Abstract
A chain conveyor which moves along a curved path comprises a conveyor chain (1) formed of plate links (3), which are hinged to each other, and a track (2) on which the links (3) slide. The track (2) is made of plastics material in which a magnetic strip (6) is embedded. The strip (6) is made of magnetic powder bonded with plastics material and the remainder of the track (2) has ferromagnetic powder incorporated in it. The links (3) are ferromagnetic and thus a magnetic field passes through the track (2) and the link (3) to hold the conveyor chain (1) in contact with the track (2) especially where the track is curved. Where the track is curved the magnetic strip (6) is preferably at the outside of the curve.
