Abstract

The invention refers to a method and a device for applying a coating onto an elongated object (2). The object is semi-continuously or continuously transported along a transportation direction from an arrangement (1) for depositing a coating comprising a molten metal onto the object (2) to an arrangement (3) for receiving the coated object (2). Means are provided to wipe off excessive coating in a longitudinal direction of the object substantially opposite to the transportation direction. A first moving electromagnetic field, generating a force acting on the molten metal coating towards a first lateral edge (15) of the coated object (2), is applied to the object (2). A second moving electromagnetic field, generating a force acting on the molten metal coating towards a second lateral edge (16) of the coated object (2) opposite to the first lateral edge, is applied to the object.
