The invention relates to a method and a coating device for applying a cladding layer on the inside of a carrier layer during the production of a multilayer heavy-duty pipe, said device comprising a pressure-exerting unit (22) having a force- application unit. A stable application of the cladding layer is achieved in that the coating device comprises a roll-on tool (2) having the pressure-exerting unit (22) and the force-application unit and in that the pressure-exerting unit (22) is provided with at least one pressure roller (20) that has a smaller diameter than the inside diameter of the heavy-duty pipe to be produced and is provided with at least one support element that diametrically counteracts the pressure roller during operation by means of a supporting force. |
