DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for binding sheets in a bookbinding process for books, albums and the like, and more particularly, to a method for attaching a sheet to a surface of a sheet between opposing surfaces of adjacent sheets. The present invention relates to a binding method for forming a predetermined interval for absorbing the thickness of a worn photograph or the like.

[0002]

2. Description of the Related Art As is well known, a method called perfect binding is employed as a method of binding sheets in a bookbinding process of a photo album or the like. In this method, as shown in FIG. 3, the paper sheet 7 is folded in two at the center, and the outer surfaces of the paper sheets 7, 7 adjacent to each other are adhered to each other, whereby a plurality of paper sheets 7, 7,.・ It has the advantage that two pages of a spread can be viewed in a continuous state without a break, and the advantage that it is easy to open two pages of a spread horizontally. ing.

[0003]

In the book bound by perfect binding as described above, when the book is closed, almost no gap is formed between the opposing surfaces 7a of the paper sheet 7. Therefore, there is a problem that the book swells when a photograph or the like is pasted on the surface of the paper sheet 7.

Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a method of binding sheets in a bookbinding process in which a book does not expand even if a photograph or the like is pasted on the sheet. It is a thing.

[0005]

In order to achieve the above object, according to the present invention, as shown in FIG. 2, a paper sheet 2 is formed by overlapping a sheet member with a double sheet member. The connecting piece 3 made of a member is
2 and a bonding portion 3 of the connecting piece 3 with the back-tightened side edges 2a, 2a across the back-fastened side edges 2a, 2a.
a, 3a are adhered so as to be sandwiched between sheet members forming the paper sheet 2, and the stiffened side edges 2 of the paper sheet 2
a, a predetermined interval t is formed between the opposing surfaces of the paper sheets 2, 2 adjacent to each other by expanding a in the thickness direction, wherein the paper sheets are bound in the bookbinding process. Is the way.

The connecting pieces 3, 3,... May be integrally connected. In this manner, the paper sheets 2, 2,... Are arranged at predetermined intervals in the thickness direction, and all the connecting pieces 3, 3,. Since it can be attached to the side edge 2a, there is an advantage that workability is improved.

The paper sheet 2 may be formed by laminating two sheet members, or may be formed by bending one sheet member along a fold line and superposing a portion defined by the fold line. May be formed.

[0008]

When a book is closed by attaching a photograph or the like to the surface of the paper sheet 2 and the book is closed, an interval t formed between the paper sheet 2 and the opposing surface of the paper sheet 2 is set.
As a result, the thickness of a photograph or the like is absorbed, so that the book does not swell.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIGS. 1 and 2 show a book 1 bound by a sheet binding method according to the present invention.
Is a front view of the book 1 in an open state, and FIG. 2 is a bottom view of the book 1. In this embodiment, the book 1 is a graduation album, and has a plurality of paper sheets 2 and connecting pieces 3.

In the present embodiment, as shown in FIG. 2, the sheet 2 is formed by folding a rectangular sheet member made of cardboard into two along a fold line provided at the center, and superimposing two portions defined by the fold line. FIG. 1
As shown in the figure, the photograph 4 is printed on the surface in advance. The paper sheet 2 may be formed by stacking two sheet members.

In this embodiment, as shown in FIGS. 1 and 2, the connecting piece 3 is formed by forming a single band of paper into a bellows shape. The connecting piece 3 extends over the buckling side edges 2a, 2a of the paper sheets 2, 2 adjacent to each other, and the bonding portion 3a of the connecting piece 3 with the bucking side edges 2a, 2a of the connecting piece 3,
3a is affixed so as to be sandwiched between sheet members forming the sheet 2, and depending on the thickness of the connecting pieces 3, 3 sandwiched between the sheet members, the back side edge 2a of the sheet 2
Bulges in the thickness direction, thereby forming a predetermined interval t between the opposing surfaces of the paper sheets 2 and 2 adjacent to each other.
Note that this interval t absorbs the thickness of the sheet-like material 5 when the sheet-like material 5 such as a photograph is stuck to the margin of the paper sheet 2,
The size is set so that the album book 1 does not expand.

Then, the bound sheets 2, 2,...
Is decorated, decorated, and the bookbinding is completed.

In the book bound by the sheet binding method according to the present invention, since the bonding portion 3a of the connecting piece 3 with the sheet 2 is sandwiched between the sheet members forming the sheet 2. The connecting piece 3 is inconspicuous. Therefore, as in the case where bookbinding is performed by perfect binding, two facing pages can be viewed in a continuous state. Also, as with the case of perfect binding, it is easy to open two pages of a book horizontally so that the book has low resistance when opening the book.

The sheet-like material 5 to be adhered to the margin of the paper sheet 2 may be something other than a photograph, and may be anything as long as its thickness can be absorbed by the interval t.

Further, in this embodiment, a photograph is printed on the paper sheet 2. However, something other than the photograph may be printed or a blank paper may be used. Further, the paper sheet 2 may be a mount on which a photograph or the like is attached.

Also, one sheet member is bent along a fold line, and two parts defined by the fold line are superimposed on each other.
a, and the sticking portion 3a of the connecting piece 3 may be inserted between the sheet member and the adjacent sheet member. In this way, as in the case of the perfect binding, the two portions divided by the folding line become two-page spread, and there is no break between the two-page spread, which is preferable when printing a photograph or the like over two pages. .

[0017]

According to the present invention, the thickness of a photograph or the like attached to a paper sheet is absorbed by the space formed between the opposing surfaces of the paper sheets adjacent to each other, so that the book does not expand. Having.

When the method for binding sheets according to the present invention is applied to bookbinding of a book in which a photograph or the like is printed in advance, such as a graduation album, each of the sheets is added to the margin of the sheet. Because people can paste desired photos etc.,
It has the advantage that it can be finished into a book with individuality.
