Abstract
A bag mouth correcting device is disposed between a deaeration station and a sealing station. The correcting device has a pair of bar-shaped guide members. The guide members extend in the direction of movement of a bag, and an expected sealing area of the bag passes between the guide members. The guide members are disposed at a height position corresponding to the expected sealing area. The guide members extend gradually upward and the space therebetween gradually decreases as the distance from the upstream side increases toward the downstream side in the direction of movement of the bag. While passing between the guide members, the tilted bag mouth is corrected to a substantially uncurled state.
