SPECIFICATION forming part of Letters Patent No. 575,062, dated January 12, 1897.

i. To (LZZ whom it may cancern: Q 3 Be it known that I, ALBERT O. GETTEN, a ilcitizen of the United States, residing at Sandy 3. Hill, in the county of Washington, State of EN'ew York, have invented certain new and iuseful Improvements in Paper-Bag Machines,

of which the following is a specification, refer- T'ence being had to the accompanying draw- .ings, forming a part hereof.

This invention relates more especially to ;the printing of letters, figures, characters, or iornamental or distinctive marks of any char- ;acter whatsoever upon paper bags. Ordi- Efnarily paper bags are printed after they have been finished,which involves a separate opera- '-f tion and a consequent increase in cost. The desirability of printing the paper before the {bags are formed therefrom is obvious, but hitherto there have been certain obstacles or diffiiculties in the way which have rendered this '"impracticable. 1f the roll of paper is printed and dried, so that there shall beno possibility of the-transferrin g of theink from the printed f surface, or offsetting, as it is technically termed, and the paper is then rewound in a roll and brought to the bag-machine, there is inevitably so much change in the length of the paper that in running off a long roll the printed matter and the bags as formed fail to register. It therefore becomes necessary that the printing and the forming of the bag shall be done in one continuous operation without rewinding the paper between the printing and the formation of the bags. Hitherto this has 3 been impracticable on account of the offsetting of the ink from the freshly-printed surface upon the rolls of the bag-machine, quickly causing the blurring and smutchin g of the unprinted surfaces of the bag. Even if the 0 offsetting of the ink upon the rolls of the bagmachine could be overcome, it would still be impracticable, under present methods of manufacture of satchel-bottom bags with bellowsfolded sides, to print upon all sides of the bag because of the practical impossibility of preventing the offsetting between the bellows folds, as thebag after being folded is subjected to great pressure between the rolls of the-machine. I have sought to meet all of these objections and to overcome all of these of any desired construction.

Application filed March 19, 1896. Serial No. 583,881. (No model.)

difficulties, printing the paper and forming the bag in one continuous operation and enabling the printing to be done upon any and every part of the bags surface without any offsetting whatsoever. I have accomplished this result by the means described hereinafter.

In the accompanying drawings, in which I have illustrated an embodiment of myinvention, Figure 1 is a side elevation in outline of a bag printing and forming-machine, only a portion of the bag-forming mechanism being represented. Fig. 2 is a perspective view of a portion of the mechanism shown in Fig. 1 to illustrate more clearly the relations of some of the parts thereof. Fig. 3 is a side elevation in outline of that portion of the bagforming mechanism which completes the folding of the bag and which is not represented in Fig. 1. Fig. 4 is a plan view of a portion of the mechanism represented in Fig. 3. Fig. 5 is a front elevation, partly in section, of some of the parts shown in Fig. 4. Figs. 6, 7, 8, 9, and 10 are detail views representing a bag at various stages of its formation to enable the following description to be more readily understood.

My invention is not concerned with the particular construction of the printing mechanism nor with the particular construction of the bag-formin g mechanism, and my improvements may be employed with any ordinary form of either mechanism. Accordingly I have not sought to represent completely and in detail the construction of either of these mechanisms, but have indicated enough of both to enable my invention to be clearly understood, and I shall not hereinafter refer to the details of construction or'operation of these mechanisms except so far as it may be necessary to explain more clearly the nature and operation of my improvement.

As represented in Fig. 1, the paper to be printed and thereafter to be formed into bags is supplied from a roll A, which may be suitably supported upon or in proximity to the printing mechanism 13, which is represented in said figure as a lZWO'OOlOF-PIlHlJlDg mechanism, although it may be a single colorprinting mechanism or a printing mechanism The said mechanism is set immediately in front of the bagforming mechanism and is. operated therewith by a shaft B, (shown in Figs. 1, 2, and 3,) so that the printed matter for each bag shall be placed upon the web of paper in a position to register exactly with that portion of the web which is thereafterformed by the bag mechanism into a single bag, the shaft being shown as geared to the printing-roll and to one of the forming-rolls. The printing mechanism and the bag mechanism consequently form, virtually, parts of a single machine in which, as will hereinafter more clearly appear, the printing and the formation of the bag are effected in one continuous operation.

It is of course desirable that the freshlyprinted surface of the paper shall be dried as rapidly and as thoroughly as possible before it reaches the bag-forming devices. To accomplish this, it is desirable to extend the path of the paper between the printing meehanism and the first folding devices as much as possible within reasonable limit, for which purpose suitable guide-rolls e, c, and c are provided, over which the paper is led back and forth while its printed surface is subjected to the action of dry and heated air. To supply the air in sufficient volume and in the most effective manner, I prefer to provide an air-distributer of the general form of that represented in Fig. 1, that is to say, of a form which shall correspond with the path of the paper. As represented in Figs. 1. and 2, the distributer C is substantially U -shaped or horseshoe-shaped, embracing the roll 0. It consists of a flat tube of sheet metal, which is perforated, as at c, on the side adjacent to the path of the paper. At a convenient point it has connected thereto a supply-pipe 0 through which the previously dried and heat ed air is forced from any convenient source. As the air issues through the perforations of the distributer it impinges upon the printed surface of the paper, whereby the ink is subjected to the action of the dried and heated air continuously from the time it enters the drier until it leaves the same and is thereby thoroughly dried, so that there is no danger of offsetting upon the rolls of the machine. Nevertheless, even with this precaution taken, there might be offsetting between the folds of the bag if there is printing thereon by reason of the pressure to which the bag is subjected after it is folded.

I will presently describe the provisions which I have made to prevent the oifsettin g of printed matter from one side fold to its opposite. The roll 0 is itself preferablya steamheated roll, so that the paper is dried not only by the hot air, but by contact with a steamheated surface, which makes the paper less hard and brittle.

The provisions above alluded to comprise means for interposing between the opposite side folds a strip of paper which shall receive the offset as the bag passes through the forming devices and can afterward be removed, thereby leaving the bag free from disfiguring offsets or blurs.

In the form of folding devices represented in Figs. 1 and 2 the web of paper passes from a guide-roll (l beneath the former D, which is shown in part only in Fig. 2, and thence between guides d, by which the web is formed into a trough. Next in order upon the frame of the machine are secured the brake-wheels, one of which is shown at E in Figs. 1 and 2, which break or bend inward the sides of the paper trough, making the side or bellows folds e e of the bag. (See Figs. 0, 7, and 8.) From the brake-wheels E E the web of paper passes on between the rolls of the bag-forming mechanism which fix the folds. It is at the time when the side folds are being formed that I introduce the strip which is to receive the offset of the printed matter on such side folds. As a convenient means to feed in the strip at the proper time I secure to the frame of the machine, in proximity to the brakewheel on each side, a bracket F, which sup ports a guide rollerf, the latter projeetin g inward into the folds as it is being formed. Each strip (represented atf'f) is supplied from any convenient source, preferably from a spool or reel which is suitablysupported upon the frame of the machine, the paper being wound thereon in a roll and drawn forward with the web of paper which forms the bag as it progresses through the machine. The strips are severed as each bagis formed and se'vered, and as the bags are delivered from the machine the strips lie within the fold and can thereafter be removed readily.

It may sometimes happen that the ends of the strips above referred to maybe folded in with the bottom of the bag and pasted down unless means are provided to prevent this. Accordingly I have provided means whereby after the preliminary folds of the bottom have been formed, as indicated in Fig. 8, and the strips between the folds have been folded upon themselves at right an gles,whereby their extremities stand out from the folds, as represented in Fig. 9, the ends of said strips are held out during the formation of the final folds, so that they shall not be folded in and pasted down. The means which I prefer for this purpose and their relations to the bagforming devices are represented in Figs. 3, 4, and 5. As the bag passes from between the nipper-roll G and the overlying presserroll g the folds of the bottom are formed in succession by the cooperation of the tuckerblade g, the gripper-r0119, the seam-holder g, the fingers g", the coacher-roll g and the wings g, the coacher-roll being driven. through a gear g and an intermediate gear from a gear 9 on the shaft 9 which carries the cams g for operating the fingers 9". As the mechanism just referred to forms no part of my present invention, it is not necessary herein to describe its arrangement and mode of operation in detail, except to say that the wings g are liable at times to turn in the ends of the strips, so that they shall be caught and pasted down. In order to prevent this, I direct a blast of air through a suitable pipe II against the projecting end of each strip just before and during the action of the wings g and thereby cause such ends to stand out and away from the wings, so that when the bag is completed, as shown in Fig. 10, the ends of the strips shall stand out at right angles, as there shown, whereby the strips can be easilyand completely removed. Any convenient means may be employed for producing the blast of air. I have shown the pipe H as connected to the nozzle of an ordinary bellows h, which is operated by a pitman h and crank it on the shaft g whereby the blast of air is produced only at such times as it is required.

Without further description or explanation it will be understood that the paper is printed in a web and the bag formed therefrom in one continuous operation, that the ink is so thoroughly dried between the printing and the formation of the bag as to prevent offsetting upon the rolls of the machine, and

that by the interposition of the strip between the side folds theoffsetting from one of said side folds to the other is entirely prevented.

It will be obvious that various changes may be made in the details of construction and arrangement of the various devices without departing from the spirit of my invention,and particularly that the invention is in no wise limited by anything herein shown or described as to the character of the printing and bagforming devices.

hat I claim, and desire to secure byLetters Patent, is

1. In a bag-machine, the combination with the former, brake-wheel and pressing-rolls, of a device to introduce a strip between the side folds of the paper.

2. In a machine for forming bags with folded sides, the combination of means to supply a strip of paper and a guide to introduce said strip between the side folds of the web of paper.

3. In a bag-machine provided with means to introduce a strip between the side folds during the formation of the bag,-the combination with the devices for folding'in the bottom of each bag, of an air-blast to direct a current of air against the end of said strip and prevent the same from being folded in with the bottom of the bag.
