ABSTRACT:
An improvement in method and apparatus for continuously folding, heating, and tacking to the sides of the package panel the excess packaging material created by forming the package from a web of polyfoil material is disclosed. The method and apparatus is particularly useful in form, fill, and seal machines that form a plurality of aseptic sealed packages from a continuously advancing tube filled with a product, and incorporate a plurality of package receiving means mounted on a continuously advancing structure that forms sealed product filled packages into rectangular finished bricks by squaring the package, heating the excess material, folding the excess material against the package until it cools to thereby tack it.
