Abstract
A conveyor continuously advances bundles issuing from a manufacturing line while manipulating them into a pattern for shipment. Comprised of three zones, the conveyor sequentially centers, rotates and organizes bundles for inclusion in a pattern in preparation for shipment without manual intervention. The conveyor is insensitive to bundle size within the parameters of the particular embodiment, and performs desired manipulation regardless of initial bundle placement or orientation. As no interruption in the flow of bundles is needed to manipulate bundles into patterns, no jamming of bundles occurs upstream from such patterns as they form. The conveyor increases the overall speed of handling bundles, and makes possible the automation of shipping procedures in manufacturing facilities.
