Description

[Detailed Description of the Invention] This invention is applicable to books, catalogs, pamphlets, manuals, guidebooks, etc. in which paper is bound by gluing.
It relates to booklets such as application forms, question papers, record books, memo pads, etc., and their manufacturing methods.

Conventionally, in order to manufacture the various types of booklets mentioned above that are bound with glue, multiple sheets of paper each consisting of two front and back pages are stacked together, glue is applied to the inside of the spine or edge of the stacked sheets, and the stacked sheets are glued together. or by folding paper consisting of four pages on the front and back.
It was manufactured by stacking multiple sheets of folded paper, applying glue to the inside of the spine or edge of the folded portion, and gluing the folded sheets together.

However, in the above-mentioned conventional method, the process of adhering the sheets together is complicated, resulting in uneven adhesion between the sheets or missing pages, which is inconvenient for manufacturing and use. Further, when continuously manufacturing booklets in which each page is printed differently, the number of stacked sheets is limited, which is inconvenient.

Therefore, in the present invention, in view of the above-mentioned drawbacks of the conventional booklet and its manufacturing method, even when manufacturing a booklet in which each page is printed differently, uneven adhesion between sheets may occur or missing pages may occur. To provide a booklet that can be manufactured continuously without drying up, has a large number of pages, and is convenient for viewing and listening, and a method for manufacturing the same.

Next, the present invention will be described based on drawings showing one embodiment of the present invention.

FIG. 1 is an explanatory diagram of the manufacturing process of a booklet according to the present invention. In the case of manufacturing a 16-page booklet, four continuous sheets of rolled paper P ₁ , P ₂ , P ₃ ,
P ₄ has a width twice that of the booklet, and has folding parts 11, 12, 13, 14 approximately in the center of the width of each sheet.
(See Figure 2), the first page is printed on the right side of the folding part 11 in the direction of paper travel on the surface of the continuous paper P ₁ , and the 16th page is printed on the left side with the printing unit A ₁ .
The 2nd page is printed on the back side of the page, the 15th page is printed on the back side of the 16th page by printing unit A ₂ , the 3rd page is printed on the right side of the folding part 12 in the direction of paper travel on the front side of continuous paper P ₂ , and the 3rd page is printed on the left side. The 14th page is printed on printing unit B ₁ ,
The 4th page is printed on the back side of the 3rd page, the 13th page is printed on the back side of the _14th page, and 5 pages are printed on the right side of the folding part 13 in the direction of paper travel on the front side of the continuous paper _P3 .
The 12th page is printed on the left side by printing unit C ₁ , the 6th page is printed on the back of the 5th page, the 11th page is printed on the back of the 12th page, and the printing unit C ₂ is printed continuously. Paper traveling direction folding part 1 on the front side of paper P ₄
4 The 7th page is printed on the right side, the 10th page is printed on the left side, and the _8th page is printed on the back side of the 7th page.
The ninth page is printed by printing unit _D2 on the back side of the page.

Next, the continuous sheets P ₁ , P ₂ , P ₃ , and P ₄ are transported so that their respective folding portions 11 , 12 , 13 , and 14 are overlapped.
Folding portions 11, 12 of P ₂ , P ₃ and P ₄ , respectively;
13, 14 have perforation units 22, 23,
Folding perforations 12', 13', 14' by 24
is provided, and then the glue unit 32 forms perforations 1 on the surface of the continuous paper P ₂ in the direction of paper advance.
Adjacent to the right side of 2', glue 32' is applied in a linear form, and the glue unit 33 applies glue 33' in a linear form adjacent to the left side of the perforation 13' for folding in the paper traveling direction on the surface of the continuous paper _P3 . Furthermore, the glue unit 34 applies glue 34' in a linear manner adjacent to the right side of the perforation 14' for folding in the paper traveling direction on the surface of the continuous paper _P4 .

After that, the folded parts 11, 12, 13, and 14 of the continuous papers P ₁ , P ₂ , P ₃ , and P ₄ are aligned, and while each paper is continuously overlapped and transported, appropriate pressure is applied to the glue-applied part. In addition, a booklet 50 can be obtained by gluing each sheet of paper together and then cutting it into print units by the cutting unit 40.

In addition, in the above, as an alternative to the folding perforations, folding weakening lines such as crease lines and embossing lines may be provided in the folding portions, and these weakening lines are used to align and overlap each folding portion. It may also be provided at the same time.

In addition, the glue should be adjacent to the left or right side of the folded part, and its width should preferably be in the form of a line with a width of 0.5 to 2.0 mm. Adhesion conditions such as heat and pressure may be applied.

In addition, in stacking and transporting each continuous form, as in the production of continuous forms used as printing paper for printers, which are output devices for electronic computers, the edges or folded parts of each continuous form are approximately 1. It is advisable to provide punch holes at regular intervals along an area within an inch to check the printing position and paper progress, and use these punch holes to overlap the printing positions and folding parts of each continuous paper and to perform the folding described later. . 6 in Figure 1

Furthermore, the booklet 50 obtained as described above is the third
As shown in the figure, it is used by being folded so that the first page is exposed, but when folding, a weakening line is provided at the folding part, and after each sheet is glued, it is cut into booklets for each unit. The booklet may be folded in a continuous state along the line of weakness immediately before the booklet is opened, or it may be folded by the user of the booklet.

The booklet of this invention obtained as described above is
Each sheet of paper is glued in the center of the paper, which is twice the size of the booklet, so the adhesion is stable and the paper does not fall off during use.Glue is glued alternately on the left and right sides of the folding section, so there is no glue in the folding section. The thickness of the paper is halved, and when opening each page, every other sheet can be completely spread from the folding part as shown in Figure 4, and this prevents the bulging of the paper due to the inside of every other sheet as shown in Figure 5. This problem is solved with every other sheet, and since a weakening line for folding is provided at the folding portion of the desired sheet, it is easy to use the sheet as a double-page spread.

Moreover, in manufacturing the booklet of this invention, 4
Since each page is made into one sheet of paper, the thickness during stacking and bonding transfer is half of that of conventional paper, making it easier to transfer.Also, since the paper is in a flat state until the stacking and bonding stage, the process is not complicated, and each other's Paper can be glued in a stable state, and since the glue applied in a line on the front and back of the paper is applied through the thickness of the paper and the folded part, it does not cause any adverse effects such as wrinkles on the paper. Moreover, since the thickness of the glue does not increase, it is easy to adjust the amount of glue depending on the quality of the paper or the glue, and stable adhesion can be achieved.

In addition, since the sheets are glued together through the folded portions of each other, and a line of weakening for folding is provided at the folded portion of the desired paper, it is possible to easily produce a folded booklet from the folded portion. have
