A belt conveyor comprises an endless conveyor belt (5) which is substantially U-shaped in cross-section. The conveyor belt has a base portion (6) with a central, longitudinal bead (7) on the lower side and two substantially flat lateral portions (9, 10) joined to the base portion and rigid relative to the longitudinal axis of the conveyor belt. Furthermore, the belt conveyor has a plurality of rollers distributed along its goods conveying path and comprising on one hand supporting rollers (11) on which the bead (7) rests, and on the other hand lateral guide rollers (14, 15) which bear against the upper part of the outside of each lateral portion (9, 10) to retain this in a substantially vertical position such that the weight of the conveyor belt and of the goods (16) conveyed in the belt is absorbed by the supporting rollers via the base portion and the bead. |
