PACKAGING MACHINE WITH ROTARY TOP SEALER

摘要

A method of continuously forming, filling and sealing of packages with a continuous web of film material is disclosed and comprises the steps of providing a continuous web of film material and folding the web to provide confronting sides joined along a bottom edge and forming a vertical seal at spaced intervals along the web. This process forms a series of horizontally disposed pouches having opposed sidewalls separated by the vertical seals with each pouch being unsealed along a top edge. The pouches are then opened by separating the opposed sidewalls and are then filled with a product. After the pouches are filled, the top edge of each pouch is sealed together to enclose the filled pouches by training the pouches onto a horizontal rotary sealer having a heated circular sealer plate and progressively forming a continuous horizontal seal as the top edge of each pouch is being continuously moved along with a circumference of the heated circular sealer plate while at the same time applying an adequate temperature to provide a sealing action and allowing the top edge of each pouch to be joined together and smoothly sealed to enclose the filled pouches. This sealing method enables the packages to receive a greater amount of fill while still being able to provide a smooth, uniform seal.
