Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a booklet formed by specially folding one sheet of paper.

[Prior art]

When creating booklets such as various magazines, catalogs, pamphlets, etc., I would like to have special pages that are narrower than the original size or conversely have a wide width folded back. There are cases. In such a case, conventionally, the special page is prepared by printing and folding it separately from the ordinary page, and it is overlapped with the part constituting the ordinary page, and sent to the process of wire binding or gluing. There was nothing else. Adopting such a process naturally goes against the requirement of shortening the time required for printing and binding and keeping the cost low.

[Problems to be solved by the device]

It is an object of the present invention to improve the above-mentioned state of the art to eliminate the process for a special page, and to provide a booklet in which the special page is automatically included from one sheet by its special folding. It is in.

[Means for Solving the Problems]

As shown in the drawings, the booklet of the present invention folds a sheet 1 along two vertical folding lines 3 and 3 (4) so that the three pieces of paper divided by these vertical folding lines overlap each other. It is characterized in that it is folded and folded along the horizontal folding line 6 from the center, further folded along the vertical folding line 7 from the center, and the vicinity of the horizontal folding line 6 is cut off. . This booklet is divided into two modes depending on whether the overlapping of three pieces of paper, which is generated by folding along two vertical folding lines, is wrapped in a tongue shape or a Z shape. In the first mode, that is, one side of one wide paper strip 11 is folded along the vertical folding lines 3 and 4, and the narrow paper strips 12 and 13 produced thereby are wrapped in a tongue-like shape, and along the center horizontal folding line 6. When the folding and the subsequent folding along the central vertical folding line 7 are performed, the results are as shown in FIGS. 1, I, II, III and IV. The second mode, that is, one side of one wide paper strip 11 is folded along the vertical folding lines 3 and 4, and the narrow paper strips 12 and 13 produced thereby are folded in a Z shape to form a horizontal folding line 6 at the center. When the bending along the vertical folding line 7 in the center and the subsequent bending along the vertical folding line 7 are performed, the results are as shown in FIGS. 3, I, II, III and IV.

[Action]

The booklet 10C whose cross section is shown in FIG. 2 is obtained by special folding shown in FIG. 1 and cutting off the vicinity of the horizontal folding line 6. This is a four-story building, two of which have a tongue-shaped fold back. On the other hand, if the folding shown in FIG. 3 is cut out, the booklet 10D shown in FIG. 4 can be obtained. It consists of four sheets, two of which have Z-shaped folds.

[Effect of device]

Since the booklet of the present invention is composed of one sheet of paper, the step of preparing a special page is unnecessary in printing and bookbinding. This is particularly significant when printing a large number of copies, using high-speed printing technology such as gravure rotary printing, and connecting it to a continuous cutting paper folding machine to fold it manually or in another process. Since it can be performed without processing, the time required for the printing method is shortened and the cost is reduced. This booklet can be made into a newspaper type by cutting the lower edge and trimming other edges as necessary, and it can be bound into a pamphlet by wire binding the center and pasting it with glue. Needless to say, you can also stack many booklets together to make a thick book. Therefore, the present invention has wide applicability.
