ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to the art binding and more particularly to a do-it-yourself (DIY) based album and binding method therefor.
BACKGROUND OF THE INVENTION
DIY products have been popular among consumers. DIY has the benefits of satisfying consumers and reducing the manufacturing cost. For example, commercially available albums typically have predetermined pages. A consumer may buy one based on his/her needs such as one album for mounting pictures taken in a journey. However, this ideal album is not easy to find. In many cases, one has to buy an album with more pages than needed or buy several albums each having a small number of pages.
A conventional method for binding a desired plurality of leaves is shown in FIG.
1
. The binding process comprises the steps of a) aligning holes
101
,
111
, and
121
of front board
100
, leaves
120
, and back board
110
respectively; b) inserting female screws
140
through holes
101
,
111
, and
121
; and c) inserting male screws
130
to secure to female screws
140
.
But this is unsatisfactory for the purpose for which the invention is concerned for the following reasons:
1. Pages may recess toward the center of binding side. As such, pages may wrinkle.
2. Screws may loose or even get lost, thus causing pages to separate.
Another conventional method for binding a desired plurality of leaves is shown in
FIGS. 2 and 3
. The binding process comprises the steps of a) punching a projection
200
on one side of a leaf, a perforation
210
along the inner edge of projection
200
, a perforation
220
on the center of leaf parallel to perforation
210
, and a matingly shaped recess
230
on the other opposed side of leaf, b) folding projection
200
toward recess
230
with respect to perforation
220
; and c) repeating step a) and b) until a desired plurality of leaves are bound.
But this is still unsatisfactory for the purpose for which the invention is concerned for the following reasons:
1. It is required to register and adhere projection
200
to recess
230
in binding each leaf As such, 29 times of above process are performed in binding an album having 30 pages. In view of this, it is time consuming and tedious.
2. The quality of finished album depends mainly on the skill on an experienced worker. It is not reliable.
3. The original album may be messy after user adds additional leaves to the album.
It is observed by the inventor of the invention that paper is sensitive to temperature and humidity, and quality of paper is a key to a good album. In selecting leaf of album, the absorption of water of paper is a major concern. It is understood that paper with a low acceptable absorption of water may not cause curl, fold or damaged edges. Also, most albums do not provide fastening arrangement for mounting pictures. As such, the mounted pictures are messy in most cases. Even in albums having fastening arrangement and/or edge decoration, its design still suffered from a disadvantage. In detail, in such album color bands are stitched on three sides other than the binding side. But this requires a skilled worker to perform such job. However, a skilled worker may not be found easily.
Thus, it is desirable to provide a novel album and binding method therefor in order to overcome the above drawbacks of prior art.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an album binding method comprising the steps of a) preparing a plurality of leaves each having a projection one side and a matingly shaped recess on the opposed side; b) stacking the leaves on a base and aligning the projection of one leaf with the recess of the adjacent leaf; c) registering the aligned leaves; d) pressing the leaves with a platen; e) applying adhesive paste on the binding sides of the leaves; and f) removing the platen after the adhesive paste is cured.
It is another object of the present invention to provide an album binding method wherein the number of prepared leaves is based on individual needs, thus avoiding waste.
It is still another object of the present invention to provide an album wherein each page of the album has a plurality of holes arranged in rows and columns, resulting in a reduction of weight and strain of paper caused by the variation of temperature and humidity.
It is a further object of the present invention to provide an album wherein each page has a plurality of mounting spaces for mounting pictures. With this, the thickness of the album can be maintained the same.
