Abstract:
1. A plenum system, for use in conjunction with a conveyor belt system comprising a plurality of oppositely disposed conveyor belts which are disposed upon opposite sides of a conveyor belt flow path along which articles are to be conveyed, comprising: vacuum means, operatively associated with the conveyor belt flow path, for simultaneously withdrawing ambient air, present along the conveyor belt flow path along which the articles are to be conveyed by the plurality of oppositely disposed conveyor belts, in opposite directions from the conveyor belt flow path so as to prevent the generation of tip vortices upon the articles, when the articles are conveyed along the conveyor belt flow path, such that destabilizing forces, normally resulting from the generation of the tip vortices, are not impressed upon the articles being conveyed along the conveyor belt flow path, whereby the articles are able to be conveyed along the conveyor belt flow path at an enhanced rate of speed.
