' Albert Butterfield, Middletown, 0h10, 'aligner to Advance Bag and Paper Company, Incorporated, Bostommacorporationofllhine Application :ne lz, 1m, smal No. su 44a s claims. (ci. ss-ss) This application relates to a method of makare clinched in the double-thick zones. `At lthe ing bags of the kind popularly known as shoplower end these'doublc-thick zones are' foldedping bags. Buch bags'are usually made of tough, into the structure that forms thebottom ofthe strong paper, and while 'throughout this applibag, see Fig. 1, and finally 4pasted together in g cation for a patent I shall refer to them as overlapping relationship, as in'Fig.-3, producing no paper bags, it is not to be understood that other a' structure of remarkable'strength. A material may not be used in their manufacture. I shall now describe a portioniof the bag- A particular feature of Vthis bag resides in. making machine which Imayuse in carrying its being strengthened by a broadvertical zone out my method o! .making bags, referring to extending down the center of its front and rear Figs. 4 and 5'. Inasmuch as Pigs. 4 and `5 are as wall, wherein the paper is of double-thickness'. diagrammatic I l'shall refrain from describing 'I'he handles for carrying the bag are secured structural details of the machine, assuming that in these zones and the zones continue down into these will be understood. j the folds which constitute the bottom of the A roll or webof paper, A, ismounted at 20. bag, thereby giving the bag great strength.l My Paper from this web is guided by a roller 21 7o invention resides in a method of making bags to a uniting roller 22, around which the web is. of this type. Y carried and from which it runs to an idler roller Referring now to the drawings. 23. Mounted adjacent to the roller 22 is a Fig. 1 is an elevational view of one of these paste-applying device. whereby the outer. sur-v bags, which is finished save that Athe bottom face of the web is served with paste as it lrounds 75 1s only partially folded and the handles are yet the roller 22, as will be more fully explained to be attached; presently. A
Fig. 2 is a tube made from two pieces of A second roll or web of Peper. B. is mounted paper, these pieces of paper being pasted toat 25. Paper from this web is guided by a roller gether with wide lseams inthe middle of the 26 across the rollel 22, and it 1200 rims 1*0 the 80 front and back walls of the bag, which makes idler 23. Referring to Fig. 5 lt Will be seen that 9 a substantial part of the iront and back double; the rolls of paper. A end B respectively. are Fig. 3 shows a complete bag; ofi-set withreference to each other, but overlap Fig. d is a portion of a side elevation of a a distance equal to the width of the doublemachine that I may employ in the practice thick zones 11 of the bag. The paste-applying a5 of my method of making these bags, and device previously referred to comprises a pan i Fig. 5 is an end elevation of @machined containing Peste, and a series of paste- Figs. 4 and 5 are principally diagrammatic. ailfwheelriiymese Wheels dil) into'the I shall now' describe the bag.' with the assistpaste in the pan 2'1 and lsuitable-meamnetvmf ance of Figs. 1, 2 and 3 of the drawings. Fig. shown, they are pressedagainst the web A as it v90 2 illustrates the body 10 of the bag, which comrounds the roller 22, thereby applying paste to prises two similar halves, A and B. It will be the paper in this overlapping zone. When the noticed that the parts A and B overlap and are web B comes in contact with vthe paste-coated pasted together to form a broad-zone 11- of surface of A the webs are united, pasted to' 40 double thickness in the vmiddle of the front and gether, and together they round the roller 23 95 back. In Fig. 1 the upper edge of the body has and thereafter round the roller 24 as a unit. been folded inward at 12, forming ahem, and From the roller 24 the combined webs pass to the lower end of the body or tube 10 has been an ordinary bag-making machine, which is not partially folded to form the bottom of the bag, shown. f shown complete in Fig. 3. Finally, handles v The portion of the bag-making machine not 10o 13-l3, made of `heavy cord, are secured to' the shown being old and well known in the art it is upper end of the bag, the ends of the cords deemed unnecessary to illustrate or describe it. being tucked into holes 14-14 that are pierced It will therefore suillce to sayl that it contains near the edges of the double-thick zones 10 durmeans whereby the combined webs A and B are ing the process of making the bag. drawn around the roller 24 and into the mech- 105 As will be readily understood, the doubleanism for making the bags. Itisobvious therethick zones 11 add very much to the strength of fore that the webs are under considerable tenthe bag. At the upper end the double-thick sion from the time they leave their respective zones are folded into the hem, and the handles rolls A and B. 'This tension presses the over- 13-13 are secured io the bag by staples that lapping thickness Aof web together as the web is 110 'freeedgesofthewebA-Bwithalapseamof the samefwidth as that which Joins the webs A andB. Thisstepbeginswithapplyingaxone ofpastetothefreeedgeofthewebAasit rounds the roller 24. For this purpose I employ a second paste-applying devicev 30, similar to the one previously described. This is contiguous to the roller 24 and its wheels 28 apply' pastetothewebAinthemannerdescribed.
Next each of webs A and I B is folded longitudinally with a fold 'intermediate its respective edges, the edge of web A being kept outside the edge of web IB,v thereby bringing the pastebearing surface of web A into contact with thesurface of web B, forming a second seam having a widthequal to the width of zones 11.

Various means may be employed in complet- 'ing the bag, including doing it by hand. But I prefer-to employ an ordinary.bagmaking machine. It is' not essential that the paste be applied in a series' of narrow stripes, for if desired it may be applied in a single stripe co-extensive 1 have mentioned staples as a means for securing the handlesto the'bags, but other means may be employed, cement for instance.
I claim:
l. The method of making bags. 'which method comprises pulling a web oi' paper past a given point, 'simultaneously applying adhesive to ai broad longitudinal zone of said web, beginning at one edge, pulling a second web of like paper past said point in parallelism with and overlapping the adhesive-carrying zone of the rst web, joining said webs; applying a broad longitudinal zone of adhesive to the free edge and on the same side of the ilr'st web as before, folding both webs longitudinally intermediate their respective edges and `uniting said adhesive-carrying free edge oi.' the iirst web to the free edge of the second web,A thereby forming said webs into a tube. g n V 2.
