A method for installing a cover of at least one anode in an electrolytic cell used for the production of aluminium, by means of a service machine which is movable relative to the cell , the cell comprising a molten electrolytic bath in which an anode block of the anode is partially immersed, such that an upper surface ( S sup ) of the anode block emerges out of the bath , the service machine comprising at least one device for dispensing a product for covering the anode block , the method comprising at least the following steps: /1/ layer deposition of a controlled amount of the covering product by the dispensing device over at least one area (A n ) to be covered of the upper surface (S sup ) of the anode block ; /2/ measurement of the thickness of the covering product layer which is deposited in said area (A n ) to be covered by at least one thickness sensor on board the service machine ; /3/ comparison between the thickness measured by the sensor and a reference thickness, the reference thickness being predetermined to allow the covering product to cover the upper surface (S sup ) of the anode block over a given height in at least said area (A n ) to be covered; /4/ calculation of a corrective amount of covering product to reach the reference thickness in said area (A n ) to be covered; /5/ rectification of the thickness of the layer of the covering product in said area (A n ) to be covered using the corrective amount, a method in which prior to the deposition step /1/, a step of meshing at least one part of the upper portion of the carbon block defining a plurality of areas (A n ) to be covered by the covering product, a method in which at least one part of the /1/ deposition, /2/ measurement, /3/ comparison, /4/ calculation and /5/ rectification steps are carried out together in sequence, each step being applied for several of the areas (A n ) to be covered before proceeding to the next step. /1/ layer deposition of a controlled amount of the covering product by the dispensing device over at least one area (A n ) to be covered of the upper surface (S sup ) of the anode block ; /2/ measurement of the thickness of the covering product layer which is deposited in said area (A n ) to be covered by at least one thickness sensor on board the service machine ; /3/ comparison between the thickness measured by the sensor and a reference thickness, the reference thickness being predetermined to allow the covering product to cover the upper surface (S sup ) of the anode block over a given height in at least said area (A n ) to be covered; /4/ calculation of a corrective amount of covering product to reach the reference thickness in said area (A n ) to be covered; /5/ rectification of the thickness of the layer of the covering product in said area (A n ) to be covered using the corrective amount, a method in which prior to the deposition step /1/, a step of meshing at least one part of the upper portion of the carbon block defining a plurality of areas (A n ) to be covered by the covering product, a method in which at least one part of the /1/ deposition, /2/ measurement, /3/ comparison, /4/ calculation and /5/ rectification steps are carried out together in sequence, each step being applied for several of the areas (A n ) to be covered before proceeding to the next step. <EOS>
