The invention concerns a method which consists in: inserting the upper part of the articles into a transport channel (5) comprising in its lower surface a continuous longitudinal opening (6), and generating on the articles, at least outside the transport channel (5), transporting air jets (J) enabling to drive the articles along the transport channel; permanently inputting inside the transport channel (5) and over its entire length, clean air directed mainly vertically and towards the lower surface (4a) of the transport channel, thereby limiting the risk for the articles (B) and the transport channel (5) to be contaminated.
