ABSTRACT:
A vertical form, fill and seal packaging machine is described for forming a flat strip of packaging material into a tube and for filling the tube with solid and liquid products which mix in situ within the bags thus formed. Folding blades form gussets in the tube between parallel spaced apart front and rear tube forming surfaces. Sealing jaws seal the filled bags transversely, along the top and bottom edges. Additional pair of jaws seal the gusset material to the side panels at the bottom of the bag causing the gussets in that area to conform to a flat bottom portion of the bag. Additional jaws seal the walls of the bag together to provide a locating seal to keep the product in about the center of the bag and preventing it from falling to the bottom of the bag.
