Abstract

A fluid conveyor effects movement of articles, such as cans, along a predetermined path adjacent to a thin deck plate. The thin deck plate has fluid distribution areas formed therein with each fluid distribution area having an aperture formed therein, after which a flat tab section is formed that is inclined with respect to the remainder of the plate. Each tab section therefore has an aperture therein through which fluid from a fluid supply unit is injected under pressure into the article path adjacent to the plate in a direction and angle determined by the orientation of the tab sections to effect movement of articles along the article path. Each tab section has a portion integral with the remainder of the plate and side and end edge portions unattached to the remainder of the plate but sufficiently contiguous thereto to prevent passage of air between the edge portions and the remainder of the plate. The fluid conveyor can also include one or more turns between upstream and downstream sections, with first and second groups of tab sections being positioned to inject fluid in the upstream section to effect article movement and with the second group of tab sections being positioned i…
