transversely in said fold and runningthe entire length thereof, and means for'anchoring said cord atintervals within said fold.
6. In an article of manufacture, a fabric strip having an inwardly turned lateral edge, stitching extending through said edge and the body of the fabric to form a lateral pocket, and a looped cord extending longitudinally through said pocket, certain" of said loops being secured by said stitching.-
