Abstract:
A method of continuously forming, filling and sealing of packages with a continuous web of film material, comprising the steps of:a) providing a continuous web of film material;b) folding the web to provide confronting sides joined along a bottom edge;c) forming a vertical seal at spaced intervals along the web thereby providing a series of horizontally disposed adjoining pouches having opposed sidewalls with each pouch unsealed along a top edge;d) opening the pouches by separating the opposed sidewalls;e) filling the pouches with a material; andf) sealing the top edge of each pouch together to close 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,said horizontal rotary sealer having means to provide a vertical support to said continuous web of film material such that said means to provide a vertical support to said continuous web of film material contacts only said vertical seal of said pouch without contacting confronting sides of said filled pouch so that disturbance of the material within said pouch is minimized as the top edge is sealed.
