Patented March 9, i909.

tion of'apparatus for printing and drying wall paper wherein I have ldevised novel means for taking a roll of blank paper and passing the same through the ground machine, wherein the firstcolor is applied, the sheet thereafter passing over suitable feeding and drying devices and then through the printing machine, after which the roll of paper is conducted over additional guiding and drying devices and subjected to further treatment. lhen'in the finished condition,- .it is wound upon the roll ready for shipment, the operating being performed automatically and requiring less labor and attendance than heretofore. i

Airadditional feature of my invention consists in the special arrangement of devices whereby the material is more'eiiiciently dried, and larger quantities of material are acted upon in a given length of space and less help is required to operate the same.

For the purpose of illustrating my invention, l have shownonc form of apparatus which l have found in practice to produce effective and reliable results, although it is to be understood that the various instruinentalities of which my invention consists can be variously arranged and organized and that my invention is not limitedto the precise arrangement and organization of these instrumentalities as herein shown.

Figure 1 represents a vertical sectional and diagrammatical view of the right hand portion of an apparatus for printing, treating and drying wall paper, embodying one form of `my invention. Fig. 1JL represents a similar view of the left hand portion. of the apparatus. Fig. '2 represents-on an enlarged scale, a sectional view ofa-structure similar to that shown in the lowerportion of Fig. 1a. Fig. 3 represents `on an enlarged scale, a section on line w-a, Fig. 1a. Fig. e

represents a side elevation of the power transmission means in the right hand end ot the apparatus. .L F ig. 4.a represents the Aleft hand end of the apparatus and is compleiuentaryy to .F ig. 4.

Similar vnumerals of reference indicate corresponding parts in the figures.

Referring tothe drawings. In describing my invention, I will begin with th: blank and trace the roll of paper from the blank to the nished product during the -successive treatments to which it is subjected.

Referring first to Fig. 1, which as stated represents the right hand portion of my machine, 1 designates a roll of blank paper, which is mounted in any suitable supports or framework as 2. In practice theblank roll or reel 1 is usuallyV about three hundred pieces, each piece being eight yards in length, the roll or reel being placed in position as it comes from the paper mill. The paper 3 from the roll 1 passes over the feed roller et, which it will be understood is driven by any suitable means, the blank sheet 3 being fed between the feed roller Il and the iron holder 5 located directly above it, substantially as seen in the lower portion of Fig. 1. The sheet 3 next passes under the strip 6 of canvas or other material depending freely from its support 7, in order to make festoon 8. The paper from the roll travels at aI rate-of speed in excess of the rate of an endless belt or apron 9, which passes around rollers 10 and 1l, of which the. roller 1() is preferably driven while the roller 1 1'revolves in its bearings. Any slack of the apron is taken up by the roller 12. It will be seen that the paper passing out from beneath the sheet or curtain (l at a rate of speed in excess of the apron 9 tends to curl or turn up into shapes of the character indicatedv in the lower portion of Fig. 1, the curtain or sheet 6 being raised at intervals by the paper to permit vthe curved wave of the lfestoon to pass thereunder, dropping immediately to exert a retarding lor dragging effect upon the sheet in order to form the nextl festoon. This is more fully set out 4in connection with Fig. 5.

The festoons 8 supply paper for the ground machine -13 as indicated at the point 14, this machine being timed to take the paper at the same speed as that of feed roller il. AIn the ground machine the tirs-t color is placed on the paper, the blank 14. leading or emerging from the ground machine as indicated at 15 and the blank4 with thetii'st color thereon, as indicated at 16, now passes over the endless apron 17 which travels over the rollers 18 and 19, the roller 18 being shown in Fig. 1 and its coacting roller 19 being shown in Fig. 1.

The paper 16 after passing over the apron '.Fig. 1a and pass over the apron 31 which travels 'on the rollers32 as seenin Fig. 1? and. the roller 33 seen in Fig. 1, said apron l31 being supported in its travel by the rollers 34 and 35 which are arranged in pairs, as indicated in Fig. 1. to the right of the roller 33, the strip 30 passes over the rollers or

tension devices

36, 37, 38, 39 and 40, as indicated in Fig. 1, passing thence into the printing machine as indicated at 41,- in which latter the printing is eii'ected,it being apparent from the foregoing that the paper has received its first color in the ground machine and has been sutciently dried and thereafter having received the desired impression -from the printing machine 41. It 'will be apparent -that it only remains to properly dry and reel the paper for shipment, which operation l will now be described. The stri of paper after leaving-the printing machine '41 will now be indicated as 42 and passes over the apron 43, which travels over the

rollers

44 and 45, the intermediate portion of the ,1

apron being supported by the pairs of

rollers

46 and 47, as indicated in Fig. 1. After passing to the left of the roller 45, the strip 42 travels over the apron 48, which isy supported on the

rollers

49 and 50, thence passing downwardly as indicated in Fig. 1tl upon the apron 51 which is supported upon the'rollers 52 and 53. passing down and under the roller 53 passes over the feed 'roller 54 upon which is an over the'rollers 59, seen in Fig. 1 and the roller 60 seen in Fig. 1, thefestoons 57 now disappearing into strip form again, as seen at the left of Fig. 1, and to which l have applied reference and passing under a tension device 61 and thence over the rollers 62 and 63 and under the strip 64 of canvas or similar material, whereby the' festoons 65 are formed.

66 designates the. apron.supporting the .t'estoons ,65, said apron passing over the After passing The strip 42 after I rollers 67 -and' 68 and. being kept taut by the roller 69. The festoons 65 after leaving thel apron 66, passas indicated at 74 over the slide 71 and thence on to the reel 72, upon which the paper in itsfinished condition is wound in practice the length of sixteen yards. YIt will be understood that in practice the

rollers

49, 53 and 54 are caused to rotate in unison and serve to cause the proper moveinent of' their respective aprons and the. paper traveling thereover. In practice l employ suitable beltiiig or power transmission devices common to the rollers'49, 53 and 54,'so that the same are caused .to rota-te in unison in the proper direction. lt will also be understood that the

rollers

18, and 23 are actuated .in unison in the proper directions by suitable power transmission devices. It will also be understood that the 'rollers 52 and 62 seen in Fig. 1tL are connected by proper belting or power transmission devices, so as to cause the saine to be driven in unison.

It will be understood that the proper drying of the sheet o1" strip of paper during its l travel over the various aprons is, yeffected by means of the piping 73, which may be used for steam or ho`t air. omitted -to show the source of supply of steam or hot air, as it will be understood that the heating medium may be taken from any suitable source and the various series of heating pipes can be coupled up in any suitable manner, as will be evident to those skilled in this art. The structure by which .l these various relations and movements of the aprons are maintained is set out in Figs. 4

and 4a.

It will be understood that in practice the g reel 72 revolves at a very high speed and that the saine receives its power as indicated in. these Figs. 4 and 4a, various shafts, belting, pulleys and speed devices being indicated therein. Starting witli the main shaft 4.75, the power is transmitted through the main belts 76, 77A and 78 with a constantly increasing speed to the final pulley connected to the reel 72. Thel ground machine and f printing machine are driven by a system of iron roller and thence under a strip 56 of canvas or lother suitable material, wheref by the. festoons 57 are formed, which are supported by the apron 58 which passes belting, the printing machine beingdriven from the main shaft 7 5, by means of belt 79, cone pulleys 80 and S1 and shaft 82.

shown in Fig. 4, by belts S7, 92l and 93. Special provision has to be made for driving the various aprons which support the festooiis of wall paper in the drying rooin and before entering the ground machine and l after leaving the drying rooin, in order that j the tight side or face of said aprons will be I have purposely The ground machine is driven, as clearly l on top thus giving a straight and smooth j surface for supporting said f'estoons. The i apron 53 in the drying room is driven from I the main shaft through belts 84, chain geart again, the above operation being repeated4 elige? ing, and belt 86, as is clearly seen by ret ereiice tothe figures. Apron 27 in the dryrooinis driven by ymeans of beits 87, Sti,

Si), chain gearing 90, belt 91 and shaft 29jsuchlength of wall paper is exposed to the drying atmosphere of the drying room.

Referring to Fig. 2 vdetails of a festoon former are shown, which operates substantially as follows :"-The wall paper after passing over the feed roll 52 passes down the space between the inner surface of the dep iding strip 56 of canvas or 'similar inaterial. and the surface speedof the feedroll 54 is considerably in excess of the surface speed of the apron 58 and consequently the -will paper after coming in contact with said apron is forced upv andfoutwardlyaway from said feed wallpand continues horizontally with the movement -of said apron until said canvas strip passes over the upper'surrace ot the festoon,and falls back into place and a continuing series of festoons" formed. The other festoons are made in like'manner.
