ron rrrnwnr'rnns Application filed September 4;, 1e39 Serial No. FY9589.

This invention relates to novel multipleply fan-folded work-webs usable in typew writing machines, such as illustrated, for example, in the'pat'ent to "Wernery and 5 Smith, No. 1,182,055. The carbon-sheets interleave the webplies, being held by trans- "verge blades inserted from the side "of "the V we 1 i The parbOn-s'heetS areshiited backwardly at intervals, preparatory to typing fresh portions oftheweb-lplies. V

. It is desired to have certain of the Webplies of difi-erent color from others, which" result is impracticable when all the plies are made from a single longitudinally fan-fold r edweb.

To avoid these and other objections, Unit-- ed States patent1', lOO,631,granted tome De member 20, 1921, discloses a multiple-ply i work web which may consist of aplurality of;

separate plies of different 'characteristics,hav 7 ing their side edges padded-together at the side by an elastic adhesive material. The blades extend between the plies, being mount-'- ed. on the side of theweb which is oppos e from the glued edges. The padded side edge of said patent is somewhat thicker than the opposite edge, and the work-web therefore may tend to feed-unevenly through typewriters having round platens. The multiple-ply web of the present invention is made up of a number ofloose plies of the inultiple ply webl Moreover, half of the carbon blades can f be set in from theright, and the other half" The webs may be keptseparatedin this Zigza'g'i ashion while they, are run through an oven; and the/adhesive'is dried, sothat 1 when the web is f nally readyfiorfshipinent,

it will be capable of opening up in. zigzag form, like any ordinary "one-piece fan-fold webd The'web maybe packed, and

cross-folded. V V One of the advantages of the Web is that halt oi thej adhesive is used along one edge opposite edge; "A' webmade-this' way may -i. "oi the compos tejweb, and half along the.

run throiigh tlie typewriter-more successfully than were the adhesive all'alon'g one edge Carr be set in from "the left, which is an advantage because the web can be fully "used by re'gularly' equipped typewriters, which would not be the case where all of'the glued edges areon one side, and where consequently all oithe carbon-blades would have'to be set in from a single-side'oi the web.

Other features and advantageswill here-- inattterappear. l

In the accompanying drawings, I Figural is a diagrammatic elevation to illustrate the "printing of the plies, the application of adhesive to ply edges in a manner to form joints at alternate edges'of theweb, the Idrying'of the plies while they reof different colors or grades of paper. All; main properly spread open, and the .crossthe plies are printed first before being as Ysembled into a composite web.

The printed plies may be spools, or from a printingpress, but they 'f are not immediately packed togethen'but Q. p H

Figure i is a EragmentofQfinished composite web.

rigid-e315 a perspective diagram of a The Websor plies 9,10, 11, 12, 13,1)i which A fivejare illustrated (although the. product may comprise more than five plies) are passed simultaneously through a printing press comprising printing, couples 14, where-: by successive forms are printed, the forms upon each plyregisteringwith those on the other plies. From the? printing press, the

it to the side edges of the plies. A separate roll: 2 1v5 or 16is provided foreach pair of'engaging 5 edgeof the next underlying ply. This padding operation leaves the outer plies 9 and 13 each with oneside edge padded and one side edge free. Thus there is provided by the padding operation an equivalent to a longi- 0 tudinally fan-folded work-web.

The composite web can beopened up at each side for 'conveniently'inserting the-carbon-sheets. Each ply ofthe web may have different characteristics, such as color, qual- -ity or thickness. I A Onemethod of padding or fastening the plies together is illustrated, a suitable ad- ;hesive material beingapplied by rollsv 15, 16

;or adhering side edges. Each roll 15 or "16 may be run in asuitable'aperture'inthe'bottomof a font 17 containing'the adhesive, and

the rolls and fonts may in some'cases be 5 provided with any suitable heating device,

. '(n'ot shown) for keeping the paste orjadhesi'v'e in alpr'oper fluent condition. 'Theadhesive may dry quickly...

If desired, the adhesive may be applied to 3 Jthe,edge;of only one OfthBPllGs at each pair .of edges.

All ,j oi ed edges pass between pressure-roll .couples 18, 19, below the fonts. The adhe- 'sive will stick the two plies together.

The length of. one feed-roll or pressure-roll in each couple is much less than the width of p the plies,-because the roll must extend in between theplies whose opposite sideedgesa're f' V pasted. together. The outer ends of -aefeedplies. t The rolls roll couple may be arranged to not quite reach the pasted edges, so that the adhesive mate-' rial will remainonly on the extreme edges of :the engaging plies andthe rolls will not tend .to spreadthe adhesive across the-faces of the may, however, press the pasted edges-of the pliestogether, and stationary stripping -or cleaning knives may be used for keeping the rolls clean from adhesive ma u d terial.

' Auxiliary feed-roll'couples 20 for each pair of plies maybe provided above? the pasters15. All ofthe'dri'ving rolls 20 may be suitably connected with the couples :14 ofthe i 755 printingpress, to secure proper speed 'of' the composite web'as it feeds to the padding apparatus. I e

When the adhesive 14*, on the side edges of u r thepliesis dried, it forms. an elastic film-like c0 element, which fastens one edge'to'the ad-g --joining edge in a way that theplies may be readily'opened'uph V I ,The-f adhesive is applied in usual liquid form, and itis desirable that each pair of adpairs until the adhesive has dried and to be sticky. v

To accomplish this result, Iprovide guides for the plies. These guides or separators 21 may resemble thinprisms 'or wedges, each separating the adjoining plies. The thin ceased edge of a guide-member between two plies is disposed toward the adherent edges.

hesive,-=the composite web, while still held slightly opened, is passed through a drying .oven22. .iTo conduct the composite web into the oven, and through it and out again, the web maybe-made-totake a tortuous path, if

desired. I

To turn the. moving multiple-ply longitudinally fan folded web,it is desirableftoliave theadherent-plies lie as closely against each other, facewise, as is practicable, without bringing-the pasted'and sticky side edge 7 couples into undesired contact; :For this reason the guide-members are preferably made thinner at the-bends, as illustrated. ZSets ofthe feed-rolls 123', 24, are positioned adjacent 'the'de'livery sides of 4 the curved guides, to pullthe plies past the latter.

' The completedw'eb'is.fedbyrolls25 into a cross-folderv 26.

If desired, th webmay-travel a a. e igre 'line from the adhesive 'appliers through'the drying ovens, insteadof takingthe illustrated tortuous path, and wedge-like separators may stlll beuse'd, although/theyneed notbe curved into"Uform,"asjshown at Figure 3.- @Where the 'broad curved separators "21 are employed,they may be used only at: thebends in the traveling I web. The .se paratorsvmay illustrat to conform to the zigzag section of the comp'ositg w b i To expeditethe drying of the sticky ad-o point alternately in opposite directions, as

'Variations maybe resorted to withinthe scopeof the invention, and portions of the improvements may be used without others. 7
