Abstract
A method and device for opening spout attachment portion of a bag being set up such that films on both sides of a spout attachment portion () of a bag () are suction-held up by a pair of suction cups (), and the spacing between the pair of suction cups is widened to open the spout attachment portion, after which a gas is blown from the spout attachment portion into the bag by a gas blowing member (); and when the gas is blown into, a clamping member () clamps a position under the gripper that is on the top edge () side of the bag from both sides of the bag, thus suppressing outflow of the gas blown into the bag from the top edge, thus allowing entire bag to inflate for its entirety substantially and the spout attachment portion to be kept opened.
