Disclosed is an apparatus for cutting a paper pipe (10), wherein a paper pipe (10) is cut while rotating both a cutting blade (14) and the long paper pipe (10) in opposite directions to each other, in such a manner that rotational linear velocities of a cutting portion of the cutting blade (14) and a central portion in a thicknesswise direction of the paper pipe (10) are controlled to be within certain range. <IMAGE> |
