<p>In a stocking belts conveyor (1) an improvement is provided for avoiding the belts (25, 26) from sagging when the loading sections (25a, 25b) of their paths (P1, P2) are lengthened in order to vary the operating configuration of the conveyor (1). More particularly, the improvement consists of a flexible element (50) which comprises a pair of parallel chains (57) which support between them a plurality of rotatable rods (58); the flexible element (50) is guided along a path (P3) defined by a series of drive rollers (60, 60a, 60b) and extends between two ends (50a, 50b) fixed to an upper trolley (15) of the conveyor (1) so as to be able to support the said loading sections (25a, 25b) in the various operating configurations thereof. <IMAGE></p> |
