摘要： A cutter, simple in construction but having good cutting quality and durability, for cutting paper in a semicylindrically curled state. With radii equal to or approximate to the radius of curvature of the paper to be cut, a stationary blade having a semicircular receding contour and a movable blade having an at least semicircular extending contour are spring-biased into pressure contact edgewise. The distance between the centers of the blades is greater than the difference between the blade radii so that the movable blade can always move in contact at only one point with the stationary blade during cutting operation.
