<p><P>PROBLEM TO BE SOLVED: To restrain erroneous cutting caused by thermal expansion of a holding roll. <P>SOLUTION: A cutting device includes a cutter roll 2 and an anvil roll 3, wherein an absorbent article band body fed between the cutter roll 2 and the anvil roll 3 is cut into a cut portion by a blade 2e provided on the cutter roll 2. The cutter roll 2 includes a peripheral port on a peripheral surface thereof, and a side port on one side surface thereof. A positive and negative pressure manifold 6 includes a positive pressure port and a negative pressure port on one side surface thereof. The positive and negative pressure manifold 6 is secured so that the one side surface of the positive and negative manifold 6 faces the one side surface of the cutter roll 2. When the side port communicates with the negative pressure port, the negative pressure is applied to the peripheral port, so that the cut portion is held by the cutter roll 2. When the side port communicates with the positive pressure port, the positive pressure is applied to the peripheral port, so that the cut portion which is held is separated from the cutter roll 2. A slight gap is provided between the one side surface of the cutter roll 2 and the one side surface of the positive and negative pressure manifold. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
