Abstract: A traveling band screen has a support frame assembly, two continuous chains movably mounted to the support frame assembly for motion along respective mutually parallel endless paths, a plurality of mesh members each secured on opposing edges to the chains, and a plurality of rollers rotatably mounted to each of the chains. One or more of the rollers are split rollers. Each such split roller has a respective rotation axis extending perpendicularly to the respective chain and accordingly to the path of motion of the chin. Each split roller has two roller halves secured to one another via elongate fasteners that extend parallel to the respective roller rotation axis.
