Abstract
A planar air pallet supports a load for frictionless transport on a backing member which overlies a fixed support surface. The pallet employs at least one sheet of flexible plastic film underlying the load and backing member and overlying the support surface and being perforated except for the perimeter to effect controlled pillowing of that flexible plastic film sheet and carries external air dispersion elements such as slats, ribs or strips. The dispersion element may take the form of a thin piece of cardboard to the side of the load adjacent the air inlet to the plenum chamber and may comprise a folded over portion of a generally rigid planar sheet forming a fixed support surface.
