6' Claims.
The invention relates to the manufacture by automatic machinery of paper articles such as boxes, envelopes, wrappers, labels and all paper and cardboard products which are color printedand the printing ink rapidly set or fixed immediately prior to manufacturing operations.
This invention relates particularly to the art of high speed, large quantity production of printed paper articles. It is the practice of producers of such articles to use paper or cardboard which has been manufactured according to specification. A usual requirement of such specification is a prescribed amount of moisture which the material must contain. The reason for prescribing a definite moisture content of the paper is that such a requirement facilitates accurate, efficient and fine quality production by permitting the paper to respond properly to printing and fabricating operations. Should the moisture content of the paper be too low, the paper may tend to resist the printing impression, also an insufficient moisture content may result in cracking or breaking of the paper when creasing and folding operations are performed. On the other hand, should the moisture content of the paper be too high, accurate fabrication is rendered very difficult and results in a product which is likely to shrink and become distorted when exposed to atmospheric conditionswhich are not artificially controlled. The moisture content of the'paper is frequently maintained during the period after its manufacture and up until the time for printing and fabricating, by storing the paper in chambers wherein the temperature and the humidity are controlled to prevent addition or reduction of the moisture content of the paper.
In the process of manufacturing printed fabricated articles by a succession of operations, wherein the fabricating operations follow the printing operation and wherein the printing ink must be set or fixed prior to said fabricating operations, it is necessary to apply heat to set the printed ink. Heretofore in the methods of heat setting or fixing the printed ink, the moisture content of the paper has been greatly disturbed, resulting in shrinking of the paper; thus causing faulty register of the printed areas with the fabricating operations and also rendering folding and creasing operations unsatisfactory because of cracking or breaking of the paper. due to its dry condition after the heat drying treatments.
It has not heretofore been possible to produce printed and fabricated articles by a sequence of operations, wherein the printed ink is rapidly set by heat treatment, and yet maintain the moisture content of the paper unchanged throughout the process of manufacture.
The process and the machine hereinafter described involves the use of quick setting printing ink containing a carrying agent which is driven off when the ink is subjected to air having a temperature upward of 180 degrees Fahrenheit. Printing inks of this character become set or condensed when subjected to air of a fairly high temperature, even though the humidity of-said air be very high.
One of the objects of our invention is to produce a method by which printed paper articles may be made from a'web by a succession of operations wherein color printing is effected and the printing ink rapidly set by the application of heat, without changing the moisture content I of the web of paper throughout the process of manufacture.
Another object is to provide a mechanism which will automatically print a web of paper, rapidly set the printing ink by heating means without disturbing the moisture content of the paper and then fabricate the said web.
With said objects in view, and others hereinafter explained, our invention consists in the .'method and machine, substantially as hereinafter described and claimed.

Figure 2 is a plan view of the machine shown in Figure 1.
Figure 3 shows the condition of a section of the paper web as it is operated upon in its passage through the machine.

Similar reference characters indicate simila parts or features in all of the views.
Referring first to Figures 1 and 2, the different parts or members of the machineare mounted on suitable side frames l and 2 connected by crossbars 3 and 4.
Mounted on shaft 5 at the feed end.- of the machine is a roll of paper 6 for supplying the web a which is drawn continuously through the machine by the action of other parts of the machine to be described presently. I
A printing unit is provided for color printing the web a as it is advanced, comprising printing rolls 1 and 8 mounted on shafts 9 and it respectively, said shafts being journalled in. side frames I and 2.
The next unit comprises an oven ll (Figs. 1, 2, 4, 5, and. 6) supported by side frames I and 2. The oven is provided with a vent pipe I2, and air intake openings l3. Openings I4 and I15 are provided to permit passage of the web through said oven. A combustible gas burner It supported by brackets I1 mounted on side frames 2 is provided to heat the oven to a desired temperature.
The dry bulb thermometer I8 (Figs. 4, 5 and 6) mounted within vent pipe l2 automatically causes the controller l9 to operate. The said controller is provided with an adjustment screw 20 which is set to cause the controller to operate when the temperature of the oven varies from the degree of temperature at which the oven is to be maintained. The said controller I9 is electrically connected to modulating valve unit 2| and to an outside source of electric power by means of wires 22, 23 and 24. Combustible gas is supplied from an outside source to supply pipe 25, thence said gas passes through modulating valve unit 2| to as burner I6. A wet bulb thermometer 26 is also mounted within vent pipe I2. The said wet bulb thermometer 26 automatically causes the controller 21 to operate when the wet bulb temperature within said vent pipe varies from a. predetermined wet bulb temperature. Adjustment screw 28 is used to set the degree of the wet bulb temperature at which the said controller 21 shall operate. The said controller 21 is electrically connected to modulating valve unit 29 and to an outside source of electric power by means of wires 30, 3| and 32. Steam is supplied from an outside source to supply pipe 33, thence the steam passes through modulating valve unit 29 to steam jets 34.
The next unit comprises a pair of rolls 35 and v 36 (Figs. 1 and 2) journalled in side frames I and 2, said rolls having peripheral ribs and grooves for adding crease lines I), c, d, and 6 (Figs. 2 and 3) to the web a of the paper as it is advanced through the machine.
Adhesive is applied to the margin ,1; (Fig. 3) of the web a by roll 31 (Figs. 1 and 2) supported by reservoir housing 38 mounted on side frame I.
The next unit comprises folding bars 39 and 40 supported by side frames I and 2 respectively.
The next unit comprises a pair of rolls 4| and 42 (Figs. 1 and 2) journalled in side frames I and 2. The upper roll 4| is provided with knives 43, which cut the folded web into sections it (Figs. 2, 3, and 7) as the web is advanced. From the rolls 4| and 42 the cut off sections h of the web pass to delivery belt 44 driven by rolls 45 journalled in side frames I and 2.
The controllers I9 and 21 and the modulating valve units 2| and 29 may be of any suitable construction of which there are several well known types.
It will be readily understood, without need of illustration, that any suitable motor may be employed for operating the machine, and that suitable gearing is employed in practice to cause the various rolls to rotate at uniform peripheral speed to effect the travel of the web through the machine, in order that the operations of the several units thereof will be effected in the sequence described.
In the operation of the machine the web of paper a is drawn from the supply roll 6 and passes between cylinders 1 and 8 which effect color printing on the said web. The traveling web then passes into oven II for the purpose of applying that to the web a. to rapidly .set the printing ink thereon.
In the operation of the said oven, controller I9 is adjusted, by means of screw 20, to operate when the temperature of dry bulb thermometer l8 varies from the predetermined temperature required to set the printing ink. When the temperature registered by the dry bulb thermometer rises above the predetermined degree, the controller I9 is automatically connected by electric devices with a motor in modulating valve unit 2|. Said motor then operating the modulating valve to diminish the flow of combustible gas to the burner I6, thus reducing the heat and lowering the temperature in the oven. Conversely, when the temperature registered by the dry bulb thermometer falls below the required degree, the controller I9 is automatically connected, by electric devices, with motor in modulating valve unit 2|. The said motor operating the modulating valve to raise the flow of combustible gas to the burner I6, thus increasing the heat and raising the temperature in the oven. The oven II is provided with devices which maintain a predetermined amount of moisture in the air within the said oven. Controller 21 is provided with an adjustment screw 28 with which the controller 21 and the modulating valve unit 29 are regulated to maintain the desired wet bulb temperature within the said oven I I.
The object of introducing moisture into the oven is to maintain a relative humidity of the air within the oven to substantially equal the relative humidity of the airto which the paper was previously subjected. In other words; moisture is added to the heated air within the oven to prevent shrinking of the paper while the printed ink thereon is being set by heat treatment.
The moisture controlling devices operate in the following described manner: When the temperature registered by the wet bulb 26 rises above the predetermined degree, the controller unit 21 is automatically connected by electric devices, with a motor in modulating valve unit 29. The said motor operating the modulating valve to increase the flow of steam or moisture to steam jets 34, thus lowering the wet bulb temperature of the air in oven On the other hand, when the wet bulb temperature registered by the said wet bulb thermometer 26 falls below the predetermined degree, the controller unit automatically connects, by electric devices, with a motor in modulating valve unit 29. Said motor operating the modulating valve to diminish the flow of steam to the steam jets 34, thus permitting the wet bulb temperature to be increased. From the setting oven the printed web of paper a is advanced to pass between rolls 35 and 36 which serve to crease paper articles.
aieaeee rolls M and 42 which cut the folded web into sections to complete the production of the printed The completed articles then pass to delivery belt 46 from which the containers are picked up for use.
Though the invention includes the combined instrumentalities above mentioned, we wish it to be understood that we consider the means not only combinatively novel,.but insofar as we are aware, certain of the devices going to make up such means are new in less combinations than the Whole, as will more clearly appear hereinafter.
While we have shown a preferred method and machine for accomplishing the desired results, it is evident to those skilled in the art that changes may he made to suit the requirements of the article to be produced without departing from the spirit of our invention.
Having now described our invention, what we claim is:
1. The method oi malring'printed paper prod- I note, consisting of printing a web'of paper, ad-
