In a bag making machine for cutting plastic film with a Thomson blade (3), and manufacturing plastic bags, plastic film (1) can be cut with a Thomson blade (3) even if the Thomson blade (3) is not pressed against the plastic film (1) with great force. The Thomson blade (3) comes into contact with the plastic film (1) on one side in the thickness direction of the plastic film (1), and a rolling member (4) comes into contact with the plastic film (1) on the other side in the thickness direction of the plastic film (1), rolling and moving along the plastic film (1) and the Thomson blade (3). Thus, the plastic film (1) is held between the Thomson blade (3) and the rolling member (4), and the plastic film (1) is cut by the Thomson blade (3) and the rolling member (4), producing plastic bags. |
