ABSTRACT:
A belt conveyor or belt accumulator includes at least two tandem zones, each of which is defined by a motorized roller and at least one idler roller positioned along and between opposite sidewalls of the conveyor and a continuous belt routed around the motorized roller and the idler roller or rollers. The motorized roller is operable to drive the belt around the rollers to move articles along the respective zone. The belt may have a low modulus characteristic and may be initially stretched at least 0.75% in its lengthwise direction when the belt is reeved or routed around the rollers. The motorized roller of each zone may be independently operable, such as in response to an article sensor at each zone, to convey or accumulate articles on the respective zone of the belt conveyor.
