There are two types of CLDR, Roll to Roll and Continuous Chain.
Roll to Roll CLDR uses two sprockets on each roller. The two sprockets are connected to the adjacent rollers in a staggered patter through out the conveyor. Continuous Chain has a single sprocket per roller. It is driven by one chain that engages the top or bottom teeth of the sprockets.
