Bags are fed individually along a linear path from an upright bag pack by front vacuum cups and after the leading bag has been separated from the pack, rear suction cups are engaged with the back of the leading bag. The front and rear suction cups are moved away from each other to enable a bag gripper to be inserted in its upper end after which the front suction cups are swung out of the bag path, the gripper is moved to move the leading bag past the front suction cups, the front suction cups are then swung back into the bag path, the rear suction cups are swung out of the bag path and the front suction cups are moved toward the bag pack to extract the next bag from the bag pack.
