Abstract: A method and apparatus for the feeding and accumulation of bottles in an air conveyance system, which has a swing-arm air conveyor with a flexible guide joint which allows the efficient conveyance of bottles from a single-lane source of bottles to a plurality of recipient air conveyors for accumulation and handling. The swing-arm air conveyor also includes a second flexible guide joint which provides for the delivery of the bottles to the recipient air conveyors in a direction parallel to the direction of the single-line source of bottles. The apparatus and method is also used for the conveyance of bottles from a plurality of feed air conveyors to a single-lane recipient air conveyor. The flexible guide joint allows the swing-arm air conveyor to be pivoted while still maintaining a continuous chamber through which bottles are conveyed.
