ABSTRACT:
Objects such as pieces of mail are stacked without making significant mechanical contact with the objects by an apparatus producing a laminar flow of air over a surface which defines or parallels the desired path of movement for the objects. The objects are placed to form a barrier between the laminar air flow and ambient air so that movement, such as turning an edge of the object to prevent impact on other objects and regulation of direction velocity and kinetic energy of the motion of the objects, may be guided by the Coanda effect of the laminar flow of air. The placement of the objects thus provides an acoustic barrier to reduce the generation and propagation of noise by the high pressure air used to create the laminar flow of air. An air amplifier reduces the volume of high pressure air required to control the movement of the objects.
