Patented Nov. It), 1936 PATENT OFFICE MACHINE FOR- MAKING HANDLE!) SHOPPING BAGS Hal-ford K. Steen, Newburgh, N. Y. Application November 5, 1935, Serial No. 48,277
6 Claims. (Cl. 93-8) My invention relates to a machine for making paper bags and the like, and more particularly to a machine for making what is known in the trade as shopping bags or handled shopping bags, which have the handles attached thereto and which comprise a bag fabricated from kraft paper or other suitable material and to which cord handles made from twisted paper or the like are permanently attached during the process of forming the bag from the paper Web.
The machine herein described and claimed is suitable for carrying out the steps of my method for making handled shopping bags such as are described in United States Patent No. 1,799,072,]
issued to me on March 31, 1931; and in'my application for patent Serial No. 33,553, filed on July 2'7, 1935.
In the design of this bag making machine herewith shown, I have not included either a printing press for marking the web, or the partly made bags, or the bottom forming end of the machine, as these devices are well known in shopping bags by first making the bag and then attaching handles thereto by either wire staples, rivets passing through a card-board reinforcing pad under the turned in top or by threading the handle cord through holes formed in the bag,
around the bottom or by uing the handles between the bag and its turned in top, or the turned in top and a patch, all of which requires several different operations and handling that causes the finished product to be too high in cost.
To overcome these objections and to provides. bag that will be cheap, durable, eflicient and pleasing in appearance, and yet have great strength in the attachment of the handles, I have devised a machine in which the web or bag blanks are formed into tubes in the usual way, but during this process the webhas attached thereto a pair of suitable handles of cord or the like which are also formed in the same machine as well as the attaching patches; the tubes with the handles attached either being finished in the same machine or in a separate machine as desired.
It has also been found that, in the present method of making handled shopping bags owing to the means employed for attaching the handles 5 to the web, that when the bags are folded for baling for shipment, the handles, being superimposed one upon the other, will build up in thickness thus making a bulky bale and containing too few bags. 10
I have therefore provided against these condi- I tions by so locating, forming and attaching the handles to the web or blank that when the same is tubed and folded the handles will nest one within the other thus presenting only one thick- 5 ness of handle material which is about equal to the thickness of the folded bottom of the bag, so that the finished bags will bale in an even and compact manner.
I have also provided means whereby in place of attaching the handles to the web by long pieces of reinforcing material between which and the web the handles are held by an adhesive, I employ short pieces of reinforcing material in the form of patches, between which and the web, the handles are secured, thus creating a great saving in material and labor.
The machine is also designed so that bags of different widths can be made thereon, and the handles located with respect to the width of the web so that they will nest when the bag is folded.
This being accomplished by constructing the a patch, handle making and attaching devices in a pair or two units, one of the units being stationary on the frame of the machine and the other having transverse adjustment so that the center distance between these two units can be varied to place the handles upon the web in the proper relation with the web and with each other in accordance with the width of the web, and
it will be noted that in the detailed description of the machine Ihave only described one of these units as the other is a duplicate except that the handle is of a different width so that it will nest with the other handle.
The machine is also provided with means whereby the open end of the bag from which the handles project may be either of single thickness, or provided with an extending flange which may be folded inwardly and either pasted down or left loose.
The objects of the invention are to provide a machine automatic in its action, and in which both the patches and handles may be formed 66 from raw stock, assembled and attached to'the web or bag blank during the process of forming the web into a bag.
Another object of the invention is to provide a machine of this kind having few parts, adjustable for different sizes of bags within its limits, and having great speed of operation.
Another object of the invention is to provide a device for forming handles from cord and attaching the formed handles to either a web or bag blanks, and which may be used as a separate machine, an attachment for a bag making machine or incorporated into a complete machine for making the entire bag.
With these and other objects in view, my invention consists in certain novel construction and combination of parts as will hereinafter be fully described and claimed and illustrated in the 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. 7
In all of the drawings some of the parts are not shown, and other parts are shown in section to eliminate confusion, but the omitted parts will be found upon other of the views, also the main.
drive of the machine and some of the driving or operating means employed for the different parts have been omitted as confusing, as these drives are all well known and comprise the usual gears, sprockets, chains, etc., used in this type of machine, and are all driven from the main drive.

Figure 14 shows a detail of the slit cutting knife and its roller. I
Referring to Figure 1, I have shown one side of the main frame of a machine composed of the paper feeding end I0, and the finishing end ll, of a. standard bag making machine, and I have extended apart these two ends ID and H and mounted therebetween two side frames l2, which are formed near their upper edges with the transverse bearings for the braces i3 and I4, upon which are mounted the upper frames l5, which are four in number arranged in pairs to form two units, one unit being permanently secured on the brace rods [3 and I4, while the other unit may be adjusted thereon to vary the center distance between the units for the proper spacing of the handles upon the web.
The supply or stock roll of bag paper i8, is mounted in the usual way on a rod ll rotatably mounted in the bearings i8, and the paper in the form of a web I6 is carried past the two rollers l9 and 20, the rollers 2| and 22 and under the relieved roller 23, and thence between the rollers 24 and 25; 26 and 21, to the handle and patch attaching devices and over the rollers 28 and 29 to the tuber 30.
During thetravel of the web l6 between the rollers 20 and 2|, one of its edges is brought into contact with a paste wheel St on the shelf 32 which transfers paste from the pct 33 to the edge of the web, which is subsequently used in the tubing to secure the edges of the web together. .Also during the travel of the web and before it receives the adhesive and patches, it passes between a knife I58 and a cutting block I59 (see Figure 14) where two longitudinal slits 9 and one transverse slit 8 are cut as shown in Figure 13, or only the transverse slit may be out by the knife.
The purpose of the slits is to permit the cut-off knife to be relieved or divided to register with these slits when the web is cut Ofi into bag lengths after the handles have been attached, so that the web will only be cut off each ide of theslits and the handles will remain pro ecting from the cut edge, for if the cut-oif knife were not relieved,
the handles would be cut oil. from the web with the bag length.
Each of the handles and patch forming and attaching units being the same except of the size and width of the handle it is only deemed necessary to explain one of them in detail, which is as follows.
Each unit is composed of two side frames l5 which are spaced apart in parallel relation and which have secured thereto a water tank 3|; a handle former 35; a patch cut-oil. and a patch and handle transfer device I22; a paste pot 36, and a paster to apply the paste to the traveling web.
The upper part of one of these units is shown in detail in Figure 2; one side I5 being removed and the shafts and rollers and water tank being shown in section for clearness.
The water supply tank 34 has rotatably mounted in its lower end a shaft 38 carrying a roller 39 and a pair of arms'lll; the lower ends of the arms 40 carrying a moistening roll 4|, relieved in the center and rotating in a water pan 42 which is supplied with water from the tank 34 by a tube 43 and its level maintained by an overflow fl. This moistening roll 4i has a swing.
' ing movement to and from the patch imparted to it by a roller 45 mounted on one of the arms 40 in rolling contact with a cam 46 secured on the shaft 4.
The coating surfaces of this moistening roll 4I also have longitudinal grooves I, so located in respect, to the diameter of the roll M and the length of the patch that the dry adhesive 63 on the patch material is not moistened where the cut-off is to take place, as the out should be in the dry material. The coating surfaces of the roll 4| only come into contact with a portion of the gummed surfaces of the patch material and not in contact with the bare material.
The stock paper material 60 fromwhich the patches are made comprises a roll of narrow paper formed with tworows of spaced apart parallel dry adhesive 63. This patch material 60 is mounted on a rod 6| rotatably mounted in the bearings 62 on the frame I5, and this patch material 60 passes under the roller 53 and over and under some of the other rollers to the feeding rollers 50 and 5i which pull the material from the stock roll 60.
The patch material is thus carried to a pair of cut-off rollers 48 and 49, one of which is provided with the usual paper cut-off knife 61 in registry with a slot or pad 5 in the-roller 49 for severing a patch length from the stock and causing the patch to travel through the rollers 48 and 49 where the end is caught by a pair of spaced pins I25 mounted in the transfer drum I22 and projecting from its raised surface I23 and passing through grooves formed in the frame member I0; the patch being impaled upon these pins I25 on the drum I 22 which is mounted on the shaft 56, and its diameter being such that its raised surface I23 will support the patch with its moist adhesive surface upward and exposed to receive the handle and retain it until transferred to the web.
The water applying roll 4I is rotated by a gear 64 secured on a shaft 65 which is driven by the gear 66 on the roller shaft 38, which is rotated from the main drive of the machine, and it may here be stated that many of the drives for the different shafts and rollers have not been shown in the drawings for the sake of clearness and as they are of the usual type and do not enter into the invention.
In Figures 4, 5, 8 and 9, the handle former and applicator are shown in detail and comprise a member or bracket I0 mounted on the frames I5 and formed with'an upperbearing or bearings II within which is mounted a rocker-shaft I2, which is rocked by the action of an arm 8I secured to one end thereof and connected by a link 14 in an adjustable manner as at I5 to' a rocker-arm 16 which is pivoted to a stud 11 in one of the frames I5; the lower end of this rocker-arm I6 is provided with a roller I8 in rolling contact with a cam I9 secured on a shaft rotatably mounted in the frame I5.
To the shaft I2 is also secured anva'rm I3 to which is pivoted a yoke 82 and a second yoke 83, the purpose of which will be described. in detail later.
An arm I5I is secured to the shaft 12 and has secured to its outer end one end of a spring I52 the other end of which is secured to some point on-the frame I5, and this spring I52 forces the handle former III' downward and gives it the power with which to form the handle and e the formed handle I01 thereon.
also retains the roller I8 in contact with the cam I9.
The member T0is provided with the two aligned cord guide tubes 86 and 81 through which the cord for the handles travels; and secured to one side of the frame I5 is a member 68 (see Figures 8 and 9) and upon which are rotatably mounted several transverse shafts which will be explained in detail hereafter; one being a drive shaft 93 which is rotated by a gear 94 in mesh witha gear 95 on the shaft 91 which is in turn driven by a sprocket 97 and chain from a suitable rotating shaft.
Mounted on the shafts 89 and 9| are the cord feed rollers 98 and 99 which are formed with the ers 98 and 99 the cord IN is fed to the combined feed and cord cut-off rollers I03 and I04 which are mounted on the shafts 9| and 92 and shown in detail in Figure 10 of the drawings; the roller I03 having a cut-off angular knife I05 set therein and registering with a recess or pad I06 in. the roller I04; the circumference of the roller I03 being equal to the length of cord required for a handle, and that of the roller I04 being one half that length; it being understood that in one of the units the handle piece is slightly longer than inthe other unit as the finished handles are of different widths sothat whentattached to the web, they will nest one within the other.
The drive shaft 93 has secured on its forward end a gear I08 which is in mesh with and rotates the two gears I09 and II 0 which are secured on the shafts 89 and 9|, both being rotated in the same direction as are also the rollers 98 and I03; the rollers 99 and I04 are also gear driven.
} The cord IN is thus fed through the tubes 86 and 81 and over a bridge plate II5 which is slidably mounted in the-member I0 and located over the handle die I I 2 in said member and under the handle former II I which is attached tothe yoke 82 by the rod II4 which gives it vertical movement in the guideways in said member I0.
This bridge plate H5 is for temporarily supporting the handle piece I 01 in the die I I2 until the former I II is brought down to force the blank .I0I through the die II 2 to form the handle; the
bridge plate I I5 being reciprocated in the member I0 by being pivoted as at III to the bell-crank- II8 which is pivoted as at II9 to the member I0; said bell-crank I I8 being pivoted as at I20 to a rod I2I which is connected to the yoke 83 and which has length adjustment, so that as the arm I3 is swung downward as shown in Figure 5, the bridge plate I I5 will be receded and the former plate I I will force the handle blank I0'I downward carrying the severed ends thereof free from the tubes 86 and 81.
Mounted below the handle former on a shaft 56 is a transfer drum I22 which is provided with a raised surface or portion I28 formed with two parallel annular grooves I24 spaced apart the proper distance to receive the side portions of the handle I0'l (the spacing of these grooves upon the two drums being different so that the handles will be ofdifl'erent width and nest when attached to the web) and adjacent to the forward end of the raisedportion I23 and in the same are secured the two spurs I25 which engage with and pull the patch I26 from the stock material 60 after it is severed by the knife 81; thepatch I26 being supported and carried upon this raised portion I23 with the moistened adhesive upward to receive Just in advance of this raised portion I23 on the drum I22 are mounted two handle engaging pins I21 which project through the wall of the drum I22, being mounted upon the arms I30 which are secured on a shaft I3 I which is mounted in the bearings I32 within said drum I22, and to which is imparted a rocking movement by a cam I33 secured to the frame I5, in such a manner that during a portion of the rotation of the drum I22, these pins I21 vwill project above the surface of the drum and for the remainder of the rotation they will be receded within the drum; they being in their projecting position to engage with the formed handle I01 and carry it from the die and placing it upon the adhesive surface of the patch and transfer both the handle and the patch to the web, after which they recede into the drum, which then moves forward carrying the patch and handle downward between the raised portion I23 of the drum I22 and a guide plate I28 which is attached to the member I and which is formed to conform to the drum I22 and provided with annular grooves to accommodate the handles I01 and the pins I21, thus guiding the passage of the patch and handle from the transfer device to the web.
Referring to Figures 4, 6 and '7; mounted adja cent to the handle former III and also upon the frame I is a paste pct 36 which is provided with a paste roller I35 rotatably mounted in the lower end thereof on a shaft I36, and below this paste pct 36 in the frame I5 is a shaft 80 upon which is mounted a paste transfer device I38 which has two raised paste applicators I39 in annular relation thereto and two transfer raised applicators III); the surfaces of all of which are serrated to pick up the paste from the roller I35 and transfer it by contact to the surface of the traveling web as it passes over the roller Ill on the shaft I3; the paste being deposited upon the local surfaces as shown in Figure 7.
The bag web IS with these gummed surfaces I43 and I now travels over the roller Ill in the frame I5, and due to the rate of speed travel of the web and the timing of the rotation of the drum I22, the handle III! and its patch I28 will be brought into registry with the gummed surfaces I" and I on the web I8 and be deposited thereon where they may be pressed between other rollers to complete their adhesion.
