  • Confinement method and device in particular for a special atmosphere in a space for continuously processing articles fed therethrough
    Patent number: 5934992
    Abstract: The present invention relates to a method for confining an atmosphere (B) in a space (4) communicating with its surroundings via at least one opening. A gas curtain (1+2) comprising a low-velocity jet (2) and a high-velocity jet (1) is generated at said opening. Characteristically, a fraction of the flow in said low-velocity jet (2) is injected into the confined atmosphere (B) and adds to the induced flowrate of said low-velocity jet (2), the size of said fraction being variable depending on the pressure within said space (4). The present invention also relates to a device for carrying out said method.
