An endless belt operatively mounted beneath a load carrying backing member has a lower run moving across a generally planar fixed support surface, in frictional contact therewith. The belt may comprise a woven belt with reinforcing threads. A plenum chamber intermediate of the backing member and the fixed support surface includes a thin-flexible film sheet as the bottom element thereof bearing a plurality of small diameter perforations. The plenum chamber being subject to low pressure air creates a frictionless air film between the film and the belt lowe...
In an air pallet for movement of a load relative to an underlying generally planar fixed support surface, said air pallet comprising a generally rigid, generally planar backing member for supporting said load thereon and underlying said load, means including a plenum chamber intermediate of said backing member and said support surface for jacking said load and creating a frictionless air film beneath said backing member and said load, the improvement comprising: an endless belt operatively mounted to said backing member for movement in loop form and havi...
