Abstract
A bag mouth opening device for continuously conveyed bags including suction cups (16, 17) continuously rotated in mutually opposite directions along substantially symmetrical elliptical moving paths (24, 25) on ether side of a conveying path (1) for bags. The time the suction cups take to make their single rotation along the moving paths matches the time a bag (20) takes to be conveyed for an inter-bag distance(s). The major axes (26, 27) of both moving paths of the suction cups are inclined at almost the same angles relative to the conveying path and digress from the bag conveying path toward their anterior side.
