Abstract
The invention relates to a method and a coating device for applying a cladding layer onto the inner side of a carrier layer during the production of a multilayer heavy-duty pipe, with a pressure-exerting unit having a force application unit. A stable application of the cladding layer is achieved by having the coating device comprise a rolling tool with the pressure-exerting unit and the force application unit, and by providing the pressure-exerting unit with at least one pressure roller having a diameter that is smaller than the inside diameter of the heavy-duty pipe to be produced, and with at least one support element acting diametrically counter thereto with a supporting force in the operating state.
