Abstract

The invention relates to a guide track (1) for a roller (2) with wheels (3), comprising first (5) and second (6) rolling paths along a direction. The guide track is characterized in that it comprises a first flexible lip (7), adjacent to said first path (5) and slanted relative to the latter, and a similar second lip (8), and in that the latter are separated by said paths or in that said paths are separated by said lips, together defining a V-groove. The invention also relates to a gravity storage and retrieval system for moving, under the weight thereof, such a roller (2) and comprises a loading station receiving and guiding said roller (2) to a sloped buffer that conveys the roller to an unloading station, said upstream loading station and said buffer each comprising at least one such guide track (1).
