  • Multi-station rotary filling machines by weight dosing, generally comprise a rotating carousel mainly comprising a tank for the filling product, provided with filling heads, and weighing stations placed below these heads and functionally connected to the latter .
  • the containers to be filled are introduced continuously onto the weighing stations where they trigger the opening of the filling heads and, when the required weight of product has flowed from the tank into the containers, the weighing station emits a signal which causes the closure of the head with which it cooperates.
  • the full container is then evacuated to a closing and closing carousel.
