Abstract: The method serves to form a train of articles, e.g. plastic bottles, which articles are transported in a conveyor line while being suspended and propelled along the line in a given transport direction under drive from transport air jets. The method comprises the following successive steps implemented in a segment of the conveyor that is referred to as a train-forming segment: a) articles are accumulated in at least a downstream zone of the train-forming segment under drive from transport air jets in an upstream zone of the segment, and by the articles in the downstream zone being braked (and optionally stopped) by drive from air; b) interrupting or reducing the power of the transport air jets in the upstream zone of the train-forming segment so that the articles present in said upstream zone do not penetrate into the downstream zone, while accelerating (or starting) a train of articles under drive from transport air jets in the downstream zone of the train-forming segment.

Abstract: The conveyor comprises two spaced-apart under-neck guides (3) along which articles are designed to be transported by being suspended via their collars (2) on the under-neck guides (3), and also a longitudinal stop (6) which is mounted above the under-neck guides (3) and which serves to limit the up stroke available to the articles between the under-neck guides (3). In a preferred embodiment, the top abutment is in the form of a stop (6) having an abutment-forming bottom longitudinal face (6a) in which there is formed a longitudinal central channel (6b) of width (L) that is less than the diameter (D) of an article at its top end (1d).
