1. A controlled speed single file conveyor for conveying upright substantially cylindrical articles at a controlled speed from an upstream location to a downstream location, said single file conveyor comprising:

  • a deck plate extending from said upstream location to said downstream location, said deck plate having an upper surface, opposite inboard and outboard side edges spaced at a lateral distance, and an underside;

    a plurality of rows of louvers, each having a width, communicating said upper surface and said underside, extending generally parallel to said side edges from said upstream location to said downstream location, at least some of said rows of louvers being angled so that air discharged through said angled rows of louvers has a force vector component toward said inboard side edge and a force component vector in a downstream direction;

    a plenum connectable to a pressurized source of the air and is attached to said underside of said deck plate;

    a vertical wall positioned above said deck plate adjacent and substantially parallel to said inboard side edge, said vertical wall having a lower edge positioned at a height above said upper surface; and

    means for adjusting said height of said lower edge of said wall above said deck plate to control the amount of the air from said rows of louvers being exhausted over said inboard edge by passing under said wall.
