In conduit scraping conveyors, e.g. for conveying food to a plurality of feeding places in a stable, a flight conveyor cable is advanced through a tubular system for forwarding material by the help of flight discs on the cable. The cable should be a cored steel cable, that however has a tendency of expelling wire pieces that in an extremely undesirable manner is mixed with the material. Steel cables are already known that are surrounded by a covering layer of extruded elastomer that could prevent the release of wire pieces, but these cables are not immediately suitable for being provided with moulded flight discs that ought to be in firm connection directly with the steel cable. It is by the invention realised that a cover coated flight conveyor cable however can be provided by making use of an injection moulding technique, by which the flight discs (2) in a known manner is moulded in a relatively stiff or rigid elastomer directly on the steel cable (1), but also having short thin outwardly extending sockets (2a) at both sides of the flight discs (2), and that there between the neighbouring flights (2) and over the sockets (2a) is moulded a bendable elastic coating layer (3), preferably a thermoplastic elastomer, as this can retain its tight connection to the sockets (2a) and the cable (1). <IMAGE> |
