9 Claims. (Cl. 282-22) This invention relates to manifolding assemblies and similar laminated articles and materials, and more particularly to severance means whereby contiguous units of such assemblies may be readily separated from each other or from a stub wherein portions of each component are relatively permanently secured together.

The general object of the invention is to provide novel and improved severance means for such sheets or assemblies, and methods of preparaing such assemblies with the novel severance means incorporated therein.

Although not strictly limited thereto, the principles of the present invention are peculiarly applicable to the provision of manifolding assemblies consisting of laminations of paper sheets of ordinary weight, or of copytissue consistency, together with at least one lamination of relatively heavy card stock, say of the weight and character of a tabulating card such as Widely used in automatic tabulating and sorting machines.

Many and varied have been the prior provisions for severing manifolding assemblies, and some have been quite adequate and eflicient for assemblies consisting of record, carbon, and copy sheets of ordinary weights of paper, and other have been specially designed for severing card stock alone; but none of these means have proved useful in providing efficient severance for combined card and paper stock. If the severance line pattern ismade sufliciently weak for card stock, it is tooweak for ordinary paper, and the paper components will be apt to be prematurely severed during ordinary handling. On the other hand, if the severance pattern is strong enough for the paper components, it is too adherent for the card element, and either too much resistance to severance is offered or the card is torn or ruptured outside of the severance line and the assembly unit is spoiled.

Another objection to the use of many prior arrangements is the impracticality of the cutting blade configuration for the severance patterns, which in many cases contain abrupt angles, curvatures, and other intricate departures from a straight rectilinear line of severance. Precision cutting of the major transverse severance line requires an unusually heavy, strongly constructed cutting blade, of the sort which is only practical to make if the blade edge is a comparatively straight or at least a gently curved one.

Another feature of novelty in the present conception is the preservation in such a card-and-paper manifold set of accurately cut edges of the card portion after severance, which edges are to be perfectly straight and perfectly smooth, and with all of the inevitable tufts at tie points offset inwardly of the card portion from the general line of severance. This is especially desirable when the card elements of the assemblies are to be run through tabulating machines.

Other objects and features of novelty will be apparent from the following specification when read in connection with the accompanying drawings in which certain embodiments of the invention are illustrated by Way of example.

In the drawings:

Figure 1 is a plan view of a card-and-paper manifolding assembly embodying the principles of the invention;

Figure 2 is a longitudinal sectional view of the assembly taken on line 22 of Figure 1;

Figures 3, 4 and 5 are perspective views respectively of the record card, the transfer sheet, and a paper copy sheet of an assembly unit;

Figure 6 is a diagrammatic perspective view of asimplified schematic representation suggestive of one way in which the novel assembly might be formed;

Figure 6A is a detail view in perspective of i a cutter roll rotated a half turn from its position in Figure 6; and

Figures 7, 8, 9 and 10 are fragmentary plan views of card elements of the novel assemblies illustrating other forms of combined severance patterns which come within the purview of the invention.

One form of manifolding assembly unit produced in accordance with the present inventive concept is indicated generally in Figures 1 and 2 of the drawings by the numeral 10. The assembly in this illustrative embodiment consists of the uppermost card portion 12, the intervening transfer sheet 13 which may be of ordinary single-use carbon paper, and the copy sheet 15 which if desired may be ruled and printed at 16' in the same or similar manner as suggested at 16 in respect to the card element 12.

In the illustrated example, the assembly unit, which is ultimately severed from a combined web as a final step in its manufacture, consists of an intelligence conveying major portion 20 containing the data to be transmitted, filed, or preserved, and a stub portion 21 which of course may be discarded, but which serves the function of preserving the assembly intact during the inscribing of the data upon the record sheet and the transfer of such data to the copy sheet 15 by way of the carbon sheet 13. The

stub 21 serves to hold the three

elements

12, 13 and 15 together by means of the spot of adhesive 23 which is applied to either the underside of the top lamination 12 or the upper face of the bottom lamination 15 to coincide with any type of punched opening 24 made in the carbon layer 13. This adhesive effectively locks the three elements together transversely of the stub 21, and as a practical matter it might better be applied to the underside of the card layer 12 than to the more flimsy web of copy sheet material of which the element 15 is a portion.

The principal portion 20 and the stub portion 21 of an assembly unit are seperated by means of the novel severance means designated generally by the reference numeral 25, but differing in respect to the card portion 12 and the

paper portions

13 and 15 as will be clearly described.

Now bearing in mind the differing strength of the severance means needed for the card portion of the assembly and for the paper portions thereof, and referring particularly to Figures 3, 4 and 5 of the drawings, it will be seen that the severance structure for the card portion 12, as depicted in Figure 3, includes an interrupted rectilinear severance cut b. The several cuts comprising the general severance line b are separated by the rather Wide gap indicated at e. Straddling the adjacent ends of the sections of the severance line b and embracing the ties e are the pairs of arcuate cuts a, each of the cuts a being, for example, of the circular extent of approximately of arc or somewhat less, and the total arcuate extent of the pair comprising approximately orslightly less. The arcuate cuts a are separated by the ties c which ties are located very definitely at points oifset to the right of the rectilinear cut I) or within the confines of the record card element 12 as defined by the severance line b and the remote edge 26 of the element.

The arcuate cuts a and the rectilinear cuts b intersect at the points d, but of course with no tie means at that point to provide any protruding tufts. In other words, the line of complete severance provided by the means 25 in respect to the card element 12 follows along the fragments of the rectilinear cut b to the intersection point d, and thence around the arcuate cuts a to the tie points and these tie points 0 are the only ties for the card'element 12. which renders it quite easy to sever and provides a sharp accurate marginal line along the cut b, between the major portion 20 and the stub 21.

Because the ties c are small and disposed at points relatively displaced from the straight line cuts b, the protruding tufts which result from the severance of the'ties 0 cannot form projections in the final severed edge at 25. Furthermore, the width and relative strength of the ties e insure that the card portion 12 is not broken across these ties but at the much shorter and weaker ties 0.

Now it will be understood that the combined severance means including the arcuate cuts a and the rectilinear cuts b, are applied only to the uppermost or card portion 12 of the assembly 10. and only the discontinuous cuts b are applied to the paper portions which include the carbon transfer sheet 13 and the copy sheet 15. By reference to Figures 4 and 5 of the drawings it will be seen that the only ties to be ruptured in separating the paper portions from its stub portion are the relativelv long ties 2. These ties are quite long and therefore of sufiicient strength to prevent accidental severance of the paper record sheet.

Thus, it will be seen that in effecting the detachment of the record portion 20 of the assembly from the stub portion 21, a ouick hard snapping action will burst the assembly generally along the severance means 25. but with the protrusions between the intersection points at and tie c (in other words, between the inoperative tie e on the card portion and the effective tie c) adhering to the stub portion 21, and any inevitable tuft at the tie point 0 will be enclosed within the arcuate gap in that edge of the card and will not furnish an obstruction or projection at any point along the line b which forms the edge of the card.

With the same tearing motion. the carbon sheet 13 and the copy sheet 15 will be severed generally along the line b through the burstin of the ties e, and since the preservation of an accurate sharp edge along these paper sheets is of no consequence, any tufts protruding after the breaking of the ties 2 will not matter.

In Figure 6 of the drawings certain generically disclosed mechanism is suggested for effecting the process by which the novel manifolding assemblies may be made. The actual mechanical means by which the process may be eifected is of no moment so far as this aspect of the invention is concerned and in fact it is obvious that the process in its broadest sense could be effected by manual means. With these comments in mind, the generic arrangement of Figure 6 will be described. From suitable supply sources. or from a printing press whereby the indicia 16 and 16' may be applied respectively to the card web 30 and the copy sheet web 32, these webs are led into the assembling and cutting areas shown in Figure 6. A web 31 of transfer material is led toward the idler roller 35 to be interposed between the card web 30 and the copy sheet web 32, and by any suitable or appropriate means the transfer web 31 may be provided with the perforations 24 and the underside of the card web may be spotted with adhesive as suggested at 37, these spots coming into registry with the openings 24 and serving effectively to provide the adhesive ties 23 as shown in Figure 2 of the drawings. The pair of rollers 40 and 41 represent a punch roller and an anvil roller for effecting the arcuate cuts a in the card web 30, suitable cleft or notched cutters or punches 42 being carried by the roller 40 for this purpose. Obviously the diameters of the rollers 40 and 41 are selected in accordance with the spacing of the series of severance cuts applied to the web 30.

From the idler roller 45 onward the three

webs

30, 31, and 32 are in superposed position and are fed through the device by means of the pair of pull rollers 46, 47. In advance of the pull rolls 46 and 47 is disposed the pair of severance cutting rollers 50 and 51, the roller 50 carrying the two blades 54 and and the roller 51 acting as an anvil for the blades.

By suitable registry means, the blade 54 which is constituted by interrupted sections 54a between which are the gaps or notches 54b, is arranged to make the transverse cut intersecting the arc a at the points d as already described in connection with the description of the article to be formed. .At substantially the same time the blade 55 effects the terminal cut for separating the assembly unit 10 from the combined web and thus forming the terminal margin 26 of the following unit. Take-away rolls deliver the pack 10.

-It will thus be seen how, by means of the suggested mechanism of Figure 6 or by any other suitable arrangement, the cuts a and b may be separately and consecutively applied whereby both cuts are combined in the card web 30 to form the full and complete severance pattern indicated at 25, whereas the cut b only is applied to the

paper webs

31 and 32.

In Figure 7 of the drawings the assembly unit designated 10A bears the severance patterns shown at 25A which includes the usual interrupted rectilinear cut b with its ties e, but instead of the arcuate cuts a right angle cuts a are used, the transverse portions of these angular cuts in each pair being spaced apart to form the ties c.

In Figure 8 of the drawings the severance pattern 25B is applied to the assembly unit 1013 utilizing the transverse cut b with its ties e but providing the cardboard ties by means of curved angular cuts a In the embodiment illustrated in Figure 9 of the drawings the assembly 10C utilizes a severance pattern 25C which consists of the usual rectilinear cuts b and the divergent angular intersecting cuts a In Figure 10 of the drawings a further variation in severance pattern is applied to the assembly 10D at 25D where the rectilinear cuts b are intersected by the ogeeshaped curved card lamination cuts 11 which terminate adjacent each other to provide the ties c. All of these variations may have their own individual merits for particular purposes, but the general principle still prevails that sharp angles or sudden departures from rectilinear cutting tends to weaken the structure of the cutting blades and the cutting patterns with the gentler curvatures are to be preferred for most purposes.

In summary, it will be understood that the present invention provides a severance structure for card-and-paper manifolding assemblies which assures a perfectly smooth severed edge and which also provides sufiiciently weakened severance means to assure satisfactory parting of relatively strong heavy materials such as card stocks, and at the same time a sufiiciently strong severance means to prevent inadvertent and accidental severance of the paper stock portions of the assembly. The present inventive concept also provides a two-stage fabricating method for making these novel manifolding assemblies with the sequentially applied severance cuts which go to form the variable sevarance features for accommodating both the card portions and the paper portions of the assemblies.

It is also understood that various changes and alterations may be made in the embodiments illustrated and described herein without departing from the scope of the invention as defined by the following claims.
