CONTINUOUS BAND OF FORM SETS Filed July 20, 1959 2 Sheets-Sheet 2 United States Patent() 3,081,110 v CONTINUOUS BAND OF FORM SETS Philipp Drescher, Raffaelweg 14, Stuttgart, Germany Filed July 20, 1959, Ser. No. 828,260 3 Claims. (Cl. 282-115) Sets of forms are known which consist essentially of sheets of forms for Writing thereonwith sheets of carbon paper interleaved therebetween, while all of said sheets are glued together along a heading strip. 7
In a suitable construction of these sets of forms, the sheets of carbon paper are displaced at the foot of the form so that, by grasping the sheets of forms, which have a perforation along the heading strip, they can be separated from :the sheets of carbon paper. Furthermore, itis known to place these sets of forms behind one an other such that they produce together a continuous writ ing strip. I
With these known sets of forms, there is encountered the difiiculty of connecting the individual sets of forms to one another in a closed chain-like manner so that the longitudinal gaps on the printed or unprinted paper strip run exactly in a continuous line. The stamping in of registering openings on the heading of the set which should coincide with the position of the individual sets ensures an accurate position only when all holes of all sheets are produced simultaneously with the printing and the sets are accurately fitted by pinning on to the holes.
As this procedure is very complicated and time-consuming, it has been proposed to effect the perforation'after the -placin'g'togeth'er whereby considerable deviations can arise on all sides.
' Numerous proposals have already been made to place the sets of forms in continuous series arrangement with one another. Thus, for example, it has been proposed to print one of the sheets and in fact, preferably either the last or the first sheet, as a continuous strip, and place the remaining sheets and the carbon papers as individual parts on this continuous strip whereby a chain is formed.
The considerable disadvantage of this heretofore known arrangement consists in "that'the continuous strip must be printed and produced in the longitudinal direction while the individual sets should be'prepared in crosswise direction. Such an arrangement, however, leads to a great danger of deviations in registering the printing of the differently printed sheets.
These known constructions have several serious drawbacks. First, in order to pull out the carbon paper sheets, these must always be seized by the hand on one side whereby the fingers become dirty. Furthermore, when rotating the papers on the platen in the typewriter, the writing sheets and carbon paper sheets are displaced over one another due to the unequal distance of the sheets placed over one another on the axis of rotation of the platen. With this mutual displacement of the individual sheets, the blocking of the sheets of carbon paper at their lower edge leads to a swelling on the lower edge of each individual set of writing so that the writing set cannot pass free of swelling through the machine. Disturbing crush folds occur and, on uniting the individual sets of writing into a continuous strip, an undisturbed passage through is practically impossible. The swelling of the individual pieces of paper is particularly great with the known continuous sets in which the cover sheet and the lowermost writing sheet are extended beyond the foot of the writing set, are lead together in their lengthened part and then glued together and at the same time are glued onto the same part of the following set of writing paper. In this instance, the swelling is caused by the fixed connection of writing and carbon sheets at the foot part of each set of copies.
3,081,110 Patented Mar. 12, 1963 set, can accurately and mechanically be placed over one another.
It is, therefore, an object of this invention to provide a long band or strip of sets of writing material, which will overcome the above mentioned drawbacks.
It 'is another object of this invention to provide a long band or strip of form sets which will not require a special carrier band as auxiliary means for the continuous strip.
It is still another object of this invention to provide a long strip or band of form sets which will permit an absolutely accurate alignment of the sets of forms with the aid of extremely simple and cheap means.
These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing in which:
FIG. 1 is a face view of a part of a continuous set of forms according to the invention.
FIG. 2 is a diagrammatic longitudinal section through the set of forms of FIG. 1.
FIG. 3 is a diagrammatic view of a continuous set put together to a pile.
FIG. 4 is a diagrammatic longitudinal section through a set of forms according to an alternative embodiment.
General Arrangement The continuous sets of forms according to the present invention comprises writingshe'ets connected to one another at the heading side with sheets of carbon paper part of the cover or top slrtee'tof 'the following continuous set.
In further conformity with the invention, the individual writing and carbon paper sheets of each set of forms at the foot end are placed over one another so as to be freely movable, "and are sufficientl-y"spaced fromthe heading part of the adjacent set of forms. In order to be able mechanically to place the Writing and carbon paper sheets together in a very simple manner, according to a further feature of the invention, any form of perforation, so called registering holes, are provided in every head part and the lengthened foot part.
By means of the perforations and holding pins, the individual sets glued together into a continuous band are held together accurately until the glue holds firmly and is accurately dried.
A perforation can be provided on the edge of each heading part in a manner known per se. It is possible to provide the perforation, scoring or the like directly on the folding place between the individual copy sets. One may, however, also provide on the folding place a score and an actual separating perforation above the scoring. In the continuous sets of forms constructed according to the invention, the sheets of carbon paper are fixed in the heading part of each set of forms together with the sheets of writing paper. Furthermore, it is feasible in a manner known per se to make the sheets of carbon paper short at the foot part so that the writing sheets project by a uniform amount beyond the carbon papers.
In the manufacture of the continuous set of forms according to the invention, the stamped sets of forms are in a manner known per se accurately placed in series with one another by a machine, for example by means of pins,
and the projecting foot part of the preferably uppermost sheet to be written on is glued by machine and struck on to the heading part of the following set.
Structural Arrangement The improved continuous set of forms illustrated in the drawing comprises an uppermost sheet 1 on which the layout is printed, and a number of copy sheets, 2, 2, 2", 2". There may be any desired number of these copy sheets. Between the form 1 and the copy sheet 2, and between the adjacent copy sheets, sheets of carbon paper 3, 3', 3", 3" are placed. These sheets of carbon paper 3, 3, 3", 3 are placed at the foot of the form in known manner. All the sheets, likewise in known manner, are glued together at the heading strip. The heading strip carries also the perforations 4 which pass through the writing sheet 1.
The uppermost sheet 1 of each set of forms, which is the writing sheet, is lengthened in known manner beyond the foot of the set and the heading part is provided with registering holes 5, 6. The extended part 1 of the uppermost sheet 1 engages over the heading part of the next succeeding set of forms and by its adherence to the top sheet 1 thereof makes up a continuous band which carries and guides the two sets of forms.
In the same manner, the uppermost sheets 1' and 1" of the following sets of forms are connected to one another so that, finally, a continuous band results which can be as long as desired.
According to the invention, the individual copy sheets 2, 2', 2", 2 and the interleaved carbon paper sheets 3, 3, 3", 3 of each set of forms, lying freely movable over one another at the foot of the set are held at a sufiicient distance from the heading part of the adjacent set of forms so that on passing through the typewriter a free unimpeded deflection of the individual sheets is possible.
It is feasible for the idea of the invention to be effected if, instead of the cover sheet, another sheet is united in the manner according to the invention by a connecting strip. An even more complicated construction of this idea would be if, for example, the longitudinal strip on the foot of the form consisting, in the subject matter of the invention, of one piece with the cover sheet were omitted. The writing sheets of the set of forms, therefore, are made uniformly long and the connection of the sheets produced by sticking on of individual connecting strips with the register openings provided.
In the embodiment illustrated, the perforation is provided at the folding place between two sets. As this place, in consequence of the zig-zag laying, is mechanically highly stressed, it may be preferable to provide the separating perforations above the fold. The actual folding place is then, instead of a perforation, replaced by a known grooving.
If sets for punched card writing are formed, known guide holes are located on the edge sides of the sets.
It is, of course, to be understood that the present invention is, by no reason, limited to the particular construction shown in the drawing but also comprises any modifications within the scope of the appended claims.
What I claim is:
1. In combination: a plurality of like individual sets of forms arranged end to end, each of said sets comprising a plurality of superimposed alternately arranged writing sheets and carbon sheets with one of said writing sheets forming the top sheet of the respective set and with the carbon papers facing down away from said top sheet, the writing sheets and the carbon sheets of each individual set being interconnected at their head ends only, only said top sheet of each of said sets extending beyond the foot ends of the other writing sheets and carbon sheets of the respective same set of forms and being connected to the top portion of the respective next succeeding set of forms while the foot ends of all sheets below said top sheet of each one and the same individual set of forms are movable relative to each other and are slightly spaced from the head portion of the respective next succeeding form set to allow folding of each form set upon the respective next succeeding form set.
2. An arrangement according to claim 1, in which that foot portion of said top sheet of each set of forms which is connected to the respective next succeeding set of forms and the head portion of the letter are provided with aligned holes.
3. An arrangement according to claim 1, in which the foot portion of said top sheet of each set of forms is provided with a groove above the top portion of the respective next succeeding set of forms and in which a line of weakening is provided in said top sheet directly above said groove.
