Claims

[Scope of utility model registration request]

A sliver that cuts a plate material inserted between two rotating shafts that rotate in opposite directions by interlocking the outer peripheral edges of circular blades attached to the outer peripheral surfaces of two rotating shafts arranged parallel to each other. A blade attachment device for a slitter that fixes a blade to the outer peripheral surface of a rotating shaft,
A short cylindrical shape having an inner diameter that can be freely fitted onto the rotating shaft without wobbling, and elastically deformable on the inner circumferential surface of the base body to which the cutter can be fixed on the outer circumferential surface. A state in which a pair of freely movable holding cylinders are provided, with a short cylindrical gap interposed between the outer circumferential surface of each holding cylinder and the inner circumferential surface of the base body, and liquid tightness maintained at both ends of each gap. A blade mounting device for a slitter, which is mounted on the slitter and is further provided with an oil passage that communicates the sealed gap with a pressure oil supply means.
