Claims

[Scope of utility model registration request]

a rotatable first circle cutter disposed on one side of the sheet-like member to be relatively moved with its axis perpendicular to the moving direction; a rotatable first circle cutter disposed on the other side of the sheet-like member; a rotatable second circle cutter that sandwiches the sheet-shaped member and slides in pressure contact with the outer peripheral side surface of the first circle cutter to cut the sheet-shaped member in the moving direction; A sheet-shaped member cutting device comprising a moving means for moving the cutter from an operating position where the cutter slides in pressure contact with the cutter to a rest position separated from the first circle cutter, in which the second circle cutter is connected to a driven helical gear. At the same time, a driving helical gear is provided that meshes with the driven helical gear when the second circle cutter is in the operating position, and the direction of inclination of the tooth surfaces of the driving and driven helical gears is The drive torque of the drive helical gear causes the second circle cutter to move to the first position.
A cutting device for a sheet-like member, characterized in that the thrust force is generated in a direction in which the thrust force is pressed toward the side surface of the circle cutter.
