ABSTRACT:
There is disclosed a form, fill and seal apparatus for liquids, semi-liquids and powders. The apparatus contemplates the use of two films and the sloping of the first seal and filling station at from ten degrees to a vertical condition. Contrary to the many arrangements and apparatus showing a single film and fill apparatus, this application allows and encourages single and plural filling simultaneously of pouches formed in two films. The pouch is formed by a U-shaped seal that enables a longer seal time to be employed rather than the longitudinal sealing means often employed. The feeding tube is fixed in place and the package as it is formed and filled is advanced past the fill tube. The filled pouches have the sides bowed and/or skewed to accommodate insertion of the spout and fill contents. The open top of the formed and filled pouch, when moved from the spout, is brought from its bowed condition to a contiguous and wrinkle free condition whereat it is sealed.
