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.

Abstract: A motorized roller for a conveyor includes a non-rotatable portion and a roller portion that is rotatably driven relative to the non-rotatable portion via an internal motor. The non-rotatable portion includes hubs or ends that are mounted to the opposed surfaces of opposite sidewalls or mounting portions of a conveyor, such that the motorized roller is positioned entirely between the mounting portions. The motorized roller may be secured to the mounting portions via at least one fastener extending through the mounting portions and at least partially into the respective hub or end of the non-rotatable portion of the motorized roller. The motorized roller may include an electrical connector integral with one of the hubs for electrically connecting the motorized roller to a corresponding connector of the conveyor. The motorized roller thus may be generally flush-mounted between the mounting portions of the conveyor.
