ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a structure of a front cover for an album, a scrapbook and the like having intervals between cardboards wherein heat-soluble adhesive are used, and hollow-backed binding using a foresaid front cover.
2. Description of the Prior Art
There already exist an album, a scrapbook and the like bound with intervals between cardboards using heat-soluble adhesive. For example, a cardboard book disclosed in Japanese Utility Model Official Gazette No. S63-25176 has a structure comprising a cover body having a cover portion a, a cover portion b and a spine portion c, a plurality of cardboards d positioned as shown in
FIG. 5
having intervals equivalent to a predetermined thickness of a cardboard, and in the vicinity of an edge at a binding side of the plurality of cardboards, heat-soluble adhesive e intervening between cardboards to keep the intervals and gluing an edge surface of the edge at a binding side of the plurality of cardboards to an inside of the spine. Types of cardboards vary in applications from for a photo album, a postcard album, a stamp collection book, a coin collection book to a scrapbook.
Owing to such cardboard book, a bound book having intervals between cardboards is easily obtained at low price. Also an album, wherein an end of an album does not exceed a width of a spine even if a binder insert gets thicker by placing pictures on a binder insert, can be offered.
However, a backstrip of a cardboard (an edge portion at a binding side) comparatively becomes pliable because of a structure of such bound book having intervals between cardboards using heat-soluble adhesive. Therefore, the cardboard could not be used in conventional binding methods such as round-arch-spine binding and hollow-backed binding, wherein a hard backstrip is required. For the reason above, under the present condition, only bound books of low cost have been commercialized such as a handy-binding-type album, wherein a binder insert is directly adhered to the squarish spine.
An album has an essential product character, which is to store and keep photographs and other memorials for many years. For that reason, gorgeous and luxurious types of albums are required as well as low price and handy types thereof. A problem has been pointed out that a product of earnest binding type such as round-arch-spine binding and hollow-backed binding cannot be provided with the structure described above.
Here round-arch binding are further explained. According to conventional round-arch binding, a backstrip of a binding object is shaped into a round and then a cover is covered along therewith. Not that a backstrip of a binding object is formed in accordance with a round-arch-spine, but that a spine has to be shaped into a round to suit the backstrip of the binding object. Accordingly, cardboards having intervals therebetween and hinged binder inserts for an album are difficult in binding and impossible to use in round-arch binding.
The present applicant previously filed a Japanese patent application No. 2000-146408, wherein a spine affiche is resinous synthesis paper and heat-formed to obtain a round-arch binding. However, a spine of a bound book produced by this technology is fixed, which indicates that a problem of difficulty in turning over to double spread still remains unsolved.
SUMMARY OF THE INVENTION
In the view of the problem, the present invention provides a cover suitable for hollow-backed binding in binding having intervals between cardboards using heat-soluble adhesive and allows to obtain a well-bound appearance easily at low cost by suggesting a binding method using the cover. Also, the present invention has a purpose to provide an album, which is luxurious in appearance, easy to turn over to facing pages and easy to use.
To solve the each problems, the invention described in claim 1 adopts a structure comprising a decoration cloth, a pair of substratum paper and a spine affiche adhered on a predetermined position in a back surface of the decoration cloth, an interconnected reinforcement paper adhered on substratum papers of right and left to form space between a spine affiches and a reverse paper sheathing a back surface of the cover.
As space is formed between a spine affiche and an interconnected reinforcement paper, a cover of the above structure can be hollow-backed binding with the space after binding.
The invention described in claim 2 adopts a binding method having a process of adhering a plurality of cardboards, wherein heat-soluble adhesive are applied on a binding side thereof, to a back surface of a spine of a cover described in claim 1 while the plurality of cardboards have intervals therebetween, a process of keeping a cover, which is closed, at a room temperature, a process of bulging and rounding a spine portion by stressing from ravine portions of right and left outside of a cover in the middle of a state that heat-soluble adhesive is consolidating, and a process of consolidating the heat-soluble adhesive completely by fixing and holding the same until cooled down to a room temperature.
According to the above binding method, a bound book with a round-spine is obtained by an eminently simple process. Also, as a spine affiche and an interconnected reinforce paper is not adhered together in the cover, a bound book is able to have a round-spine meanwhile being a hollow-backed binding. Therefore, a well-bound appearance can be obtained easily at low cost and a luxurious album can be produced. Moreover, an album, which is easy to turn over and to see facing pages can be provided with hollow-backed binding.
