Description

[Detailed Description of the Invention] This invention relates to a file in which a binding fitting is attached to the spine of the file, in which the head of the caulk for attaching the binding fitting to the outside of the spine of the file does not protrude, and a method for manufacturing the same. .

For ordinary files, the binding seat plate is placed on the inside of the spine and crimping is done from the inside and outside of the spine, so the head of the crimping sticks out on the outside of the spine of the file, making the product look stiff. To avoid devaluing the book, they would hide it by pasting a heading on its back.

Methods of manufacturing files in which the crimping head does not protrude outside the spine have also been considered, but these methods are complicated and time-consuming.

A conventional example will be described with reference to the drawings. In FIG. 1, cardboard is cut to the size of a file cover to form a front cover 1, a back cover 2, and a back cover 3.

Then, as shown in FIG. 2, a cut-out hole 5 having a cut-out piece 6 is provided in a plated iron plate 4 of the same size as the spine 2 at a position where the binding fittings are to be caulked.
Paste on the inside of the spine.

FIG. 3 shows an enlarged view of the hole, in which a cut-out hole 5 having a cut-out piece 6 is drilled in the iron plate 4, and a hole γ into which a caulking piece described later is inserted is bored in the cut-out piece. .

All front views are assumed to show the inside surface of the cover.

Then, a backing sheet 8 with holes 9 corresponding to the positions of the holes 5 as shown in FIG. Add stripes 10 and 10 at the borders of the front cover, spine, and back cover, respectively.

(It goes without saying that the required cover sheet is attached to the outer surface of the cover.

) Then, as shown in FIG. 6, the cut-and-raised piece 6 is raised upward with a tool or the like, and the acid caulk 11 is forcefully inserted into the hole 7 from below.

Then fit the binding fittings onto it and swage it from above with a male swage.

This method is not only complicated and time-consuming, but also
This is done by gluing the lining sheet 8 which has been opened and pasting it on the cover of the file and the iron plate 4. Therefore, when working with a machine, when pressing the lining sheet 8 onto the file with a roller, There is a disadvantage that the glue protrudes from the hole 9 and adheres to the roller, and the glue is deposited on the surface of the next backing sheet.Furthermore, the crimping of the binding fittings is done by connecting the iron plate 4 attached to the inside surface of the spine with the binding fittings. Since this was done only in the middle, there was also the drawback that the iron plate 4 could be peeled off from the spine 2.

Furthermore, since the cut-and-raised piece 6 of the iron plate 4 is forced up and inserted in order to insert and fit the female caulk, there is also the drawback that there is a lot of looseness even when the fastening fitting is attached.

As described above, conventional methods cannot avoid many drawbacks.

Therefore, in the file of this invention, as shown in FIG.
Caulk the acid swage, cover the head of the swage on the outside surface of the spine (the side opposite to the side that is visible in the diagram), stick a 22° piece of cardboard the size of the spine, and attach it to the inside of the spine. The metal fittings are fixed by attaching a male caulk to the clasp.

In this way, since the cardboard is soft, the head of the acid caulk that was swaged from the outside of the spine will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swaging will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swaging will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swage will be buried in the cardboard 22, and the head of the acid swaging will be buried in the cardboard 22. ) will be smooth, and if a cover sheet is pasted onto the outer surface of the cover, the crimping head will be completely invisible from the outside.

To further explain in detail how to manufacture this file, as shown in Figure 7, for example, the front cover 1 made of cardboard.
, the spine 2 and the back cover 3, holes 21 are made at required locations on the spine 2, and female caulks are caulked from the outside to the inside of the spine.

That is, the acid caulking opens inward.

A piece of cardboard 22 the size of the spine is then applied to the outside of the spine using a iron and adhered.

Cardboard is soft, so use the cardboard 22 for the swage head.
The outer surface of the spine (ie, the outer surface of the cardboard 22) becomes smooth.

(In this case, it would be better if the part of the cardboard 22 where the crimping head will be slightly depressed is made.

) Then, if a cover sheet is applied all over the outer surface of the file cover, the crimping head will be completely invisible from the outside, and will not be noticeable to the touch.

Next, a perforated backing sheet 23 is attached to the inside surface of the file, and a score line 24 is added at the boundary between the front cover, spine, and back cover as shown in FIG. 8.

The leg part that forms the opening of the acid swage is swaged so that it is almost flush with the surface of the cardboard, so the backing sheet can be applied neatly without interfering with gluing.

Since there are no holes in this sheet, the adhesive can be applied neatly without leaking out even when pressed with a roller for application.

Then, drill a hole where the acid caulking is.

Since the center of this hole punching and the above-mentioned pressing can be determined by positioning from the edge of the cover, it is easy to determine the caulking position that is symmetrical to the center.

This hole may be made by any method, but it can be easily made using a tool as shown in FIG. 9, for example.

That is, as shown in FIG. 9, needles 31 are implanted below the plate 30, corresponding to the relative caulking positions, and if the position of the hole is searched and pressed down from above with an appropriate mechanism, the back can be removed. A hole can be made at the caulking position on the tension sheet 23.

Then, place the binding fitting inside the spine cover, and attach the male swage to the acid swage to fix the binding fitting to the spine cover.

The present invention provides a file having such a structure, and a file with a beautiful appearance and high commercial value, in which the head of the acid caulk for attaching the fastener is completely invisible from the outside, and a method for manufacturing the file.
