ABSTRACT:
An apparatus for successively opening the mouths of bags which are fed one by one to a table and putting such bag over a guide hopper for charging the bag with an article to be packaged. The mouth of the bag is sucked by a pair of vacuum suction members from the opposite sides. The vacuum suction members are gradually separated from each other while transferring a bag from a table to the hopper, thereby gradually opening the mouth of the bag. This prevents failures in opening bags and also prevents the bag from separating from the vacuum suction members.
