Abstract

PURPOSE: To enhance the strength of the back of even a book having the number of sheets to be bound is small by entirely connecting the binding parts of the sheets along its longitudinal direction in the case of saddle stitching. CONSTITUTION: A first line group is provided along the center line of one half sheet 5 of a striplike sheet 3, the sheet 3 is folded by a former, the center lines 7, 9 of both the half sheets 5, 6 are connected by the first line group, the folded sheets 5, 6 are cut in a predetermined length, then a second line group is provided along the lines 7, 9, both the folded sheets 5, 6 are horizontally folded and the superposed lines 7, 9 are connected by the second line group. The horizontally folded sheets 5, 6 are folded by a chopper at the lines 7, 9, and three peripheral sides except the sides of the sheets 5, 6 at the lines 7, 9 side are cut.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spine-bonded booklet made of strip-shaped paper that has been subjected to processing such as printing.

[0002]

2. Description of the Related Art Conventionally, in the case of small booklets such as pamphlets sent together with credit usage details or sent as direct mail, the type of saddle stitching by stapling is often used. There is. However, in the case of a small booklet that can be put in this envelope, etc., the number of sheets of paper (signatures) to be bound together is small, so the strength of the spine becomes poor even when stapled by staples, and the booklet easily bends. There is a problem.

In view of the above circumstances, the present invention has an object to bond the binding portions of the sheets together in the longitudinal direction during saddle stitching, and is a booklet with a small number of binding sheets. However, the purpose is to increase the strength of the spine.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems, and from the center line portion along the longitudinal direction of the strip-shaped paper to the center line portion of one of the half paper sheets on both sides. A first line glue is provided, the band-shaped papers are folded in the former, the center line parts of both half-papers are joined by the first line glue, and the folded half-papers are cut into a predetermined length, and then the center-line parts of the half-papers are cut. A second line glue is provided along the two halves, and the folded and folded half sheets are laterally folded together, and the overlapping center line portions are joined by the second line glue, and the horizontally folded half sheet is the center line portion of the half sheet. (EN) Provided is a simple back glue binding booklet, which is characterized in that it is chopper-folded and is cut at three peripheral portions excluding the side portion on the center line portion side of a half-paper, thereby solving the above problems.

[0005]

In the present invention, the center line portions for folding and binding the half-paper are joined together through the line glue (the glue applied linearly), and the joining of the line glues improves the strength of the spine of the booklet. It will improve.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described based on the embodiments shown in FIGS. In the figure, reference numeral 1 denotes a spine-stitched booklet having a surface of 24 pages including a front cover surface and a back cover surface, and the booklet 1 is a booklet 1 in which a folded central portion of 6 sheets of paper 2 is glue-stitched. is there. As shown in FIG. 2, this booklet 1 is obtained from a band-shaped paper 3 on which printing is performed in advance to form each page of the booklet on both front and back sides.
Printing on the band-shaped paper 3 is assigned according to folding. Note that the strip-shaped paper 3 shown in FIG. 2 exemplifies a unit length for producing one booklet, and this unit is continuous before being supplied to the folding process. It is in the state of being.

In the belt-shaped paper 3 supplied after the printing and drying steps are completed, first, from the center line portion 4 along the longitudinal direction of the belt-shaped paper 3 (paper feeding direction), the half papers 5 and 6 on both sides, A first line glue is provided along the center line portion 7 of the one half paper 5. In the drawing, the first line glue is applied from the back surface side of the half paper 5. Further, reference numeral 8 indicates a core provided with the first line glue. Then, the band-shaped paper 3 is subjected to the former folding from the center line portion 4, and the half papers 5 and 6 are folded so that the first line glue provided on the center line portion 7 of the half paper 5 contacts the center line portion 9 of the half paper 6, and the half paper is folded. The center line parts 7 and 9 of 5 and 6 are joined. The core of the former fold is indicated by reference numeral 10. After that, the half sheets 5, 6 (that is, the band-shaped sheets) are cut into a predetermined length in the overlapped state, and a second line glue is provided on the center line portion 9 of the half sheet 6. The core of the second line glue is indicated by reference numeral 11.
Half-paper 5 with the second line glue folded
May be provided along the center line portion of the half sheet (that is, the positions where the first line glue and the second line glue are overlapped in the state where the half sheets are overlapped). It is expressed in a state that follows.

After the second line glue is provided, the folded half sheets 5 and 6 are laterally folded twice so as to be wound in the longitudinal direction so that the second line glue is inward. The center line portions 7 and 9 of the opposite half sheets 5 and 6 are joined by the second line glue by lateral folding. The horizontal core of the horizontal fold is indicated by reference numeral 12. After this horizontal folding, chopper folding is performed at the center line portions 7 and 9 of the half-papers 5 and 6, and the center joined by the first line glue and the second line glue in the signature after the chopper folding Line 7,
The three peripheral portions except the side portion on the 9 side are cut (three-sided cutting) to obtain a booklet 1 with back glue binding. Reference numeral 13 indicates a core for performing chopper folding. In the drawing notation, the chopper folding core is shown at two places, but as described above, the chopper folding operation is performed only once. By doing so, the spine portion of the booklet 1 is formed by the center line portions 7 and 9 joined by the first line glue and the second line glue, and the spine has high strength.

The present invention is not limited to the above-mentioned embodiment, and as shown in FIG.
It may be a booklet having a page, or may be a booklet having a page having 32 pages by laterally folding three times as shown in FIG.

[0010]

As described above, according to the simple spine binding booklet of the present invention, from the center line portion along the longitudinal direction of the strip-shaped paper, the first half paper is placed along the center line portion of one of the half paper sheets. A line glue is provided, the band-shaped paper is formerly folded, the center line parts of both half-papers are joined by the first line glue, and the folded half-papers are cut into a predetermined length, and then along the center-line part of the half-papers. A second line glue is provided, and the folded half lengths of both half sheets are laterally folded together, and the overlapping center line portions are joined by the second line glue, and the half folded sheet is choppered at the center line portion of the half sheets. It is characterized in that it is formed by folding and cutting three peripheral portions excluding the side portions on the side of the center line of the half-paper. In this way, since the back portion of the booklet is glue-stitched over the length direction of the spine, the strength of the spine is significantly improved, and even a booklet with a small number of pages has a spine that is hard to break and durable. In other words, it has excellent practicality.
