    摘要: Apparatus is described for coating of three dimensional objects such as glass jars or bottles, during a continuous manufacturing process, by Chemical Vapour Deposition (CVD). The objects pass through tunnel having one or more vertical arrays of nozzles located in the sidewalls. The nozzles deliver CVD precursors and, being independently variable, allow for variation of the precursor concentration along the height of the object. Thus, the thickness of the resultant coating may be so varied. Preferred embodiments include corresponding exhaust arrays, aligned with the nozzles and one or more air curtains which isolate the interior of the tunnel from the external environment.
