Abstract
A method of opening a bag mounted on a tape includes the steps of providing a bag including a first panel, a second panel, a first bag edge, a second bag edge, a bag bottom, and a bag mouth; gripping the bag between a first means for vacuumizing and a second means for vacuumizing; and moving the first and second means for vacuumizing such that the bag disengages from the tape, and the bag mouth opens. The first and second means for vacuumizing are activated before or during the gripping step, or after these means have been moved, but before the bag mouth opens. An apparatus for transporting a bag, and loading a bag, are also disclosed.
