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).
