Abstract

PROBLEM TO BE SOLVED: To minimize the space for cutting material to be bound by folding in a tongue-shaped piece along the notched part and thereafter adhering tape material to the material to be bound for preventing the tongue-shaped piece from coming into the notched part. SOLUTION: Material 1 to be bound is mounted on a binding table 6 to be disposed in its corner part to correspond with the lower part of a blade 3 of cutter material 2. Then, the cutter material 2 is pressed down in order that the material 1 to be bound is notched in an L-shape in conformity with the shape of the blade 3 from its surface, and then the blade 3 penetrated through the material 1 to be bound comes into a receiving hole 7. A tongue- shaped piece 9 is formed at the inside of a notched part 8. Next, tape material 10 is adhered to the material 1 to be bound so as to preclude the tongue-shaped piece 9 folded downward from entering in the notched part 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding method for binding paper, sheets, etc. without using staples.

[0002]

2. Description of the Related Art As a paper binding method for binding paper or the like without using staples, for example, a method disclosed in Japanese Utility Model Laid-Open No. 53-6124 is known. This is because a part of the material to be bound is cut into a U-shape, a V-shape, etc., and an opening is cut out in the vicinity thereof, and a portion remaining inside the cut-out portion is folded downward, and then this folded portion is further cut. It is folded back and inserted into the above-mentioned opening so as to be projected upward.

[0003]

However, in the above-described paper binding method, the folded material to be bound is further folded back and taken out from the opening portion. Therefore, the folding portion must be formed sufficiently long and the cutting portion In addition, since an opening for inserting the folded portion must be formed, it is necessary to increase the space for cutting the material to be bound.

Further, in order to further fold the notched portion and insert it into the opening, the structure of the binding device for carrying out the above-described binding method must be complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks and to provide a binding method capable of minimizing the space for cutting the material to be bound and simplifying the structure of the binding device.

[0006]

In order to solve the above-mentioned problems, in the method of binding paper or the like according to the present invention, a tongue-shaped piece is formed inside from the surface of a plurality of papers, sheets or the like to be bound. While making a notch, after folding the tongue along the notch, a tape material is attached to the material to be bound so as to prevent the tongue from entering the notch. To do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show a binding method according to the present invention. In FIGS. 1 and 2, reference numeral 1 is a material to be bound.
The binding material 1 may be paper or a synthetic resin sheet or the like.

First, an L-shaped cut is made from the surface of the material 1 to be bound, a cut is made so that a tongue is formed inside, and the tongue is folded along the cut. In this case, for example, a device as shown in FIG. 1 may be used. In the figure, 2 is a cutter member. Cutter member 2
Is bent in a substantially L shape, and an L-shaped blade 3 is formed at the tip. A push rod 4 is held by the cutter member 2 so as to be vertically movable, and the push rod 4 is constantly urged downward by a spring 5. A binding table 6 is arranged below the cutter member 2, and a receiving hole 7 for the blade 3 is formed in the binding table 6.

According to the above structure, the material to be bound 1 is bound by the binding table 6
It is placed on the upper side, and its corner portion is arranged below the blade 3 of the cutter member 2. Then, the cutter member 2 is pushed down by an appropriate means. As a result, the material to be bound 1 is cut into an L-shape from the surface according to the shape of the blade 3, and the blade 3 penetrating the material to be bound 1 enters into the receiving hole 7. A tongue 9 is formed on the inside of the cut portion 8. By the way, when the cutter member 2 is pushed down, the push rod 4 also moves downward at the same time, so that the tip of the push rod 4 hits the tongue-shaped piece 9, and when this is pushed down, the tongue-shaped piece 9 is folded along the notch 8 and the cutting piece 8 is pressed. It becomes like a) and (b).

The notch is not limited to the L-shape, as long as the notch has a shape in which the tongue is formed inside. Therefore, the shape of the blade 3 of the cutter member 2 is not limited to the L shape,
It may be U-shaped, V-shaped, C-shaped or the like.

Next, a tape material is attached to the material to be bound 1 so that the tongue piece 9 folded downward is prevented from entering the notch 8. For that purpose, for example, in FIG.
Like the adhesive tape 10 and the pressing rollers 11, 1
It suffices to use a sticking device provided with 2 and the cutter 13. In this case, while the adhesive tape 10 is hung from the device, the upper and lower rollers 11 and 12 are moved forward and the tongue-shaped piece 9 side end portion and the front and back surfaces thereof are attached with the adhesive tape 10 and the cutter is attached. The unnecessary portion may be cut off with 13.

As a result, the tongue piece 9 is formed as shown in FIGS.
Since the end portion of the adhesive tape 10 is arranged between the notch 8 and the notch 8, even if the tongue piece 9 tries to return to the inside of the notch 8 due to its restoring force, the notch 8 interferes with the notch. I can't get inside 8. Therefore, the bound state of the material to be bound 1 is reliably maintained.

The mode of the notch 8 may be as shown in FIG. 6, and in order to prevent the tongue-shaped piece 9 from entering the notch 8, the tape 10 material is attached as described above. Not limited to. For example, it may be attached as shown in FIG. 7 (a) or as shown in FIG. 7 (b).

As described above, according to the above-mentioned binding method, the notch 8 of the material to be bound 1 may be provided at one place, and the tongue 9 need not be further folded as in the conventional case. The length can be short. Therefore, the space for cutting the material to be bound 1 can be minimized.

Further, it is not necessary to fold back the tongue-shaped piece 9 and then insert the folded back tongue-shaped piece 9 into an opening different from the cut 8, and after the folding, the adhesive tape 10 is bound. It only has to be attached to 1.
A simple device structure is sufficient.
