The fully automatic side sealer Universa 500 is the answer to almost all packaging requirements. Its name reveals the concept and objective for this universal film packaging machine. The encoder control by KALLFASS based on the Siemens S7 was realized for the first time in serial machine production. Complicated and time consuming fine tuning of timers with different product length or speeds are history. End users with constant product change-over appreciate the advantages of encoder controls. Manufacturing plants with a wide product range, as well as industrial service - and contract packagers, profit highly from a simplified production process.
