A conveyor assembly insertable within a conveying system including a low friction conveying surface having both forward and lateral conveying forces for moving articles toward a parallel lateral sidewall and a downstream conveyor. A first diverging sidewall gradually converges parcels toward the center of the conveyor. An inwardly directed offset extends from a first diverging sidewall to a second lateral sidewall for shifting parcels inwardly toward a second lateral sidewall. A raised high friction conveying surface or rail belt extends along an outer edge of the low friction conveyor. At least a portion of the high friction belt is raised above the surface of the adjacent conveying surface in flow communication with the low friction conveying surface. Parcels contacting the high friction belt are prevented from shifting over toward the sidewall and parcels having a center of gravity outside the tipover point fall over the belt onto a recirculation conveyor.
