Method and apparatus for providing end seals on vertical stand-up packages

摘要

An improved method and apparatus for providing end seals on vertical stand up packages that prevents pleat formation and gusset variation. A clamping device is mounted below sealing jaws. A bottom end seal is made by the sealing jaws to form an open-ended tube. The open-ended tube is moved downward. The clamping device engages the tube to prevent twisting when product is placed into the tube. Product then enters an open-ended tube of flexible film packaging and the top seal is made.
