The cutting device includes an upper blade rotation shaft to which a circular upper blade is attached and a lower blade rotation shaft to which a circular lower blade is attached. The upper blade rotation shaft and the lower blade rotation shaft are arranged in parallel, After the blade and the lower blade are brought close to each other, the upper blade and the lower blade are rotated to cut the belt-like material.

Cutting can be smoothly performed by adjusting the amount of lap (blade biting depth) between the upper blade and the lower blade in accordance with the thickness and type of the belt-like material. As a method for adjusting the amount of lap between the upper blade and the lower blade, there is disclosed means for moving the upper blade or the lower blade by a predetermined amount after detecting electrical continuity by contacting the upper blade and the lower blade (for example, , See Patent Document 1).

Hereinafter, materials constituting the present invention will be described. In addition, the material which comprises this invention can be used in any of the said Embodiment 1-2.

(Conductive member)
Any conductive member may be used without limitation as long as it has conductivity and elasticity. By having these properties, it is possible to perform zero-point alignment of the upper blade and lower blade without shortening the cutting life of the upper blade and lower blade, and to prepare for cutting of a strip that can adjust the lap amount A method and a method for cutting a strip can be provided.
As the conductive member, for example, conductive paper, a piece of wood or a fiber product, or a conductive polymer material can be used. Among these, it is preferable to use a conductive resin film as the conductive member. If it is a resin film, it will be difficult to generate dust and other dust even if the upper and lower blades are in contact with each other. Therefore, it is a belt-like material that requires a high degree of cleanliness (for example, optical applications such as optical films and optical sheets). Can also be preferably used.

The thickness of the resin film may be 100 μm or more, preferably 1 mm or more, and more preferably 5 mm or more. Although an upper limit is not limited, For example, it is 20 mm.
If it is less than the lower limit, the resin film is likely to be bent, and the zero point adjustment may not be performed properly.

The conductivity is not particularly limited as long as the electrical connection can be confirmed via the conductive member between the upper blade and the lower blade.

It is preferable to use a thermoplastic resin film as the resin film. This is because the conductive material can be easily dispersed.
As the resin film, a polyethylene terephthalate resin film, a fluororesin film, a high density polyethylene resin film, a polyphenylene sulfide resin film, a polyimide resin film, an acrylic resin film, a polyurethane resin film, or the like can be used. Among these, it is preferable to use a polyphenylene sulfide resin film from the viewpoint of excellent processing accuracy.

As the conductive material, for example, a conductive filler can be used in addition to a carbon-based conductive agent, graphite, tin oxide, titanium oxide, zinc oxide, nickel, aluminum, copper and the like.
Among these, it is preferable to use a carbon-based conductive agent. Since the carbon-based conductive agent is softer than metal materials and other conductive fillers, it is possible to reduce the occurrence of scratches on the upper blade and the lower blade. As the carbon-based conductive agent, for example, carbon black, carbon fibril, carbon nanotube or the like can be used.

(Upper blade, lower blade)
The upper blade and the lower blade can be used without limitation as long as they have conductivity and can cut a strip-like material. For example, high-speed steel, alloy steel, stainless steel, cemented carbide or the like can be used. As these materials, the upper blade and the lower blade may be used separately, or different materials may be used for each upper blade and each lower blade.
