A multistage multi-lane singulator conveyor system for separating side by side packages in stages. A first high friction surface conveying moving articles forward is adjacent a second low friction conveying lane in lateral flow communication having both forward and lateral conveying forces urging parcels forward and away from the first conveying lane, wherein the second conveying lane can be level or transversely inclined and angled upward in lateral flow communication with a third high friction surface conveying surface. Controlling residence time and forward and lateral movement of articles by assembling high friction surface conveying lanes and low friction surface conveying lanes in an end to end and/or lateral arrangement in flow communication with one another and/or shifting articles moving forward and laterally by staggering the high friction conveying surfaces and low friction conveying surfaces and adjusting the width by adjusting the number of high friction conveying surfaces adjacent one another.
