Abstract: A boost drive that decreases the belt tension at otherwise high-tension locations along the conveying path of a modular plastic conveyor belt. The boost drive includes first and second drive wheels arranged to rotate about parallel axes transverse to the direction of belt travel. The drive wheels engage the top and bottom sides of the belt near a side edge of the belt. A drive mechanism drives the wheels in tandem, which provide a drive force to the belt that supplements the primary drive force and decreases tension in the belt.
