6Claims.

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 strip interposed between each two adjacent worksheet strips.

Heretofore, it has been suggested that the carbon sheet strip be held captive in the pile against lateral shifting movements and that the 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 adja cent 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 togethensurface-to-surface in registration by means which, while it does not engage the carbon strip, does, however, hold the carbon strip captivein the pile against excessive lateral movement.

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 the pile of strips is severed into form-lengths, which operation may be faeilitated by transverse perforations in the worksheet strips located between form-lengths, as has been done heretofore.

This application is a division of my copending application Serial No. 438,063, filed March 22, 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, with these apertures in the form of marginal cut-outs or notches completely displaced from a transverse tear-oil line. Such cut-outs provide zones of face-to-face direct contact between adjacent worksheet strips, so that these strips may be secured together by suitable securing means located in-saidzones of direct contact.

In the accompanying drawing: I

Figure l is a. perspective view of a manifolding strip made in accordance with the present invention.

Fig. 2 shows a length of said pile, laid out fiat.

The manifolding pile shown in the exemplifying 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 which are divided by lines of perforations II. Interposed between each two adjacent worksheet strips III is a carbon strip Hi. If desired, the 'piie--""" may be folded zig-zag fashion to form a block or pack as shown and the folds may preferably occur on the lines of perforations l2. After a set of forms H has been written upon, it is usually severed from the rest of the pile along the lines of perforations i2, whereupon the forms ll may be separated from each other and from 10 the intervening carbon sheets l3a formed by tearing, to be distributed as desired, or the booklet of forms II and carbon sheets [3a may be left intact to receive subsequent writing or notations. The device of the present invention is particularly advantageous when the latter method is employed, for by itthe carbon sheets 13a are held captive between the worksheets or forms It so that writing on the uppermost form of the booklet 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 secure all of the strips, including the carbon strip or strips, together by staples passing through all of the strips. It was also proposed to hold the carbon strips against shifting relative to the work-' sheet 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 applied while collating the worksheet strips and carbon strips, but it hasthe 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 together by a 7 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 so shaping the lateral margin or margins of the carbon strip at spaced points along the length thereof to provide notches ll defining zones l5 of face-to-face direct contact of the adjacent worksheets with each other, and by locating 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 iii are shown as of the same width as the worksheet strips l0, and with the lateral edges of all the strips in registration, and the notches l4 spaced along both margins of a carbon strip l3.

The securing device for attaching the worksheet strips together in these zones ii are shown as spots liof adhesive, applied to adjacent faces of adjacent worksheet strips It.

When the notches l4 and the securing means I 8 are placed at both lateral margins 01' the pile as shown, the carbon strip I3 is held against substantial lateral shifting movement, and yet, in a booklet comprising a set of forms II and interleaved carbon sheets I341. is severed from the pile,

the carbon sheets lia are held in the 'booklet against casual removal by the tongue-like portions ll of a carbon sheet which'extend between the notches I4 and the adjacent end I8 01 the carbon sheet.

If it is of prime importance that the worksheet strips be held together and unimportant that carbon strips be held captive in the pile against all lateral movements, as might sometimes be the case, the zones l5 may be provided at only one side edge of the pile, leaving the other side of the pile open for easy removal of the carbon sheets l3a from between the worksheets of the booklet resulting from the tearing of! of a set of forms.

Preferably, the zones l5 and the adhesive spots l6 are so dimensioned that when the worksheet strips are affixed together, the carbon strip I3 is not, engaged bythe adhesive and is entirely unaflixed to the worksheet strips so as to be easily separated from the worksheet strips when the written booklet of forms II and carbon sheets l3a have been severed from the pile, and, after that, it is desired to separate the diflerent sheets of the booklet.

The cut-outs II which provide the zones l5 oi direct contact of the adjacent worksheet strips sure causing the underlying worksheets to be marred or soiled by carbon from the carbon strips.

The use of spots of adhesive material is usually preferred for the usual manifolding work such as in ordinary typewriters, since the gum or adhesive may be of a kind having the characteristics of easily being pulled oif the paper or of splitting readily. When adhesive is used, typographical errors may be easily erased on the carbon copies by separating the sheets by merely pulling them apart while they are on the typewriter-platen,

I and then folding back the upper worksheet and carbon strips while the erasure is being made on the lower worksheet strip.

The zones I5 for the securing means may be placed wherever directed in the forms, for instance, as shown, at the tops of the forms.

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