  • Stationary tucker bar mechanism
    Patent number: 7254930
    Abstract: A stationary tucker bar mechanism attached to a vertical form, fill, and seal packaging machine used to construct a vertical stand-up pouch and a gusseted flat bottom bag. The invention involves producing a vertical stand-up pouch or flat bottom bag from a single sheet of packaging film by forming one or two vertical creases along opposing sides of the packaging film tube prior to forming a transverse seal on the tube. The vertical crease is formed using the stationary tucker bar gusseting mechanism positioned outside the packaging film tube and positioned between two forming plates located inside the packaging film tube. While the tucker bar gusseting mechanism is stationary during operation, it is fully adjustable along multiple axes of orientation.
