Sheets obtained from natural plant fibers, natural animal fibers, chemical fibers or combinations thereof are included.

[0002]

2. Description of the Related Art For example, in the case of obtaining a product such as a multi-folded map or a garment having a fold, conventionally, a sheet or cloth prepared in advance is manually creased,
Next, I had to manually fold along the fold line. For this reason, the folding work is extremely complicated, requires a long time, and causes a high cost of the product.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a thin body, a crease blade and a crease device which are extremely effective in simplifying, increasing the efficiency, automating and cost reduction of multiple folding work. is there.

[0004]

In order to solve the above-mentioned problems, the thin body according to the present invention includes a mountain fold fold and a valley fold fold. The mountain fold folds and the valley fold folds are processing marks on the front surface and the back surface,
They are arranged alternately and each has a zigzag pattern.

As described above, in the thin body according to the present invention, since the mountain fold fold and the valley fold fold are provided on the front surface and the back surface, the mountain fold fold and the valley fold fold are provided on only one side. The operation of bending the thin body on the front surface and the back surface is very easy, unlike the case of providing the thin body. Also,
It is possible to avoid damage when folded.

In the thin body according to the present invention, since the mountain fold folds and the valley fold folds are processing marks, the operation of bending the thin body on the front surface and the back surface is extremely easy. In the present invention, the processing mark refers to a mark formed on the front surface or the back surface of the thin body by a mechanical means such as a press. Moreover, since the mountain fold folds and the valley fold folds are alternately arranged, they can be folded by a folding operation.

Further, since each of the mountain fold fold and the valley fold fold has a zigzag pattern, the thickness of the thin body which is overlapped when folded is absorbed by the zigzag angle, and the fold can be surely performed. The zigzag angle is preferably selected to be 1 second or more and 15 degrees or less. In this angle range, in many cases, the overlapping of the thickness due to folding, absorption, and reliable folding are possible.

The thin body according to the present invention can include, as a preferred embodiment, a second mountain fold fold and a second valley fold fold. The second mountain fold fold and the second valley fold fold are provided between the mountain fold fold and the valley fold fold. The second mountain fold fold is continuous with the mountain fold fold and is discontinuous with the valley fold fold. The second valley-fold fold is continuous with the valley-fold fold, and is discontinuous with the mountain-fold fold.

According to the thin body of this aspect, the thin body is alternately folded at the mountain fold fold and the valley fold fold, and then the second mountain fold fold and the second valley fold fold are formed. At the fold portion, it is possible to fold in a direction intersecting the mountain fold fold and the valley fold fold. Therefore, folding and folding operations are extremely easy.

Moreover, the second mountain fold fold is continuous with the mountain fold fold and is discontinuous with the valley fold fold,
Since the second valley-folding fold is continuous with the valley-folding fold and is discontinuous with the mountain-folding fold, it is possible to prevent the thin body from being broken at the fold.

The present invention further discloses a creasing blade and creasing apparatus suitable for obtaining the above-mentioned thin body.

FIG. 28 is a view showing another embodiment of the creasing blade according to the present invention. The feature of this embodiment is that the blade tip 134, the second blade tip 136, the concave groove 135 and the second concave groove 137 are formed on the surface of the plate-shaped substrate 11 made of metal or plastic. Edge 134 and groove 13
5 has a zigzag pattern of angles α51 and α52. The second cutting edge 136 is continuous with the cutting edge 134, and the groove 5
Are spaced apart from each other by a distance ΔG31 and are discontinuous with the groove 5. The second groove 137 is continuous with the groove 135, but is separated from the cutting edge 134 by a distance ΔG 32, and thus the cutting edge 1
34 is discontinuous.

The scoring blade shown in FIG. 28 is wound around a drum to form the scoring blade shown in FIGS. 24 and 25, or the scoring device shown in FIGS. 26 and 27. Can be configured.

[0071]

As described above, according to the present invention, there is provided a thin body, a crease blade and a crease device which are extremely effective in simplifying, increasing the efficiency, automating the cost and reducing the cost of multiple folding operations. be able to.
