. 3 Claims. 1

iThlS invention; relates generally to the art of ;manifolding and is directed particularly to improvements in the ,preparation of certain types Jot-sheets; for use inthe manufacture of onetime :carbon snap-.a-part forms, sometimes known, as snap-sets.

ln the manufacture of snap-sets or snap-amart" forms aspracticed by the small printer, as

edistinguished from the large manufacturer who has the large and expensive mechanical equip- :ment togturnout such sets in-batches. of 25,000 am more, two methods may be employed.

In the ,first method-which the,- so-called small sheetsand the sheets are-easily extracted. ,After :thesets are gathered with the carbon sheetsinterleaved, they are jogged so as to bring allof *thesheets, including the carbonsheets, flush, .or even at the top of thesets. Stacks of these arethen placed under weights ,anda padding .compound is brushed on and the assembled sheets ,-.are thencut downinto sets of desired ,size. This, ,method is unsatisfactory because ,the sets, are .easilybrokenapart for the reasonthatthe pad- .ding compounds, does not penetrate deep enough .a to givethe innerrgummed feature that users of .the sets prefer.

.The second method which the small ,printer -mey .and preferably does, employ is the, inner- ,gumming method. I-Iere, ,after the printing and ;perforating is accomplishedtheuse of a marginal ,lgluer ,and three operators is required, one to mfeedthesheetswand two, to assemble. ,..method the ,carbon sheets are cute full inch In this .shorter. than the printed sheets and. the printed sheets are provided atthe tops with a line about half-way between the top edge and the snap In assembling, the assembler places the bottom.

sheet of a set in a gathering rack and upon this places asheet of carbon paper with the top edge I at the carbon marker line, which position of the .carbon sheet places the bottom edge of the sheet about five-eighths of an inch from the bottom.

edge of the underlying form sheet. The top =sheet.is then, provided ,upon its undersideswith .a .stripof glue which is. of sufficient width.. to adhere, to thebottom sheet and toe portion of the back of the carbon sheetorpaper. This procedure ,isrepeated until the, set is complete. However, thisoperationuis very slow and requires ,,con siderable shill to.be accomplishedwith ,any speed.

In the light of the foregoingit is anobject of the present invention to, provide a novel gummed carbon orscopy. sheet so .that the sets. made up ofthe carbonor cop-y sheetsand other sheets, maybe gathered by the usual bindery,method andcaused to adhere together bythe application ofsteam or by. applying moisture in some other manner as by the use, of a brush, sponge, sprayer or the like whereby there will beeliminated, many of the problems now confronting the small manufacturer of articles of this character.

Anotherobject of the invention is to provide a, carbon or copy sheet, for the purpose described, manufactured with a marginal strip provided with perforations and with an application of adhesive overlying or filling such perforations whereby upon the assembling ,ofthe copy sheet with othersheets, the application of moistureto the edge of the assembled group of sheets along said strip will cause the adhesive to bond f the strip portion of the copying sheet with the aid-- jacent sheets between which the copying sheet lies.

A further object of the invention is to provide acarbon or copyin g sheet with a marginal strip of adhesive applied at the time of the application of the copying material to the sheet, and with aperturesinsaid marginal strip through which the applied adhesive may flow, the apertures being arranged in staggered relation whereby upon the trimming of the carbon sheets preparatory to assembly the adhesive filled apertures of the carbon or copying sheets will be cut through leaving portions of the adhesive exposed at the edge of the sheet so that when moisture is applied to the assembled sheets it will soften the adhesive and cause the latter to flow in between the opposed and contacting surfaces of the several sheets making up the set.

The invention will be best understood from a consideration of thefollowing detailed description taken in connectionwith the accompanying drawings forming a part of the specification, with the understanding, however, that the'invention is not confined to a strict conformity ,Wlth the showing of the drawings but maybe changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a view illustrating diagrammatically the initial formation of a carbon sheet as a ribbon having carbon-free strips extending lengthwise thereof.

Figure 2 is a view in plan of a single formed carbon sheet as cut from the ribbon and prior to perforating the gummed edge area.

Figure 3 is a perspective view of a portion of a pad showing a carbon sheet in place.

Figure 4 is a view illustrating a portion of the gummed area of a carbon sheet showing the apertures filled with gum.

Figure 5 is a fragmentary view of the perforated gummed area of the sheet showing the apertures free of gum and before trimming the sheet for use.

Figure 6 is a sectional view on an enlarged scale through a portion of the gummed area of a sheet and through an aperture showing the gum filling in the aperture.

in suitable lengths and each is later cut by the printer or other person using the same, to the proper or desired size. These strips of the sheet which are left uncoated with the copying material receive the adhesive or gum when the copying sheets are assembled in the manufacture of the previously referred to one time carbon snap-apart forms. In some instances the sheet may be i formed with a central longitudinal carbon free strip.

In accordance with the present invention it is proposed to provide the sheet material, designated Ill, and which is wound up into a roll I I as the carbon is applied thereto. with the longitudinal carbon free edge strip l2 to which a coating of gum adhesive M is applied either simultaneously with the application of the carbon material or subsequently. Where the sheet or ribbon of paper is provided with the central carbon free strip l3, this too may be supplied with the gum coating either at the time of applying the carbon, or later, as may be found most desirable.

In addition to providing the strips or bands of adhesive material along the edges of the carbon sheet, the sheet where the gum or adhesive is applied, is first provided with rows of apertures I5. The apertures of one row are offset from or in staggered relation with the apertures of the next adjacent row so that while the apertures will not merge, they overlap a line extending longitudinally of the row and consequently when the sheet is cut or trimmed along a line paralleling the adhesive coated strip or band. the trim ming knife will cut through a row of the apertures regardless of where the cut is made between the free edge of the sheet and the adjacent edge of the carbon coating.

When the strip sheet of copy material is cut up into the individual sheets, designated Hi, one edge of such single or individual sheets will have the gummed strip or border portion or selvage.

In manufacturing the snap-sets or forms, the

carbon or copying sheets will be assembled in the proper order with record sheets and the assembler needs then only to apply moisture in a suitable manner to form the completed inner gummed snap-set. When the user trims the gummed part of the carbon sheet, which is done before assembling the set, he cuts through the gum or adhesive filled holes I5 which, as previously stated, are staggered so that any trimming will cut through one row of holes, thereby leaving gum exposed to readily adhere to the sheets above and below and to act as a spreading agent of the moisture which would spread to that portion of the gummed copying sheet that is not perforated. This will create or form a more or less solidly glued top the entire length of the form.

It is contemplated as being within the scope of the present invention to apply the adhesive to one face or to both faces of the carbon or copying sheet and while it is preferred that the holes or openings in the copying sheet be filled with the adhesive material, they may remain unfilled without defeating the object of the invention.

A reason for providing the copying sheets-With one side only gummed is that carbon sets are frequently made with an extra carbon sheet on the top or bottom of the set that they may register over or under certain ledger sheets, pay roll cards or bookkeeping records that are used with several shipping orders or records.

Figure 3 illustrates a carbon snap-set which is generally designated ll. These snap-sets are made, as previously stated, by interleaving and gumming of sheets of one time carbon between sheets of printed paper, the printed paper sheets being designated it. These printed paper sheets are perforated along the line l9 adjacent the top edge of the set so that when the printed page or form has been filled in or typed, a quick snap will separate the printed form from the carbon sheet. The carbon, adhering to that part of the form which has been glued to the top of the carbon sheet, is then discarded so that the user of the form does not have to touch the carbon and is not likely to have his hands soiled.

As previously explained, while other methods have been used heretofore for securing-the carbon sheets and the printed paper sheets together, the only method which has been found satisfactory for the'small printer who does not have large and. expensive rotary equipment, is the hand method of assembling the sheets and applying adhesive to the surfaces of the sheets along one edge of the form so that the completed form is fiat and it can be easily passed through a typewriting machine without having the sheets break apart. This hand assembling method is, however, slow and expensive whereas by providing carbon sheets made or manufactured in'accordance with the present invention, such carbon sheets, and the printed sheets can be assembled easily and quickly and be made to permanently join together by the mere application of moisture along the edge of the form where the gummed edge portions of the carbon sheets lie.
