A belt conveyor comprising - a curved conveyor belt (1) comprising a plurality of modules (2) connected together by pins (3) and shaped such that the belt is able to travel through both straight and curved paths, - and a support and guide element or track (4) for said belt, comprising at least one curved portion (4A), each module (2) comprising: - a front end (2A) and a rear end (2B), an upper surface (2C) and a lower surface (2D), and two sides (2E, 2F), - in which said front end (2A) and rear end (2B) comprise connection parts (5) comprising through holes (6), separated by apertures (7), - said connection parts (5) being disposed such that those parts provided in the front end can be inserted into the apertures provided in the rear end (2B) of an adjacent module to enable a connection pin to be inserted through the through holes (6) of the connection parts (5) of the two modules to connect them together, - and guide and connection means (3) for at least a plurality of the belt modules, with counter-means (8) provided in said belt support and slide element (4) at least at said curved portion (4A), to maintain the modules substantially in contact with said support and slide element (4) when the belt slides along said curved portion (4A), in said connection and guide means at least apart (3) of the modules (2) being made of a ferromagnetic material, and said counter-means comprising means to generate a magnetic field sufficient to maintain the modules (2) in contact with the support and slide element when the belt slides along said curved portion (4A).
