ABSTRACT:
A chain conveyor includes a plurality of load rollers, a plurality of drive rollers, which are arranged in pairs, and a pair of spaced apart rows of interconnecting linkages aligned generally parallel to the longitudinal axis of the chain conveyor. The load rollers and the drive rollers are rotatably mounted between the linkages with the load rollers positioned between the pairs of drive rollers. The diameter of each load roller is larger than the diameter of each drive roller. The load rollers and the drive rollers are spaced along the longitudinal axis wherein the chain conveyor includes gaps between the outer surfaces of adjacent load rollers and between the outer surfaces of adjacent driver rollers. The chain conveyor further includes a clip, which is supported by the load rollers and includes a substantially rigid body, which has an upper surface spanning between the outer surfaces of adjacent load rollers with a length along the longitudinal axis greater than the gap between the adjacent load rollers to thereby substantially close the gap between the adjacent load rollers. The body also includes a lower surface, which spans between the outer surfaces of adjacent load rollers and has a length along the longitudinal axis greater than the gap between the adjacent load rollers to thereby prevent the clip from being ejected from between the adjacent load rollers.
