METHOD OF FORMING CONTAINERS FOR AUTOMATED FILLING FROM A WEB OF FLEXIBLE MATERIAL

摘要

Flexible containers are produced by advancing a web of flexible material (10) through a sealing station where the web is sealed at spaced intervals to form a succession of container blanks (11) having in-line unsealed tops. The blanks (11) are severed from the web (10) as individual containers and then reoriented into mutually spaced, side by side position with their tops parallel one another above their bottoms. The container tops are then opened and advanced through a fill station (38) at a speed less than their speed of advance through the sealing station.
