Abstract
Abstract This invention provides a method for the mechanical handling of goods in which the goods are stacked upon a flat flexible pallet, in the form of an envelope with a mouth at one end, which takes up very little space and which will not support the goods when the goods are to be moved. To lift the goods the pallet is partially inflated through the mouth by blowing air into the envelope and a rigid supporting member is introduced into the envelope through the mouth so that the goods can be lifted, moved and put down again whereupon the supporting member can be removed and the air supply turned off so that the pallet lies flat again.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
A method for mechanical handling of goods comprising the steps of: placing said goods upon the upper surface of a normally flat inflatable envelope having an open mouth at one end, introducing a rigid separator member to said mouth, injecting gas under pressure into said envelope from the leading edge of said separator member to partially inflate said envelope to slightly lift said goods, inserting said separator member into said envelope into a support position beneath said goods while continuing to inject gas under pressure, and handling said goods by moving said envelope with said goods placed thereon by means of said separator member.
Claim 2
Independent Claim
104 words
A method for mechanical handling of goods comprising the steps of: placing said goods upon the upper surface of a normally flat inflatable envelope having an open mouth at one end, introducing a rigid separator member to said mouth, injecting gas under pressure into said envelope from the leading edge of said separator member to partially inflate said envelope to slightly lift said goods, inserting said separator member into said envelope into a support position beneath said goods while continuing to inject gas under pressure, and handling said goods by moving said envelope with said goods placed thereon by means of said separator member.
