Abstract
A surface layer is applied to an elongated, deformable hollow profile. The profile originally has at least one wall portion which is curved as seen in cross section. The profile is advanced to a device for applying the surface layer and pressed so as to deform the curved wall portion into a shape which, as seen in cross section, is substantially straight. The surface layer is applied to this wall portion while it is in the substantially straight shape, and the profile is then at least substantially returned to its original shape.
