ABSTRACT:
Movable conveyor slats (10, 10′) have side parts (14, 14′, 16, 16′) which rest on top parts (94) of bearings (92). The bearings (92) have a generally U-shaped cross section and they fit on wings (72, 74) which extend outwardly and upwardly from the sides of a fixed conveyor slat (12). The movable slats (10, 10′) have a web (22, 24) and lower flange portions (26, 28) which with the side parts (14, 16) form laterally outwardly opening channels. The wings (72, 74) and the bearings (92) are received within the channel spaces.
