<p>A bend segment (1,2) for a chain conveyor comprising a chain movable over a track (1,2) including one or more bends, said chain being composed of links (5) of a magnetizable material having a substantially rectangular load bearing surface, the successive links (5) in the chain being pivoted together (6,7). The bend segment (1,2) includes means (15,15') for producing a magnetic field to retain the load bearing surfaces (5) of the links flat on the track (1,2), which consists of a pair of rails of (3,4) a magnetizable material wherebetween are provided, at predetermined distances, members (8) for interconnecting the rails (1,2) and/or for keeping these spaced apart. A synthetic plastics strip (11,12) is provided in at least the inner bend of the bend segment (1,2) against the inside of the rail. The means (15,15') for producing a magnetic field include magnets (15,15') placed between the rails (1,2), with the magnetic lines of force of the magnetic field produced by the magnets extending through the rails to attract the chain links (5) against the rails (3,4). </p> |
