A belt conveyor comprises an endless conveyor belt (4) of the type surrounding the material conveyed and having a central part (5) and two edge parts (6, 7) connected thereto. The edge parts are substantially flexurally rigid in the transverse direction of the belt. The belt conveyor further comprises a frame having support rollers for carrying the belt along at least part of its path. The one edge part (6) of the belt (4) is divided into two portions closest to its free longitudinal edge so as to form a longitudinal pocket open towards the free longitudinal edge. The free edge portion of the other edge part (7) is received in the pocket so as to be substantially unable to rotate therein, and is forcedly retained owing to the connection of the edge parts to the central part. A rotary disc (15), tapering in the form of a wedge towards its periphery, is mounted in the frame so as to engage and widen the pocket to enable the introduction of the free edge portion of the other edge part (7) therein at a belt sealing location along the belt path. |
