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 and the like 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 Patent Application 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 and the like, and an opening is cut out in the vicinity thereof, and a portion remaining inside the cut portion is folded downward, and then the folded portion is further folded. It is folded back and inserted into the above-mentioned opening so as to come out upward.

[0003]

However, in the above-described paper binding method, the folded material to be bound is further folded back to be taken out of the opening, so that the folded portion must be formed sufficiently long and the cut portion must be formed long. 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 cut portion and insert the cut portion into the opening, the configuration of the binding device for performing the above-described binding method must be complicated.

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

[0006]

According to the present invention, there is provided a method for binding paper or the like according to the present invention, wherein a tongue-like piece is formed inside a surface of a material to be bound such as a plurality of papers or sheets to be bound. A cut is made so that the tongue is folded along the cut, and then a tape material is attached to the material to be bound so as to prevent the tongue from entering the cut. I do.

[0007]

1 shows a binding method according to the present invention. In FIGS. 1 and 2, reference numeral 1 denotes a material to be bound.
The material to be bound 1 may be paper or a sheet made of synthetic resin.

First, an L-shaped cut is made from the surface of the material 1 to be bound, and a cut is made so that a tongue is formed inside, and the tongue is folded along the cut. In this case, for example, the apparatus shown in FIG. 1 may be used. In the figure, reference numeral 2 denotes a cutter member. Cutter member 2
Is formed 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 configuration, the material to be bound 1 is bound to the binding table 6.
The cutter member 2 is placed so that its corners correspond to the lower side of 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 thereof according to the shape of the blade 3, and the blade 3 that has penetrated the material to be bound 1 enters the receiving hole 7. A tongue 9 is formed inside the cut 8. By the way, when the cutter member 2 is pushed down, the push rod 4 also moves down at the same time, so that its tip hits the tongue-like piece 9, and when this is pushed down, the tongue-like piece 9 is folded along the cut 8, and FIG. a) It becomes as shown in (b).

The cut has only to have a shape in which a tongue-like piece is formed inside, and is not limited to an L-shape. Therefore, the shape of the blade 3 of the cutter member 2 is not limited to the L shape, either.
It may be U-shaped, V-shaped, C-shaped, or the like.

Next, a tape material is adhered to the binding material 1 so as to prevent the tongue-like piece 9 folded downward from entering the cut 8. For this purpose, for example, FIG.
, The adhesive tape 10 and the pressing rollers 11, 1
2 and a cutter 13. In this case, the upper and lower rollers 11 and 12 are advanced while the adhesive tape 10 is hung from the above-mentioned device, and the adhesive tape 10 is attached to the folded end of the tongue-shaped piece 9 and the front and rear surfaces thereof. Unnecessary portions may be cut off by 13.

As a result, as shown in FIGS.
Since the end of the adhesive tape 10 is disposed between the notch 8 and the notch 8, even if the tongue-like piece 9 tries to return into the notch 8 due to its return force, the adhesive tape 10 hinders the cut. 8 can not get inside. Therefore, the binding state of the material to be bound 1 is reliably maintained.

The mode of the cut 8 may be as shown in FIG. 6, and in order to prevent the tongue-shaped piece 9 from entering the cut 8, the tape 10 is attached as described above. It is not limited to. For example, it may be attached as shown in FIG. 7A or may be attached as shown in FIG.

As described above, according to the above-described binding method, the cut 8 of the material 1 to be bound only needs to be formed at one location, and the tongue-like piece 9 does not need to be folded back as in the prior art. The length may be short. Therefore, the space for cutting the material to be bound 1 can be minimized.

Further, there is no need to fold the tongue-shaped piece 9 after folding it, or to insert the folded tongue-shaped piece 9 into an opening different from the cut 8, and after folding the adhesive tape 10 to the material to be bound. Since it only needs to be attached to 1,
A simple device structure is sufficient.
