Process for manufacturing dimensionally stable profile sections (2) from plastic extrudates, in particular profile sections for windows, provided with protective coatings and/or devices (19, 55, 59, 65) for sealing, damping, covering etc., parts of profile sections or with elastically deformable sealing and/or damping devices (19, 55, 59, 65) which have a higher modulus of elasticity. The profile section (2) is extruded and the protective coating and/or device or sealing and/or damping device (19, 55, 59, 65) are extruded onto the profile section (2) in one and the same operation. On leaving the nozzle (4), the profile section (2) is calibrated and cooled at least until it becomes deformable. A surface region of the profile section (2), on which the protective coating and/or device or sealing and/or damping device (19, 55, 59, 65) are applied, is heated until it at least forms a paste, the protective coating and/or device or sealing and/or damping device (19, 55, 59, 65) are extruded onto the heated region. The extruded profile section (2) is then gripped by a withdrawal device (6). |
