The present invention relates to a round blade for a slitter and a slitting method for continuously cutting a long sheet-shaped object to be cut such as paper, metal foil, and metal thin plate.

を切断するスリッティング方法が知られている。2. Description of the Related Art Conventionally, two circular rotary round blades are piled up, and a thin plate-like material to be cut is formed at an overlapping portion of the first blade and the second blade. A slitting method for cutting an object is known.

利な剪断面にカッティングできることが知られている。In such a slitting method, a clearance corresponding to the shearing angle peculiar to the object to be cut (where the cutting edge of the first blade and the cutting edge of the second blade are the deepest) is formed at the overlapping portion of the first blade and the second blade. It is known that a sharp sheared surface can be cut with a small force by giving a distance between the cutting edge of the first blade and the cutting edge of the second blade in the overlapping portion.

た。However, in the conventional slitter, it is difficult to accurately arrange the circular blade so that a clearance of the order of sub .mu.m to several .mu.m can be set when the round blade is set.
A method of setting so that the round blades of one sheet come into contact with each other is adopted, but according to this method, the blade edges of both round blades come into contact with each other, so that the blade edges wear out early, and the life of the circular blade is short. At the same time, there is a problem that the cutting edge has poor sharpness and the cutting quality of the object to be cut is deteriorated due to the influence of the abrasion powder.

付与することができないという問題があった。However, according to the method of providing the clearance by the method described in Japanese Patent No. 319597, a predetermined stress is applied to the second blade in order to provide the clearance by the bending amount of the second blade. It is necessary to set a certain amount of clearance due to variations in the stress applied due to settings and variations in the thickness of the second blade, and changes in the amount of bending of the second blade due to fatigue after long-term use. There was a problem that it could not be applied accurately over a long period of time.
