Abstract (en)
[origin: FR2791962A1] The invention concerns a conveyor belt (1) operating as a deep semicircular trough provided with a covering belt (2), characterised in that the covering belt (2) is planar in inoperative state, except for its continuous sealing loops (8) and has a width (a) linked to the length (L) of the trough-shaped conveyor belt (1), at the angle ( delta ) formed by the flexible covering belt (2), relative to the horizontal and to the length (b) of the continuous sealing loop (8), by the relationship a = L.cos delta +2b, and a sealing device (5) is formed by said longitudinal loop (8), being urged to enclose, by automatic engagement, each of the longitudinal ends (6) of said conveyor belt (1), and the disengagement, in the proximity of the unloading zone (Zd) is obtained by simple release, under the effect of the opening of the trough angle ( alpha ) and the separation force between said belts (1, 2) without the intervention of any mechanical means.
