JPS5823239B2 - File and its manufacturing method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a file, and particularly to a file having a slight depression above the spine and a method for manufacturing the same.

Conventional files were secured by attaching a binding tool to the inside of the spine, caulking an acid swage from the outside of the spine, and then inserting a male swage from the inside, so the head of the acid swage was visible from the outside of the file, making it feel stiff. and lowered the value of the product.

Furthermore, since the outside of the spine was flat, the metal fittings for inserting the heading paper protruded out, which not only spoiled the appearance, but also caused problems such as the metal fittings for inserting the heading paper getting caught.

This invention solves all of the above-mentioned drawbacks at once, and in this invention, a hole is made in the spine of the file, an acid caulk is caulked from the outside, and the acid caulk is planted from the inside to fix the binding fittings. Attach another piece of cardboard the size of the spine to the outside of the spine, covering the head of the acid swage, and leave a - hole in the upper part of the cardboard to form the spine heading. The present invention relates to a file in which a cover sheet is attached to the outer surface of the cover, and a method for manufacturing the same.

To explain the figures, Fig. 1 shows the appearance of the file of this invention before it is covered with a cover, and Fig. 2 shows the unfolded file seen from the inside of the cover. , create front cover 1, spine 2, back cover 3,
A small hole 6 was made in the spine 2, an acid caulk for attaching the binding fittings was caulked from the outside, and a window hole 5 for forming the spine heading section was cut out on the outside of the spine at the upper center as shown in Figure 1. Attach paper-sized cardboard 4 to cover the head of the acid caulk.

In FIG. 2, the cardboard 4 is pasted on the back side of the figure.

Then, from above, a front sheet 7 is attached to the outer surface of the cover, and a backing sheet is attached to the inner surface, thereby creating a file as shown in FIG. 3.

Since this file has such a structure, the head of the acid swage is buried in the cardboard 4, and the head of the acid swage is completely invisible from the outside.

A recess 8 is formed above the center on the outside of the spine 2 to accommodate the window 5 for forming the spine heading section of the cardboard 4.

Therefore, if the metal fittings 9 for inserting the heading paper are installed in the four parts 8 as shown in Fig. 4, the metal fittings will sink into the recess and the spine surface will be flush, giving a good appearance and preventing it from getting caught on the metal fittings. -become.

In addition, a heading paper holding piece made of vinyl or the like may be used instead of a metal fitting to insert the heading 2 paper, but conventionally, when the spine and cover width are relatively narrow, such as the guide length of the second figure, the heading paper holding piece is used instead of a metal fitting. A method was used in which both sides of the piece 10 were welded to the front cover and the back cover at the portions indicated by 11, straddling the spine.

In this case, to insert the heading page number, open the cover,
A gap was created between the spine and the holding piece 10, allowing the entry sheet to be inserted easily, but this was useful when the spine was relatively narrow; It was difficult to do.

In the file of this invention, if the heading paper holding piece 10' is welded at the parts 11' on both sides of the recess 8 as shown in FIG. Can it be easily inserted into the inside of the holding piece ≦ No matter how wide the spine is, the method of the present invention allows for more details about the manufacturing method that makes use of relatively small heading force. To explain, as shown in Figure 2,
Make a cover of the file with cardboard etc. from the front cover 1, spine cover 2, and back cover 3, make a small hole 6 at the desired position on the spine cover, and screw it in from the outside of the spine inward. A cardboard 4 of the size of the spine with a window hole 5 is pasted on the outside of the spine, a facing sheet 7 is pasted on the outside of the cover, and a lining sheet with no holes is pasted on the inside. Paste it on one side.

Even if a roller is used for this adhesion, since there are no holes in the backing sheet, there will be no drawbacks such as glue spilling out and sticking to the roller.

Backing: After pasting the sheet, the front cover, back cover,
Make a score on the border of the back cover, then use any method to make a hole at the female swage, insert a male swage, and secure the binding fittings.

This invention has such a structure, so that the edges of the edges and edges are not completely visible from the outside, and the inserting fitting for the heading paper is flush with the spine, or even when the fitting is not used, the inserting fitting for the heading paper is not visible from the outside. A file that is easy to insert and a method for manufacturing it are obtained.
