Abstract
A curved belt conveyor includes at least two zones, each of which may be defined by a motorized roller and at least one idler roller which are positioned along and between opposite sidewalls of the conveyor, and a continuous belt reeved around the rollers. The conveyor includes a tracking means for tracking the belt on the rollers. The tracking means is substantially contained between the sidewalls of the conveyor and laterally inward of the outer and inner ends of the rollers. The tracking means may comprise a tracking roller positioned along a lower surface of one of the rollers and may engage the lower run of the belt with an upper surface of the tracking roller to maintain the belt in a proper position around the rollers.
