Abstract (en)
[origin: EP1787772A1] Torque necessary for cutting band-like paper is properly distributed to both of the preceding motor and the following motor, thereby making it possible to accurately cut the band-like paper. The cut off method for a cut off apparatus including: a preceding knife cylinder 2 on whose peripheral surface a preceding helical knife 4 is provided; a following knife cylinder 3 on whose peripheral surface a following helical knife 5, which cuts off band-like paper D in cooperation with the preceding knife 4, is provided; a preceding knife driving motor 12 which rotationally drives the preceding knife cylinder 2; a following knife driving motor 13 which rotationally drives the following knife cylinder 3; and a cut off control device 20 which individually controls the preceding knife driving motor 12 and the following knife driving motor 13, is characterized in that the method comprises : giving, when the band-like paper D is cut, the preceding knife 4 and the following knife 5 a specified amount of torque in the direction in which the preceding knife 4 and the following knife 5 are pressed against each other, by means of the preceding knife driving motor 12 and the following knife driving motor 13.
