Abstract
A conveyor comprises two parallel endless chains (20, 21) carrying flights (22, 23), and guide tracks (24, 25) for the chains in a forwarding run consist of an inner guide track (24) and an outer guide track (25) with respect to the direction in which the flights (22, 23) project from the chains, the guide tracks (24, 25) also being disposed so that one chain (20) overlaps the other (21) in the direction transverse to the direction in which the flights project. The guide tracks (24, 25) are formed by channels (29) with low-friction liners (31) in a single elongate guide member (30) secured to a frame member (32) by bolts (33).
