<p>A vacuum transfer conveyor apparatus is provided for transferring containers (52) from one elevation to another having a plenum wall (W) against which a transfer belt (60) traverses, which wall (W) is provided with a plurality of parallel longitudinal slots (92,98,198,112) which extend from larger pick-up openings (94) at the upstream end of the plenum wall to the downstream end. These slots (92,98,108,112) are successively reduced in width and area from the upstream end to the downstream end. One portion of the vertical travel of the belt can be flat so as to improve the seal between the edge of the container and the transfer belt. The transfer belt (60 min ) may be provided with a deformable foam (114) surface which provides an improved seal between the edge of each container (52 and the transfer belt (60 min ).</p> |
