摘要:
A cutting apparatus comprises a cutter roll (2) and an anvil roll (3), and a strip-like body of absorbent articles fed between the cutter roll (2) and the anvil roll (3) is cut into cut portions by blades (2e) provided on the cutter roll (2). The cutter roll (2) has circumferential ports formed in the circumferential surface thereof and a side port formed in one side surface thereof. A positive/negative pressure manifold (6) has a positive pressure port and a negative pressure port formed in one side surface thereof. The positive/negative pressure manifold (6) is so fixed that the one side surface thereof faces the one side surface of the cutter roll (2). When the side port is communicated with the negative pressure port, a negative pressure is applied into the circumferential ports causing the cut portion to be held by the cutter roll (2) and when the side port is communicated with the positive pressure port, a positive pressure is applied into the circumferential ports causing the cut portion being held to separate away from the cutter roll (2). A slight gap is formed between the one side surface of the cutter roll (2) and the one side surface of the positive/negative pressure manifold.
