attorney I Patented Apr. 13, 1937 UNITED STATES PATENT OFFICE 2,076,689 snorrmc BAG Hal-ford K. Steen, Newburgh, N. Y. Application July 27, 1935, Serial No. 33,553 4 Claims. (01; eas -s4) This invention relates to .shopping bags made of paper or other suitable material and to the method employed in their manufacture, and constitutes an improvement over that described and claimed in United States. Patent No. 1,799,072 which was issued to me on March 31, 1931, for -a Method of manufacturing shopping bags.

In the above referred to patent, the cord handles were secured to the inside of the bag by 10 an adhesive and a reinforcing strip that extended the entire length of the bag web, from which the tube and bag were formed, and to provide for the extension or projection of the proper portion of the handles to form a grip beyond the upper 15 or open end of the finished bag, the end v of the bag was cut or slotted down for a portion of the length of the handle and was then folded over along a crease which was formed in the making so that this fold could be either pasted to the inside of the bag or left loose to form a flap which could be folded to partly close the bag.

But it has been found that this method of manufacture not only consumes time and uses a greater amount of both the bag stock and the reinforcing material than is necessary, but does not provide such a pleasing appearance or as serviceable a bag as one where the handle projects from an even single thickness of bag material. i 30 To facilitate the bundling or packing of the folded bags in bales for shipment and to prevent the stacked handles from building up in thickness thus taking too much room in the bale, and to give a closer formation adding greatly in the 35 manufacture, especially when a bottomer is used as the stacks of bags in the machine do not have to be replenished so often, I have nested the handles. 7

Also by the nesting of the handles, parts of the 40 machine through or over which the. attached handles have to pass, do not have to be relieved so much thus eliminating the possibility to creep and the machine will thus operate to better advantage. 45 While I have shown and described these handles as being attached to the bag by gummed patches, it is to be understood that they may be attached by other suitable means, such as staples or tied through holes formed inthe web:

50 For this purpose I have added to my above mentioned patent the idea of locating the attached handles to the web in such positions that when the bags are folded, the handles will be nested one within the other so that they will lie 55 side by side and only occupy the thickness of one single handle in the stacking of the bags,' thus saving over 40 per centof the storage and shipping space required for the same number of bags that were made in the old manner. 50 Another object of the invention is to, provide a bag iirwhich the cord handles are secured to the interior thereof by an adhesiv)eapplied to predeterminedlocal surfaceson the web and adapted to receive patches which have received the handles and which are both secured to the web by the adhesive or other suitable means, to form a firm and strong junction.

Another object of the invention is to provide a bag in which the cord handles extend beyond the open end of the bag without having to have 'the end of the bag folded over or formed with a flap.

Another object of the invention 1S5t0 provide a bag in which the cord handles are so located and' attached that when the bag is folded, the handles will nest one within the other to present a single thickness of handle and prevent building up when baled.

With these and other objects in view, my invention consists in certain novel construction and combination of parts as will hereinafter be fully described in the following descriptionand illustrated inthe accompanying drawings which form a part hereof and in which like figures of reference refer to corresponding parts in all of the views, and it. is understood that slight changes may be made without departing from the spirit of the invention.

In carrying out my invention the mechanism required for the various steps and operations may 20, and these patches are carried past the pads 28" be constructed in a single machine, or as a part of a bag making machine of the usual type, or the bags may be taken from my apparatus when in the form of a tube and bottomed and folded in another machine if desired, and in the description and illustrations of this present invention I have embodied my invention in a bag making machine without the bottoming and folding means.

Referring to the drawings:

I have taken the usual bag making machine A travel through the machine is indicated by the broken lines.

From the stock roll ill the web travels past the seam pasting rolls I! where paste is applied to one edge I! to later on hold the web in the form of a tube, and the web next travels past the knife l6 where the two aligned slits 24, which locate the position of the handles iii are made, and if it is desired to form the bag with a flap 11, a crease 26 is now placed in the web by the creaser 25, and from either the slitting knives H5 or the creaser 25 the web is carried past the adhesive pads it which transfer adhesive from the pot H to predetermined local surfaces 16 on the web adjacent to the slits 2| for the reception of the handles i8 and patches i9.

While this is taking place, a pair of cord handles i8 and their attaching patches N are being prepared as follows: A'piece of cord 23 is drawn from the stock roll 21; cut off and formed into the D-shaped handles il.. From the roll of strip,

stock, either plain or gummed, a strip 2i isfed and from this are cut the patches I! by the knife on the roller 32, which either applies moisture or gum to the patches in two parallel stripes 29 T on their surface. 7 7

The transfer roller ll that carries these patches I9 and transfers them to the web II, is provided with the pins II which perforate the patch lfl and carry it along as well as the formedhandles ill upon the patches in the moist contact with the pins 3|.

As the traveling web it reaches the proper gum and in station in the'machine the transfer roller 30 places the gummed patches i9 and the handles it upon the previously gummed local surfaces It on the web, which is then carried throughthe press rollers 22 that press the patches l9 and handles i8 upon the web Ii to form a firm and strong junction. I

From the handle pressing roller 22, the web ii is carried to the usual tube forming device 34 which brings together the edges of the web Ii which are retained by the paste seam I5.

After the bag tube has been formed, it is severed from the web Ii by the cut-off knife 26 which makes a transverse cut I! in aligned relation with the slits 24 if the bag is to be made without a flap ll.

But should it be desiredito form the bag with the flap l1, then when the original slits 2| are made, additional slits are made at right angles thereto in line with the body of the handles l8, or these longitudinal slits may be made without the transverse slits; the web Ii creases at the proper location to form the flap II, the crease 26 acting as a guide in folding the flap II.

The bag tube is now taken to the bottoming device where the bottom is formed, and the bag isfthen folded and baled.

The paste or adhesive rolls l2, l3, and 20 are of the usual type having raised pads l3 and 28 for transferring the paste. from the pot to the web ii, and are provided with the cut-out portions 35.

To provide for the folded bag not building up in thickness in the bale due to the handles i8 stacking one upon the other, I have formed the two handles of slightly different dimensions, and

- have located them both upon the patches and terposed between the patches and the inner surface of the body portion'with their gripping portions projecting from the open end of thebas, and nesting one within other when the bag is folded.

2. As an article: of manufacture, a shopping bag comprising a body portion having an open end and a closed. end and adapted to be folded {when not in use, patches of reinforcing material secured to the inner surface of said bag body adjacent to the open end, handles of different width interposed between said patches and the bag and secured thereto with their grip portions extending from the open end of the bag and adapted to nest with each other to form a single thickness of handle when the bag is in a folded state. 3. As an article {of manufacture, a handled shoppingbag' comprising a body having an' open end and a closed end and adapted to be folded flat forming two sides, patches secured to saidsides adjacent the open end, handles formed with grips and different width body portions, said body portions of the handles interposed between the patches and the-bag and secured to both with the grip portions "extending from the open end of the bag, and nesting one within the other when the bag is folded.
