Abstract: Disclosed is a facility for plasma-assisted chemical vapor deposition, on an inner wall of a polymer container, of a thin barrier layer, and a method for adjusting the facility. The facility includes: an enclosure mounted in a conductive recess; a device for injecting precursor gas into the enclosure; a microwave generator; and a device for diffusing microwaves in the enclosure, connected to the microwave generator, energizing and maintaining a plasma in the precursor gas. The solid-state microwave generator has variable microwave emission frequency. The facility includes a sensor measuring the energy intensity of the plasma produced in the container. The facility includes a control unit connected to the sensor and to the microwave generator, the control unit being programmed to adjust the microwave emission frequency, via the variable frequency drive, in accordance with the value of the physical quantity characterizing the energy intensity measured by the sensor.

Abstract: Disclosed is a device for transporting plastic-container preforms, the device including an endless circulating element having an outer surface and being capable of moving the preforms along a path by rubbing against the preforms, the device including a stationary mounting defining a planar bearing surface for the preforms, the circulating element having a series of brushes which extend projecting from the outer surface, capable of engaging with the preforms in order to move same by rubbing.
