Conveyors and methods for operating conveyors to accelerate laterally adjacent conveyed articles over different distances. The conveyors provide a conveying surface atop rollers in a conveyor belt. The belt rollers ride on a bearing surface underlying the belt on a carryway. As the belt advances, the rollers riding on the bearing surface rotate in a direction of rotation to accelerate conveyed articles along the belt in the direction of rotation. The bearing surface is shaped so that its length in the direction of belt travel varies across the width of the conveyor.
