Abstract
A multiple bag forming and filling apparatus and method utilizes a plurality of filling tubes which have a cross-sectional width in the range from one-third to one times the width of the tubular preform between the vertical seals at the filling tube means. There is also disclosed the directing of horizontally adjacent vertical tubular bag preforms to opposite sides of a center sealing bar prior to forming transverse seals by movable seal bars on the opposite sides. The horizontal displacement of the horizontally adjacent bags prevents the adjacent bags from being sealed together.
