Abstract

A valve sack is made from tubular material whose opposed longitudinal edges have been gusseted. There is formed in one of the gussets an aperture (S) which extends along the gusset for a distance appreciably less than the width (D) of eventual sack. The outer longitudinal edges of the gusset are then sealed together, either directly or via a further sheet of material, over a distance greater than the length of said aperture, to form a tube running along one longitudinal edge of the material. The material is then sealed together along two lines which run across the material and are spaced apart to define the width of the eventual sack. One end of the tube is sealed off. A further aperture overlapping the first mentioned aperture if formed in the tube. [EP0002326A1]
