Abstract
To remove a layer of thermoplastic material, particularly of polyethylene, adhering to a substrate, particularly a strip of aluminum, there is directed against a region of the layer of thermoplastic material (2) a shaped jet (10) of hot inert gas, containing for example principally helium, to melt the thermoplastic material and the jet is displaced relative to the coated substrate to push back (11) the melted thermoplastic material. The gas or the gaseous between 300.degree. C. and 700.degree. C., by an electric resistance (20), adjacent the ejection nozzle (4).
