HANDLING SYSTEM

摘要

A planar air pallet supports a load for frictionless transport relative to an underlying fixed support surface. A single sheet of flexible plastic film may underlie a stack of cartons forming the load with the edges sheet heat shrunk about the stack of cartons. Small diameter perforations are provided at least within that portion of the sheet underlying the lowermost tier of cartons to form a plenum chamber, preferably through air dispersion members between the flexible sheet and the carton load. The perforations unrestrictedly open directly to said plenum chamber. Pillowing of the sheet portion of the plenum chamber is controlled to permit jacking of the load sufficiently for a combination of surface irregularity for both the load support surface and the backing surface. The air pallet may also comprise a flexible film bag, which carries internally a rigid sheet which may be the load to control pillowing and provide air dispersion.
