  • a primary passage for example a slit or an opening or a bypass duct, which extends along the work path and connects together the drying chamber and the forming chamber
  • a compression unit for supplying pressurized air into the forming chamber
  • an air-suction unit which is connected to the drying chamber.
  • a machine of the type referred to above is frequently subjected to cleaning and sterilization cycles, typically, but not exclusively, at each end of production, which is followed, in particular, by a machine stoppage, in order to restore therein an aseptic production environment.
  • the sterilization cycle of the drying and forming chambers referred to above is carried out using peroxide steam mixed with air.
  • the present applicant has been able to note that the containers produced by the machine may at times not meet the requisites of sterilization envisaged, notwithstanding the cleaning and sterilization cycles systematically conduction prior to start of a new production cycle.
  • the sterilization cycle using peroxide steam conducted for the drying chamber and the forming chamber requires the temperature of the walls of each chamber to be below the dew point of the peroxide steam in order to guarantee that the peroxide will wet the aforesaid walls and will thus bring about an effective action of sterilization.
  • the present applicant has hence understood that it is necessary to provide an improved operation of cooling of the two chambers to solve the aforesaid technical problem regarding production of containers that meet the sterilization requisites envisaged.
  • the present applicant has, however, understood that, instead of providing a new cooling system, it is possible to overcome the limits referred to above of the conventional cooling operation by balancing in a different way the flow of air during the cooling operation.
  • a first position is said to be "upstream” of a second position when the first position precedes the second position with reference to the direction of feed of the object; vice versa, the second position is said to be “downstream” of the first position in so far as it follows the first position once again with reference to the direction of feed of the object.
  • passage refers generically to a path of flow for a fluid, for example air.
