Abstract: A diagnostic method for a container processing machine including a rotating conveyor, and processing units carried by the rotating conveyor and designed to engage at least one container to carry out processing operations is disclosed. The method includes operatively coupling a first set of monitoring sensors to the processing units on-board the processing machine to monitor relevant operating parameters. The method also includes controlling the processing units to execute test operations in lieu of processing operations. The method further includes acquiring measurement data from the first set of monitoring sensors during the test operations. The method further includes processing the acquired measurement data to provide maintenance information on the reliability of at least one of the processing units or the processing machine.

Abstract: There is disclosed a container processing machine comprising a material handling surface for handling a sheet-like material through suction and a vacuum source in fluid connection with said material handling surface, the machine including means for detecting and transmitting a value of pressure of the gas being suctioned; a controllably operable flow valve; a control unit operatively connected with said detection and transmission means and with said flow valve; said detection and transmission means and said flow valve being arranged between said vacuum source and said material handling surface; said control unit being programmed to adjust the degree of opening of said flow valve in response to a signal which is a function of at least said value of pressure.

Abstract: The present invention relates to a pressurization device, in particular of the type used for high hydrostatic pressure. More particularly, the present invention relates to a pressurization device (1) comprising a casing (4) provided with a closure (3) and housing a pressurization chamber (15), the device (1) being provided with pressurization means for putting the pressurization chamber (15) under pressure, characterized in that the pressurization chamber (15) is sealed by means of a plurality of annular seals (19a, 19b, 19c) arranged in series on the lateral surface of the pressurization chamber (15) at predetermined relative distances (D1, D2) which are correlated with the coefficient of compressibility of the liquid filling the pressurization chamber (15).

Abstract: The present invention relates to a hydraulic pressurization system, in particular for application to pressurization devices operating in accordance with the high hydrostatic pressure principle. In particular, the present invention provides a pressurization system for modifying the pressure in a pressurization device. The system comprising a first hydraulic circuit in which one or more primary pressure accumulators are connected to the pressurization device in controlled manner in order to permit a substantially incompressible fluid to be admitted to and removed from the pressurization device at a first pressure, the primary pressure accumulators being precompressed-gas pressure accumulators.
