A plurality;ofszigzagrfolded sections are formedin thescarbon sheet; eachsection comprising abettion 20011315175; of= bottom'zpart l. I B l l l-Tjl T118561 successive parts: andsectiohs :are; substant mwpertidn and-a. top. part! III. Thefirst sec- UB2; etc., andsforms amere-strip,=for at Adjacen-t the front Th folds are staggered, so that successive front folds HFI, F2, etc., come progressively closer to the front edge of the carbon holder, as shown most clearly in Figure 4; thereby exposing a narrow strip of each section to the carbon holder bottom sheet for purposes of attachment. This spacing between pairs of front folds HFI, l IF2. etc., is substantially uniform. It amounts, desirably, to a distance such as one-eighth of an inch. The spacing between these front folds I iF and the back folds L in the carbon sheet-the latter being adjacent the line IMP-is also uniform. Desirably it often amounts to a distance such as five or six or seven inches, subject to considerable variation depending upon the type of the stationery for which the carbon sheet is intended. Due to the staggering of the front folds HF and the uniformity of the intermediate section parts ilB, HT, the back folds HL will usually be staggered in a manner similar to the front folds; however, they are not attached to the carbon holder.

The adhesive pads 42 below the front folds HF I are desirably formed by small strips of paper. fabric or the like. Their lower sides are coated with glue 12G or the like for permanent attachment to the top of the carbon holder bottom 5033. Their upper sides are coated with dry sealing adhesiv WA in order to releasably secure the front folds HF to the front part of the carbon holder bottom sheet HB. Preferably the width of every pad or strip i2 is onl a minor fraction of the width of the carbon holder, in order to minimize the time required for release and unfolding and the resulting effects upon the copying characteristics of the carbon sheet. The length of every pad or strip 12 slightly exceeds the dis tance from adjacent the front to the lowermost front fold HF. More particularly, as shown in Figure l, each pad 12 extends from a location between the first front fold HF! and the back folds HL forward to a location directly below the second before last front fold HFX and behind the very last front fold IIFY; thereby allowing immediat use of the uppermost section HT, HB without a releasing operation,

Each carbon holder ill is secured to the form carrier or attachment of the typewriter or other business machine. This can be done by suitable, well-known support arms, clips or the like, inserted in the space between the back folds l iL of the carbon sheet and the back fold ML of the carbon holder. The attachment bar or equivalent device is inserted in known manner between the top and bottom sheets iiiP, 58B of the carbon holder, behind the back fold ML of the carbon sheets. In order to facilitate such insertion said space between the folds l iL and ESL is preferably made long enough for the usual attachment of bars, by suitably locating the attachment pads [2 adjacent the opposite edge of the carbon holder.

For actual operation, there is usually a plurality of the carbon units supported on the form carrier; said units being disposed above one another, manifolded with one sheet of paper or the like below each carbon unit. (In Figure 2 the sheets of paper have been omitted and the vertical spacing between the carbon units has been exaggerated in the interest of a clearer diagrammatic representation.)

At the start of operation, the top section of each carbon sheet is unfolded from within the holder Ill; the front portions of the stationery to be typed upon and the front top portions of the interleaved carbon sheets are lined up at their front edges; and these front edges are then inserted below the platen of the machine, so that they are curved upward as shown in Figure 2. Such insertion is usually accomplished with the platen in raised position. The operator then lowers th platen to its normal typing position and begins actual type work.

As the platen moves from right to left, the form carrier with the system of carbon units and interleaved stationery portions thereon moves along from right to left. Likewise as the platen is turned to change from one line to another the system of carbon units and. interleaved stationcry portions moves with the platen. Forward movement of this entire system is effected by forward turning of the platen. Backward movement of the system is effected upon backward turning of the platen, by mechanism which is conventionally incorporated in the form carrier. Such mechanism, by means of the attachment clips, holds the carbon holders l0 and thereby the forwardly extending section of the carbon sheet it under a slight backward tension, away from the platen.

As a result of such backward tension, the dryseal joint between the top 12A of each adhesive pad 12 and the uppermost front fold HF secured thereto is subject to some little stress in a direction parallel with the plane of the carbon holder paper. Some such stress prevails continuously; and a particularly strong force is applied whenever the platen is turned. I found that a sufiiciently high resistance to a so directed force or stress, to prevent irregular, misdirected shifting of the carbon holders between the stationery sheets, is provided by any of the well-known permanently tacky compounds for dry sealing on paper and the like. Such a compound may contain a rubber or latex base with suitable admixtures, as is well known from the art of adhesives used in mailing envelopes and the like. In the present application the dry sealing compound on top of the pad 12 engages the underside of the carbon sheet ll (normally not coated with carbon ink but sometimes coated with wax W or the like) and holds the same to the pad and thereby to the carbon holder bottom I613 against the forces referred to.

Release of this holding effect is possible, by operations to be described presently.

When a first invoice or other stationery item has been typed the platen is raised again to allow forward pulling of the entire system of sheets; then the operator holds the system of stationery sheets in position while allowing the system of carbons to slide back under the backward tension applied thereto, by a sufficient distance for work on the next invoice; then the first invoice is torn off; the platen is lowered and turned forward or backward a sufficient distance; and the next invoice is typed in the same manner as the first. When this has been repeated a number of times, the portion of the carbon sheet used in this work is sufhciently worn to be discarded. At such times, when an invoice has been completed, the front part of the carbon as well as the stationery is separated from the remainder, in known manner, instead of sliding the carbon back as mentioned before. Depending on the relative length of the unfolded carbon and the stationery used it may or may not be necessary at this time to unfold an additional length of carbon from its folded condition between the top and bottom flaps of the holder 10. If and when such unfolding is necessary it can be efayesecor fected' themanner: diagrammatically: shown:

If therewere-such adhesion with arspent:portionof therpadand if the adhesion were strong, it would become necessary to. apply increasing effort forthe release of.successive. carbon sections. The arrangement as described'on the other hand'involves uniform releasing operations at each front fold I I F. Each adhesive pad I'Zin effect provides a series of short and narrow sealing areas, transversely of the pad," which are spent by releasing operations, one after the other and which thereafter will not apply any strong adhesive action upon the waxed reverse side portions of the carbon sheet successively contacted therewith.

This non-repeat sealing has additional advantages, at least in some instances where relatively delicate carbon coating must be used on the carbon sheet. In such cases the removal of wax IIW from any extended portions of the reverse side would undesirably affect the copying characteristics of equally extended areas of the carbon ink coating. On the other hand, the existence of two or three short and narrow areas so affected is harmless. The areas, as mentioned above, need not be any wider than about one-eighth of an inch and they can be kept at the top edge or bottom edge of the form to be typed upon where they do not interfere with any actual type work.

Accordingly it will be seen that it is most desirable for present purposes to use a somewhat special construction of the adhesive pad and also a somewhat special construction of the carbon sheet. The adhesive pad, dimensioned and arranged in the manner as described, is best formed by a rather thin strip of paper or the like, with ordinary, usually wet sealing and non-tacky adhesive I2G at the bottom side and the aforementioned tacky and dry sealing adhesive IZA on the top side; the dry sealing being suitably selected for cooperation with the reverse side H W of the carbon sheet. It is also possible to apply such dry sealing compound to the top of the carbon holder bottom IfiB direct, at suitable locations; however better results can often be obtained by the separate, double coated pads or strips which I have described. The reason is that different dry sealing compounds may best be provided for diiferentitypes: of Tcarbonsheet reversersidiasaand irrespective ,ofthe idiiferentndimensi ns; imprints: andlothenfeatures-of. the icarborr holders vsand cane hon-sheets; Moreover,".drysealcompounds usable; in engagementnwith the reverse side of s-az. carbon: sheet will..usually tendrtoaadhere also tortlie paper of' a carbon holder: For:this reasomthey:would; complicate; the; manufactures-and; storagecof 5 care bon h0lders;..

While the carbon holder bottom itself is substantially obscured by overlying carbon sheet sections, and in any lower, manifolded unit also by overlying stationery, the markers I2P on the uppermost carbon paper unit will show very clearly the successive points to be held down for the unfolding of each carbon sheet.

The fact that these markers, and the seal strips themselves are located at the front edge of the unit provides a further advantage in simplifying the carbon release and supply operation. The operator can perform the entire operation from the normal typing position, with greater ease and convenience than if the attachment were efiected along the side or back edge of the unit. Moreover the front attachment described has the further advantage that practically no part of the carbon sheet is wasted; everything but the narrow bottom section IIBI can be used up for actual typo work.

It will be understood by persons skilled in the art that various additions and modifications are possible. For instance the unit may contain a protective paper sheet in addition to the carbon sheet shown and described, in which eventthe carbon sheet may be carbon coated on both sides. The sheet II may also be coated with transfer materials other than carbon ink; and various other modifications can be applied.

I claim:
