Description

[Detailed description of the invention] The present invention relates to a binder and a method for manufacturing the same.

In particular, the back cover is made of metal and has a U-shaped cross section, the center of which is split in half and connected with a hinge, and the back cover is opened left and right by this hinge to open and close the binding fitting attached to the back cover. In a binder, the cover is made of cardboard, etc. as a core material, and a sheet of leather, cloth, vinyl, etc. is affixed only to the top surface of the pasted cover, and a metal part is connected to the spine with a hinge, and the metal part is This invention relates to a binder whose edges are folded back to cover the edges of a pasted cover, and a method for manufacturing the binder, which has a good appearance and feel and is easy to manufacture, and a method for manufacturing the binder.

To explain the figures, FIGS. 1 to 3 are explanations of conventional binders, and the one shown in FIG. A metal cover 1.1' is attached to the left and right sides of the cover with hinges 4 and 4', but this makes the entire cover made of metal, giving it an extremely cold feel.

FIG. 2 shows another example of a conventional binder, and FIG. 3 is a cross section taken along the line X-X in FIG. The entire surface of the material 7 is covered with a top sheet 8 made of leather, cloth, vinyl, or the like.

Bend the tip of the metal spine part 5 attached to the spine part 2 and 2' with a hinge 4, which has a joint such as a hinge 3', fit the above-mentioned cover 1 there, and attach it with the studs 6. .

With this binder, when creating a cover, all side edges of the cover are visible, so if you have to attach a sheet of leather, cloth, etc. to cover that edge, you have to attach each cover separately, which is a hassle. In addition, it has the disadvantage that the studs are visible and give it a rugged feel.

Figure 4 shows the binder of this invention, where the hinge joint 1
A binding fitting 13 is attached to the metal spine part 11, 11' which is divided into two halves at 2 (the two pieces together form a U-shape as shown in the figure), and a document 14 is bound thereto.

Then, the metal part 15 is connected to the spine part 11.11' by a hinge 17.

On the other hand, a cover sheet made of leather, cloth, vinyl, etc. is pasted only on the upper surface of a core material such as cardboard to form a cover sheet 16, and this cover sheet 16 is attached to the metal part with the cover sheet outside. 15, the edge of the metal part is folded back to cover the edge of the sticker, and the cover 10 is formed by combining both the sticker and the metal part.

5.6.7 is an explanation of the manufacturing process of this pasting cover part 16, and FIG. 5 shows a sheet covering the core material of the four autumn leaves of the cover, and FIG. This is a cross section taken along the Y-X line.

A sheet 19 is pasted from above onto a core material 18 such as cardboard, and the sheet is bent downward at edges 20 and 21 to cover the edges of the core material.

At 22° 23 of the upper and lower edges of the core material, the cardboard is visible without being covered by the sheet.

The bottom surface of the core material is not lined, and remains as the core material.

As shown in Figure 5, first attach the sheet to the core material that is twice the size of the vertical and horizontal dimensions of the cover (the core material is the size of the four autumn equinox on the cover), and then Then, cut it into quarters along lines AEB and CED, and use the separated pieces as the sticker section 16.

Then, as shown in FIG. 4, it is combined with the metal part 15 to form the cover 10.

That is, each of the cut-off mouth pieces is cut out along lines AE, CB, EB, and ED, as shown in FIG.

The core material is exposed at the upper and lower edges 22 and 23 where the sheet is not folded back, and the core material is covered only at the edges 20 and 21 by the folded sheet.

In other words, only one back edge of the four edges of the sticker section 16 is covered with the sheet, and the core material of the remaining three lines is visible at the cut edges.

When placed on the metal part, the edge covered by the sheet is brought to the side of the hinge 17, and the other three ends are folded back over the metal part and wrapped therein.

Also, with the sheet 19 facing outward, the side of the core material not covered with the sheet is placed against the metal part.

Therefore, the metal part 15 covers the core material of the sticker part from the back side.

This will give it a nice look and feel, and it will also allow you to make four covers just by pasting up the Autumn Equinox covers, and there will be no need for lining.

The present invention has such a structure, and provides a binder that reduces the number of steps required for manufacturing and has a good appearance and feel, and a method for manufacturing the binder.
