This is a machine for making standing pouch and 3-side sealed pouch. This machine employs 2 AC servo motors for film feeding and one independently operating AC servo motor for the up and down movement of the sealing units. The sealing time is set separately and remains constant independent of the running speed. Format changes are very fast and wastage is reduced to a minimum due to the easy, user-friendly loading of parameters by personal computer. The individual set-ups are stored in the computer for future reference and can also be output on the lineprinter if desired.
