ABSTRACT:
An apparatus for cutting a belt-shaped member includes: a lower blade; a cutter; a holder for supporting the cutter; a carriage for revolving the holder about an axis of revolution intersecting an axis of rotation of the cutter by maintaining a very small angle to the axis of rotation of the cutter; a revolving mechanism for revolving the holder about the axis of revolution to cause the cutter to undergo precession about the axis of revolution, a direction of inclination of the cutter being set such that, when the belt-shaped member is cut from one side toward other side of the lower blade, a side of the cutter on the other side of the lower blade is located closer to the lower blade, while when the belt-shaped member is cut from the other side toward the one side of the lower blade, a side of the cutter on the one side of the lower blade is located closer to the lower blade; and a moving mechanism for moving the cutter and the holder along the lower blade.
