In installations for the shrink-foil packaging of palletised goods stacks, a considerable quantity of hot gases is costly and is very troublesome operationally. The invention reduces these influences by intercepting the hot gases, after their first contact with the foils (4) to be shrunk, in order then to discharge some of their heat and the particular foil covers (4) to be shrunk next. This results in a lowering of the gas temperatures and a preheating of the foils (4). The invention provides circuits having regenerative and recuperative heat transfers. <IMAGE> |
