US Patent 7246695 Conveyor apparatus for conveying closure

A conveyor apparatus for conveying and orienting multi-diameter plastic closures includes a conveyor belt having a plurality of conveyor flights each having a channel configuration. Each conveyor flight includes a pair of spaced apart sidewalls which are spaced apart by a distance greater than a portion of the associated closure having a smaller diameter, but by a distance less than a larger diameter of the associated closure. By this arrangement, whereby each conveyor flight is engageable with each of the closures at generally diametrically opposed portions thereof, efficient and consistent handling and orientation of multi-diameter closures is facilitated.
