A belt conveyor comprises an endless and closed conveyor belt (1), which is flexible essentially merely about axes which are parallel with the transverse direction of the belt, guide means (11) for making part of the conveyor belt follow a substantially rectilinear main path (3), and a branch device (9), which is movable along the main path, for branching the conveyor belt from the main path via two branch paths (19, 20) which are parallel with a branch line (26), directed transversely of the main path, respectively to and from an arm, which is pivotable in a plane transversely of the branch line. The branch device (9) comprises two first deflection rollers (14, 23), which are offset in opposite directions transversely of the main path (3) and the axes of which are each perpendicular to a deflection plane through the centre of the respective deflection rollers, said plane intersecting the main path and the respective branch paths (19, 20) at a distance from the first deflection rollers.
