MANIFOLDING FILE Original Filed March 22. 1930 INVENTOR Brezzn vA'l-ro Y Patented Jan. 11, 1938 MANIFOLDING PILE Carl W. Brenn, Montclair, N. J., assignor to Antographic Register Company, Hoboken, N. 1., a corporation of New Jersey Original application March 22, 1930, Serial No. 438,063. Divided and this application March 12, 1937, Serial No. 130,439


This invention relates to manifolding means, and more particularly, to a manifolding pile comprising a plurality of superposed continuous worksheet strips and a continuous carbon sheet 6 strip interposed between each two adjacent worksheet strips. v

Heretofore, it has been suggested that the carbon sheet strip be held captive in the pile against lateral shifting movements and that the 10 worksheet strips of the pile be held together in registration by securing means such as staples extending through all of the strips of the pile.

In cases where it is merely desired to hold the carbon strip to the worksheet strip, it was proposed to employ spots of gum between the adjacent faces of the carbon strip and worksheet strip.

An object of this invention is to provide a manifolding pile in which the worksheet strips are held together surface-to-surface in registration by means which, while it does not engage the carbonstrip, does, however, hold the carbon strip captive in the pile against excessive lateral move ment.

It is a further object of this invention to so provide the manifolding pile just described that the carbon is held captive between'the worksheets both before and after tne pile of strips is severed into form-lengths, which operation 30 may be facilitated by transverse perforations in the worksheet strips located between formlengths, as has been done heretofore.

This application is 'a division of my copendng application Serial No. 438,063, filed March 22,

5 1930; and according to the invention of the present application the objects aforesaid are attained by providing a carbon strip which is apertured at intervals along the length of the same, and at points inwardly removed from the lateral edges 40 of the manifolding pile. These apertures provide ,::ones of face-to-face direct contact between adjacent worksheet strips, so that these strips may be secured together by suitable securing means located in said zones of direct contact.

45 Also, according to the present invention, as

the same is preferably carried out, the carbon strip apertures through which the devices for securing together the worksheet strips extend are larger than the securing devices, so as to pro- 50 vide for limited relative adjusting movements between a worksheetstrip and an adjacent carbon strip. v

In the accompanying drawing: 55 a Figure 1 is a perspective view of a manifolding tpii'le made in accordance with the present inven- Fig. 2 shows a length of said pile, laid out flat.

Fig. 3 is an enlarged detail view, being a section taken on the line 3-3 of Fig. 2.

The manifolding pile shown in the exemplify ing embodiment illustrated in the drawing comprises a plurality of continuous worksheet strips ID, of which there may be two or more, having a succession of printed forms or form-lengths ll 10 which are divided by lines of perforations l2. Interposed between each two adjacent worksheet strips I0 is a carbon strip l3. If desired, the pile may be folded zig-zag fashion to form a block or pack as shown and the folds may preferably 15 occur on the lines of perforations I2. After a set of forms H has been written upon, it is usual- 1y severed from the rest of the pile along the lines of perforations I2, whereupon the forms H may be separated from each other and from the intervening carbon sheets I3a formed by tearing, to be distributed as desired, or the beaklet-of forms II and carbon sheets l3a. may be left intact to receive subsequent writing or notations. Thedevice of the present invention is particularly advantageous when the latter method is employed, for by it the carbon sheets I341. are held captive between the worksheets or forms I I so that writing on the uppermost form of the bocklet will be reproduced on the under forms by the carbon or other transfer material.

Heretofore, it was proposed to fasten the strips together so as to hold the carbon strip captive between the worksheet strips by adhesive applied to the edges of the strips of the pile when the pile is compressed. It was also proposed to se cure all of the strips, including the carbon strip or strips, together by staples passing throughall of the strips. It was also proposed to hold the carbon strips against shifting relative to the worksheet strips by spots of gum or other adhesive material located between the adjacent faces of the worksheet strips and the carbon sheet. strips. This latter proposal has the advantage of permitting the securing means to be i applied while collating the worksheet strips and carbon strips, but it has the disadvantage of not holding the worksheet strips in the pile together against lateral shifting movement relative to each other.

According to the present invention, the advantage of being able to apply the securing means during the process of collating the worksheet and carbon sheet strips is retained, but in addition the securing means also serves the function of holding the worksheet strips against lateral shifting movements relatively and yet permits the carbon strip to be entirely free of adhesive material and avoids subjecting the carbon strip to pressure which is applied to cause the worksheet strips to adhere together or to be secured to-.

' the lateral edges of all the strips in registration, and the apertures M are shown as holes in the gether by a staple, thus avoiding the marking of the face of the under worksheet as a result of this pressure.

This is accomplished, according to the present invention, by providing a series of apertures 14 in the carbon strip, these apertures inwardly removed from the lateral edges of the pile to provide zones of face-to-face direct contact of the adjacent worksheets with each other, and by 10- cating the adhesive, staple or other worksheet strip securing means in these zones of direct contact.

In the form of the invention illustrated in the drawing, the carbon strips I3 are shown as of the same'width as the worksheet strips l0, and with strip in and the worksheet next below.

, The securing devices for attaching the worksheet strips together in these zones l5 are shown as spots 16 of adhesive, applied to adjacent faces of adjacent worksheet strips I 0.- Preferably, the zones 15 and the adhesive spots 16 are so dimensioned that when the worksheet strips are 'aflixed together, the carbon strip I3 is not engaged by the adhesive and is entirely unaffixed to the worksheet strips so as to be easily separated from the worksheet strips when the written booklet of forms II and carbon sheets 13a have been severed from the pile, and, after that, it is desired to separate the difierent sheets of the booklet. I

Prior to the sheet separation last referred to, however, each carbon strip I3 is held in 'place in the pile and against removal from adjacent worksheet strips H, but without being directly secured to the latter; both in the pile and in a booklet severed from the pile.

It should be understood that the zones of direct contact of the adjacent worksheet strips with each other are placed at intervals along the pile and preferably at least one in each form so that the worksheets may be held together by the securing means after a set of superposed forms has beensevered from the pile. It should also be understood that by having the securing means located in a portion of the pile uncovered by the carbon strip, pressure may be employed in applying the securing means, for instance, the gum spots 16, without that pressure causing the underlying worksheets to be marred or soiled by carbon from the carbon strips.

The use of spots of adhesive material is usual- I 1y preferred for the usual manifolding work such as in ordinary typewriters, since the gum or ad hesive may be of a kind having the characteristics of easily being pulled off the paper or of splitting readily. When adhesive is used, typographical rrors may be easily eras ed on the carbon copies by separating the sheets by merely pulling them apart while they are on the typewriter platen, and then folding back the upper worksheet and carbon strips while the erasure is being made on the lower worksheet strip.

The zones 15 for the securing means may be placed wherever desired-in the forms, for instance, as shown, at the tops' of the forms, or at the bottoms of the forms, or both at the tops and bottoms of the forms. Even with the securing means at the tops as well as at the bottoms of the forms, such erasures as those just mentioned could be made easily, as the pulling apart of the sheets at the upper ends of a set of forms would break the securement between these sheets.

The result of holding the carbon strip or strips in the pile against substantial lateral movement, while also permitting limited relative adjusting movements between the carbon strips and the worksheet strips, may also be accomplished by the invention, by making the apertures 14 larger than the securing means. As these apertures are shown, they are so dimensioned relative to ,the securing means, here the spots of adhesive l6, that annular portions of the zone l5 surround the securing means. When such or an equivalent arrangement is provided, the worksheet strips wil be secured together, and relative adjusting movements may occur betweenthese strips and the carbon strips l3, and yet the carbon strips will not be free to shift laterally to any substantial or undesirable extent.

Variations and modifications may be mad within the scope, of this invention and portions of the improvements may be used without others.
