Abstract

PURPOSE:To align punch holes of the same shape at a fixed dimension from the back by a method wherein a cutting chain line is made in a printing stage prior to folding, and the punch holes are made in a stage for binding sheets with the back aligned prior to the adhesion of a back guard sheet. CONSTITUTION:Firstly, a cutting chain line (x) has been made by a relief printing technique simultaneously with the printing on paper. Next, a plurality of unit sheet groups 1, 1' are made, and the sheets are lapped and bound by a stitching or other method with the back aligned. Punch holes 3 are mechanically made at a fixed dimension T from the back. A back guard sheet 5 applied with an adhesive 4 on the adhesion surface thereof is prepared and bonded to the back. Thereafter, doubled end leaves are lapped on and under the bundle of sheets and bonded to the back guard sheet 5. Then, the bundle of sheets is cut into a predetermined size, a cover is bonded to the outside end leaves, and a book is completed. In this manner, the punch holes can be aligned without marring the appearance of the book.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing notebooks such as dual-purpose notebooks that can also be used as loose-leaf paper sheets.

(Prior Art) In general, the method of manufacturing this notebook is to fold a plurality of unit sheets, which constitute each sheet of a predetermined version, by folding such as winding, aligning the backs of the folded portions on the binding side.
Glue it to the spine mount, stitch it to the required thickness K, and add
Overlap the endpapers and attach the cover.

In this notebook manufacturing method, the present inventor newly proposes the creation of notebooks and other notebooks that also serve as loose-leaf paper sheets. In this case, each sheet of the notebook must be easily cut out along the perforation line, and each sheet must have punch holes for loose leaves.

(Problem to be Solved by the Invention) Therefore, it was considered to form cutout chain lines and corresponding punch holes for loose leaf on the paper surface before folding, but due to the folding accuracy, the error was large, so it was not possible to staple the paper. When this happens, there is a problem that the punched holes become uneven, spoiling the appearance of the book, and lowering the product value. Also,
If the punch holes are punched after the book is finished, the punch holes will be visible on the outside of the cover, spoiling the appearance of the book itself.

(Object of the Invention) The present invention has been made based on the above circumstances, and the cut-and-dash lines are formed in the printing stage before folding, and the punch holes are aligned and stitched together on the back side before gluing the spine mount. By forming the paper in stages, the paper is made to have a shape that matches a certain dimension from the back, and the punched holes are aligned to create a book with an excellent appearance.

(Means for Solving the Problem) For this reason, in the present invention, in order to completely form the cut-off chain line for cutting at a predetermined width from the folding point I on the binding side, the step of simultaneously forming the above-mentioned cut-off chain line at the time of printing before folding. And, after folding, a step of drilling a loose-leaf edge hole inside the above-mentioned cut-and-dash line is added at the stage of binding to the required thickness.

(Embodiment) Hereinafter, one embodiment of the present invention will be specifically described with reference to all the drawings. Figure 1 shows how each paper sheet ASB...H (and A'
, B', . child\
The dotted line 2 is a planned folding line, and as a result of winding and folding, a cut-off chain line ! ”, incisions are formed simultaneously with printing on the paper surface (not shown).

Then, the above-mentioned paper sheet S is
When folded, each sheet of paper A, B...H (and B'...l(/
), the cutout chain line X will be located in a heavy state. This positional error depends entirely on the positional deviation of the folding line, so in anticipation of the folding order, each tA
, tB...tH is tA=t+ΔtA, tB=t+Δt
It can be corrected in advance in the form of B.

In this state, multiple groups of unit sheets L (and one sheet are stacked on top of each other with their binding side backs aligned (see FIG. 3(a)),
This is done using traditional methods such as stitching. Next, punch holes 32!i- are mechanically formed on a bundle of paper sheets of a predetermined thickness (T(t), in line with the above-mentioned back surface, at a distance of a predetermined distance T (see Fig. 3)). . Next, a back wrapping mount 5 (see FIG. 3(C)) having an adhesive 4 bonded to its adhesive surface is prepared, and bonded as usual (see FIG. 3(d)).

After that, the endpapers 6 folded in half are stacked on top and bottom of the bundle of paper sheets and glued to the spine mount 5 (see Fig. 4), and then cut as shown in Fig. 5 to cut the top and bottom edges of the paper sheets. and an opening edge are formed, and the cover 7 for each main body N, N2 is completed by gluing it to the outer side of the facing paper 6 (see FIG. 6).

According to such a manufacturing procedure, the punch holes 3 are not formed on the outside of the cover 6, so the appearance of the book is not impaired. In addition, since the punch holes are formed in a stack of books, the punch holes are not irregular, so the punch holes are in an orderly manner and do not reduce the product value. In particular, even if there is an error in the interval t due to positional deviation of the folding line,
Since the dimension from the punch hole 3 to the facing edge of the sheet is uniform, when used as a loose-leaf book by cutting it along the dotted line, the facing edges of the sheet in the loose-leaf book will be aligned, and it will be normal. It is possible to maintain the same appearance as when using loose-leaf paper sheets.

(Effects of the Invention) As described in detail above, the present invention was designed to construct a new notebook with paper sheets that can be converted to loose-leaf paper by devising a manufacturing procedure for the notebook. , the punch holes are aligned without damaging the appearance, and the product value can be maintained, and even when used as a loose leaf, there is the advantage that the facing sides are aligned.

Claims (1)

[Claims] Multiple groups of unit sheets that make up each sheet of a predetermined version by folding such as rolling and folding are aligned with the back sides of the folded parts on the binding side, adhered to a spine mount, and stapled to the required thickness. In a method of manufacturing a notebook in which endpapers are overlapped and a cover is attached, in order to form a chain-cut line for cutting at a predetermined width from the folded point on the binding side, the chain-cut line is simultaneously formed during printing before folding. and a step of punching loose-leaf holes inside the cut-and-dash line after folding and binding to a required thickness.
