Abstract
A bag opening apparatus and method for use in a bag filling and packaging machine using flat bags allow a bag to move to a subsequent step while being surely maintained in the state of having been opened. At a mouth opening step, the mouth portion of a bag is opened by using suction cups serving as a mouth opening device. Next, an abutting member of a bag bottom deforming device is moved upward to abut on the bottom of the bag, thereby deforming at least a part of the bottom inward of the bag, while restraining movement of a lower portion of the bag with retaining plates of a bag movement restraining device.
