If the sec- 55 ondary folding follows an arrangement in ac-,
cordance with, for example, the primary folding, the secondary folding, when completed, will also present exposed margins for each section of the secondary folding. Therefore, as thus completed, the sections incident to the primary folding will each havean exposed margin which, for the sake of clearness, will be referred to as an index margin, and then each section of the secondary folding which, of course, includes all the sections of the primary fold within the plane of the secondary fold section, will have an exposed or index margin which is particularly or peculiarly adapted to that secondary fold section.
Figures 4 to 8 may serve as a general example of the folding. If the main sheet (Fig. 4) is folded into the primary folds in the longitudinal direction according to the method of folding, for example, shown in Figure 1 to thus provide the primary folds c, c, 0', etc., into the longitudinal sections R, S, T, V, (Fig. 5) and the sheets so folded receive a further or secondary folding at right angles to the primary folds, for example, on the folding lines b, b, b", with each of such secondary folds at relatively different distances apart, one end of the sheet so folded will present relatively exposed free edges exactly similar to those resulting from the primary folds.
If desired and as preferred, each primary fol-d section, except the main underlying section, may
vbe cut through on every second secondary folding (line at b Fig. 4) which will, of course, divide the folds or sections of the primary folding from each other along the lines of each alternate line of secondary folding, so that the sheet as a whole is made up ofconnected primary fold sections which are each subjected to a single secondary fold so that, when that particular secondary fold is opened out, (Fig. 7) the sections included in that particular secondary folding are presented flat in primary fold relation and preferably with their margins offset, so that any priopened out for inspection (Fig. 8).
mary fold of this secondary fold section may be Of course, the primary folds and also the secondary folds may be constructed in any number in accordance with the size of the original sheet and with the desired size of the completed article after folding, the primary purpose of course being to permit the sections of any one secondary fold to be opened out to provide independent access to the sections of the indexed primary fold included therein.
As the sheet is folded longitudinally in secondary folding, that is the lines of secondary folds extend at right angles to the length of the sheet as resulting from the prjmary folds, it is apparent, that any two or more secondary folds may be opened out to provide access to additional lengths of primary folds. Furthermore, in this type of folding, convenient access to any primary fold .section on either face thereof is provided for,
thus permitting the sheet to be printed on both surfaces with any selected material readily available without the necessity of opening up the entire sheet.
The combined fold of this character provides a multiple character of index. As the exposed margin of each of the primary folds may be indexed or marked according to the character of showing on that fold and the exposed section resulting from each secondary fold may be appropriately indexed as to the character of showing on the respective primary fold sections included within that secondary fold, any particular portion of the showing printed on the sheet as a whole is not only conveniently accessible but is also conveniently marked or indexed to be readily and definitely selected with certainty and without loss of time.
The individual sheets may be printed in different colors or be themselves of different color, or may be made of any material, even different materials, or be made up of sheets having colored bands which are parallel to or cross one another.
Any of the sheets, parts of the same, or the cover may be used to bear additional plans or text such as advertisements, illustrations, etc. Cross reference over the parts of a map that has been separated by part cuts will be facilitated by the indexes.
What is claimed is:
l. A sheet of material having imprinted thereon a diagrammatic representation such as a map, which is folded into a number of sections along substantially parallel lines at a progressively increasing distance from each other, the edges on one side of the folds registering with each other and folded again into a number of sections along substantially parallel lines but transverse to the first set of parallel lines, whereby sections with successively exposed edges parallel to each set of fold lines are formed.
2. The device as claimed in claim 1 in which a fold line is out along a portion of its length whereby the sheet may be readily opened to dis play only a small section thereof.
