Abstract (en)
[origin: WO2017192329A1] Components of a conveyor system designed to reduce take-up tension in a returnway of a conveyor. A snub roller in the returnway engages and drives a portion of the conveyor belt at a speed that is faster than the speed of a drive for the conveyor belt. A weighted roller between a drive and a synchronized sprocket tied to the drive alternatively reduces take-up load in a conveyor belt.
