Filling machine fills packaging in “to level” system. Gravity poured assisted by vacuum allows for a smooth filling. Excess of product is directed to the overflow tank through the overflow wire. Pneumatic membran pump reverses poured product from the overflow tank to the supply tank. The use of vacuum speeds up the filling. The device operates in a linear system. Empty containers are carried to filling machine by lamellar conveyor. The sensor counts the corresponding number of packages, depending on the amount of fillers, and then closes the input lock. Followed by a series of filling. Packages are positioned with the positioning comb and pourers are lowered. After that the process of pouring “on the level” begins. After completion of pouring, pourers rise up, positioning comb “releases” the packages, the output lock opens and filled packages leave the filling machine.
