BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a saddle stitch book in which the spines of a plurality of folded signatures are bound by a wire.

[0002]

2. Description of the Related Art Normally, as a binding process for a book having a relatively small number of pages such as magazines and catalogs, a saddle stitch book in which the backs of a plurality of folded signatures are bound by a wire is generally adopted. Has been done. The manufacturing process of such a saddle stitch book is shown in FIGS. FIG. 4 is a perspective view showing the entire saddle stitch book manufacturing process,
FIG. 5 is an enlarged perspective view showing the wire binding process in FIG.

In FIG. 4, A is a collating process, B is a wire stitching process, and C is a cutting process. In the figure, 11 is a gathering chain, 12 is a piece, and 13 is a center page signature (hereinafter called center page). , 14 and 15 are signatures,
16 is a cover signature (hereinafter referred to as a cover), 17 is a wire,
Reference numeral 18 is an upside down cutting blade, and 19 is a small edge cutting blade.

In the gathering step A, a plurality of signatures 13 to 16 forming a saddle-stitch book are supplied onto the gathering chain 11 in an open state, and the gathering chain 1 is fed.
1 is a sequence of signatures (13, 14, 15, 1
While pressing 6) with the piece 12, the plurality of signatures 13 to 16 are sequentially gathered. In the subsequent wire binding step B, the spine 21 of the assembly 20 (hereinafter referred to as a signature assembly) in which the plurality of signatures are aligned and aligned with each other is attached to the wire 17
After binding with, in the cutting step C, the upside-down cutting blade 1
The top and bottom make-up cutting is performed at 8, and the small-edge make-up cutting is further performed at the fore-edge trimming blade 19 to complete the production of the saddle stitch book 22.

Here, in the wire binding step B, as shown in FIG. 5, the wire 17 is formed into a U-shape by the stitcher 23 located on the gathering chain 11, and then the signature assembly 20 is formed. The wire 17 is pierced from the cover side to the spine 21, and the gathering chain 11
The clincher 24 located below is operated via the connecting rod 25, and the tip of the wire 17 protruding toward the center page is pressed against the peripheral surface of the clincher 24 to bend the tip of the wire 17 inward.

[0006]

In the saddle stitch book 22 produced by the above-described processing, as shown in FIGS. 6 to 8, the wire 1 is formed on the fold line portion 26 of the center page 13, that is, the throat.
The bent portion 27 of 7 is exposed. 6 to 8, (a) is a perspective view showing a state in which the saddle stitch book 22 is bound, (b) is a partially enlarged view of the binding portion of (a),
(C) is a perspective view showing the spread state of (a).

In the processing state of the wire 17 on the saddle stitch book 22 in the early stage, the wire 17 is bent inward in a semicircular shape as shown in FIG.
The leading end portion 28 of the paper was arranged so as to face the sheet of the center page 13. However, in the processing state of the wire 17, as shown in FIG.
When the reader opens the book, the semicircular bent portion 27 of the wire 17 is projected to the center page 13, and there are many problems such as poor appearance and easy catching. As shown in FIG. 7B, the wire 17 is processed by bending the wire 17 inward in a straight line, and the tip 28 of the bent portion 27 is directed in the direction in which the paper of the center page 13 is pierced. It is the mainstream that they are arranged so as to cover the center page 13 rather than face it.

However, in the processing form of the wire 17 shown in FIG. 7, the saddle stitch book 22 is placed at the center page 13 while the reader is subscribing.
When the paper is opened so as to be bent, the bent portion 27 of the wire 17 exposed on the center page 13 is lifted by the action of the tension of the paper and the like, as shown in FIG. There is a risk that the reader may touch the tip end portion 28 of the bent portion 27 and the fingertip may be injured. This tendency is particularly remarkable when the saddle stitch book 22 is thick or the material of the paper is hard, and recently the number of pages tends to increase in magazines and the like. It is requested to collect.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a safe saddle-stitch book in which the reader is not injured at the fingertip during the subscription. It is in.

[0010]

In order to achieve the above object, a saddle stitch book of the present invention is a booklet in which a plurality of signatures are gathered and their backs are bound by a wire, and an exposure in the wire. It is characterized by comprising a protective sheet for covering the bent portion, and specifically, there are the following three types.

The first type is a two-fold center page in which the bent portion of the wire is located at the throat of the middle-page spread page of the booklet and the protective sheet is separately prepared.
This center page is affixed to the throat of the central double-page spread with an adhesive. The second type is a two-fold cover in which the bent portion of the wire is at the back of the booklet and the protective paper is prepared separately, and the cover is attached to the back of the booklet with an adhesive. It is something that is worn. In the third type, the bent portion of the wire is in the throat of the center double-page spread in the booklet, the protective sheet is the center double-page spread, and the center double-page spread is attached in the vicinity of the throat. To form a bag part.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a procedure for making a saddle-stitch book of the first type. First, as shown in (a), a plurality of signatures 1 including a cover are gathered together, and then, as shown in (b), an assembly of the signatures 1 is arranged at two places from the front side toward the inside with a wire 2. When stopped, the booklet 3 is formed by binding the spine. The booklet 3 bound in this manner is in a state in which the bent portion 2a of the wire 2 is exposed at the fold line portion of the central double-page spread 1a, that is, the throat. Then, as shown in (c), the center double-page spread 1a of the booklet 3 is laminated on the center page 5 coated with the adhesive 4 (cold glue or hot melt) along the fold line. This makes booklet 3
The center page 5 folded in half is attached to the throat of the double-page spread 1a in the middle through the adhesive 4.

The saddle stitch book produced in this manner has the bent portion 2a of the wire 2 covered with the center page 5. Then, the bent portion 2 of the wire 2 by the adhesive 4
Since “a” is fixed, it is hard to lift up, and even if it is lifted up, it is unlikely to break through the center page 5 and be exposed to the outside. Further, since the bent portion 2a of the wire 2 is covered with the adhesive 4, even if the tip portion 2a of the wire 2 is exposed to the outside, the bent portion 2a
There is no chance that the reader will touch the tip of a and injure their fingertips. Further, since the fold line portion of the center page 5 is reinforced with the adhesive 4 and is not bound by the wire, the center page 5 is broken at the wire binding portion and falls off, or the center page 5 is broken at the fold line portion. It also has the effect of preventing quality problems such as center page breakage that occurs when a saddle stitch book is dropped. Further, since the center page 5 is a sheet of paper for two pages in which the wire 2 is not exposed in the center of the paper surface, the wire 2 is exposed when planning an advertisement using a space for two pages in a spread page. Not doing so is an advantageous condition in terms of design, and there is also an effect of increasing the flexibility of such a project.

FIG. 2 shows a procedure for manufacturing a second type of saddle stitch book. First, as shown in (a), a plurality of signatures 1 excluding the front cover are gathered together, and then, as shown in (b), the assembly of the signatures is attached to the front cover side from the throat portion of the central double-page spread with a wire 2. The booklet 3 is formed by binding at the back by stopping at two points. In the booklet 3 bound in this way, the bent portion 2a of the wire 2 is exposed at the spine portion. Next, as shown in (c), an adhesive 4 (cold glue or hot melt) is applied along the spine of the booklet 3, and a cover sheet 6 folded in half is covered and bonded. As a result, the cover 6 is attached to the spine of the booklet 3 via the adhesive 4.

In the saddle stitch book produced in this manner, the bent portion 2a of the wire 2 is on the side opposite to the normal saddle stitch book, that is, not on the throat side but on the cover side, and the bent portion 2a is further formed. It will be covered by the cover sheet 6. In this saddle-stitch book, even if the reader unfolds so as to warp at the central double-page spread during the subscription, the tension of the paper applied to the wire 2 does not act in the direction to float the bent portion 2a, Wire 4 with agent 4
Since the bent portion 2a of the wire 2 is fixed and is hard to lift, the bent portion 2a of the wire 2 hardly rises. Even if the bent portion 2a floats up by some measure and its tip pierces the cover 6 and is exposed to the outside, since the bent portion 2a is covered with the adhesive 4, the reader touches the tip. There is no chance of injuring your fingertips. Further, since the fold line portion of the cover sheet 6 is reinforced with the adhesive 4 and is not bound by the wire,
It also has an effect of preventing quality troubles such as spine cracks in which the cover sheet 6 is broken at the fold line portion and falls off.

FIG. 3 is a schematic view showing a saddle-stitch book of the third type as viewed from the top and bottom. This saddle stitch book is shown in Figure 1.
Similarly to the case shown in (a) and (b), the signatures 1 including the cover are gathered together, and the back portion thereof is bound with the wire 2, and then, in the vertical direction near the throat of the central double-page spread 1a. The adhesive is applied in a straight line to form the bag portion 7, and the central double-page spread 1a is attached.

In the saddle stitch book produced in this manner, the bent portion 2 of the wire 2 is hidden by the bag portion 7. Since the bag portion 7 has a slight margin, even if the bent portion 2a of the wire 2 is slightly lifted, the tip of the bent portion 2a of the wire 2 is not covered by the bag portion 7.
There is no such thing as breaking through and jumping out.

[0018]

As described above, in the saddle stitch book of the present invention, the bent portion of the wire is covered or hidden by the protective paper, and the bent portion of the wire is lifted to the outside. The exposure is prevented and the reader's fingertips are not injured.
